Sometimes you may need to make a TextView (label) look a little transparent to make emphasis on other parts of your UI. The .setAlpha() function on TextView is not supported after later in the SDK. Here’s a static workaround you can place on some sort of UIUtils class you may have in your project.
[java]
/**
* Android devices with SDK below target=11 do not support textView.setAlpha().
* This is a work around.
* @param v – the text view
* @param alpha – a value from 0 to 255. (0=transparent, 255=fully visible)
*/
public static void setTextViewAlpha(TextView v, int alpha) {
v.setTextColor(v.getTextColors().withAlpha(alpha));
v.setHintTextColor(v.getHintTextColors().withAlpha(alpha));
v.setLinkTextColor(v.getLinkTextColors().withAlpha(alpha));
Drawable[] compoundDrawables = v.getCompoundDrawables();
for (int i=0 ; i < compoundDrawables.length; i++) {
Drawable d = compoundDrawables[i];
if (d != null) {
d.setAlpha(alpha);
}
}
}
[/java]
Enjoy, and above all
