Close Android popup window with back press

Question

I have created a android application where I have created a popup screen. But when I am pressing the back button, popup is not getting closed.

I have tried with onB

Answer 1

//here "popUp" is ref of PopupWindow

popUp.setBackgroundDrawable(new BitmapDrawable());// it is most important peace of code

// For Key Listeners

View v = popUp.getContentView();

//Here assigning the key Listners

    v.setOnKeyListener(this);

    @Override   
    public boolean onKey(View v, int keyCode, KeyEvent event) {

        if(keyCode == KeyEvent.KEYCODE_BACK) popUp.dismiss();

        return false;

    }//Implements the KeyListener
     //and be careful we should implement "OnKeyListener"`

I hope it is useful (I'm the new user)

Answer 2

100% popup will dismiss on back press. Replace your Popup code with this below code

public void popup() {

    View popUpView_pur = getActivity().getLayoutInflater().inflate(R.layout.popup, null);
    PopupWindow popuplayout_pur = new PopupWindow(popUpView_pur, -1, -1, true);
    popuplayout_pur.setBackgroundDrawable(new BitmapDrawable());
    popuplayout_pur.setOutsideTouchable(true);
    popuplayout_pur.showAtLocation(popUpView_pur, 17, 0, 0);

}

(or)

public void popup() {
    // TODO Auto-generated method stub
    LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View popupView = inflater.inflate(R.layout.popuplayout, null, false);

    PopupWindow pw = new PopupWindow(getActivity());
    pw.setWidth(WindowManager.LayoutParams.MATCH_PARENT);
    pw.setHeight(WindowManager.LayoutParams.MATCH_PARENT);

    pw.setTouchable(true);
    pw.setFocusable(true);
    pw.setOutsideTouchable(true);
    pw.setContentView(popupView);

    pw.showAtLocation(popupView, Gravity.CENTER, 0, 0);
}
