Android将触摸事件从一个画廊传递到另一个画廊

Question

我有两个不同大小的相对布局的画廊。后面的画廊比上面的画廊小，所以我希望画廊后面的触摸事件作出反应，如果两个画廊的公共部分被触摸，否则上面的画廊应该反应。目前只有上面的画廊正在反应。你有什么想法如何实现这一点？

我没有尝试，但是这可以帮助你：

覆盖onTouchEvent在gallary1，然后复制MotionEvent并将它传递给其他GALLARY让它命名为gallary1

@Override 
    public boolean onTouchEvent(MotionEvent event) { 

     MotionEvent event2=MotionEvent.obtain(event); 
     gallery2.onTouchEvent(event2); 

     return super.onTouchEvent(event); 
    }

全码（它的工作）：

public class MyGallary extends Gallery { 

    public MyGallary(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
    } 

public MyGallary(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    } 

public MyGallary(Context context) { 
    super(context); 
    } 

    private MyTouchListener myTouchListener; 

    @Override 
    public boolean onTouchEvent(MotionEvent event) { 
     if (myTouchListener != null) { 
      myTouchListener.onTouch(event); 
     } 
     return super.onTouchEvent(event); 
    } 

    public MyTouchListener getMyTouchListener() { 
     return myTouchListener; 
    } 

    public void setMyTouchListener(MyTouchListener myTouchListener) { 
     this.myTouchListener = myTouchListener; 
    } 

}

public interface MyTouchListener { 

    public void onTouch(MotionEvent event); 

}

public class MainActivity extends Activity { 

    MyGallary gallary1; 
    Gallery gallary2; 
    MyTouchListener listener1; 

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

     gallary1 = (MyGallary) findViewById(R.id.myGallary1); 
     listener1 = new MyTouchListener() { 

      @Override 
      public void onTouch(MotionEvent event) { 
       MotionEvent event2 = MotionEvent.obtain(event); 
       gallary2.onTouchEvent(event2); 

      } 
     }; 
     gallary1.setMyTouchListener(listener1); 

     gallary2 = (Gallary) findViewById(R.id.Gallary2); 

     int[] array = new int[] { R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher, 
       R.drawable.ic_launcher, R.drawable.ic_launcher }; 

     ImageAdapter adapter1 = new ImageAdapter(array); 
     gallary1.setAdapter(adapter1); 

     ImageAdapter adapter2=new ImageAdapter(array); 
     gallary2.setAdapter(adapter2); 

    } 

    class ImageAdapter extends BaseAdapter { 

     int[] array; 

     public ImageAdapter(int[] array) { 
      this.array = array; 
     } 

     @Override 
     public int getCount() { 
      return array.length; 
     } 

     @Override 
     public Object getItem(int position) { 

      return array[position]; 
     } 

     @Override 
     public long getItemId(int position) { 
      return position; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 

      if (convertView == null) { 
       ImageView imageView = new ImageView(MainActivity.this); 
       Gallery.LayoutParams params = new Gallery.LayoutParams(
         Gallery.LayoutParams.MATCH_PARENT, 
         Gallery.LayoutParams.MATCH_PARENT); 

       imageView.setLayoutParams(params); 

       convertView = imageView; 

      } 

      ImageView imageView = (ImageView) convertView; 
      imageView.setImageResource((Integer) getItem(position)); 

      return convertView; 
     } 
    }
