一 、先来配置自定义控件需要的资源

1.在res文件夹下创建一个anim文件夹并创建两个slide_in_bottom.xml、slide_out_bottom.xml文件，负责弹框进出动画。

2.在style.xml添加阴影和动画样式。

3.在drawable文件夹下创建一个title_background.xml文件，负责给文本内容添加背景。

二、自定义控件的布局

三、自定义控件类

public class ButtomDialog extends Dialog {   public ButtomDialog(Context context, int themeResId) {    super(context, themeResId);  }   public static class Params {    private final List menuList = new ArrayList<>();    private View.OnClickListener cancelListener;    private CharSequence menuTitle;    private String cancelText;    private Context context;  }   public static class Builder {    private boolean canCancel = true;    private boolean shadow = true;    private final Params p;     public Builder(Context context) {      p = new Params();      p.context = context;    }     public Builder setCanCancel(boolean canCancel) {      this.canCancel = canCancel;      return this;    }     public Builder setShadow(boolean shadow) {      this.shadow = shadow;      return this;    }     public Builder setTitle(CharSequence title) {      this.p.menuTitle = title;      return this;    }     public Builder addMenu(String text, View.OnClickListener listener) {      BottomMenu bm = new BottomMenu(text, listener);      this.p.menuList.add(bm);      return this;    }     public Builder addMenu(int textId, View.OnClickListener listener) {      return addMenu(p.context.getString(textId), listener);    }     public Builder setCancelListener(View.OnClickListener cancelListener) {      p.cancelListener = cancelListener;      return this;    }     public Builder setCancelText(int resId) {      p.cancelText = p.context.getString(resId);      return this;    }     public Builder setCancelText(String text) {      p.cancelText = text;      return this;    }     public ButtomDialog create() {      final ButtomDialog dialog = new ButtomDialog(p.context, shadow ? R.style.Theme_Light_NoTitle_Dialog : R.style.Theme_Light_NoTitle_NoShadow_Dialog);      Window window = dialog.getWindow();      window.setWindowAnimations(R.style.Animation_Bottom_Rising);      window.getDecorView().setPadding(0, 0, 0, 0);      WindowManager.LayoutParams lp = window.getAttributes();      lp.width = WindowManager.LayoutParams.MATCH_PARENT;      lp.height = WindowManager.LayoutParams.WRAP_CONTENT;      window.setAttributes(lp);      window.setGravity(Gravity.BOTTOM);      View view = LayoutInflater.from(p.context).inflate(R.layout.dialog_bottom_menu, null);      TextView btnCancel = (TextView) view.findViewById(R.id.btn_cancel);      ViewGroup layContainer = (ViewGroup) view.findViewById(R.id.lay_container);      ViewGroup.LayoutParams lpItem = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);      ViewGroup.MarginLayoutParams lpDivider = new ViewGroup.MarginLayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 1);      lpDivider.setMargins(50,0,50,0);      int dip1 = (int) (1 * p.context.getResources().getDisplayMetrics().density + 0.5f);      int spacing = dip1 * 12;      boolean hasTitle = !TextUtils.isEmpty(p.menuTitle);      if (hasTitle) {        //标题样式        TextView tTitle = new TextView(p.context);        tTitle.setLayoutParams(lpItem);        tTitle.setGravity(Gravity.CENTER);        tTitle.setTextColor(p.context.getResources().getColor(R.color.colorAccent));        tTitle.setText(p.menuTitle);        tTitle.setPadding(0, spacing, 0, spacing);        //单独给标题设置背景样式//        tTitle.setBackgroundResource(R.drawable.common_dialog_selection_selector_top);        layContainer.addView(tTitle);        View viewDivider = new View(p.context);        viewDivider.setLayoutParams(lpDivider);        viewDivider.setBackgroundColor(0xFFCED2D6);        layContainer.addView(viewDivider);      }      //每一条的样式      for (int i = 0; i < p.menuList.size(); i++) {        BottomMenu bottomMenu = p.menuList.get(i);        TextView bbm = new TextView(p.context);        bbm.setLayoutParams(lpItem);        bbm.setPadding(0, spacing, 0, spacing);        bbm.setGravity(Gravity.CENTER);        bbm.setText(bottomMenu.funName);        bbm.setTextColor(0xFF007AFF);        bbm.setTextSize(16);        bbm.setOnClickListener(bottomMenu.listener);        layContainer.addView(bbm);        if (i != p.menuList.size() - 1) {          View viewDivider = new View(p.context);          viewDivider.setLayoutParams(lpDivider);          viewDivider.setBackgroundColor(0xFFCED2D6);          layContainer.addView(viewDivider);        }      }       if (!TextUtils.isEmpty(p.cancelText)) {        btnCancel.setText(p.cancelText);      }       if (p.cancelListener != null) {        btnCancel.setOnClickListener(p.cancelListener);      } else {        btnCancel.setOnClickListener(new View.OnClickListener() {          @Override          public void onClick(View v) {            dialog.dismiss();          }        });      }       dialog.setContentView(view);      dialog.setCanceledOnTouchOutside(canCancel);      dialog.setCancelable(canCancel);      return dialog;    }   }   private static class BottomMenu {    public String funName;    public View.OnClickListener listener;     public BottomMenu(String funName, View.OnClickListener listener) {      this.funName = funName;      this.listener = listener;    }  }}

四、使用

public class MainActivity extends AppCompatActivity implements View.OnClickListener {   private Button mDialogCustom;  private ButtomMenuDialog dialog;   @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    initView();  }   private void initView() {    mDialogCustom = (Button) findViewById(R.id.custom_dialog);    mDialogCustom.setOnClickListener(this);  }   @Override  public void onClick(View v) {    switch (v.getId()) {      case R.id.custom_dialog:        ButtomMenuDialog.Builder builder = new ButtomMenuDialog.Builder(this);        //添加条目，可多个        builder.addMenu("相机", new View.OnClickListener() {          @Override          public void onClick(View view) {            dialog.cancel();            Toast.makeText(MainActivity.this, "相机", Toast.LENGTH_SHORT).show();          }        }).addMenu("相册", new View.OnClickListener() {          @Override          public void onClick(View view) {            dialog.cancel();            Toast.makeText(MainActivity.this, "相册", Toast.LENGTH_SHORT).show();          }        });        //下面这些设置都可不写        builder.setTitle("这是标题");//添加标题        builder.setCanCancel(false);//点击阴影时是否取消dialog，true为取消        builder.setShadow(true);//是否设置阴影背景，true为有阴影        builder.setCancelText("取消");//设置最下面取消的文本内容        //设置点击取消时的事件        builder.setCancelListener(new View.OnClickListener() {          @Override          public void onClick(View view) {            dialog.cancel();            Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();          }        });        dialog = builder.create();        dialog.show();        break;      default:        break;    }  }}
