布局文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
<TextView
android:id="@+id/tv_view_textview_with_line"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="10dp"
android:text="测试"
android:textColor="@color/white"
android:textSize="12sp" />
<View
android:id="@+id/view_view_textview_with_line"
android:layout_width="30dp"
android:layout_height="1dp"
android:layout_gravity="center_horizontal"
android:background="@color/white" />
</LinearLayout>
</LinearLayout>
如果想改变文字、线的颜色这些,直接修改布局文件中的内容。
