Dismiss Pop up window when back button is pressed

问题

I want to dismiss the pop up window when back button is pressed. I tried with this code: popwindow.setBackgroundDrawable(new BitmapDrawable()); and it works. But in my app, pop should remain, even after touching outside of the pop up window. It should be dismissed only when back button is pressed. So I tried this: popwindow.setFocusable(false); Now its not dismissing when touched outside the pop up. But its not dismissing on back press too. I do not want to overide `onBackPressed(). Is there any other way, through which i can achieve this. Thanks in advance..

回答1:

To disable pop up dismiss when click outside of popwindow set

popwindow.setCanceledOnTouchOutside(false);

and for dismiss it on back button set

popwindow.setCancelable(true);

回答2:

popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);
popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);
new ScaleInAnimation(popupView).animate();
popupWindow.getContentView().setFocusableInTouchMode(true);
popupWindow.getContentView().setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            popupWindow.dismiss();
                return true;
            }
            return false;
        }
    });

Set like this..

    popupWindow.setOutsideTouchable(true); 
    popupWindow.setTouchable(true); 
    popupWindow.setBackgroundDrawable(new BitmapDrawable());           popupWindow.setTouchInterceptor(new OnTouchListener() 
{ 
@Override 
public boolean onTouch(View v, MotionEvent event) 
{ 
if (AppContext.isDebugMode()) 
Log.d("POPUP_WINDOW", "v: "+v.getTag() + " | event: "+event.getAction());
 popupWindow.dismiss(); return true; 
} 
});

Aside from the setOutsideTouchable(true) and setFocusable(true) I had to add

popUpView.setBackgroundDrawable(new BitmapDrawable())

to make it work. This did not change the UI of my popup, but for some magical reason, enabled the back button functionality.

回答5:

The code below may be helpfull:

popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.showAsDropDown(mParent);

And,the show of the popupWindow (popupWindow.showAsDropDown or popupWindow.showAtLocation )must be called in the end.

Set Popup property as..

      popup.setOutsideTouchable(false);
      popup.setCancelable(true);
