How to automatically scale a custom View with ShapeDrawables?

Question

I am writing a custom view for my Android application, that consists of several ShapeDrawables. For these drawables, I have to specify the dimensions using setBounds(). Now, my view will always be square, but I want it to use as much space as I allow it within the parent where it is embedded.

So, right now I call setBounds() with some hardcoded values, but when I specify android:layout_width and android:layout_height, I want my ShapeDrawables to be scaled so that they appear as large as possible.

How can I accomplish this within my custom View class?

Found it myself:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);

    mSize = Math.min(width, height);

    setMeasuredDimension(mSize, mSize);
}
