Is it possible to scale drawableleft & drawableright in textview?

Question

I have TextView with drawableLeft & drawableRight in List item. The problem is, whenever the height of TextView is l

Answer 1

I solved an equivalent usecase by introducing a ScaleDrawable and overriding its .getIntrisicHeight() so that it is at least the TextView height. The TextView.addOnLayoutChangeListener part, required to rebind the Drawable on a TextView size change works with API11+

Drawable underlyingDrawable = 
        new BitmapDrawable(context.getResources(), result);

// Wrap to scale up to the TextView height
final ScaleDrawable scaledLeft = 
        new ScaleDrawable(underlyingDrawable, Gravity.CENTER, 1F, 1F) {
    // Give this drawable a height being at
    // least the TextView height. It will be
    // used by
    // TextView.setCompoundDrawablesWithIntrinsicBounds
    public int getIntrinsicHeight() {
        return Math.max(super.getIntrinsicHeight(), 
                        competitorView.getHeight());
    };
};

// Set explicitly level else the default value
// (0) will prevent .draw to effectively draw
// the underlying Drawable
scaledLeft.setLevel(10000);

// Set the drawable as a component of the
// TextView
competitorView.setCompoundDrawablesWithIntrinsicBounds(
        scaledLeft, null, null, null);

// If the text is changed, we need to
// re-register the Drawable to recompute the
// bounds given the new TextView height
competitorView.addOnLayoutChangeListener(new OnLayoutChangeListener() {

    @Override
    public void onLayoutChange(View v, int left, int top, int right, 
            int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
        competitorView.setCompoundDrawablesWithIntrinsicBounds(scaledLeft, null, null, null);
    }
});
