Question

我打算制作自定义通知栏。但不是很好。我想创建一个大图标。

      remoteViews = new RemoteViews(getPackageName(), R.layout.widget_main);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
                .setContentTitle("Title")
                .setTicker("Ticker")
                .setSmallIcon(R.mipmap.howlong)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.howlong))//I dot understand why entering this icon.
                .setContent(remoteViews).setOngoing(true);

这是我的代码。

这是我的通知状态。

如何放置大图标？

private Bitmap getCircleBitmap(Bitmap bitmap) {
        final Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
                bitmap.getHeight(), Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(output);

        final int color = Color.RED;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
        final RectF rectF = new RectF(rect);

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        canvas.drawOval(rectF, paint);

        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);

        bitmap.recycle();

        return output;
    }
