Question

我正在制作一个项目，我需要在其中显示带图像的自定义notifications，它在所有手机中都运行良好，但在“MI redmi note 4” 它不能扩展。我已经尝试了下面的代码，除了MI redmi note 4之外，所有其他设备都能正常工作。有没有解决方法呢？请帮帮我。

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        notification();
    }

    private void notification() {

        NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.customnoti);
        contentView.setImageViewResource(R.id.image, R.mipmap.ic_launcher);
        contentView.setImageViewResource(R.id.dec_img, R.mipmap.ic_launcher);
        contentView.setTextViewText(R.id.title, "Custom notification");
        contentView.setTextViewText(R.id.text, "This is a custom layout");

        NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setPriority(Notification.PRIORITY_MAX)
                .setContent(contentView)
                ;

        Notification notification = mBuilder.build();


        if (Build.VERSION.SDK_INT >= 16) {
            // Inflate and set the layout for the expanded notification view
            RemoteViews expandedView =
                    new RemoteViews(getPackageName(), R.layout.customnoti);
            notification.bigContentView = expandedView;
        }

        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notification.defaults |= Notification.DEFAULT_SOUND;
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationmanager.notify(1, notification);

    }
}

customnoti.xml

<?xml version="1.0" encoding="utf-8"?>

        <TextView

            android:layout_toRightOf="@id/image"
            android:layout_below="@id/title"
            />
    </RelativeLayout>

    <ImageView

        android:src="@mipmap/ic_launcher"

        android:layout_alignParentLeft="true"
        android:layout_marginRight="10dp" />
