PopupMenu PopupWindow $ PopupViewContainer泄漏 [英] PopupMenu PopupWindow$PopupViewContainer leak

问题描述

我有一个PopupMenu固定在操作栏中的按钮上，并且我正在获取有关泄漏窗口的日志输出.

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

如果在打开PopupMenu时我的活动停止了，就会发生这种情况.

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

我在此处发布了一个相关问题，但我已经解决了该问题.

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

我已经看到了一些类似的问题，例如这，但都没有与PopupMenu相关的问题.

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

我正在考虑是否可以处理上述PopupWindow$PopupViewContainer的句柄，然后可以在onPause或类似的过程中将其从WindowManager中删除，但我不知道该怎么做. PopupMenu公开的界面非常有限.

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.

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

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

这是我创建菜单的方式:

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();

        }
    });

这是完整的堆栈跟踪:

推荐答案

仅在onStop()上调用profileMenu.dismiss()就足够了.

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