若要使文本居中,请更改
TextView
宽度以匹配父视图
<RelativeLayout android:id="@+id/card_layout"
>
<TextView android:id="@+id/student_name"
android:layout_width="match_parent" // before it is wrap_content
... />
</RelativeLayout>
使你的底部中心正确
// I organize the flow of your layout from left-to-right
// Before it is right-to-left
<android.support.v7.widget.Toolbar android:id="@+id/card_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_gravity="bottom">
<ImageView android:id="@+id/student_absent"

//我从左到右组织布局的流程
//在它从右向左之前
希望这有帮助
