6--AlarmManager实例

定制闹铃：

public class AlarmActivity extends Activity {

private static final String TAG="AlarmActivity";

private Button setBtn,cancleBtn;

private int requestCode = 100;

private AlarmManager alarmManager ;

private PendingIntent operation;//声明定义

private Calendar calendar;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(https://www.360docs.net/doc/ed8882350.html,yout.activity_alarm);

setBtn = (Button)findViewById(R.id.setAlarmbtn);

cancleBtn = (Button)findViewById(R.id.cancleAlarmbtn);

//得到AlarmManager：获取全局定时器的服务管理器

alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

long triggerAtTime = System.currentTimeMillis();

Intent intent = new Intent();

intent.setAction("com.bawei.alarm.broadcast");

operation = PendingIntent.getBroadcast(this, requestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);

calendar = Calendar.getInstance();

calendar.setTimeInMillis(System.currentTimeMillis());

setBtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

int hour = calendar.get(Calendar.HOUR_OF_DAY);

int minute = calendar.get(Calendar.MINUTE);

//TimePickerDialog方法有五个参数，第一个参数（MenuView.this）为弹出的时间对话框所在的activity指针；

//第二个参数:设置时间

//第三个参数（hour）和第四个参数（minute）为弹出的时间对话框的初始显示的小时和分钟，这两个变量在蓝色代码中进行初始化；

//第五个参数为设置24时显示参数，true代表时间以24时制显示时间。

TimePickerDialog dialog = new TimePickerDialog(AlarmActivity.this, new OnTimeSetListener() {

@Override

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

// TODO Auto-generated method stub

Log.d(TAG, ""+hourOfDay +":"+minute);

calendar.setTimeInMillis(System.currentTimeMillis());//把调整后的时间设置上

calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);

calendar.set(Calendar.MINUTE, minute);

calendar.set(Calendar.SECOND, 0);

long triggerAtTime = calendar.getTimeInMillis();

/**

* 指定的任务只会执行一次，如果该pendingIntent指定的任务已经被执行过了，那么该方法直接会被cancel掉。

* set(int type, long triggerAtTime, PendingIntent operation)

* type 指定定时模式。

* triggerAtTime 触发任务的时间。该参数和定时模式息息相关

* operation 该参数指定一个广播Intent，当时间到了时，系统会广播里面的intent，触发相应的广播接收者执行某些操作，比如响铃……

*/

alarmManager.set(AlarmManager.RTC_WAKEUP, triggerAtTime, operation);//安排一个任务

//alarmManager.setRepeating(type, triggerAtTime, interval, operation);

}

}, hour, minute, true);

dialog.show();

}

});

cancleBtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

alarmManager.cancel(operation);

}

});

}

}

到点广播接收：

public class AlarmBroadcastReceiver extends BroadcastReceiver {

private static final String TAG="AlarmBroadcastReceiver";

private Context context ;

MediaPlayerService.MyBinder myBinder;

MediaPlayer mediaPlayer;

Intent in;

@Override

public void onReceive(final Context context, Intent intent) {

// TODO Auto-generated method stub

Log.d(TAG, "onReceiver......");

this.context = context;

/*NotificationManager noManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = new Notification();

notification.icon = R.drawable.ic_launcher;

notification.tickerText="Notification TickerText";

//notification.flags = notification.DEFAULT_SOUND;

notification.audioStreamType=android.media.AudioManager.ADJUST_LOWER;

notification.sound=Uri.parse("file:///sdcard/shoot1.ogg");

notification.flags = notification.FLAG_AUTO_CANCEL;//自动取消

Intent intent1 = new Intent(context,AlarmActivity.class);

PendingIntent contentIntent = PendingIntent.getActivity(context, 111, intent1, 0);

notification.setLatestEventInfo(context, "content Title", "content Text", contentIntent);

noManager.notify(1, notification);*/

in = new Intent();

in.setAction("com.bawei.alarm.musicservice");

context.startService(in);

AlertDialog alertDialog = null;

AlertDialog.Builder builder = new AlertDialog.Builder(context.getApplicationContext());

builder.setTitle("闹铃来了");

builder.setMessage("起床？");

builder.setPositiveButton("确定",new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

context.stopService(in);

dialog.cancel();

}

});

builder.setNegativeButton("取消",new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

dialog.cancel();

}

});

alertDialog = builder.create();

alertDialog.getWindow().setType(https://www.360docs.net/doc/ed8882350.html,youtParams.TYPE_SYSTEM_ALERT);//设置系统级别的对话框

alertDialog.show();

}

}

在广播中启动服务：

public class MusicTest1 extends Service {

MediaPlayer mp;

@Override

public IBinder onBind(Intent intent) {

// TODO Auto-generated method stub

return null;

}

@Override

public void onCreate() {

// TODO Auto-generated method stub

super.onCreate();

Uri uri = Uri.parse("sdcard/music/u.mp3");

mp=MediaPlayer.create(this, uri);

mp.start();

}

@Override

public void onDestroy() {

// TODO Auto-generated method stub

super.onDestroy();

mp.stop();

}

}

广播中启动Activity：

public class MySystemOpen extends BroadcastReceiver{

@Override

public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub

//跳转到一个Activity上

Intent in = new Intent();

// 在新的任务中启动Activity

in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

// 设置Intent启动的组件名称

in.setClass(context,MainActivity.class);

context.startActivity(in);

}

}
