Android中使用gridview如何让图片在上文字在下

你说的是这样子么？


如果是这样子的话就看源码吧：
gridview.xml

Xml代码






<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>

item.xml

Xml代码






<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:paddingBottom="4dip"
>
<ImageView
android:id="@+id/ItemImage"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerHorizontal="true"
/>
<TextView
android:id="@+id/ItemText"
android:layout_width="wrap_content"
android:layout_below="@+id/ItemImage"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="TextView01"
/>
</RelativeLayout>

activity
