public class MsgAdapter extends ArrayAdapter{  private int resourceID;  public MsgAdapter(Context context, int resource, List objects) {  super(context, resource, objects);  resourceID = resource; }  @Override public View getView(int position, View convertView, ViewGroup parent) {  Msg msg = getItem(position);  View view;  ViewHolder viewHolder;  if(convertView == null) {   view = LayoutInflater.from(getContext()).inflate(resourceID,  null);   viewHolder = new ViewHolder();   viewHolder.leftLayout = (LinearLayout)view.findViewById(R.id.left_layout);   viewHolder.rightLayout = (LinearLayout) view.findViewById(R.id.right_layout);   viewHolder.leftMsg = (TextView) view.findViewById(R.id.left_msg);   viewHolder.rightMsg = (TextView) view.findViewById(R.id.right_msg);   view.setTag(viewHolder);  }else {   view = convertView;   viewHolder = (ViewHolder) view.getTag();  }  if(msg.getType() == Msg.MSG_RECEIVE) {   viewHolder.leftLayout.setVisibility(View.VISIBLE);   viewHolder.rightLayout.setVisibility(View.GONE);   viewHolder.leftMsg.setText(msg.getMessage());  }else {   viewHolder.rightLayout.setVisibility(View.VISIBLE);   viewHolder.leftLayout.setVisibility(View.GONE);   viewHolder.rightMsg.setText(msg.getMessage());  }  return view; }  class ViewHolder {  LinearLayout leftLayout;    LinearLayout rightLayout;    TextView leftMsg;    TextView rightMsg;   } }

public class Msg { public static final int MSG_RECEIVE = 0; public static final int MSG_SEND = 1;  private int type; private String content;  public Msg(String content, int type) {  this.content = content;  this.type = type; }  public String getMessage() {  return content; } public int getType() {  return type; }}

3.ListView单个view布局

4.ListView加载Adapter

public class MainActivity extends Activity {  private ListView listView;  private MsgAdapter msgAdapter;  private List msgList = new ArrayList();  private EditText input;  private Button send;  @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_main);  listView = (ListView) findViewById(R.id.msg_list_view);  initMsg();  msgAdapter  = new MsgAdapter(this, R.layout.msg_item, msgList);  listView.setAdapter(msgAdapter);    input = (EditText) findViewById(R.id.input_text);  send = (Button) findViewById(R.id.send);  send.setOnClickListener(new OnClickListener() {      @Override   public void onClick(View v) {    String message = input.getText().toString();    if(!"".equals(message)) {     Msg msg = new Msg(message, Msg.MSG_SEND);     msgList.add(msg);     msgAdapter.notifyDataSetChanged();//当有新消息时刷新     listView.setSelection(msgList.size());    }else {     Toast.makeText(MainActivity.this, "input can"t be empty", Toast.LENGTH_SHORT).show();    }    input.setText("");   }  }); }  private void initMsg() {  Msg msg;  msg = new Msg("Hi, boy", Msg.MSG_RECEIVE);  msgList.add(msg);  msg = new Msg("Hi, girl", Msg.MSG_SEND);  msgList.add(msg);  msg = new Msg("what"s up", Msg.MSG_RECEIVE);  msgList.add(msg); }}
