怎么用Android开发一个学生管理系统

本篇内容介绍了"怎么用Android开发一个学生管理系统"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

效果演示

随手做的一个小玩意，还有很多功能没有完善，倘有疏漏，万望海涵。

实现功能总览

实现了登录、注册、忘记密码、成绩查询、考勤情况、课表查看、提交作业、课程打卡等。

代码

登录与忘记密码界面

登录与忘记密码界面采用的是TabLayout+ViewPager+PagerAdapter实现的

一、添加布局文件

 View View_HomePager = LayoutInflater.from( Student.this ).inflate( R.layout.homeppage_item,null,false ); View View_Data = LayoutInflater.from( Student.this ).inflate( R.layout.data_item,null,false ); View View_Course = LayoutInflater.from( Student.this ).inflate( R.layout.course_item,null,false ); View View_My = LayoutInflater.from( Student.this ).inflate( R.layout.my_item,null,false );

private List Views = new ArrayList<>(  );

 Views.add( View_HomePager ); Views.add( View_Data ); Views.add( View_Course ); Views.add( View_My );

二、添加标题文字

private List Titles = new ArrayList<>(  );

Titles.add( "首页" );Titles.add( "数据" );Titles.add( "课程" );Titles.add( "我的" );

三、绑定适配器

/*PagerAdapter 适配器代码如下*/public class ViewPagerAdapter extends PagerAdapter {    private List Views;    private List Titles;    public ViewPagerAdapter(List Views,List Titles){        this.Views = Views;        this.Titles = Titles;    }    @Override    public int getCount() {        return Views.size();    }    @Override    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {        return view == object;    }    @NonNull    @Override    public Object instantiateItem(@NonNull ViewGroup container, int position) {        container.addView( Views.get( position ) );        return Views.get( position );    }    @Override    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {        container.removeView( Views.get( position ) );    }    @Nullable    @Override    public CharSequence getPageTitle(int position) {        return Titles.get( position );    }}

 ViewPagerAdapter adapter = new ViewPagerAdapter( Views,Titles );        for (String title : Titles){            Title.addTab( Title.newTab().setText( title ) );        }        Title.setupWithViewPager( viewPager );        viewPager.setAdapter( adapter );

注册界面

一、创建两个Drawable文件

其一

其二

二、将其添加数组内

private final int[] Identity = {R.drawable.press_oval_textview,R.drawable.notpress_oval_textview};

三、动态变化背景

 private void SelectStudent(){        mIdentity_Student.setBackgroundResource( Identity[0] );        mIdentity_Teacher.setBackgroundResource( Identity[1] );    }    private void SelectTeacher(){        mIdentity_Student.setBackgroundResource( Identity[1] );        mIdentity_Teacher.setBackgroundResource( Identity[0] );    }

考勤界面

主要是通过绘制一个圆，圆环、内圆、文字分别使用不同的背景颜色，并将修改背景颜色的接口暴露出来。

一、CircleProgressBar代码如下

public class CircleProgressBar extends View {    // 画实心圆的画笔    private Paint mCirclePaint;    // 画圆环的画笔    private Paint mRingPaint;    // 画圆环的画笔背景色    private Paint mRingPaintBg;    // 画字体的画笔    private Paint mTextPaint;    // 圆形颜色    private int mCircleColor;    // 圆环颜色    private int mRingColor;    // 圆环背景颜色    private int mRingBgColor;    // 半径    private float mRadius;    // 圆环半径    private float mRingRadius;    // 圆环宽度    private float mStrokeWidth;    // 圆心x坐标    private int mXCenter;    // 圆心y坐标    private int mYCenter;    // 字的长度    private float mTxtWidth;    // 字的高度    private float mTxtHeight;    // 总进度    private int mTotalProgress = 100;    // 当前进度    private double mProgress;    public CircleProgressBar(Context context) {        super( context );    }    public CircleProgressBar(Context context, @Nullable AttributeSet attrs) {        super( context, attrs );        initAttrs(context,attrs);        initVariable();    }    public CircleProgressBar(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {        super( context, attrs, defStyleAttr );    }    private void initAttrs(Context context, AttributeSet attrs) {        TypedArray typeArray = context.getTheme().obtainStyledAttributes(attrs,                R.styleable.TasksCompletedView, 0, 0);        mRadius = typeArray.getDimension(R.styleable.TasksCompletedView_radius, 80);        mStrokeWidth = typeArray.getDimension(R.styleable.TasksCompletedView_strokeWidth, 10);        mCircleColor = typeArray.getColor(R.styleable.TasksCompletedView_circleColor, 0xFFFFFFFF);        mRingColor = typeArray.getColor(R.styleable.TasksCompletedView_ringColor, 0xFFFFFFFF);        mRingBgColor = typeArray.getColor(R.styleable.TasksCompletedView_ringBgColor, 0xFFFFFFFF);        mRingRadius = mRadius + mStrokeWidth / 2;    }    private void initVariable() {        //内圆        mCirclePaint = new Paint();        mCirclePaint.setAntiAlias(true);        mCirclePaint.setColor(mCircleColor);        mCirclePaint.setStyle(Paint.Style.FILL);        //外圆弧背景        mRingPaintBg = new Paint();        mRingPaintBg.setAntiAlias(true);        mRingPaintBg.setColor(mRingBgColor);        mRingPaintBg.setStyle(Paint.Style.STROKE);        mRingPaintBg.setStrokeWidth(mStrokeWidth);        //外圆弧        mRingPaint = new Paint();        mRingPaint.setAntiAlias(true);        mRingPaint.setColor(mRingColor);        mRingPaint.setStyle(Paint.Style.STROKE);        mRingPaint.setStrokeWidth(mStrokeWidth);        //mRingPaint.setStrokeCap(Paint.Cap.ROUND);//设置线冒样式，有圆 有方        //中间字        mTextPaint = new Paint();        mTextPaint.setAntiAlias(true);        mTextPaint.setStyle(Paint.Style.FILL);        mTextPaint.setColor(mRingColor);        mTextPaint.setTextSize(mRadius / 2);        Paint.FontMetrics fm = mTextPaint.getFontMetrics();        mTxtHeight = (int) Math.ceil(fm.descent - fm.ascent);    }    @Override    protected void onDraw(Canvas canvas) {        super.onDraw( canvas );        mXCenter = getWidth() / 2;        mYCenter = getHeight() / 2;        //内圆        canvas.drawCircle( mXCenter, mYCenter, mRadius, mCirclePaint );        //外圆弧背景        RectF oval1 = new RectF();        oval1.left = (mXCenter - mRingRadius);        oval1.top = (mYCenter - mRingRadius);        oval1.right = mRingRadius * 2 + (mXCenter - mRingRadius);        oval1.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);        canvas.drawArc( oval1, 0, 360, false, mRingPaintBg ); //圆弧所在的椭圆对象、圆弧的起始角度、圆弧的角度、是否显示半径连线        //外圆弧        if (mProgress > 0) {            RectF oval = new RectF();            oval.left = (mXCenter - mRingRadius);            oval.top = (mYCenter - mRingRadius);            oval.right = mRingRadius * 2 + (mXCenter - mRingRadius);            oval.bottom = mRingRadius * 2 + (mYCenter - mRingRadius);            canvas.drawArc( oval, -90, ((float) mProgress / mTotalProgress) * 360, false, mRingPaint ); //            //字体            String txt = mProgress + "%";            mTxtWidth = mTextPaint.measureText( txt, 0, txt.length() );            canvas.drawText( txt, mXCenter - mTxtWidth / 2, mYCenter + mTxtHeight / 4, mTextPaint );        }    }    //设置进度    public void setProgress(double progress) {        mProgress = progress;        postInvalidate();//重绘    }    public void setCircleColor(int Color){        mRingPaint.setColor( Color );        postInvalidate();//重绘    }}

签到界面

签到界面就倒计时和位置签到

一、倒计时

采用的是Thread+Handler
在子线程内总共发生两种标志至Handler内，0x00表示倒计时未完成，0x01表示倒计时完成。

private void CountDown(){        new Thread(  ){            @Override            public void run() {                super.run();                for (int j = 14; j >= 0 ; j--) {                    for (int i = 59; i >= 0; i--) {                        Message message = handler.obtainMessage();                        message.what = 0x00;                        message.arg1 = i;                        message.arg2 = j;                        handler.sendMessage( message );                        try {                            Thread.sleep( 1000 );                        } catch (InterruptedException e) {                            e.printStackTrace();                        }                    }                }                Message message = handler.obtainMessage(  );                message.what = 0x01;                handler.sendMessage( message );            }        }.start();    }

 final Handler handler = new Handler(  ){        @Override        public void handleMessage(@NonNull Message msg) {            super.handleMessage( msg );            switch (msg.what){                case 0x00:                    if (msg.arg2 >= 10){                        SignInMinutes.setText( msg.arg2+":" );                }else if (msg.arg2 < 10 && msg.arg2 > 0){                        SignInMinutes.setText( "0"+msg.arg2+":" );                }else {                        SignInMinutes.setText( "00"+":" );                }                    if (msg.arg1 >= 10){                        SignInSeconds.setText( msg.arg1+"" );                    }else if (msg.arg1 < 10 && msg.arg1 > 0){                        SignInSeconds.setText( "0"+msg.arg1 );                    }else {                        SignInSeconds.setText( "00" );                    }                    break;                case 0x01:                    SignInSeconds.setText( "00" );                    SignInMinutes.setText( "00:" );                    break;            }        }    };

二、位置签到

位置签到采用的是百度地图SDK

public class LocationCheckIn extends AppCompatActivity {    private MapView BaiDuMapView;    private TextView CurrentPosition,mLatitude,mLongitude,CurrentDate,SignInPosition;    private Button SubmitMessage,SuccessSignIn;    private ImageView LocationSignIn_Exit;    private  View view = null;    private PopupWindow mPopupWindow;    private LocationClient client;    private BaiduMap mBaiduMap;    private double Latitude = 0;    private double Longitude = 0;    private boolean isFirstLocate = true;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate( savedInstanceState );        if (Build.VERSION.SDK_INT >= 21) {            View decorView = getWindow().getDecorView();            decorView.setSystemUiVisibility( View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE );            getWindow().setStatusBarColor( Color.TRANSPARENT );        }        SDKInitializer.initialize( getApplicationContext() );        client = new LocationClient( getApplicationContext() );//获取全局Context        client.registerLocationListener( new MyBaiDuMap() );//注册一个定位监听器，获取位置信息，回调此定位监听器        setContentView( R.layout.activity_location_check_in );        InitView();        InitBaiDuMap();        InitPermission();        InitPopWindows();        Listener();    }    private void InitView(){        BaiDuMapView = findViewById( R.id.BaiDu_MapView );        CurrentPosition = findViewById( R.id.CurrentPosition );        SubmitMessage = findViewById( R.id.SubmitMessage );        mLatitude = findViewById( R.id.Latitude );        mLongitude = findViewById( R.id.Longitude );        LocationSignIn_Exit = findViewById( R.id.LocationSignIn_Exit );    }    private void InitPopWindows(){         view = LayoutInflater.from( LocationCheckIn.this ).inflate( R.layout.signin_success ,null,false);        CurrentDate = view.findViewById( R.id.CurrentDate );        SignInPosition = view.findViewById( R.id.SignInPosition );        SuccessSignIn = view.findViewById( R.id.Success);        mPopupWindow = new PopupWindow( view, ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT );        mPopupWindow.setFocusable( true ); //获取焦点        mPopupWindow.setBackgroundDrawable( new BitmapDrawable() );        mPopupWindow.setOutsideTouchable( true ); //点击外面地方，取消        mPopupWindow.setTouchable( true ); //允许点击        mPopupWindow.setAnimationStyle( R.style.MyPopupWindow ); //设置动画        Calendar calendar = Calendar.getInstance();        int Hour = calendar.get( Calendar.HOUR_OF_DAY );        int Minute = calendar.get( Calendar.MINUTE );        String sHour,sMinute;        if (Hour < 10){            sHour = "0"+Hour;        }else {            sHour = ""+Hour;        }        if (Minute < 10){            sMinute = "0"+Minute;        }else {            sMinute = ""+Minute;        }        CurrentDate.setText( sHour+":"+sMinute );        //SignInPosition.setText( Position+"000");        SuccessSignIn.setOnClickListener( new View.OnClickListener() {            @Override            public void onClick(View v) {                mPopupWindow.dismiss();            }        } );    }    private void ShowPopWindows(){        mPopupWindow.showAtLocation( view, Gravity.CENTER,0,0 );    }    private void InitBaiDuMap(){        /*百度地图初始化*/        mBaiduMap = BaiDuMapView.getMap();//获取实例，可以对地图进行一系列操作，比如：缩放范围，移动地图        mBaiduMap.setMyLocationEnabled(true);//允许当前设备显示在地图上    }    private void navigateTo(BDLocation location){        if (isFirstLocate){            LatLng lng = new LatLng(location.getLatitude(),location.getLongitude());//指定经纬度            MapStatusUpdate update = MapStatusUpdateFactory.newLatLng(lng);            mBaiduMap.animateMapStatus(update);            update = MapStatusUpdateFactory.zoomTo(16f);//百度地图缩放级别限定在3-19            mBaiduMap.animateMapStatus(update);            isFirstLocate = false;        }        MyLocationData.Builder builder = new MyLocationData.Builder();        builder.latitude(location.getLatitude());//纬度        builder.longitude(location.getLongitude());//经度        MyLocationData locationData = builder.build();        mBaiduMap.setMyLocationData(locationData);    }    private void InitPermission(){        List PermissionList = new ArrayList<>();        //判断权限是否授权        if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.ACCESS_FINE_LOCATION ) != PackageManager.PERMISSION_GRANTED) {            PermissionList.add( Manifest.permission.ACCESS_FINE_LOCATION );        }        if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.READ_PHONE_STATE ) != PackageManager.PERMISSION_GRANTED) {            PermissionList.add( Manifest.permission.READ_PHONE_STATE );        }        if (ContextCompat.checkSelfPermission( LocationCheckIn.this, Manifest.permission.WRITE_EXTERNAL_STORAGE ) != PackageManager.PERMISSION_GRANTED) {            PermissionList.add( Manifest.permission.WRITE_EXTERNAL_STORAGE );        }        if (!PermissionList.isEmpty()) {            String[] Permissions = PermissionList.toArray( new String[PermissionList.size()] );//转化为数组            ActivityCompat.requestPermissions( LocationCheckIn.this, Permissions, 1 );//一次性申请权限        } else {            /*****************如果权限都已经声明，开始配置参数*****************/            requestLocation();        }    }    //执行    private void requestLocation(){        initLocation();        client.start();    }    /*******************初始化百度地图各种参数*******************/    public  void initLocation() {        LocationClientOption option = new LocationClientOption();        option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);        /**可选，设置定位模式，默认高精度LocationMode.Hight_Accuracy：高精度；         * LocationMode.

成绩查询界面

采用的是MD的CardStackView，需要实现一个Adapter适配器，此适配器与RecyclerView适配器构建类似

一、创建StackAdapter 适配器

package com.franzliszt.Student.QueryScore;public class StackAdapter extends com.loopeer.cardstack.StackAdapter {    public StackAdapter(Context context) {        super(context);    }    @Override    public void bindView(Integer data, int position, CardStackView.ViewHolder holder) {        if (holder instanceof ColorItemLargeHeaderViewHolder) {            ColorItemLargeHeaderViewHolder h = (ColorItemLargeHeaderViewHolder) holder;            h.onBind(data, position);        }        if (holder instanceof ColorItemWithNoHeaderViewHolder) {            ColorItemWithNoHeaderViewHolder h = (ColorItemWithNoHeaderViewHolder) holder;            h.onBind(data, position);        }        if (holder instanceof ColorItemViewHolder) {            ColorItemViewHolder h = (ColorItemViewHolder) holder;            h.onBind(data, position);        }    }    @Override    protected CardStackView.ViewHolder onCreateView(ViewGroup parent, int viewType) {        View view;        switch (viewType) {            case R.layout.list_card_item_larger_header:                view = getLayoutInflater().inflate(R.layout.list_card_item_larger_header, parent, false);                return new ColorItemLargeHeaderViewHolder(view);            case R.layout.list_card_item_with_no_header:                view = getLayoutInflater().inflate(R.layout.list_card_item_with_no_header, parent, false);                return new ColorItemWithNoHeaderViewHolder(view);            case R.layout.other_item:                view = getLayoutInflater().inflate(R.layout.other_item, parent, false);                return new ColorItemViewHolder(view);            case R.layout.other_item_thank:                view = getLayoutInflater().inflate(R.layout.other_item_thank, parent, false);                return new ColorItemViewHolder(view);            case R.layout.other_item_note_1:                view = getLayoutInflater().inflate(R.layout.other_item_note_1, parent, false);                return new ColorItemViewHolder(view);

               return new ColorItemViewHolder(view);        }    }    @Override    public int getItemViewType(int position) {        if (position == 6 ){//TODO TEST LARGER ITEM            return R.layout.other_item;

View.VISIBLE : View.GONE);        }        @Override        protected void onAnimationStateChange(int state, boolean willBeSelect) {            super.onAnimationStateChange(state, willBeSelect);            if (state == CardStackView.ANIMATION_STATE_START && willBeSelect) {                onItemExpand(true);            }            if (state == CardStackView.ANIMATION_STATE_END && !willBeSelect) {                onItemExpand(false);            }        }        public void onBind(Integer data, int position) {            mLayout.getBackground().setColorFilter(ContextCompat.getColor(getContext(), data), PorterDuff.Mode.SRC_IN);            mTextTitle.setText( String.valueOf(position));            mTextTitle.setText( "2019-2020第一学期");            itemView.findViewById(R.id.text_view).setOnClickListener(new View.OnClickListener() {                @Override                public void onClick(View v) {                    ((CardStackView)itemView.getParent()).performItemClick(ColorItemLargeHeaderViewHolder.this);                }            });        }    }}

二、绑定适配器

 QueryScoreCardStackView.setItemExpendListener( this );        adapter = new StackAdapter( this );        QueryScoreCardStackView.setAdapter( adapter );

三、为每一个子项添加背景色

public static Integer[] COLOR_DATAS = new Integer[]{            R.color.color_1,            R.color.color_2,            R.color.color_3,            R.color.color_4,            R.color.color_5,            R.color.color_6,            R.color.color_7,            R.color.color_8,            R.color.color_9,            R.color.color_10,    };

 new Handler(  ).postDelayed( new Runnable() {            @Override            public void run() {                adapter.updateData( Arrays.asList( COLOR_DATAS ) );            }        } ,200);
