android - TabLayout tabItem tabGravity center 不工作

Question

它在超过 5 个标签时工作正常，但当 3 个标签看起来不太好时。
这是我的 TabLayout XML 代码:

 <android.support.design.widget.TabLayout
            android:gravity="center"
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/search_bar"
            android:fillViewport="false"
            app:tabGravity="center"
            app:tabIndicatorColor="@color/ThemeColor"
            app:tabIndicatorHeight="6dp"
            app:tabMode="scrollable"
            android:paddingBottom="2dp"
            android:background="@drawable/bottom_dotted_border"
            app:tabSelectedTextColor="@color/ThemeColor"
            app:tabTextAppearance="@style/TabLayoutTextStyle"
            app:tabTextColor="@color/White" />

只是改变这个 app:tabMode="scrollable" 到 app:tabMode="fixed" < strong>在你的标签布局中

1. app:tabMode="fixed : the tabs are fixed in your tab layout (its not good for when your tabs have long tabtitles)

2. tabMode:scrollable - you can scroll your tabs horizontally when your tabs have long tabtitles

示例代码

<android.support.design.widget.TabLayout
        android:gravity="center"
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/search_bar"
        android:fillViewport="false"
        app:tabGravity="fill"
        app:tabMode="fixed"
        app:tabIndicatorColor="@color/ThemeColor"
        app:tabIndicatorHeight="6dp"
        android:paddingBottom="2dp"
        android:background="@drawable/bottom_dotted_border"
        app:tabSelectedTextColor="@color/ThemeColor"
        app:tabTextAppearance="@style/TabLayoutTextStyle"
        app:tabTextColor="@color/White" />
