android - 内存/线程相关的方向更改崩溃？

Question

friend ，

onCreate() 我正在使用异步线程从网络服务加载数据。当线程启动时，它会在屏幕上显示进度条并加载数据。

我突然遇到的问题是，当我开始显示 Activity 进度条时，我改变了手机的方向，第二个线程开始了 &

应用程序崩溃。(Inovation Target Exception 之类的)。

这是日志猫，谁能指导我解决这个问题的方法是什么？

代码简单

@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重新创建它，在销毁对话框的系统和您将关闭它的生命周期方法之间似乎存在竞争条件。我很少收到关于在配置更改时关闭不存在的对话框的崩溃报告。

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