本文实例为大家分享了Alarmmanager实现简单闹钟功能的具体代码，供大家参考，具体内容如下

代码：

activity_main.xml

MainActivity.java

packagecom.example.haige.alarmmanager;

importandroid.app.Activity;
importandroid.app.AlarmManager;
importandroid.app.PendingIntent;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.view.View;
publicclassMainActivityextendsActivity
{
protectedvoidonCreate(BundlesavedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

/*
启动闹钟
*/
publicvoidstartAlarmClick(Viewview)
{
//获取系统的闹钟服务
AlarmManageram=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
//触发闹钟的时间（毫秒）
longtriggerTime=System.currentTimeMillis()+3000;
Intentintent=newIntent(this,Alarmctivity.class);
PendingIntentop=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
//启动一次只会执行一次的闹钟
am.set(AlarmManager.RTC,triggerTime,op);
////指定时间重复执行闹钟
//am.setRepeating(AlarmManager.RTC,triggerTime,2000,op);
}

/*
设置闹钟
*/
publicvoidstartSetAlarmClick(Viewview)
{
//获取系统的闹钟服务
AlarmManageram=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
//触发闹钟的时间（毫秒）
longtriggerTime=System.currentTimeMillis()+3000;
Intentintent=newIntent(this,AlarmReceiver.class);
PendingIntentop=PendingIntent.getBroadcast(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
//启动一次只会执行一次的闹钟
am.set(AlarmManager.RTC,triggerTime,op);
////指定时间重复执行闹钟
//am.setRepeating(AlarmManager.RTC,triggerTime,2000,op);
}
}

activity_alarmctivity.xml

Alarmctivity.java

packagecom.example.haige.alarmmanager;

importandroid.app.Activity;
importandroid.app.AlarmManager;
importandroid.app.AlertDialog;
importandroid.app.PendingIntent;
importandroid.content.Context;
importandroid.content.DialogInterface;
importandroid.content.Intent;
importandroid.media.MediaPlayer;
importandroid.net.Uri;
importandroid.os.Bundle;
importjava.io.IOException;

publicclassAlarmctivityextendsActivity
{
MediaPlayermp;
protectedvoidonCreate(BundlesavedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alarmctivity);
mp=newMediaPlayer();
try{
mp.setDataSource(this,Uri.parse("/storage/sdcard1/kugou/听力/南拳妈妈-你不像她.mp3"));
mp.prepare();
}catch(IOExceptione){
e.printStackTrace();
}
mp.setLooping(true);
mp.start();
alarmOialog();
}


@Override
protectedvoidonResume(){
super.onResume();
}

@Override
protectedvoidonDestroy(){
super.onDestroy();
if(mp!=null)
{
if(mp.isPlaying())
{
mp.stop();
}
mp.release();
}
}

publicvoidalarmOialog(){
AlertDialog.Builderbuilder=newAlertDialog.Builder(this);
builder.setMessage("大哥，大妹子喊你起床啦！");
builder.setPositiveButton("再来一次",newDialogInterface.OnClickListener(){

@Override
publicvoidonClick(DialogInterfacedialogInterface,inti){
alarm();
finish();
}
});

builder.setNegativeButton("停止",newDialogInterface.OnClickListener(){

@Override
publicvoidonClick(DialogInterfacedialogInterface,inti){
finish();//关闭窗口
}
});
builder.show();
}

privatevoidalarm(){
//获取系统的闹钟服务
AlarmManageram=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
//触发闹钟的时间（毫秒）
longtriggerTime=System.currentTimeMillis()+5000;
Intentintent=newIntent(this,Alarmctivity.class);
PendingIntentop=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
//启动一次只会执行一次的闹钟
am.set(AlarmManager.RTC,triggerTime,op);
//指定时间重复执行闹钟
//am.setRepeating(AlarmManager.RTC,triggerTime,2000,op);
}

}

广播接收器AlarmReceiver.java

packagecom.example.haige.alarmmanager;

importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.widget.Toast;

publicclassAlarmReceiverextendsBroadcastReceiver{
publicAlarmReceiver(){
}

@Override
publicvoidonReceive(Contextcontext,Intentintent){
Toast.makeText(context,"起床啦，起床啦！",Toast.LENGTH_SHORT).show();
}
}
