Android Click Click PopupWindow

Question

我創建了一個擴展popupwindow的類。它的構造看起來像下面

super(builder.context.get()); 

this.setWindowLayoutMode(ViewGroup.LayoutParams.MATCH_PARENT, 
     ViewGroup.LayoutParams.MATCH_PARENT); 
setFocusable(true); 
setBackgroundDrawable(new BitmapDrawable()); 
setTouchInterceptor(onTouchListener); 
FrameLayout frameLayout = new FrameLayout(builder.context.get()); 
LayoutInflater inflater = (LayoutInflater) builder.context.get().getSystemService(
     Context.LAYOUT_INFLATER_SERVICE); 
View overlayBase = inflater.inflate(R.layout.tutorial_view_items, null, false); 
frameLayout.addView(builder.backgroundView); 
frameLayout.addView(overlayBase); 
setContentView(frameLayout); 

的onTouchListener如下所示：

private OnTouchListener onTouchListener = new OnTouchListener() { 
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
     float x = event.getX(); 
     float y = event.getY(); 
     Log.d(TAG, "Received"); 

     if (Math.pow(x - coordinates[0], 2) + Math.pow((y - coordinates[1]), 2) < Math.pow(radius, 2)) { 
      Log.d(TAG, "bubbled through"); 
      return false; 
     } 
     return true; 
    } 
}; 

實際顯示popupwindow，我叫SomePopupWindow.showAtLocation(SomeActivity.getWindow().getDecorView().getRootView(), Gravity.CENTER, 0, 0);

可視表示，這裏是有問題的產品

touchListener正在響應，但輸入不會被髮送到基礎活動或彈出窗口？ （該按鈕沒有響應，就好像我要刪除ontouchlistener一樣，按鈕工作正常）。

更新 設置觸摸偵聽到的FrameLayout（在這種情況下，即popupwindow的內容視圖），而不是popupwindow本身允許我點擊在彈出定義的按鈕。還在尋找方法來觸摸事件委託給底層活動/圖

SOLUTION

註冊爲Popupwindow觸摸攔截。如果您希望該活動處理該活動，則假設您有該活動的參考，請撥打someActivity.dispatchTouchEvent(someMotionEventPassedIntoTheTouchIntercepter);，如果您希望該彈出窗口處理該觸摸，請撥打someView.dispatchTouchEvent(theMotionEventPassedToTouchInterceptor)至彈出窗口的內容視圖，如在彈出窗口setContentView(someView)方法中設置的。

我的方法具體看起來像下面

private OnTouchListener onTouchListener = new OnTouchListener() { 
@Override 
    public boolean onTouch(View v, MotionEvent event) { 
     float x = event.getX(); 
     float y = event.getY(); 

     if (Math.pow(x - coordinates[0], 2) + Math.pow((y - coordinates[1]), 2) < Math.pow(
       radius, 2)) { 
      activity.get().dispatchTouchEvent(event); 
      return false; 
     } 
     frameLayout.dispatchTouchEvent(event); 
     return true; 
    } 
};

public class TestPopupActivity extends Activity { 

//The "x" and "y" position of the "Show Button" on screen. 
Point p; 

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

    Button btn_show = (Button) findViewById(R.id.show_popup); 
    btn_show.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View arg0) { 

     //Open popup window 
     if (p != null) 
     showPopup(TestPopupActivity.this, p); 
    } 
    }); 
} 

// Get the x and y position after the button is draw on screen 
// (It's important to note that we can't get the position in the onCreate(), 
// because at that stage most probably the view isn't drawn yet, so it will return (0, 0)) 
@Override 
public void onWindowFocusChanged(boolean hasFocus) { 

    int[] location = new int[2]; 
    Button button = (Button) findViewById(R.id.show_popup); 

    // Get the x, y location and store it in the location[] array 
    // location[0] = x, location[1] = y. 
    button.getLocationOnScreen(location); 

    //Initialize the Point with x, and y positions 
    p = new Point(); 
    p.x = location[0]; 
    p.y = location[1]; 
} 

// The method that displays the popup. 
private void showPopup(final Activity context, Point p) { 
    int popupWidth = 200; 
    int popupHeight = 150; 

    // Inflate the popup_layout.xml 
    LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popup); 
    LayoutInflater layoutInflater = (LayoutInflater) context 
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    View layout = layoutInflater.inflate(R.layout.popup_layout, viewGroup); 

    // Creating the PopupWindow 
    final PopupWindow popup = new PopupWindow(context); 
    popup.setContentView(layout); 
    popup.setWidth(popupWidth); 
    popup.setHeight(popupHeight); 
    popup.setFocusable(true); 

    // Some offset to align the popup a bit to the right, and a bit down, relative to button's position. 
    int OFFSET_X = 30; 
    int OFFSET_Y = 30; 

    // Clear the default translucent background 
    popup.setBackgroundDrawable(new BitmapDrawable()); 

    // Displaying the popup at the specified location, + offsets. 
    popup.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y); 

    // Getting a reference to Close button, and close the popup when clicked. 
    Button close = (Button) layout.findViewById(R.id.close); 
    close.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     popup.dismiss(); 
    } 
    }); 
} 
}
