Example 1
@NonNull

    @SuppressLint("InflateParams")
    TextView clusterIconView = (TextView) LayoutInflater.from(mContext)
            .inflate(R.layout.map_cluster_icon, null);
    clusterIconView.setBackground(createClusterBackground());
    clusterIconView.setTextColor(mIconStyle.getClusterTextColor());
    clusterIconView.setTextSize(TypedValue.COMPLEX_UNIT_PX,
            mIconStyle.getClusterTextSize());

    clusterIconView.setText(getClusterIconText(clusterBucket));

    clusterIconView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
    clusterIconView.layout(0, 0, clusterIconView.getMeasuredWidth(),
            clusterIconView.getMeasuredHeight());

    Bitmap iconBitmap = Bitmap.createBitmap(clusterIconView.getMeasuredWidth(),
            clusterIconView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);

    Canvas canvas = new Canvas(iconBitmap);
    clusterIconView.draw(canvas);
