How to use selector to tint ImageView?

Question

I want to tint my tabhost\'s icons using XML, instead of doing it programmatically (I wasn\'t able to do that anyway)...

I found this thread on SO: Android imagevie

In reference to my solution at https://stackoverflow.com/a/18724834/2136792, there are a few things you're missing:

TintableImageView.java

@Override
protected void drawableStateChanged() {
    super.drawableStateChanged();
    if (tint != null && tint.isStateful())
        updateTintColor();
}

public void setColorFilter(ColorStateList tint) {
    this.tint = tint;
    super.setColorFilter(tint.getColorForState(getDrawableState(), 0));
}

private void updateTintColor() {
    int color = tint.getColorForState(getDrawableState(), 0);
    setColorFilter(color);
}

drawableStateChanged() must be overridden for the tint to be updated when the element's state changes.

I'm not sure if referencing a drawable from a drawable might cause an issue, but you can simply move your selector.xml into a folder "/res/color" to reference it with "@color/selector.xml" (aapt merges both /res/values/colors.xml and the /res/color folder).
