Answer 1

这很有可能发生,因为您正在尝试在执行后台线程后显示一个对话框,而Activity正在被销毁.

当我试图显示对话时,当调用对话框的活动由于某种原因而完成时,我看到我的一些应用程序偶尔会报告此错误.这是为我解决的问题:

if(!((Activity) context).isFinishing())
{
    //show dialog
}

我已经使用它来解决旧版本Android上的问题已经好几年了,并且从那时起就没有看到崩溃.

Answer 2

我遇到了同样的问题,并使用上面DiscDev提出的代码进行了如下的微小更改:

if (!MainActivity.this.isFinishing()){
    alertDialog.show();
}

Answer 3

如果对话框因为线程而出现这个问题，你应该像这样在 UI 线程上运行它：-

runOnUiThread(new Runnable() {
            @Override
            public void run() {
                dialog.show();

            }
        });

Answer 4

当您显示不再存在的上下文的对话框时，会发生此错误。

在调用之前.show()检查活动/上下文是否未完成

if (!(context instanceof Activity && ((Activity) context).isFinishing())) {
    alert.show();
}
