AndroidToolbar action text colour cannot be set programatically #3215
Description
I realize this is not an API that exists in Android, but that doesn't mean we can't do it 😀

final PorterDuffColorFilter colorFilter
= new PorterDuffColorFilter(toolbarIconsColor, PorterDuff.Mode.MULTIPLY);
for(int i = 0; i < toolbarView.getChildCount(); i++) {
final View v = toolbarView.getChildAt(i);
//Step 1 : Changing the color of back button (or open drawer button).
if(v instanceof ImageButton) {
//Action Bar back button
((ImageButton)v).getDrawable().setColorFilter(colorFilter);
}
if(v instanceof ActionMenuView) {
for(int j = 0; j < ((ActionMenuView)v).getChildCount(); j++) {
//Step 2: Changing the color of any ActionMenuViews - icons that
//are not back button, nor text, nor overflow menu icon.
final View innerView = ((ActionMenuView)v).getChildAt(j);
if(innerView instanceof ActionMenuItemView) {
int drawablesCount = ((ActionMenuItemView)innerView).getCompoundDrawables().length;
for(int k = 0; k < drawablesCount; k++) {
if(((ActionMenuItemView)innerView).getCompoundDrawables()[k] != null) {
final int finalK = k;
//Important to set the color filter in seperate thread,
//by adding it to the message queue
//Won't work otherwise.
innerView.post(new Runnable() {
@Override
public void run() {
((ActionMenuItemView) innerView).getCompoundDrawables()[finalK].setColorFilter(colorFilter);
}
});
}
}
}
}
}
