如何將onTouch設置爲通過通貨膨脹添加的佈局（XML）？

Question

我試圖讓控制按鈕在屏幕被點擊時彈出開/關屏幕。他們將覆蓋視頻。我遇到的問題是如何爲已膨脹的佈局創建觸摸事件。
例程如下：
1）將初始內容設置爲視頻;
2）在視頻頂部打開包含控件的佈局（XML）;
3）（需要做）爲用戶點擊屏幕時隱藏/顯示按鈕的新膨脹佈局創建onTouch事件。

包含的按鈕佈局顯示/隱藏：

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       android:id="@+id/dpad_grid" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:columnCount="3" 
       android:orientation="horizontal" 
       android:layout_alignParentBottom="true" 
       android:layout_centerHorizontal="true"> 

     <Button 
      android:id="@+id/tiltUp" 
      android:background="@drawable/arrow_up" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginBottom="5dp" 
      android:layout_row="0" 
      android:layout_column="1"/> 

     <Button

      android:layout_marginRight="5dp" 
      android:layout_row="1" 
      android:layout_column="0"/> 

    </GridLayout> 

    <Button 
     android:id="@+id/zoomIn" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="15dp"

    <Button

     android:layout_height="wrap_content" 
     android:background="@drawable/zoom_out" 
     android:layout_marginRight="0dp" 
     android:layout_alignParentBottom="true" 
     android:layout_toStartOf="@+id/zoomIn"/> 

    <Button 
     android:id="@+id/irisDarker" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginRight="8dp" 
     android:layout_alignParentBottom="true"

     android:background="@drawable/iris_darker"/> 

    <Button

     android:layout_alignParentBottom="true" 
     android:layout_toEndOf="@+id/irisDarker" 
     android:background="@drawable/iris_brighter"/> 

    <Button 
     android:id="@+id/focusFar" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignTop="@+id/dpad_grid" 
     android:layout_marginRight="20dp"

     android:background="@drawable/focus_far"/> 

    <Button

    <Button

     android:background="@drawable/camera" 
     android:layout_alignEnd="@+id/focusFar" 
     android:layout_alignParentStart="true"/> 

    <Button 
     android:id="@+id/settings" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:background="@drawable/gear"/> 

</RelativeLayout> 

代碼添加視頻和充氣上述佈局：

@Override 
    public void onResume() { 
     super.onResume();  

     RelativeLayout.LayoutParams relativeLayoutParams = 
       new RelativeLayout.LayoutParams(
         RelativeLayout.LayoutParams.WRAP_CONTENT, 
         RelativeLayout.LayoutParams.WRAP_CONTENT); 

     mv = new MjpegView(this); 
     setContentView(mv); 

     LayoutInflater inflater = getLayoutInflater(); 
     getWindow().addContentView(inflater.inflate(R.layout.screen2, null), relativeLayoutParams); 

感謝您的幫助！

編輯：這是我目前的工作。當我觸摸屏幕時，爲什麼我的代碼不能進入觸摸事件？

LayoutInflater inflater = getLayoutInflater(); 
     control_buttons = inflater.inflate(R.layout.screen2, null); 

     control_buttons.setOnTouchListener(new View.OnTouchListener() { 
      boolean gone = true; 

      @Override 
      public boolean onTouch(View v, MotionEvent event) { 

       System.out.println("In OnTouch"); 

       if ((event.getAction() == MotionEvent.ACTION_DOWN) && (gone == true)){ 

        getWindow().addContentView(control_buttons, relativeLayoutParams); 

        gone = false; 
        return true; 
       } 

       else if ((event.getAction() == MotionEvent.ACTION_DOWN) && (gone == false)) { 
        v.setVisibility(View.GONE); 
        gone = true; 
        return true; 
       } 
       return false; 
      } 
     });

這可能對您更好。這隻有在您的RelativeLayout中的子項是包含按鈕的按鈕或GridLayouts時纔有效。

RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.yourId); 
    relativeLayout.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      if(event.getAction() == MotionEvent.ACTION_DOWN) { 
       for(int i = 0; i < relativeLayout.getChildCount(); i++) { 
        if(relativeLayout.getChildAt(i) instanceof Button) { 
         Button temp = (Button) relativeLayout.getChildAt(i); 
         if(temp.getVisibility() == View.INVISIBLE) { 
          temp.setVisibility(View.VISIBLE); 
         } else { 
          temp.setVisibility(View.INVISIBLE); 
         } 
        } else if(relativeLayout.getChildAt(i) instanceof GridLayout) { 
         GridLayout temp = (GridLayout) relativeLayout.getChildAt(i); 
         for(int g = 0; g < temp.getChildCount(); g++) { 
          Button tempButton = (Button) temp.getChildAt(g); 
          if(tempButton.getVisibility() == View.INVISIBLE) { 
           tempButton.setVisibility(View.VISIBLE); 
          } else { 
           temp.setVisibility(View.INVISIBLE); 
          } 
         } 
        } 
       } 
      } 

      return false; 
     } 
    });
