Question

这是我的代码：

        LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LinearLayout viewGroup = (LinearLayout) findViewById(R.id.layout_popup);
        final View layout = layoutInflater.inflate(R.layout.popup_layout,viewGroup);

        final PopupWindow popup = new PopupWindow(GameActivity.this);

        Point popupSize = new Point(getResources().getDimensionPixelSize(R.dimen.popup_width),getResources().getDimensionPixelSize(R.dimen.popup_height));


        popup.setContentView(layout);
        popup.setWidth(popupSize.x);
        popup.setHeight(popupSize.y);
        popup.setFocusable(true);

        File dir = getFilesDir();
        File temp = new File(dir.getPath()+"/temp.prj");
        try {
            if(!temp.exists())temp.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }

        File[] filesArray = dir.listFiles();
        ArrayList<String> files = new ArrayList<>();

        for(File file:filesArray)
        {
            files.add(file.getName());
        }

        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);

        popup.showAtLocation(layout, Gravity.NO_GRAVITY, (size.x-popupSize.x)/2, (size.y-popupSize.y)/2);


        ListView listView = (ListView)layout.findViewById(R.id.listViewDir);
        final EditText fileName = (EditText)layout.findViewById(R.id.editTextFilename);

        final StableArrayAdapter adapter = new StableArrayAdapter(GameActivity.this,R.layout.list_item, files);

        listView.setAdapter(adapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, final View view, int position, long id) {
                final TextView item = (TextView) view;
                fileName.setText(item.getText());
            }
        });

导致我麻烦的是：

            @Override
            public void onItemClick(AdapterView<?> parent, final View view, int position, long id) {
                final TextView item = (TextView) view;
                fileName.setText(item.getText());
            }

在我点击列表视图中的项目之后，然后我点击文件名视图和例外

 android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@53668b30 is not valid; is your activity running?

被抛出。我尝试在UI线程上运行fileName.setText(item.getText());，我尝试在许多不同的地方使用MainActivity.this（或我的变体，GameActivity.this）。似乎没有什么工作。有谁知道出了什么问题？所有相关问题似乎都围绕着Dialog而不是Popup

更新

出于某种原因，将android:inputType="textNoSuggestions"添加到xml中的EditText fileName会停止异常。在列表视图中的项目前面添加一个数字（这意味着它们不会被拼写检查）之后我才注意到这一点。看起来其他人遇到了类似的错误Android ICS spelling error correction causes PopupWindow to crash而且他们也没有答案

android.view.WindowManager $ BadTokenException列表视图设置文本然后焦点
