android – PopupMenu PopupWindow $PopupViewContainer泄漏

2019-10-06 13:31:06 阅读：339 来源： 互联网

我有一个PopupMenu锚定到Action Bar中的一个按钮,我正在获取有关泄漏窗口的日志输出.

如果在PopupMenu打开时我的活动停止,则会发生这种情况.

我发布了一个相关问题here,但我已经解决了这个问题.

我见过一些类似的问题,比如this,但没有一个与PopupMenu有关.

我想我是否可以在提到的PopupWindow $PopupViewContainer上获得一个句柄,然后我可以在onPause或类似的东西中从WindowManager中删除它,但我不知道如何得到它. PopupMenu公开的界面非常有限.

这就是我创建菜单的方法：

// 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();

        }
    });

这是完整的堆栈跟踪：

解决方法:

简单地调用profileMenu.dismiss()onStop()就足够了.
