觸摸事件不能很好地從孩子調度到父 - 源添加

我有一個線性佈局，其中包含內部（子）自定義圖像視圖。觸摸事件不能很好地從孩子調度到父 - 源添加

我的目標是在圖像視圖上設置背景選擇器，並將線性佈局的偵聽器。

但是，我不能讓選擇器和偵聽器一起工作。我不知道如何處理這些事件。

如果我快速點擊它正在工作，但是如果我在視圖上拖動手指，則圖像視圖將保持選定狀態。

以下是對線性佈局及其偵聽器的引用的活動。

public class EventDispatchingDemoActivity extends Activity 
{ 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     LinearLayout linearLayout = (LinearLayout) findViewById(R.id.my_layout); 

     linearLayout.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) 
      { 
       Toast.makeText(getBaseContext(), "Click", Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 
}

這裏的自定義視圖（ITS我在什麼地方找到一個代碼，筆者學分）

public class ImageSelector extends ImageView 
{ 

    public ImageSelector(Context context, AttributeSet attrs) 
    { 
     super(context, attrs); 
     setBackgroundDrawable(new NavStateListDrawable(getContext(), 0)); 
     setClickable(true); 
    } 

    @Override 
    public boolean onTouchEvent(MotionEvent event) 
    { 
     super.onTouchEvent(event); 
     return false; 
    } 

    public class NavStateListDrawable extends StateListDrawable 
    { 

     private int level; 

     public NavStateListDrawable(Context context, int level) 
     { 

      this.level = level; 
      // int stateChecked = android.R.attr.state_checked; 
      int stateFocused = android.R.attr.state_focused; 
      int statePressed = android.R.attr.state_pressed; 
      int stateSelected = android.R.attr.state_selected; 

      addState(new int[] { stateSelected }, context.getResources().getDrawable(R.drawable.slide_feedback)); 
      addState(new int[] { statePressed }, context.getResources().getDrawable(R.drawable.slide_feedback)); 
      addState(new int[] { stateFocused }, context.getResources().getDrawable(R.drawable.slide_feedback)); 
      addState(new int[] { -stateFocused, -statePressed, -stateSelected }, context.getResources().getDrawable(android.R.color.transparent)); 
     } 

     @Override 
     protected boolean onStateChange(int[] stateSet) 
     { 

      boolean nowstate = super.onStateChange(stateSet); 

      try 
      { 
       LayerDrawable defaultDrawable = (LayerDrawable) this.getCurrent(); 

       LevelListDrawable bar2 = (LevelListDrawable) defaultDrawable.findDrawableByLayerId(R.id.element_contact_image_selector); 
       bar2.setLevel(level); 
      } 
      catch (Exception exception) 
      { 

      } 

      return nowstate; 
     } 
    } 
}

而這裏的XML：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="#acf1fa" 
    android:gravity="center" 
    android:orientation="vertical" > 

    <!-- outer layout --> 

    <LinearLayout 
     android:id="@+id/my_layout" 
     android:layout_width="200dp" 
     android:layout_height="200dp" 
     android:background="#00ff00" 
     android:gravity="center" > 

     <!-- inner layout --> 

     <dor.event.dispathing.ImageSelector 
      android:id="@+id/inner_layout" 
      android:layout_width="150dp" 
      android:layout_height="150dp" /> 
    </LinearLayout> 

</LinearLayout>
