如何实现android 警报管理器?
回答:
从服务设置警报:
package yourPackage;import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
public class YourService extends Service
{
Alarm alarm = new Alarm();
public void onCreate()
{
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
alarm.setAlarm(this);
return START_STICKY;
}
@Override
public void onStart(Intent intent, int startId)
{
alarm.setAlarm(this);
}
@Override
public IBinder onBind(Intent intent)
{
return null;
}
}
如果要设置在电话启动时重复发出警报:
向Manifest.xml
添加权限和服务:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>...
<receiver android:name=".AutoStart">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
...
<service
android:name=".YourService"
android:enabled="true"
android:process=":your_service" >
</service>
并创建一个新类:
package yourPackage;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AutoStart extends BroadcastReceiver
{
Alarm alarm = new Alarm();
@Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED))
{
alarm.setAlarm(context);
}
}
}
