看代碼前,先看一下效果吧

Android GridView屬性集合
1.android:numColumns=”auto_fit” //GridView的列數設定為自動
2.android:columnWidth=”90dp " //每列的寬度,也就是Item的寬度
3.android:stretchMode=”columnWidth"//縮放與列寬大小同步
4.android:verticalSpacing=”10dp” //兩行之間的邊距
5.android:horizontalSpacing=”10dp” //兩列之間的邊距
6.android:cacheColorHint="#00000000" //去除拖動時預設的黑色背景
7.android:listSelector="#00000000" //去除選中時的黃色底色
8.android:scrollbars="none" //隐藏GridView的滾動條
9.android:fadeScrollbars="true" //設定為true就可以實作滾動條的自動隐藏和顯示
10.android:fastScrollEnabled="true" //GridView出現快速滾動的按鈕(至少滾動4頁才會顯示)
11.android:fadingEdge="none" //GridView衰落(褪去)邊緣顔色為空,預設值是vertical。(可以了解為上下邊緣的提示色)
12.android:fadingEdgeLength="10dip" //定義的衰落(褪去)邊緣的長度
13.android:stackFromBottom="true" //設定為true時,你做好的清單就會顯示你清單的最下面
14.android:transcriptMode="alwaysScroll" //當你動态添加資料時,清單将自動往下滾動最新的條目可以自動滾動到可視範圍内
15.android:drawSelectorOnTop="false" //點選某條記錄不放,顔色會在記錄的後面成為背景色,内容的文字可見(預設為false)
簡單實作Android實作九宮格
實作的步驟
1. 一個整體的容器部分。就是上圖中包括整個圖檔項個各個部分,這裡我們使用gridView(表格布局)來實作
2.整個界面裡需要注意的是 “重複的部分”,就是 各個圖檔項和,圖檔下方顯示的文字了。那麼我們需要描述這個部分。在描述時,要說明圖檔位于上方,文字位于下方。
3.疊代,或者說重複的将各項 插入(放入)到容器内。
需要添加/修改3個檔案:main_activity,grid_item.xml,NineBox.java
