在GridView的中心元素元素、中心、GridView

我的GridView 6图像2列。我想在屏幕中间显示这6幅图像。我把重心属性中心,但该中心的元素只会水平。 GridView控件需要整个屏幕。

 < GridView控件
    机器人:ID =@ + ID / GridView控件
    机器人:layout_above =@ ID /广告安卓:layout_alignParentTop =真
    机器人:layout_width =FILL_PARENT
    机器人:layout_height =FILL_PARENT
    机器人:为numColumns =2
    机器人:verticalSpacing =10dp
    机器人:horizo​​ntalSpacing =10dp
    机器人:stretchMode =columnWidth中
    机器人:后台=#FFFFFF
    机器人:重力=中心
/>
 

解决方案

下面是我做过什么让在GridView的项目中心(注意stretchmode,columnWidth中,重力和水平和垂直间距):

 < LinearLayout中的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
    机器人:layout_width =FILL_PARENT
    机器人:layout_height =FILL_PARENT
    机器人:方向=横向
    机器人:填充=5dip>
    < GridView控件
        机器人:ID =@ + ID / GridView控件
        机器人:layout_width =match_parent
        机器人:layout_height =match_parent
        机器人:columnWidth中=100dip
        机器人:重力=中心
        机器人:horizo​​ntalSpacing =10dip
        机器人:为numColumns =3
        机器人:stretchMode =spacingWidthUniform
        机器人:verticalSpacing =10dip/>
< / LinearLayout中>
 
.net中gridview如何批量添加数据到表中

我花了一段时间来弄明白,但与这些不同的价值观,我能够让他们心搞乱。

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"
/>

解决方案

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="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:padding="5dip" >
    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="100dip"
        android:gravity="center"
        android:horizontalSpacing="10dip"
        android:numColumns="3"
        android:stretchMode="spacingWidthUniform"
        android:verticalSpacing="10dip" />
</LinearLayout>

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