（一）概述

（二）相关属性


（三）使用案例

实现效果图：

代码实现：
GirdView中items.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:padding="5dp">    <ImageView        android:id="@+id/img_icon"        android:layout_width="64dp"        android:layout_height="64dp"        android:layout_centerInParent="true"        android:src="@drawable/address_book" />    <TextView        android:id="@+id/txt_icon"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/img_icon"        android:layout_centerHorizontal="true"        android:layout_marginTop="30dp"        android:text="哈哈"        android:textSize="18sp" /></RelativeLayout>

public class Icon {    private int iId;    private String iName;    public Icon() {    }    public Icon(int iId, String iName) {        this.iId = iId;        this.iName = iName;    }    public int getiId() {        return iId;    }    public String getiName() {        return iName;    }    public void setiId(int iId) {        this.iId = iId;    }    public void setiName(String iName) {        this.iName = iName;    }}

MainActivity的布局文件跟java代码：

<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"    android:padding="5dp"    tools:context=".MainActivity">    <!--numColumns设置每行显示多少个-->    <GridView        android:id="@+id/grid_photo"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:numColumns="3" /></RelativeLayout>

public class MainActivity extends Activity {    private Context mContext;    private GridView grid_photo;    private BaseAdapter mAdapter = null;    private ArrayList<Icon> mData = null;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mContext = MainActivity.this;        grid_photo = (GridView) findViewById(R.id.grid_photo);        mData = new ArrayList<Icon>();        mData.add(new Icon(R.drawable.calendar, "图标1"));        mData.add(new Icon(R.drawable.camera, "图标2"));        mData.add(new Icon(R.drawable.clock, "图标3"));        mData.add(new Icon(R.drawable.games_control, "图标4"));        mData.add(new Icon(R.drawable.messenger, "图标5"));        mData.add(new Icon(R.drawable.ringtone, "图标6"));        mData.add(new Icon(R.drawable.settings, "图标7"));        mAdapter = new MyAdapter<Icon>(mData, R.layout.item_grid_icon) {            @Override            public void bindView(ViewHolder holder, Icon obj) {                holder.setImageResource(R.id.img_icon, obj.getiId());                holder.setText(R.id.txt_icon, obj.getiName());            }        };        grid_photo.setAdapter(mAdapter);        grid_photo                .setOnItemClickListener(new AdapterView.OnItemClickListener() {                    @Override                    public void onItemClick(AdapterView<?> parent, View view,                            int position, long id) {                        Toast.makeText(mContext, "你点击了~" + position + "~项",                                Toast.LENGTH_SHORT).show();                    }                });    }}

。
