Is there a way of customizing each Google Maps marker in Android Studio?

Question

I am building a Google maps app. I have different objects with coordinates but each object has a unique int value which I would like to be shown next to a marker. For example for an object with specific coordinates and value 123, I would like to put on the map(at those coords) the marker and next to it the value 123.

I've been doing some research and the only way I found plausible is to use an Android API to create your own bitmap image from a base image and some string that is "attached" and use that for the marker icon.

Is there a better way of doing that?
On the same topic, can you show the title of every marker on your map at the same time?

Please see the link. The snipet is used to add text on the maker which can also be customized.

Yes @kisslory you can fully customize each marker to suit your need.

While setting the bitmap for each marker you can create a new bitmap with from a given resource using the method below.

public static Bitmap drawTextToBitmap(Context gContext,
                               int gResId,
                               String gText) {
    Resources resources = gContext.getResources();
    float scale = resources.getDisplayMetrics().density;
    Bitmap bitmap =
            BitmapFactory.decodeResource(resources, gResId);

    android.graphics.Bitmap.Config bitmapConfig = bitmap.getConfig();
    // set default bitmap config if none
    if(bitmapConfig == null) {
        bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
    }
    // resource bitmaps are imutable,
    // so we need to convert it to mutable one
    bitmap = bitmap.copy(bitmapConfig, true);

    Canvas canvas = new Canvas(bitmap);
    // new antialised Paint
    Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
    // text color - #3D3D3D
    paint.setColor(Color.rgb(61, 61, 61));
    // text size in pixels
    paint.setTextSize((int) (14 * scale));
    // text shadow
    paint.setShadowLayer(1f, 0f, 1f, Color.WHITE);

    // draw text to the Canvas center
    Rect bounds = new Rect();
    paint.getTextBounds(gText, 0, gText.length(), bounds);
    int x = (bitmap.getWidth() - bounds.width())/2;
    int y = (bitmap.getHeight() + bounds.height())/2;

    canvas.drawText(gText, x, y, paint);

    return bitmap;
}
