安卓 AlarmManager 不工作

Question

我在论坛上搜索过，但它对其他人有用。我的 AlarmManager 有什么问题？我想每分钟调用一次CallDataSend类

public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent alarmIntent = new Intent(this, CallDataSend.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
            alarmIntent, PendingIntent.FLAG_ONE_SHOT);

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (2 * 1000), pendingIntent);
    Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show();
   }
}

CallDataSend 类:

public final class CallDataSend extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();

}
}

和xml文件:

<receiver
        android:name="CallDataSend"
        android:enabled="false">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"></action>
        </intent-filter>
     </receiver>

我认为您应该先启用接收器，然后系统才能对其进行实例化。

<receiver
        android:name="CallDataSend"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"></action>
        </intent-filter>
     </receiver>
