private void setActionbarTextColor(ActionBar actBar, int color) {
String title = actBar.getTitle().toString();
Spannable spannablerTitle = new SpannableString(title);
spannablerTitle.setSpan(new ForegroundColorSpan(color), 0, spannablerTitle.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
actBar.setTitle(spannablerTitle);
}
然后使用它只需输入你的动作栏和新的颜色。
ActionBar actionBar = getActionBar(); // Or getSupportActionBar() if using appCompat
int red = Color.RED
setActionbarTextColor(actionBar, red);

你可以像这样使用扩展函数:
private fun ActionBar.setTitleColor(color: Int) {
val text = SpannableString(title ?: "")
text.setSpan(ForegroundColorSpan(color),0,text.length, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
title = text
}
Add Toolbar in the Activity's layout xml. Here we will set our custom (overwritten themes), note android:theme="@style/ThemeOverlay.AppTheme.ActionBar" and app:popupTheme="@style/ThemeOverlay.AppTheme.PopupMenu", they will do the trick.
