我有播放收音机的服务&创建通知。通知必须包括标题、文本、时间和;一个按钮(暂停/播放)。我已经添加了其余的东西&正在显示通知。但我不确定如何将按钮添加到通知中。在搜索中,我发现我可以使用RemoteView、RemoteControlClient&媒体样式。但是RemoteControlClient&当媒体文件使用所有按钮(上一个、暂停、播放、后退)播放时,将使用媒体样式。所以我真的很困惑。有人能建议我,用哪一个来添加Lollypop通知中的按钮吗。
首先,您需要知道addAction
在23 API中已弃用,请阅读此内容以关联
调用showNotification()
方法显示通知
private void showActionButtonsNotification() {
Notification.Builder notif;
NotificationManager nm;
notif = new Notification.Builder(getApplicationContext());
notif.setSmallIcon(R.mipmap.ic_launcher);
notif.setContentTitle("Hi there!");
notif.setContentText("This is even more text.");
Uri path = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notif.setSound(path);
nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent yesReceive = new Intent();
yesReceive.setAction(MyNotificationReceiver.RESUME_ACTION);
PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, MyNotificationReceiver.REQUEST_CODE_NOTIFICATION, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);
notif.addAction(R.drawable.resume, "resume", pendingIntentYes);
Intent yesReceive2 = new Intent();
yesReceive2.setAction(MyNotificationReceiver.STOP_ACTION);
PendingIntent pendingIntentYes2 = PendingIntent.getBroadcast(this, MyNotificationReceiver.REQUEST_CODE_NOTIFICATION, yesReceive2, PendingIntent.FLAG_UPDATE_CURRENT);
notif.addAction(R.drawable.stop, "stop", pendingIntentYes2);
Intent maybeReceive2 = new Intent();
maybeReceive2.setAction(MyNotificationReceiver.CANCEL_ACTION);
PendingIntent pendingIntentMaybe2 = PendingIntent.getBroadcast(this, MyNotificationReceiver.REQUEST_CODE_NOTIFICATION, maybeReceive2, PendingIntent.FLAG_UPDATE_CURRENT);
notif.addAction(R.drawable.cancel, "cancel", pendingIntentMaybe2);
assert nm != null;
nm.notify(MyNotificationReceiver.REQUEST_CODE, notif.getNotification());
}
创建MyNotificationReceiver
类以接收点击
public class MyNotificationReceiver extends BroadcastReceiver {
public static int REQUEST_CODE_NOTIFICATION = 1212;
public static int REQUEST_CODE = 10;
public static final String RESUME_ACTION = "RESUME_ACTION";
public static final String STOP_ACTION = "STOP_ACTION";
public static final String CANCEL_ACTION = "CANCEL_ACTION";
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.e("action", action);
if (intent.getAction() != null) {
switch (intent.getAction()) {
case RESUME_ACTION :
Toast.makeText(context, "resume", Toast.LENGTH_SHORT).show();
// you resume action
break;
case STOP_ACTION :
Toast.makeText(context, "stop", Toast.LENGTH_SHORT).show();
// you stop action
break;
case CANCEL_ACTION:
Toast.makeText(context, "cancel", Toast.LENGTH_SHORT).show();
// you cancel action
break;
}
}
}
}
最后,将receiver
添加到manifests
中
<receiver android:name=".MyNotificationReceiver">
<intent-filter>
<action android:name="RESUME_ACTION"/>
<action android:name="STOP_ACTION"/>
<action android:name="CANCEL_ACTION"/>
</intent-filter>
</receiver>
