PopupMenu PopupWindow$PopupViewContainer leak

2019-02-12 16:43发布

问题:

I have a PopupMenu anchored to a button in the Action Bar, and I'm getting log output about a leaked window.

This occurs if my activity is stopped while the PopupMenu is open.

I posted a related question here, but I've solved that issue.

I've seen some similar questions, like this, but none related to PopupMenu.

I'm thinking if I can get a handle on the mentioned PopupWindow$PopupViewContainer then I could remove it from the WindowManager during onPause or something like that, but I don't know how to get at it. The interface exposed by PopupMenu is pretty limited.

  • Has anyone encountered this issue?
  • Has anyone fixed it or worked around it?
  • Anybody know how to get the PopupMenu's View or Window?

This is how I create the menu:

// in Activity
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    final MenuInflater inflater = getMenuInflater();

    inflater.inflate(R.menu.main_menu, menu);
    MenuItem login = menu.findItem(R.id.menu_login);
    final Button button = (Button) login.getActionView().findViewById(R.id.login);

    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View item) {
            if (profileMenu == null) {
                // I've tried passing getApplicationContext() here too, with no change
                profileMenu = new PopupMenu(ListActivity.this, button);
                profileMenu.getMenuInflater().inflate(R.menu.profile_menu, profileMenu.getMenu());
                profileMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {
                        // there was code here, but I removed it and problem persists
                        return false;
                    }
                });
            }
            profileMenu.show();

        }
    });

Simply calling profileMenu.dismiss() onStop() would be enough.
