//安卓开发所需要的GridView布局（九宫格布局）完美使用

public class MainActivity extends Activity {
private String texts[] = null;
private int images[] = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

images=new int[]{R.drawable.p8, R.drawable.p2,
R.drawable.p3, R.drawable.p4,
R.drawable.p5,R.drawable.p6,
R.drawable.p7,R.drawable.p8};
texts = new String[]{ "宫式布局1", "宫式布局2",
"宫式布局3", "宫式布局4",
"宫式布局5", "宫式布局6",
"宫式布局7", "宫式布局8"};
GridView gridview = (GridView) findViewById(R.id.gridview);
ArrayList<HashMap<String, Object>> lstImageItem = new ArrayList<HashMap<String, Object>>();
for (int i = 0; i < 8; i++) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("itemImage", images[i]);
map.put("itemText", texts[i]);
lstImageItem.add(map);
}

SimpleAdapter saImageItems = new SimpleAdapter(this,
lstImageItem,// 数据源
R.layout.night_item,// 显示布局
new String[] { "itemImage", "itemText" },
new int[] { R.id.itemImage, R.id.itemText });
gridview.setAdapter(saImageItems);
gridview.setOnItemClickListener(new ItemClickListener());
}

class ItemClickListener implements OnItemClickListener {
/**
* 点击项时触发事件
*
* @param parent 发生点击动作的AdapterView
* @param view 在AdapterView中被点击的视图(它是由adapter提供的一个视图)。
* @param position 视图在adapter中的位置。
* @param rowid 被点击元素的行id。
*/
public void onItemClick(AdapterView<?> parent, View view, int position, long rowid) {
HashMap<String, Object> item = (HashMap<String, Object>) parent.getItemAtPosition(position);
//获取数据源的属性值
String itemText=(String)item.get("itemText");
Object object=item.get("itemImage");
Toast.makeText(MainActivity.this, itemText, 0).show();

//根据图片进行相应的跳转
switch (images[position]) {
case R.drawable.p1:
startActivity(new Intent(MainActivity.this, TestActivity1.class));//启动另一个Activity
finish();//结束此Activity，可回收
break;
case R.drawable.p2:
startActivity(new Intent(MainActivity.this, TestActivity2.class));
finish();
break;
case R.drawable.p3:
startActivity(new Intent(MainActivity.this, TestActivity3.class));
finish();
break;
}

}
}

}

//activity_main.xml布局文件的代码如下：

<?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_grid.xml布局文件代码如下：

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