我的item.xml文件里是1个LinearLayout (a)，里面9个LinearLayout(b)
main.xml里面一个gridview，一行一个item，我想的是每个b按比例显示大小（就是等高）。怎么实现（不能固定死呀，要每个手机上显示b的高度都一样）
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_weight='1'
android:layout_height="wrap_content">
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_weight='1' //关键是设置权重一样就行，就是等高
android:layout_height="wrap_content">
</LinearLayout>
。。。总共9个
<LinearLayout/>
