Android 通知未在 Marshmallow 中显示颜色图标 [英] Android Notification is not showing Colour Icon in Marshmallow

问题描述

我正在制作应用程序是我从Parse 获取数据并将该数据传输到通知以生成并向用户显示.

但由于某些原因，我无法在棉花糖中显示正确的彩色图标

在所有其他 Android 版本中，它的工作完全正常，但在 Marshmallow 中，它令人毛骨悚然的白色图标不是我选择的实际图标.

这是我的通知代码.

 Intent cIntent = new Intent(context, MainActivity.class);PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,cIntent, PendingIntent.FLAG_UPDATE_CURRENT);NotificationCompat.Builder builder = new NotificationCompat.Builder(context).setSmallIcon(R.drawable.ic_launcher).setContentText(数据).setContentTitle("来自解析的通知").setContentIntent(pendingIntent);通知通知 = builder.build();NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);nm.notify(100, 通知);

请帮我解决这个问题，或者告诉我如何解决这个问题.

解决方案

第一:它不是来自 Marshmallow，通知图标开始从 Lollipop 本身变成白色.

结帐

您也可以使用.setColor()设置通知图标背景的颜色.

I am Making application is which i am getting data fromParse and transfering that data to Notification to generate and show it to user.

But for Some Reason I am unable to show correct Coloured Icon in Marshmallow

In every other Android Version its working totally fine, but in Marshmallow its creepy white icon not actual which i select.

Here is my Code of Notification.

 Intent cIntent = new Intent(context, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                cIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentText(data)
                .setContentTitle("Notification from Parse")
                .setContentIntent(pendingIntent);

        Notification notification = builder.build();
        NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        nm.notify(100, notification);

Please Help me with this, or tell me any other way how to get rid of this problem.

解决方案

First : Its not from Marshmallow, Notification icon started turning out WHITE from Lollipop itself.

Checkout http://developer.android.com/design/style/iconography.html you will see that the white style is how notifications are meant to be displayed in Android Lollipop.

In Android Lollipop, Google also suggests you to use a color that will be displayed behind the (white) notification icon - https://developer.android.com/about/versions/android-5.0-changes.html

Second : Solution to this is setting LargeIcon to Notification Builder

Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);

NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setLargeIcon(largeIcon)
                .setContentText(data)
                .setContentTitle("Notification from Parse")
                .setContentIntent(pendingIntent);

then, your Notification will look something like this :

You can also set the color to background of Notification Icon by using .setColor().
