GridView用于在界面上按照行列分布的方式显示多个组件

在layout中布局两个文件

一个是需要布局的样式一个是gridview

其中

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

配置文件中

android:theme="@android:style/Theme.Black.NoTitleBar"

public class MainActivity extends Activity implements AdapterView.OnItemClickListener {    private GridView gridView;    private List<Map<String,Object>>datalist;    private int[]icon={R.drawable.address_book,R.drawable.calendar,R.drawable.camera,R.drawable.clock,R.drawable.games_control,R.drawable.messenger,R.drawable.settings,R.drawable.speech_balloon,R.drawable.youtube,R.drawable.world,R.drawable.ringtone,R.drawable.weather};    private  String[]iconName={"通讯录","日历","照相","闹钟","游戏","短信","设置","语音","视频","浏览器","铃声","天气"};    private SimpleAdapter adapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        gridView =(GridView)findViewById(R.id.gridView);        //1准备数据源，        //2新建适配器 simpleAdapter        //3加载适配器        //4配置监听        datalist = new ArrayList<Map<String, Object>>();       // getDate();        adapter = new SimpleAdapter(this,getDate(),R.layout.item,new String[]{"imag","text"},new int[]{R.id.imag,R.id.textView});        gridView.setAdapter(adapter);        gridView.setOnItemClickListener(this);    }    private List<Map<String,Object>> getDate(){        for(int i=0;i<icon.length;i++){            Map<String,Object>map=new HashMap<String, Object>();            map.put("imag",icon[i]);            map.put("text",iconName[i]);            datalist.add(map);        }    return datalist;    }    @Override    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {    }}
