Android - custom highlight background for ClickSpan

Question

Is there a way to set a custom (from resources) resource to a range, especially on ClickSpan, TextView?

Google returns a lot of answers for turning off highlighting or changing colors, etc., overriding the updateDrawState () range, but I don’t see how you can set the highlight for the background.

I see an opportunity in DynamicDrawableSpan, but I can't get it to work with ClickableSpan. This is my code:

public class MyDynamicDrawableSpan extends DynamicDrawableSpan { private Context c; public MyDynamicDrawableSpan(Context context) { super(); c = context; } @Override public Drawable getDrawable() { Resources res = c.getResources(); Drawable d = res.getDrawable(R.drawable.span_background); return d; } 

}

And here is how I use it:

 SpannableStringBuilder ssb = new SpannableStringBuilder(text); MyDynamicDrawableSpan ddSpan = new MyDynamicDrawableSpan(getApplicationContext()); ... ssb.setSpan(ddSpan, start, end, 0); ssb.setSpan(new ClickableSpan(... 

This does not work. This helps to make an invisible range. Any bright ideas?

You need to set Drawable borders before returning to getDrawable ().

 d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
