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:

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);

}

}

}
