And when set PopupWindow.setFocusable to the true, the EditText is focused and activity go to sleep! Other item on the pop up window works, but back button on the phone and clicking outside the pop up does not close it. Thanks in advance.

Some code from my project may help

        LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        PopupWindow  share_popup = new PopupWindow(inflater.inflate(R.layout.share_dropdown, null, false), 162, LinearLayout.LayoutParams.WRAP_CONTENT, true);
        share_popup.setOutsideTouchable(true);
        share_popup.setTouchable(true);
        share_popup.setFocusable(true);
        Drawable image_saved = getResources().getDrawable(R.drawable.dummy_bg);
        share_popup.setBackgroundDrawable(image_saved);

where this R.drawable.dummy_bg is a transparent image.
