threadid = 9：线程退出时出现未捕获的异常（group = 0x40015560）

我在执行我的android应用程序时遇到强制关闭问题。当我试图根据从服务器收到的响应代码进行“Toast”时，我正面临强制关闭错误。即使发送消息没有问题，因为消息每次都能正确传送。显示吐司时发生错误。我正在粘贴所有代码和日志消息。请帮我整理出了错误threadid = 9：线程退出时出现未捕获的异常（group = 0x40015560）

你想在UI线程内显示烤面包吗？ –

我昨天告诉过你，你这样做都是错误的，但你没有听... – LuxuryMode

@LuxuryMode：而不是告诉他错误的电话他出错了:) mi8帮助别人：P :) –

You cannot call a Toast from that thread.您需要在UI线程上运行代码。这是为了避开它最简单的方法：

this.runOnUiThread(new Runnable() { 
    public void run() { 
     Toast.makeText(MainActivity.this, "SMS Sending Failed.", 
      Toast.LENGTH_SHORT).show(); 

    } 
});

而且这段代码的意思是，我的解决this question是正确的？如果是的话请remember to select the correct answer，如果没有请在解决该问题之前询问涉及相同代码的单独问题。

编辑：另外，你正在得到一个异常，这是调用这个吐司消息的原因是因为你发送响应代码之前，你存储它。只有第一次拨打readLine()才会返回响应码。在第一个问题你发送到System.out.println()什么也没做。现在您将它发送到您的日志，以便您能够看到它，但之后它就消失了。你需要将它存储在您登录之前：

responsecode = br.readLine(); 
Log.d("SmsResponse", responsecode);

当我们要不能在主UI线程与其他UI操作的上背上沉重的任务或耗时的任务会举行

解决一个问题是什么意思？ –

我的意思是你应该一次只处理一个问题，因为那么当有人过来回答你的问题时，它可能不再有效，因为你已经改变了代码来回应另一个问题。 – Fr33dan

我使用此代码，但仍然是相同的错误。 'this.runOnUiThread（new Runnable（）{} {public void run（）{ Toast.makeText（MainActivity.this，“SMS Sending Failed。”， Toast.LENGTH_SHORT）。显示（）; } }）; ' –

线程的使用和它会给你和错误。

因此，做这样耗时的任务，如Makking网络连接或下载任何文件，我们需要线程。

但吐司是一个UI元素，它只会在主UI线程上执行。
