Just put the hedxadecimal code of color in

只需将颜色的hedxadecimal代码放入

android:textColor="#0000000"

#2

android:textColor="@color/base_tabpager_indicator_color"

base_tabpager_indicator_color.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_checked="true" android:color="#fffb9749" />
   <item android:color="#ffffffff" />
</selector>

#3

simple, just add

简单,只需添加

android:hint="your text"
android:textColorHint="YourColor"

instead of text and androidTextColor

而不是文本和androidTextColor
