窗口泄漏异常通常是由未正确关闭的对话框引起的。即，如果您打算在 asynctask 的 Onpostexecute 中关闭一个对话框并且创建它的活动已经结束，它将引发窗口泄漏。确保在活动的 onPause 中关闭对话框。

每当您启动 ProgressDialog 时，应该在后台任务完成后正确关闭，甚至取消后台运行任务。所以，

而不是mProgressBar.hide();使用mProgressBar.dismiss();

你不会得到 android.view.WindowLeaked 错误

希望这可以帮助

检查您是否在 mDialog.show() 函数之前使用了 finish() 函数。如果是删除 finish() 并在 show() 之后添加它。

当您错过此代码时：mProgressDialog.dismis();那时您可能会收到此类错误。

在onStop()或onDestroy()回调中，使用关闭对话框dialogName.dismiss();

还要进行空检查。那是：

if (dialogName != null) {
    dialogName.dismiss();
}

发生此错误的另一种情况是应用程序在显示对话框时崩溃。查看此错误上方的其他错误。

问题是AsyncTask。

new AsyncTask<Void, Void, String>() {

    CustomDialog mProgressBar = new CustomDialog(MobileConnectActivity.this, R.style.dialog);
    .... 
}

您在异步任务中创建了一个进度条，当您移动到另一个活动时会出现问题。

为此，在解雇或 show() 之前

if(!isFinishing() && dialog != null) { dialog.dismiss();}

isFinishing()的用法

 * Check to see whether this activity is in the process of finishing,
 * either because you called {@link #finish} on it or someone else
 * has requested that it finished.  This is often used in
 * {@link #onPause} to determine whether the activity is simply pausing or
 * completely finishing.
 *
 * @return If the activity is finishing, returns true; else returns false.

对我来说问题正在发生，因为我使用了android:noHistory="true"导致问题的活动，并且它只发生在 Android 6.0 API 23 上。

简单地关闭对话框并不足以消除我的错误。事实证明，即使在对话框被解除后，我的代码仍保留对对话框的引用。对我来说，关键是在关闭对话框后将该引用设置为 null。
