GridView实现九宫格布局

//1,准备数据源

//4.GridView配置事件监听器(OnItemClickListener)

GridView三个重要属性：

        android:numColumns=""               每一行显示多少列
        android:horizontalSpacing=""        两列之间的间距
        android:verticalSpacing=""          两行之间的间距

下面请看代码示例：

1.两个布局

    >1     GridView空间布局

<RelativeLayout 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=".MainActivity" >

    <!-- 
    
        android:numColumns=""               每一行显示多少列
        android:horizontalSpacing=""        两列之间的间距
        android:verticalSpacing=""          两行之间的间距
    
     -->
    <GridView 
        android:layout_marginTop="10dp"
        android:id="@+id/gridView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:numColumns="3"
        android:horizontalSpacing="10dp"
        android:verticalSpacing="10dp"/>
</RelativeLayout>

>2   Item样式布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:gravity="center"
    android:background="#000">
    
    <ImageView 
        android:id="@+id/img"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:src="@drawable/ic_launcher"/>
    
    <TextView 
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#fff"
        android:text="icon"/>

</LinearLayout>

一个java类：

public class MainActivity extends Activity implements OnItemClickListener{
private GridView mGridView;
private List<Map<String,Object>> dataList;

private int[] icon = {R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher};


private String[] iconName = {"图标1","图标2","图标3","图标4","图标5","图标6","图标7","图标8","图标9","图标10","图标11","图标12"};

private SimpleAdapter adapter;

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

mGridView = (GridView) findViewById(R.id.gridView);

//1,准备数据源
//2，新建适配器
//3.GridView加载适配器
//4.GridView配置事件监听器(OnItemClickListener)
dataList = new ArrayList<Map<String,Object>>();
adapter = new SimpleAdapter(this, getData(), R.layout.item, new String[]{"image","name"}, new int[]{R.id.img,R.id.name});

mGridView.setAdapter(adapter);
mGridView.setOnItemClickListener(this);
}


private List<? extends Map<String, ?>> getData() {
for (int i = 0; i < icon.length; i++) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("image", icon[i]);
map.put("name", iconName[i]);
dataList.add(map);
}

return dataList;

}


@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(this, "您点击了" + iconName[arg2], Toast.LENGTH_LONG).show();
}
}
