当我收到一条短信（在两个模拟器上测试）时，我想增加进度条的进度，但我收到了一个错误 - 意外地，强制关闭。

这是我在活动 A 中的代码：

progressBar = (ProgressBar)findViewById(R.id.progresslevel);
  new Thread(new Runnable() {
    public void run() {
      // TODO Auto-generated method stub
      while (progressStatus < 50000) {
        mHandler.post(new Runnable() {
          public void run() {
            // TODO Auto-generated method stub
            progressBar.setProgress(progressStatus);
          }
        });
      }
  }).start();

Activity A中的增加方法：

public static void increaseValue(Boolean isSMS) {
  if (isSMS == true) {
    progressStatus += 5000;
  } else {
    progressStatus += 7000;
  }
}

我的活动短信接收器：

public class SMSReceive extends BroadcastReceiver {
  @Override
    public void onReceive(Context context, Intent intent) {
      // TODO Auto-generated method stub
      FloCareActivity.increaseValue(true);
    }
}

如何解决？

这意味着你的清单告诉 android 你有一个名为 的类nth.flocare.demo.SMSReceiver，而 Android 找不到它。

您所做的错误是

您有代码中的类名SMSReceive，Android 正在尝试查找nth.flocare.demo.SMSReceiver因此将您的类重命名为SMSReceiver

Thread您的代码在您创建的一个紧密循环中尽可能快地将 new Runnables 发布到事件循环中。Handler您没有发布足够的代码或堆栈跟踪来让我们查看这是否是唯一的问题，但它肯定是需要修复的问题。仅在进度值更改时发布消息。当然，不需要单独的线程来执行此操作。这是一个非常快速的操作。额外的线程应该只用于防止 UI 线程被长操作延迟。
