Question

我正在尝试将一个整数值从一个Activity发送到一个Broadcast接收器，这是我的Activity中的方法代码：

public void vibrator(View view){
    if (((ToggleButton) view).isChecked()) {

        Toast.makeText(getApplicationContext(), "Vibration ON",
                Toast.LENGTH_LONG).show();

        Intent intent = new Intent(AddAlarm.this, AlarmReceiver.class);
        intent.putExtra("vibrator",1);

    }
}

现在，从广播接收器，当我尝试调用时：

Intent receive = getIntent();

这是一个错误，但如何以正确的方式执行此操作？

AlarmReceiver中的代码：

public class AlarmReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(final Context context, Intent intent) {
    int vibrator = intent.getIntExtra("vibrator", 1);

    PendingIntent sender = PendingIntent.getBroadcast(context, 0, 
intent, 0);


    Uri alarmUri = 
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
    if (alarmUri == null)
    {
        alarmUri = 
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    }
    Ringtone ringtone = RingtoneManager.getRingtone(context, alarmUri);
    ringtone.play();


    //intent to call the activity which shows on ringing
    Intent myIntent = new Intent(context, Time_Date.class);
    myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(myIntent);

    //display that alarm is ringing
    Toast.makeText(context, "Alarm Ringing...!!!", 
Toast.LENGTH_LONG).show();

    ComponentName comp = new ComponentName(context.getPackageName(),
            AlarmService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);

    if(vibrator==1)
    {
        Log.w("the value I get is","given as"+vibrator);

    }


}

}

从广播接收器调用getIntent（）时出错

getIntent()方法不是来自BroadcastReceiver类。

在BroadcastReceiver中获取使用sendBroadcast方法发送的意图使用onReceive方法第二个参数Intent：

 @Override
   public void onReceive(Context context, Intent intent) {
       int vibrator=intent.getIntExtra("vibrator",1);
   }

从广播接收器
