Answer 1

LayoutInflater layoutInflater = (LayoutInflater)MainActivity.this.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.popup_window_country_list, null);
    countryPopup = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    countryPopup.setBackgroundDrawable (new BitmapDrawable());

    countryPopup.setFocusable(true); //Make Here True For back press dismiss

    countryPopup.setOutsideTouchable(true); 

    countryPopup.setTouchInterceptor(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {

                countryPopup.dismiss();


                return true;

            }

            return false;

        }
    });

The popup window normally closes when you press the back button. if you need to handle certain things when the popup closes, you can use

popupWindow.setOnDismissListener

Note:- I worked in kotlin. It worked for me

Answer 3

popup.setBackgroundDrawable(new BitmapDrawable());

popup.setOnDismissListener(new PopupWindow.OnDismissListener() {
            @Override
            public void onDismiss() {
                //do your code here
            }
        });

What you need to do is call setBackgroundDrawable on your PopupWindow after you initialize it. Something like:

myPopup.setBackgroundDrawable(new BitmapDrawable());

Answer 5

Following code is working perfectly. So override following function in your activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
     //Changes 'back' button action
    if(keyCode==KeyEvent.KEYCODE_BACK)
    {
        if(!popUpHelper.isPopupShowing()){
            onBackPressed();
        }else{
            popUpHelper.dismiss();
        }
    }

    return super.onKeyDown(keyCode, event);
}


class PopupHelper {
 PopupWindow popupWindowAttachment;
  public void initAndShow(Activity context,int mToolbarHeight){

   View layout = activity.getLayoutInflater().inflate(
            R.layout.activity_chat_attachment_popup, null);
    //create and show and Make sure popup window focusable should be false
    popupWindowAttachment = new PopupWindow(layout,
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    popupWindowAttachment.showAsDropDown(layout, 0, mToolbarHeight
            + (mToolbarHeight / 2) - 5);

  }

  public void dismiss() {
    if (isPopupShowing())
            popupWindowAttachment.dismiss();
  }
  public boolean isPopupShowing() {
    return popupWindowAttachment==null?false:popupWindowAttachment  
                 .isShowing();
  }
}

Recently I worked with ListPopupWindow (android.support.v7.internal.widget.ListPopupWindow) and back button started to work when I called

popupWindow.setModal(true);

no matter what I set in setBackgroundDrawable method as other solutions suppose here.
