Error: View not attached to window manager
提问by jax
I am getting the following remotely from clients so I don't know what hardware etc they are using.
我从客户那里远程获取以下信息，所以我不知道他们正在使用什么硬件等。

This is happening because of a ProgressDialog
这是因为 ProgressDialog
<activity android:theme="@style/GameTheme" android:name=".ActivityGame" android:screenOrientation="portrait" android:launchMode="singleTask" android:configChanges="keyboardHidden|orientation"></activity>
The Activity looks like this in the Manifest.
活动在清单中看起来像这样。
if (pDialog.isShowing()) {
pDialog.cancel();
}
So what could this mean? I think it has something to do with the Activity being destroyed then created but as you can see I have the configChanges set correctly.
那么这意味着什么呢？我认为这与 Activity 被销毁然后创建有关，但正如您所看到的，我的 configChanges 设置正确。

Try:
尝试：
public void onDestroy(){
super.onDestroy();
if(progressDialog!=null)
if(progressDialog.isShowing()){
progressDialog.cancel();
}
}
in your overridden onDestroy()or onStop()methods.
在您的重写onDestroy()或onStop()方法中。

This problem arises when trying to show a dialog after you've exited an Activity.
在退出Activity.
I just solved this problem just by writing down the following code:
我只是通过写下以下代码解决了这个问题：
if (pDialog.getWindowToken() != null)
{
pDialog.dismiss();
}
Basically, from which class you started progressDialog, override onDestroy()method and do this way. It solved Activity has leaked windowproblem.
基本上，从哪个类开始progressDialog，覆盖onDestroy()方法并这样做。它解决了Activity 已泄漏窗口问题。

It usually happens when you call dismiss after activity has been closed.
它通常发生在您在活动关闭后调用关闭时。

In order to handle invisible views, you cannot use isShowing() and should check for the window attachment itself in your onDestroy()
为了处理不可见的视图，您不能使用 isShowing() 并且应该在 onDestroy() 中检查窗口附件本身
if (test_service_overlay != null) {
if (test_service_overlay.getWindowToken() != null) {
WindowManager windowManager = (WindowManager) getBaseContext().getSystemService(Context.WINDOW_SERVICE);
windowManager.removeViewImmediate(test_service_overlay);
}
}
or in my case, I was not using a dialog but a custom window added by the WindowManager, which was (possibly) invisible.
或者就我而言，我没有使用对话框，而是使用 WindowManager 添加的自定义窗口，该窗口（可能）不可见。
if(pDialog.isShowing())
{
try
{
pDialog.dismiss();
}
catch(Exception e) {// nothing }
}

Im also faced the same problem when I tried to dismiss the dialog at onPageFinished method of Web view. sometimes onPageFinished called after the activity has been closed.
当我尝试在 Web 视图的 onPageFinished 方法中关闭对话框时，我也遇到了同样的问题。有时在活动关闭后调用 onPageFinished。
Here is the solution for it:
这是它的解决方案：
##代码##Try it!
尝试一下！

You can ask "dialog.isIndeterminate()" as well. Works fine.
您也可以询问“dialog.isIndeterminate()”。工作正常。
