Return a global shared Resources object that provides access to only system resources (no application resources), and is not configured for the current screen (can not use dimension units, does not change based on orientation, etc).

Usage

From source file:Main.java

public static Bitmap addLabelToBitmap(Bitmap src, String label) {
    float densityFactor = Resources.getSystem().getDisplayMetrics().density;
    final float textPadding = src.getWidth() * 0.05f;

    Canvas canvas = new Canvas(result);
    Paint textPaint = new Paint();
    textPaint.setAntiAlias(true);/*  w  w  w.j a  v a 2  s  .  co m*/
    textPaint.setTextSize(12 * densityFactor);
    textPaint.setColor(Color.WHITE);
    textPaint.setStrokeWidth(2 * densityFactor);
    textPaint.setShadowLayer(1 * densityFactor, 0, 0, Color.BLACK);

    float textWidth = textPaint.measureText(label);

    float scaleFactor = (src.getWidth() - textPadding * 2) / textWidth;

    canvas.drawBitmap(src, 0, 0, textPaint);

    canvas.save();
    canvas.scale(scaleFactor, scaleFactor);
    float textPosX = (src.getWidth() / scaleFactor - textWidth) / 2;
    float textPosY = (src.getHeight() - textPadding) / scaleFactor;

    canvas.drawText(label, textPosX, textPosY, textPaint);
    canvas.restore();
    return result;
