使用自定义布局在 ListFragment 顶部居中对齐 TextView
Center-align TextView on top of ListFragment with custom layout
在a simple test app at GitHub I am trying to display a user avatar, then two TextView
s Username and City (which should be center-aligned) and finally the main ListView
of the ListFragment中:
在布局文件 fragment_account.xml 中,我尝试为两个 TextView
设置 android:textAlignment="center"
(在上面的屏幕截图中用红色箭头标记),但是没有任何效果 - 可能是因为该应用程序适用于 minSdkLevel=9?
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/avatar"
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_gravity="center_horizontal"
android:src="@drawable/photo"
app:border_width="2dp"
app:border_color="#FFF"/>
<TextView <!-- how to center-align? -->
android:id="@+id/username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAlignment="center"
android:text="Username"/>
<TextView <!-- how to center-align? -->
android:id="@+id/city"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAlignment="center"
android:text="City"/>
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
请指教,如果有一个好的方法可以使这些标签居中对齐。
试试这个
