android - 从 Activity A 调用方法到 Activity B 时出错

Question

我想在收到短信时增加进度条的进度(在两个模拟器上测试)，但出现错误 - 出乎意料，强制关闭。

这是我在 Activity 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 Activity SMReceiver:

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？

Answer 1

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

你犯的错误是

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