GridView 中的中心元素 [英] Center elements in GridView

问题描述

我的 GridView 有 2 列 6 个图像.我想在屏幕中间显示这 6 个图像.我将重力属性设置为中心，但此中心元素仅水平放置.GridView 占据整个屏幕.

I have GridView with 6 images in 2 columns. I want to display this 6 images in the middle of the screen. I set gravity properties to center but this center elements only horizontally. GridView takes whole screen.

<GridView
    android:id="@+id/gridview"
    android:layout_above="@id/ad" android:layout_alignParentTop="true"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:numColumns="2"    
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:stretchMode="columnWidth"       
    android:background="#ffffff"
    android:gravity="center"
/>

推荐答案

这是我为了让 gridview 中的项目居中而做的事情(注意拉伸模式、列宽、重力以及水平和垂直间距):

Here is what I did to get the items in the gridview to center (notice the stretchmode, columnwidth, gravity and horizontal and vertical spacing):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:padding="5dp" >
    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="100dp"
        android:gravity="center"
        android:horizontalSpacing="10dp"
        android:numColumns="3"
        android:stretchMode="spacingWidthUniform"
        android:verticalSpacing="10dp" />
</LinearLayout>

我花了一些时间才弄明白，但是通过处理这些不同的值，我能够让它们居中.

It took me a while to figure it out, but messing with those different values I was able to get them to center.
