我正在使用多个通知的此类应用程序.每个通知都有播放暂停图标,用于执行音乐播放器的播放/暂停.但是更新通知的行为很奇怪,通知在更新时一直闪烁.
我的代码如下
@SuppressLint("NewApi")
public void UpdateNotificationfunction(int currentNotificationNo) {
PendingIntent pendingIntent = null;
PendingIntent pendingIntent1 = null;
PendingIntent pendingIntent2 = null;
PendingIntent pendingIntent3 = null;
PendingIntent pendingIntent4 = null;
PendingIntent pendingIntent5 = null;
if (mRemoteViews1 == null || newRemoteview) {
Log.d("LOG", "mRemoteViews is null 123");
mRemoteViews1 = new RemoteViews(getPackageName(),
R.layout.custom_notification);
newRemoteview = false;
} else {
if (mState == State.Paused || mState == State.Stopped) {
try {
mRemoteViews1.setimageViewResource(R.id.playpush,
R.drawable.playdetailfornoti);
} catch (Exception e) {
}
} else if (mState == State.Playing) {
try {
mRemoteViews1.setimageViewResource(R.id.playpush,
R.drawable.pushdetail);
} catch (Exception e) {
}
} else if (mState == State.Retrieving) {
try {
Log.e("LOG", "else Retrieving");
mRemoteViews1.setimageViewResource(R.id.playpush,
R.drawable.playdetailfornoti);
} catch (Exception e) {
}
} else {
try {
Log.e("LOG", "else");
if (NetworkUtil.isNetworkAvailable(_context)) {
mRemoteViews1.setimageViewResource(R.id.playpush,
R.drawable.pushdetail);
}
else {
mRemoteViews1.setimageViewResource(R.id.playpush,
R.drawable.playdetailfornoti);
}
} catch (Exception e) {
}
}
}

.setonlyAlertOnce(true)
.setContent(mRemoteViews1).setongoing(false).build();
/*}
else {
mNotification1.contentView = mRemoteViews1;
}*/ //this comment solve my same id issue , I have put this for avoid blinking of notification
.setContent(mRemoteViews1).setongoing(false).build();
mnotificationmanager.notify(currentNotificationNo, mNotification1);
}
请帮我
解决方法:
尝试了很多之后,我找到了闪烁问题和重复的deleteintent问题的解决方案
if (mNotification1 == null) {
// create when notification not avalible
mNotification1 = new NotificationCompat2.Builder(
getApplicationContext()).setSmallIcon(R.drawable.ic_launcher)
.setWhen(System.currentTimeMillis())
.setPriority(Notification.PRIORITY_DEFAULT)
.setDeleteIntent(pendingIntent1).setAutoCancel(true)
.setonlyAlertOnce(true)
.setContent(mRemoteViews1).setongoing(false).build();
}
else {
// this code will solve the blink issue
mNotification1.deleteIntent = pendingIntent1; // this will solve the deleteintent issue
mNotification1.contentView = mRemoteViews1;
}
