<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"

</GridView>

GirdView的一些屬性：

android:numColumns="auto_fit" --------列數(shù)設(shè)置為自動(dòng)
android:columnWidth="90dp"，----------每列的寬度，也就是Item的寬度
android:stretchMode="columnWidth"------縮放與列寬大小同步
android:verticalSpacing="10dp"----------垂直邊距
android:horizontalSpacing="10dp"-------水平邊距

1、準(zhǔn)備數(shù)據(jù)源

2、新建適配器

3、加載適配器

GridView(網(wǎng)格視圖)是按照行列的方式來顯示內(nèi)容的，一般用于顯示圖片，圖片等內(nèi)容，比如實(shí)現(xiàn)九宮格圖，用GridView是首選，也是最簡(jiǎn)單的，下面來個(gè)實(shí)例，

實(shí)例下載：demo

效果圖：

MainActivity.java

package com.example.testgridview;

import java.util.ArrayList;

import java.util.List;

public class MainActivity extends Activity {

  // 圖片封裝為一個(gè)數(shù)組
  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.ringtone, R.drawable.settings,
      R.drawable.speech_balloon, R.drawable.weather, R.drawable.world,
      R.drawable.youtube };
  private String[] iconName = { "通訊錄", "日歷", "照相機(jī)", "時(shí)鐘", "游戲", "短信", "鈴聲",
      "設(shè)置", "語音", "天氣", "瀏覽器", "視頻" };

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);
    gview = (GridView) findViewById(R.id.gview);
    //新建List
    data_list = new ArrayList<Map<String, Object>>();
    //獲取數(shù)據(jù)
    getData();
    //新建適配器
    String [] from ={"image","text"};
    int [] to = {R.id.image,R.id.text};
    sim_adapter = new SimpleAdapter(this, data_list, R.layout.item, from, to);
    //配置適配器
    gview.setAdapter(sim_adapter);
  }

  
  
  public List<Map<String, Object>> getData(){    
    //cion和iconName的長(zhǎng)度是相同的，這里任選其一都可以
    for(int i=0;i<icon.length;i++){
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("image", icon[i]);
      map.put("text", iconName[i]);
      data_list.add(map);
    }
      
    return data_list;
  }
