在自定义通知中执行按钮单击操作:Android [英] Perform Action On Button Click in Custom Notification : Android
问题描述
我正在尝试执行一些操作,例如暂停音乐,在 android 中单击自定义通知按钮播放音乐.目前我正在这样做,
I am trying to perform some action like pause music , play music on button click of a custom notification in android. Currently I am doing it in this way ,
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, "Custom Notification", when);
NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.layout);
contentView.setTextViewText(R.id.textView1, "Custom notification");
contentView.setOnClickPendingIntent(R.id.button1, pIntent);
notification.contentView = contentView;
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;
notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification
notification.defaults |= Notification.DEFAULT_LIGHTS; // LED
notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration
notification.defaults |= Notification.DEFAULT_SOUND; // Sound
mNotificationManager.notify(1, notification);
但是这个带我去另一个活动.无论如何要对同一活动实施通知操作.
But this one takes me to another activity. Is there anyway to implement notification action on the same activity.
例如..假设我提出了一个通知,当用户按下它时,它不会带我去一些活动,而是在我当前的活动/服务中调用一些常规方法
for example.. let's say i raise a notifcation, and when the user press on it, then instead of take me to some activity, it invoke some regular method in my current activity/service
推荐答案
首先为您的按钮分配一个意图:
First of All assign a intent to your buttons:
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.player_notify_layout);
Intent buttonsIntent = new Intent(context, NotifyActivityHandler.class);
buttonsIntent.putExtra("do_action", "play");
contentView.setOnClickPendingIntent(R.id.imgPlayPause, PendingIntent.getActivity(context, 0, buttonsIntent, 0));
然后创建一个活动来处理通知发生的每个动作:
Then create an activity to handle every action that occurred by notification:
public class NotifyActivityHandler extends Activity {
public static final String PERFORM_NOTIFICATION_BUTTON = "perform_notification_button";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String action = (String) getIntent().getExtras().get("do_action");
if (action != null) {
if (action.equals("play")) {
// for example play a music
} else if (action.equals("close")) {
// close current notification
}
}
finish();
}
}
最后,您应该在 AndroidManifest.xml 中定义活动.您也可以查看此链接.
Finally, you should define activity in AndroidManifest.xml. Also you can check this link.
