推荐答案

像这样从 Java 代码或 XML 创建一个 TextView

Create a TextView from Java Code or XML like this

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:textSize="15sp"
    android:textColor="@color/tabs_default_color"
    android:gravity="center"
    android:layout_height="match_parent"
/>

请确保将 id 保持原样，因为如果您使用自定义文本视图，TabLayout 会检查此 ID

Make sure to keep the id as it is here because the TabLayout check for this ID if you use custom textview

然后从代码中扩展这个布局并在那个 textview 上设置自定义 Typeface 并将这个自定义视图添加到选项卡

Then from code inflate this layout and set the custom Typeface on that textview and add this custom view to the tab

for (int i = 0; i < tabLayout.getTabCount(); i++) {
     //noinspection ConstantConditions
     TextView tv = (TextView)LayoutInflater.from(this).inflate(R.layout.custom_tab,null)
     tv.setTypeface(Typeface);       
     tabLayout.getTabAt(i).setCustomView(tv);
}
