Android中使用gridview如何讓圖片在上文字在下

你說的是這樣子嗎？
如果是這樣子的話就看源碼吧：
gridview.xml Xml代碼  

1. <?xml version="1.0" encoding="utf-8"?>  
2. <GridView xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:id="@+id/gridview"  
4.     android:layout_width="fill_parent"  
5.     android:layout_height="fill_parent"  
6.     android:numColumns="auto_fit"  
7.     android:verticalSpacing="10dp"  
8.     android:horizontalSpacing="10dp"  
9.     android:columnWidth="90dp"  
10.     android:stretchMode="columnWidth"  
11.     android:gravity="center"    
12.     />  

<?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代碼  

1. <?xml version="1.0" encoding="utf-8"?>  
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:layout_height="wrap_content"  
4.     android:layout_width="fill_parent"  
5.     android:paddingBottom="4dip"  
6.     >  
7.     <ImageView  
8.         android:id="@+id/ItemImage"  
9.         android:layout_height="wrap_content"  
10.         android:layout_width="wrap_content"  
11.         android:layout_centerHorizontal="true"  
12.         />  
13.     <TextView  
14.         android:id="@+id/ItemText"  
15.         android:layout_width="wrap_content"  
16.         android:layout_below="@+id/ItemImage"  
17.         android:layout_height="wrap_content"  
18.         android:layout_centerHorizontal="true"  
19.         android:text="TextView01"  
20.         />  
21. </RelativeLayout>  

<?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"><ImageViewandroid:id="@+id/ItemImage"android:layout_height="wrap_content"android:layout_width="wrap_content"android:layout_centerHorizontal="true"/><TextViewandroid: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>
