android - PopupMenu PopupWindow$PopupViewContainer 泄漏

Question

我有一个 PopupMenu 锚定到操作栏中的一个按钮，并且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 Activity 停止，就会发生这种情况。

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 , 但与 PopupMenu 无关。

我在想，如果我可以处理提到的 PopupWindow$PopupViewContainer，那么我可以在 onPause 或类似的过程中将其从 WindowManager 中删除，但我不知道如何得到它。 PopupMenu 公开的接口(interface)非常有限。

• 有人遇到过这个问题吗？
• 是否有人修复或解决了它？
• 有人知道如何获取PopupMenu 的View 或Window 吗？

这是我创建菜单的方式:

// 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:

Answer 1

只需调用 profileMenu.dismiss() onStop() 就足够了。
