Question

I’m having a very frustrating problem with PopupWindow on Android.
I’ve implemented my own class that inherits PopupWindow and implements
OnClickListener.

After adding button backgrounds with custom selectors problems start.
This background keeps disappearing after clicking the button (starting new activity and dismissing the popup).
It doesn’t disappear after “focus and click“, only after “quick click“.

Any idea/suggestion would be very appriciated!

public class TestPopup extends PopupWindow implements OnClickListener

protected LayoutInflater inflater;
protected Activity caller;
protected View popup;
protected View layout;

public TestPopup(Activity activity) {
    super(activity);
    popup = inflater.inflate(R.layout.popup, (ViewGroup) caller.findViewById(R.id.contentLayout));
    layout = popup.findViewById(R.id.layout);

    popup.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

    Display display = caller.getWindowManager().getDefaultDisplay();
    setHeight(display.getHeight());
    setWidth(display.getWidth());
    setFocusable(true);
    setContentView(popup);

    // fix to allow Popup to be clickable!
    setBackgroundDrawable(new BitmapDrawable());

    popup.setOnClickListener(this);
    popup.findViewById(R.id.addButton).setOnClickListener(this);
    popup.findViewById(R.id.deleteButton).setOnClickListener(this);
}

public void onClick(View v) {
    Intent intent = null;
    if (v.getId() == R.id.addButton) {
        intent = new Intent(caller, AddActivity.class);
        intent.putExtra(AddActivity.ACTION_ADD, true);
    } else if (v.getId() == R.id.deleteButton) {
        intent = new Intent(caller, AddActivity.class);
        intent.putExtra(AddActivity.ACTION_DELETE, true);
    }

    if (intent != null) {
        caller.startActivity(intent);
    }

    TestPopup.this.dismiss();
}

One solution is to call popup.invalidate(); before dismissing the popup.
