Question

友

onCreate（）我正在使用Async线程从webservice加载数据。当线程启动时，它会在屏幕上显示进度条并加载数据。

我遇到的一个突然问题是，当我开始显示活动进度条时，我改变了手机第二线程开始的方向＆amp;

应用程序崩溃。（Inovation Target Exception就是这样）。

这是log cat任何人指导我这个问题的解决方案是什么？

代码很简单

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.searchbanks);
    threadBank = new AsyncBanks();
    threadBank.execute("","");
}

Answer 1

即使您关闭对话框以便可以重新创建它，系统在销毁对话框和生命周期方法之间似乎存在竞争条件，您可以将其解除。我很少收到关于在配置更改时解除不存在的对话框的崩溃报告。

我建议捕获并忽略Dialog.dismiss（）中的异常只是为了处理竞争条件。这就是我所做的，它解决了我的问题。
