原理：
请求系统发送一个广播，在本程序接收该广播，并做一系列的操作，属于跨进程的开发
1、点击控件请求系统发送广播
public void doClick(View v) {
switch (v.getId()) {
case R.id.btn_notification:
sendNotification();// 发送通知
break;
}
2、在通知栏需要显示的通知样式
/**
* 自定义
*/
private void sendNotificationZidinyi() {
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Builder builder = new Builder(MainActivity.this);
RemoteViews views = new RemoteViews(getPackageName(), R.layout.notification_zidinyi);
//给RemoteViews添加点击意图
Intent activityIntent = new Intent(MainActivity.this,MainActivity.class);
PendingIntent pi5 = PendingIntent.getActivity(MainActivity.this, 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.btn_startActivity, pi5);
//给播放按钮添加点击意图
Intent broadIntent = new Intent("ACTION_SEND_BROADCAST");
PendingIntent broadCastPi = PendingIntent.getBroadcast(MainActivity.this, 0, broadIntent , Context.BIND_DEBUG_UNBIND);
views.setOnClickPendingIntent(R.id.img_player, broadCastPi);
builder.setContentTitle("")
.setTicker("自定义")
.setSmallIcon(R.drawable.small_pic)
.setContent(views )
;
Notification notifi = builder.build();
manager.notify(555,notifi);
}
3、动态注册广播接收者
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
receiver = new PlayerBroadcastReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction("ACTION_SEND_BROADCAST");
registerReceiver(receiver, filter);
}
4、写一个清除通知的方法，在其生命周期结束时自行清除
private void clearNotification() {
// 单例系统服务，可重复创建
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(NOTIFI_MANAGER_ID);
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
isDoing=false;
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(588);
unregisterReceiver(receiver);
super.onDestroy();
}
