当前回答

只需确保您的活动不会由于代码中某处引发的异常而意外关闭。通常在异步任务中，当activity在doinBackground方法中面临强制关闭时，asynctask返回到onPostexecute方法。

其他回答

最好的解决方案是在try catch中添加对话框，并在异常发生时解散对话框

只需使用下面的代码

 try {
        dialog.show();
    } catch (Exception e) {
        dialog.dismiss();
    }

在活动销毁前解散progressBar

@Override
    protected void onDestroy() {
        try {
            if (progressDialog != null)
                progressDialog.dismiss();
        } catch (Exception e) {
            e.printStackTrace();
        }
        super.onDestroy();
    }

这不是问题的答案，但与主题相关。

如果活动在清单中定义了属性

 android:noHistory="true"

然后在执行onPause()后，活动的上下文将丢失。所有使用这个context的视图都会给出这个错误。

试试下面的代码:

public class Sample extends Activity(){
@Override
 public void onCreate(Bundle instance){

}
 @Override
    public void onStop() {
        super.onStop();
      progressdialog.dismiss(); // try this
    }

}

您试图在退出活动后显示一个对话框。

(编辑)

这个问题是谷歌上android开发者搜索最多的问题之一，因此，从评论中添加一些重要的观点，这可能对未来的调查人员更有帮助，而不需要深入评论对话。

答案1:

您试图在退出活动后显示一个对话框。

回答2

在某些情况下，这个错误可能会有点误导(尽管答案仍然是完全准确的)-即在我的情况下，一个在AsyncTask中抛出了unhandled异常，这导致活动关闭，然后一个打开的progressdialog导致了这一点异常. .所以'real'异常在日志中稍早一些

回答3

在退出前创建的Dialog实例上调用dismiss() 活动，例如在onPause()或onDestroy()中
