新建一个class 继承BroadcastReceiver，并实现onReceive()方法。当BroadcastReceiver接收到广播后，就会去执行OnReceive()方法。所以，我们在OnReceive()方法中加上代码，当接收到广播后就跳到显示提醒信息的Activity。具体代码如下( MyReceiver.java)：
package com.Reminder;
import android.content.BroadcastReceiver;import android.content.Context;
import android.content.Intent;
/**
* Receive the broadcast and start the activity that will show the alarm
*/
public class MyReceiver extends BroadcastReceiver {
/**
* called when the BroadcastReceiver is receiving an Intent broadcast.
*/
@Override
public void onReceive(Context context, Intent intent) {
/* start another activity - MyAlarm to display the alarm */
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setClass(context, MyAlarm.class);
context.startActivity(intent);
}
}
注意：创建完BroadcastReceiver后，需要在AndroidManifest.xml中注册：
<receiver android:name=".MyReceiver">
