Gridview网格视图

Gridview的关键属性：
GridView是可滚动的网格。一般用来显示多张图片。
     android:horizontalSpacing="5dp" 两列之间的间距是5dp
     android:verticalSpacing="5dp" 两行之间的间距是5dp
     android:stretchMode="spacingWidth" 缩放与列宽大小同步
     android:numColumns="auto_fit" 本来是一行显示几个，现在改为自动分配
Gridview的实现相关：准备几张图片作为你的数据、adapter
Gridview布局剩余的空间会平分掉！！！
onItemclicklistener监听
@override
onItemClick(AdapterView<?> v, View arg1, int arg2, long arg3)
四个参数：
1、AdapterView<?> v
2、View view
3、int postoin、、item的一个下标
4、long  b

补充：

1、android:listSelector="@android:color/transparent"//取消Gridview的点击效果

2、取消Gridview的下拉效果：

//通过重新dispatchTouchEvent方法来禁止滑动@Overridepublic boolean dispatchTouchEvent(MotionEvent ev) {    if(ev.getAction() == MotionEvent.ACTION_MOVE){        return true;//禁止Gridview进行滑动    }    return super.dispatchTouchEvent(ev);}

Gridview的实现代码：

package com.example.gridview;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.Window;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.GridView;import android.widget.SimpleAdapter;import android.widget.Toast;public class MainActivity extends Activity implements OnItemClickListener {private GridView gridView;private SimpleAdapter adapter;private List<Map<String, Object>> dataList;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.main);gridView = (GridView) findViewById(R.id.gridView);dataList = new ArrayList<Map<String, Object>>();adapter = new SimpleAdapter(this, getData(), R.layout.item, new String[] { "pic", "name" },new int[] { R.id.pic, R.id.name });gridView.setAdapter(adapter);gridView.setOnItemClickListener(this);// 监听}private List<Map<String, Object>> getData() {int[] drawable = { 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 };String[] iconName = { "联系人", "日历", "照相机", "时钟", "游戏", "短信", "铃声", "设置", "语音", "天气", "浏览器", "Youtube" };for (int i = 0; i < drawable.length; i++) {Map<String, Object> map = new HashMap<String, Object>();map.put("pic", drawable[i]);map.put("name", iconName[i]);dataList.add(map);}Log.i("Main", "size=" + dataList.size());return dataList;}@Overridepublic void onItemClick(AdapterView<?> v, View view, int postion, long arg3) {// 通过adapter获取数据Toast.makeText(this, "" + postion, 0).show();}}

adpater有一个自定义布局;

 

<?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" >    <ImageView        android:id="@+id/pic"        android:layout_width="60dp"        android:layout_height="60dp"        android:layout_gravity="center"        android:src="@drawable/address_book" />    <TextView        android:id="@+id/name"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_marginTop="5dp"        android:text="名字"        android:textColor="#ffffff" /></LinearLayout>

 

 

还需要一个很简单的布局文件：

<?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:background="#000000"    android:orientation="vertical" >    <GridView        android:id="@+id/gridView"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="15dp"        android:gravity="center_horizontal"        android:horizontalSpacing="10dp"        android:numColumns="3"        android:verticalSpacing="10dp" /></LinearLayout>
