PopupWindow-在某些设备上不起作用 [英] PopupWindow - not working on a few devices

问题描述

我使用以下代码显示一个小的弹出窗口:

I use following code to show a small popup:

public static PopupWindow showImportMenu(Activity activity, View anchor, PopupWindowClickListener onClickListener)
{
    LayoutInflater inflater = LayoutInflater.from(activity);

    PopupImportBinding binding = DataBindingUtil.inflate(inflater, R.layout.popup_import, null, false);

    if (!RootTools.isRootAvailable())
        binding.llImportRootMethod.setVisibility(View.GONE);


    PopupWindow popupWindow = new PopupWindow(activity, null, R.attr.popupMenuStyle);
    popupWindow.setFocusable(true);
    popupWindow.setContentView(binding.getRoot());
    popupWindow.setOutsideTouchable(true);
    PopupWindowCompat.showAsDropDown(popupWindow, anchor, 0, 0, Gravity.BOTTOM);

    View.OnClickListener clickListener = new View.OnClickListener()
    {
        @Override
        public void onClick(View view)
        {
            onClickListener.onClick(popupWindow, view);
        }
    };

    binding.llImportDefault.setOnClickListener(clickListener);
    binding.llImportRootMethod.setOnClickListener(clickListener);
    binding.llImportHTCFromContacts.setOnClickListener(clickListener);
    binding.llImportManual.setOnClickListener(clickListener);

    return popupWindow;
}

此功能可在许多设备上使用，但在某些稀有设备上则无法使用，例如:

This works on a lot of devices but on some rare devices it does not work, like:

• Android 5.1.1 root slim rom
• 也许是其他人...直到现在，我对其他设备一无所知

我得到的反馈是没有显示弹出窗口.有谁知道为什么在上面提到的设备上不起作用?我该怎么做才能使其在该设备上正常工作?

I got the feedback that no popup is shown. Does anyone know why this is not working on the above mentioned device? And what I can do to make it work on this device as well?

编辑

似乎不清楚我想要的是什么

It seems like it's not clear that what I want is following:

• 使用showAsDropDown而不是showAtLocation或类似的字体，我还没见过showAtLocation出现此问题
• 我的解决方案几乎可以在所有设备上运行，这似乎是特定于电话/ROM的问题，也许甚至无法解决，因为它也可能是设备中的错误=>如果有人知道这样的错误，告诉我也很好
• 我不想使用对话框(或其他任何对话框)，这没有回答我的问题.我目前使用的BottomSheet对我来说很好，但是我仍然想知道问题是否可以解决并以某种方式解决

• use showAsDropDown not showAtLocation or similar, I never saw this problem with showAtLocation yet
• my solution is working on nearly all devices, it seems to be a phone/rom specific problem, maybe it's not even solvable as it COULD be a bug in the device as well => if someone knows of such a bug, telling me would be fine as well
• I don't want to use a dialog (or anything else) instead, that's not answering my question. I currently use a BottomSheet which is fine for me, but still I would like to know if the problem can be solved and somehow handled

推荐答案

在运行5.1.1的Nexus 7(不是2012)上，我遇到了同样的问题.最后通过添加以下行对其进行了修复:

I got the same problem on a Nexus 7 (not 2012) running the 5.1.1. It is finally fixed by adding this line:

popupWindow.setWindowLayoutMode(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
