当我拖下图像时，按钮不起作用

Question

在我的xml按钮上，我想声明图像，当我拖动图像时，按钮单击不起作用，它在背景中，它确实来了forground。

怎么可能使用按钮？当我点击按钮时，我想要显示烤面包片。

public class MainActivity extends Activity { 
    /** Called when the activity is first created. */ 
    ImageView img = null; 
    AbsoluteLayout aLayout; 
    int status = 0; 
    int Measuredwidth = 0, MeasuredHeight = 0; 
    float x = 0; 
    boolean first = true; 
    Bitmap icon; 
    Button b; 

    @SuppressLint("NewApi") 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     aLayout = (AbsoluteLayout) findViewById(R.id.absLayout); 

     img = (ImageView) findViewById(R.id.imageView); 
     icon = BitmapFactory.decodeResource(getResources(), R.drawable.gg); 

     b = (Button) findViewById(R.id.btnFavorites); 
     Point size = new Point(); 
     WindowManager w = getWindowManager(); 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) { 
      w.getDefaultDisplay().getSize(size); 
      MeasuredHeight = size.y; 
      Measuredwidth = size.x; 
     } else { 
      Display d = w.getDefaultDisplay(); 
      Measuredwidth = d.getWidth(); 
      MeasuredHeight = d.getHeight(); 
     } 

     b.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       b.setVisibility(View.GONE); 
       Toast.makeText(MainActivity.this, "activity closed", 
         Toast.LENGTH_LONG).show(); 

      } 
     }); 

     aLayout.setOnTouchListener(new OnTouchListener() { 

      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       // TODO Auto-generated method stub 
       if (event.getAction() == MotionEvent.ACTION_UP) { 
        status = 0; 

        // img.setBackgroundColor(Color.TRANSPARENT); 

       } else if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        if (first) { 
         x = event.getX(); 
         first = false; 
        } 
       } else if (event.getAction() == MotionEvent.ACTION_MOVE) { 
        // 
       } 
       if ((event.getX() < (Measuredwidth - icon.getWidth()/2) && event 
         .getX() > (icon.getWidth()/2)) 
         && (event.getY() < MeasuredHeight 
           - (icon.getHeight() + 60) && event.getY() > icon 
           .getHeight()/2)) { 
        @SuppressWarnings("deprecation") 
        // (int) event.getX()-img.getWidth()/2 
        LayoutParams lp = new AbsoluteLayout.LayoutParams(
          LayoutParams.WRAP_CONTENT, 
          LayoutParams.WRAP_CONTENT, (int) 0, (int) event 
            .getY() - img.getHeight()/2); 
        img.setLayoutParams(lp); 
       } 

       return true; 
      } 
     }); 

    } 

}

如果你把上的按钮图像，按钮就会失去控制的话，你可以使用背景或绘制的左侧或右侧顶部底部给绘制（图像）按钮......或者否则，你可以在我给drawableleft代码上点击听众甚至在图像视图.. 更新实现..

<Button 
    android:id="@+id/btnFavorites" 
    android:layout_width="match_parent" 
    android:layout_height="45dip" 
    android:drawablePadding="10dp" 
    android:paddingLeft="10dp" 
    android:layout_marginTop="1dip" 
    android:gravity="left|center_vertical" 
    android:background="#242D41" 
    android:drawableLeft="@drawable/favorite_slide" 
    android:includeFontPadding="false" 
    android:text="@string/titleFavourites" 
    android:textColor="#ffffff" 
    android:textSize="15dip" 
    android:textStyle="bold" /> 

，同样哟可以给正确的左上角，甚至填充也可以，并应用您的逻辑触摸
