目前，我正尝试将Tab中的一个TabLayout与其他Tab区别开来。我希望一个具有特定索引的Tab具有红色文本，包括选中和未选中。因为我只要求在特定索引处只有一个app:tabSelectedTextColor="@color/red"
app:tabTextColor="@color/red"
，所以下面的常用解决方案不起作用：
Spannable我还尝试在返回特定Tab的标题时应用@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case TAB_ONE:
return getString(R.string.tab_one);
case TAB_TWO_RED:
Spannable spannable = new SpannableString(getString(R.string.tab_two));
spannable.setSpan(new ForegroundColorSpan(Color.RED),
0, getString(R.string.tab_two).length(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return spannable;
}
return null;
}
，但这实际上并未显示：

设置文本样式，我将非常感激。

这很简单。
尝试将customView设置为TabLayout中的特定标签，如下所示：
TabLayout tabLayout;
tabLayout = (TabLayout) findViewById(R.id.pTabs);
tabLayout.getTabAt(1).setCustomView(R.layout.tab_two_layout);
您的自定义布局（R.layout.tab_two_layout）的XML看起来与此类似：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:textStyle="bold"
android:layout_marginLeft="5dp"
android:layout_marginStart="5dp"
android:layout_width="60dp"
android:textColor="@color/red"
android:layout_gravity="center_vertical"
android:text="TEXT HERE"
android:layout_height="wrap_content"/>
</LinearLayout>
