【Android】九宮格實現

第一步，布局檔案

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".JokeTabHostActivity"    android:orientation="vertical"    >    <GridView         android:id="@+id/GridView"        android:listSelector="@android:color/transparent"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:columnWidth="90dp"        android:gravity="center"        android:numColumns="auto_fit"        android:layout_marginTop="10dp"        android:stretchMode="columnWidth">    </GridView></LinearLayout>

第二步，在你的activity  中調用初始化Grid

GridView gridview = (GridView) findViewById(R.id.GridView);ArrayList<HashMap<String, Object>> meumList = new ArrayList<HashMap<String, Object>>();for (int i = 1; i < 4; i++) {HashMap<String, Object> map = new HashMap<String, Object>();if (i == 1) {map.put("ItemImage", R.drawable.a1);map.put("ItemText", "文章精選");} else if (i == 2) {map.put("ItemImage", R.drawable.a2);map.put("ItemText", "幽默笑話");} else {map.put("ItemImage", R.drawable.a5);map.put("ItemText", "期待很多其它");}meumList.add(map);}SimpleAdapter saItem = new SimpleAdapter(this, meumList, // 資料來源R.layout.item, // xml實現new String[] { "ItemImage", "ItemText" }, // 相應map的Keynew int[] { R.id.ItemImage, R.id.ItemText }); // 相應R的Id// //加入Item到網格中gridview.setAdapter(saItem); // 加入點擊事件gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {@SuppressWarnings("static-access")public void onItemClick(AdapterView<?
> arg0, View arg1, int arg2,long arg3) {int index = arg2 + 1;// id是從0開始的，所以須要+1if (index == 1) {Intent intent = new Intent();intent.setClass(MainActivity.this,CloseTabHostActivity.class);startActivity(intent);}if (index == 2) { Intent intent = new Intent(); intent.setClass(MainActivity.this, XListViewActivity.class); startActivity(intent);//showInfo("正在努力碼代碼中。。。
");// finish();//停止當前的Activity,假設不寫,則按返回鍵會跳回原來的Activity}if (index == 3) {showInfo("期待你的建議，好建議請Q 649175826");}}});
