Android GridView拉伸行高度

Question

I have a GridView and the items in it are not taking the full height. It would be desired for them to stretch the same way they are doing horizontally. Can i achieve that?

The GridView is designed to take the remaining space in a Layout. So its height varies. But it is defined as not scrollable as there is always more than enough space. Is there a solution without manually calculating the height for each item? Or if not can i generically calculate the desired height inside the adapter?

The grid view is defined as follows:

    <GridView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/menu_grid_view"
        android:horizontalSpacing="8dp"
        android:verticalSpacing="8dp"
        android:isScrollContainer="false"
        android:numColumns="3"
        android:scrollbars="none"
        android:stretchMode="columnWidth"/>

I also tried it with layout_height=0,layout_weight=1 on the items. But it would be a nested weight and it does not work.

May be you want this to be done.

weight will work only with linear layout.

you can try this I hope this will help you to understand the issue why you are not getting correct layout.

<?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"
    android:weightSum="1">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight=".3"
        android:text="textview"/>

    <GridView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight=".7"
        android:id="@+id/menu_grid_view"
        android:horizontalSpacing="8dp"
        android:verticalSpacing="8dp"
        android:isScrollContainer="false"
        android:numColumns="3"
        android:scrollbars="none"
        android:stretchMode="columnWidth"/>

</LinearLayout>
