android - android - how to change the color of settings button?

Question

The settings button right corner, it became not visible when I applied dark theme on Action Bar. How do I change its color so that it becomes visible? I'm guessing I have to mess with main.xml

android:color="..."

does not work

(this picture's brightness has been increased, normally it is really not visible)

在 onPrepareOptionsMenu(Menu menu) 方法中试试这个......

 menu.findItem(R.id.your_icon).setVisible(true);
