From source file:Main.java

public static boolean drawDrawables(Canvas canvas, @Nonnull TextView textView) {

    final int scrollX = textView.getScrollX();
    final int scrollY = textView.getScrollY();

    final int right = textView.getRight();
    final int left = textView.getLeft();
    final int bottom = textView.getBottom();
    final int top = textView.getTop();

    final Drawable[] drawables = textView.getCompoundDrawables();
    if (drawables != null) {

        int vspace = bottom - top - compoundPaddingBottom - compoundPaddingTop;

        Drawable topDr = drawables[1];// w w w  .  j a v a 2  s .c o m
        // IMPORTANT: The coordinates computed are also used in invalidateDrawable()
        // Make sure to update invalidateDrawable() when changing this code.
        if (topDr != null) {
            canvas.save();
            canvas.translate(scrollX + compoundPaddingLeft + (hspace - topDr.getBounds().width()) / 2,
                    scrollY + textView.getPaddingTop() + vspace / 2);
