首先我不知道您的通知在哪些设备上无法正常工作,比如Oreo,Pie还是N以下的版本。
对于您的问题,StackOver Flow有很多答案。
现在根据您的问题,您只缺少一行代码,但由于您还没有粘贴整个通知代码,因此无法检查。
这里我粘贴了一段通知代码,可以满足您所有的通知要求。(完全自定义通知)
带图片的通知
public void createNotificationWithImage(String title,String message ,Bitmap image) {
PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext,
0 , resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
Uri soundUri = Uri.parse("android.resource://" + mContext.getApplicationContext()
.getPackageName() + "/" + R.raw.sniper_gun);
mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.notification_icon);
mBuilder.setSound(soundUri);
if (image!=null) {
mBuilder.setContentTitle(title)
.setContentText(message)
.setAutoCancel(false)
.setLargeIcon(image)
.setStyle(new NotificationCompat.BigPictureStyle()
.bigPicture(image).setSummaryText(message).bigLargeIcon(null))
.setColor(Color.GREEN)
.setContentIntent(resultPendingIntent);
}
mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
现在我将粘贴一个通知代码,它可以在OREO设备上运行。
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
if(soundUri != null){
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_ALARM)
.build();
notificationChannel.setSound(soundUri,audioAttributes);
}
assert mNotificationManager != null;
mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
mNotificationManager.createNotificationChannel(notificationChannel);
}
assert mNotificationManager != null;
mNotificationManager.notify(0 , mBuilder.build());
below middle braces use for close your method.
}
没有图片的通知
public void createNotification(String title,String message){
PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext,
0 , resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
Uri soundUri = Uri.parse("android.resource://" + mContext.getApplicationContext()
.getPackageName() + "/" + R.raw.sniper_gun);
mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.notification_icon);
mBuilder.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(),
R.mipmap.icon));
mBuilder.setSound(soundUri);
mBuilder.setContentTitle(title)
.setContentText(message)
.setAutoCancel(false)
.setColor(Color.GREEN)
.setStyle(new NotificationCompat.BigTextStyle())
.setContentIntent(resultPendingIntent);
mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
if(soundUri != null){
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_ALARM)
.build();
notificationChannel.setSound(soundUri,audioAttributes);
}
assert mNotificationManager != null;
mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
mNotificationManager.createNotificationChannel(notificationChannel);
}
assert mNotificationManager != null;
mNotificationManager.notify(0 , mBuilder.build());
}
注意:在我的代码中,我提到了一个特定的行,请关注我所描述的设置使用通知时的声音Uri。
mBuilder.setContentTitle(title)
.setContentText(message)
.setAutoCancel(false)
.setSound(soundUri)
.setColor(Color.GREEN)
.setStyle(new NotificationCompat.BigTextStyle())
.setContentIntent(resultPendingIntent);
但是它不会发出声音,因为在Oreo设备中,声音没有被设置为优先级。
因此,始终使用我描述的代码来处理声音。
