Answer 1

窗口泄露的异常通常是由对话框引起的,这些对话框没有被正确解雇.即如果你打算在asynteask的Onpostexecute中删除一个对话框,并且创建它的活动已经结束,它将抛出一个窗口泄漏.确保在活动的onPause中显示dimisss对话框.

Answer 2

每当你启动ProgressDialog时,应该在后台任务完成后正确解除,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

Answer 3

检查mDialog.show()函数之前是否使用了finish()函数.如果是删除finish()并在show()之后添加它.

Answer 4

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

Answer 5

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。在此错误上方查看其他错误。

Answer 6

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();
}
