在android中完全没有在标签布局中集中对齐的文本视图

Question

我正在为我的应用程序使用标签布局，但是当我尝试使用它时，我想确保我为标签布局设置的文本应该居中对齐，我尝试了不同的教程，其中我已成功但有一些问题。每当我点击标签时，标签的文字会略微向上移动，使我的屏幕也会受到干扰，当我第一次点击该屏幕时，标签下方会出现灰色线条。我使用了android:tabStripEnabled="false"，但没有用

这是我的xml

<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="match_parent"
        android:layout_height="30dp"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="20dp"
        android:background="@drawable/buttonclientoption" 
        android:layout_gravity="center"
        android:tabStripEnabled="false"/>

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
</LinearLayout>    

这是我的代码
