如何按下第一个按钮，释放第二个按钮并获得第二个按钮的触摸事件？

Question

我有2个按钮。这是我在做什么：

1. 我按下按钮1
2. 然后，我将我的手指扣2
3. 我按钮2

我设置触摸释放2个按钮的听众。它记录的触摸事件的两个按钮：

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     Button button1 = (Button) findViewById(R.id.button1); 
     Button button2 = (Button) findViewById(R.id.button2); 

     button1.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        Log.d("ButtonTouchTag", "Button 1: DOWN"); 
       } else if (event.getAction() == MotionEvent.ACTION_MOVE) { 
        Log.d("ButtonTouchTag", "Button 1: MOVE"); 
       } else if (event.getAction() == MotionEvent.ACTION_UP) { 
        Log.d("ButtonTouchTag", "Button 1: UP"); 
       } 

       return true; 
      } 
     }); 

     button2.setOnTouchListener(new View.OnTouchListener() 

     { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        Log.d("ButtonTouchTag", "Button 2: DOWN"); 
       } else if (event.getAction() == MotionEvent.ACTION_MOVE) { 
        Log.d("ButtonTouchTag", "Button 2: MOVE"); 
       } else if (event.getAction() == MotionEvent.ACTION_UP) { 
        Log.d("ButtonTouchTag", "Button 2: UP"); 
       } 
       return false; 
      } 
     }); 

    } 

} 

此代码记录下列信息：

• 按钮1：DOWN
• 按钮1：MOVE
• 按钮1：MOVE
• 。按钮1：移动
• 按钮1：移动
• 按钮1：UP

正如你所看到的，按钮2没有得到触摸事件。

问题：如何按下第一个按钮，释放第二个按钮并获得第二个按钮上的触摸事件？

Answer 1

button2.setOnTouchListener(new View.OnTouchListener() 

     { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        Log.d("ButtonTouchTag", "Button 2: DOWN"); 
       } else if (event.getAction() == MotionEvent.ACTION_MOVE) { 
        Log.d("ButtonTouchTag", "Button 2: MOVE"); 
       } else if (event.getAction() == MotionEvent.ACTION_UP) { 
        Log.d("ButtonTouchTag", "Button 2: UP"); 
       } 
       return true; 
      } 
     }); 

它应该返回true。
