可以混用LinearLayout和RelativeLayout,具体如下:
1.首先,在布局文件中使用LinearLayout作为根布局。
2.在LinearLayout中添加一个RelativeLayout,设置其宽度和高度为match_parent。
3.在RelativeLayout中添加需要的控件,可以使用相对布局的方式进行布局。
4.如果需要在LinearLayout中添加其他控件,可以直接添加。
5.使用layout_weight属性可以实现LinearLayout中控件的权重分配。
例如:
```
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RelativeLayout中的控件"
android:layout_centerInParent="true"
/>
</RelativeLayout>
<Button
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="LinearLayout中的控件"
/>
</LinearLayout>
```
在该布局中,RelativeLayout占据了LinearLayout的一半高度,而Button占据了另一半高度。在RelativeLayout中,TextView使用相对布局的方式垂直居中。
