android:layout_span是一个用于表格布局中的属性,用于指定单元格跨越的列数。具体使用方法如下:
1. 在布局文件中创建一个表格布局,如下所示:
```
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow>
<TextView
android:text="Name"
android:layout_column="1"/>
<TextView
android:text="Age"
android:layout_column="2"/>
<TextView
android:text="Gender"
android:layout_column="3"/>
</TableRow>
<TableRow>
<TextView
android:text="John"
android:layout_column="1"/>
<TextView
android:text="25"
android:layout_column="2"/>
<TextView
android:text="Male"
android:layout_column="3"/>
</TableRow>
<TableRow>
<TextView
android:text="Lisa"
android:layout_column="1"
android:layout_span="2"/>
<TextView
android:text="Female"
android:layout_column="3"/>
</TableRow>
</TableLayout>
```
2. 在需要跨越多列的单元格中,添加android:layout_span属性,指定跨越的列数。例如在第三行中,第一个单元格跨越了2列,可以使用android:layout_span="2",如下所示:
```
<TableRow>
<TextView
android:text="Lisa"
android:layout_column="1"
android:layout_span="2"/>
<TextView
android:text="Female"
android:layout_column="3"/>
</TableRow>
```
这样就可以实现单元格跨越多列的效果。
