    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

    <!--
        Theme customizations available in newer API levels can go in

        backward-compatibility can go here.

</style>




<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:actionBarStyle">@style/MyActionBarTheme</item>

Answer 1

您可以在MainActivity中调用这些覆盖方法并在那里更改文本

 @Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
    // TODO Auto-generated method stub
    //Change color here!!
}

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
    // TODO Auto-generated method stub
    // on tab selected
    // show respected fragment view
    viewPager.setCurrentItem(tab.getPosition());
tab.setTabTextColors(ContextCompat.getColor(mContext, R.color.white);

}

@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    // TODO Auto-generated method stub

}

希望这可能有助于你的事业， 如果没有给我留言。

你可以

@覆盖 public void onTabSelected（Tab tab，FragmentTransaction ft）{

//在选项卡上

viewPager.setCurrentItem（tab.getPosition（））;

//在这里您可以处理选项卡

}
