Android XML：将TabHost样式设置为小写文本

Question

我正在为我的Android应用程序实现标签布局。我尝试将每个标签设置为textAllCaps设置为false（app:tabTextAppearance="@style/MyCustomTextAppearance"）的某种样式，但是这对我不起作用。这个问题不是重复的，因为我正在[[未使用 TabLayout，正在使用TabHost。下面是我的代码：

styles.xml

中的样式：

<style name="MyCustomTextAppearance" parent="TextAppearance.Design.Tab">
    <item name="textAllCaps">false</item>
</style>

content_main.xml

：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent">

        app:tabTextAppearance="@style/MyCustomTextAppearance"
        tools:showIn="@layout/activity_main">

        <TabHost

            />

    </androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>

下面是我的应用程序的外观（选项卡的文本仍然大写）：

Answer 1

在tabLayout上应用以下样式

app:tabTextAppearance="@android:style/TextAppearance.Widget.TabWidget"

Answer 2

使用它并更改与颜色相同的样式

for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
            View v = tabHost.getTabWidget().getChildAt(i);
            v.setBackgroundResource(R.drawable.tabs);

            TextView tv = (TextView) tabHost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
            tv.setTextColor(getResources().getColor(R.color.white));
}
