Android的网格布局设计简单实例--GridView

1 只有两部分，一个主代码，一个布局，其中，主代码包含了Adapter，里面封装了信息

package com.example.c;import java.util.*;import android.app.Activity;import android.os.Bundle;import android.widget.GridView;import android.widget.ImageSwitcher;import android.widget.SimpleAdapter; public class MainActivity extends Activity {private static final String TAG="==GrazyIt.org==";int [] imageIds=new int[]{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,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher,R.drawable.ic_launcher};    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        List<Map<String,Object>> listItems=new ArrayList<Map<String,Object>>();        for(int i=0;i<imageIds.length;i++){        Map<String,Object> listItem=new HashMap<String,Object>();        listItem.put("image", imageIds[i]);        listItems.add(listItem);        }       // final ImageSwitcher switcher=(ImageSwitcher)findViewById(R.id.)                SimpleAdapter simpleAdapter=new SimpleAdapter(        this,        listItems,        R.layout.activity_main,        new String[]{"image"},        new int[]{R.id.image01});        GridView grid=(GridView)findViewById(R.id.grid01);        grid.setAdapter(simpleAdapter);            }}

3 布局

<LinearLayout 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:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"   android:orientation="vertical"    tools:context=".MainActivity" >      <GridView        android:id="@+id/grid01"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:horizontalSpacing="0pt"        android:verticalSpacing="2pt"        android:numColumns="4"        android:gravity="center"        />    <ImageView         android:id="@+id/image01"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        /></LinearLayout>
