GridView，ListView实例

1.建立MyGrid，MyList类

package com.archermind.activity;

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.widget.GridView;
import android.widget.SimpleAdapter;

public class MyGrid extends Activity
{
    GridView gridView = null;
    List<Map<String, Object>> contents = new ArrayList<Map<String, Object>>();

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mygrid);

        gridView = (GridView) findViewById(R.id.grid);
        for (int i = 0; i < 10; i++)
        {
            HashMap<String, Object> map = new HashMap<String, Object>();
            map.put("PIC", R.drawable.pic);
            map.put("TITLE", "test title");
            contents.add(map);
        }
        SimpleAdapter adapter = new SimpleAdapter(this, contents,
                R.layout.griditem, new String[] { "PIC", "TITLE" }, new int[] {
                        R.id.griditem_pic, R.id.griditem_title, });
        
        gridView.setAdapter(adapter);
    }

}



package com.archermind.activity;

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.widget.ListView;
import android.widget.SimpleAdapter;

public class MyList extends Activity
{
    ListView listView = null;
    List<Map<String, Object>> contents = new ArrayList<Map<String, Object>>();

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mylist);

        listView = (ListView) findViewById(R.id.list);
        for (int i = 0; i < 10; i++)
        {
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("PIC", R.drawable.pic);
            map.put("TITLE", "Test Title");
            map.put("CONTENT", "Test Content");
            contents.add(map);
        }
        SimpleAdapter adapter = new SimpleAdapter(this,
                (List<Map<String, Object>>) contents, R.layout.listitem,
                new String[] { "PIC", "TITLE", "CONTENT" }, new int[] {
                        R.id.listitem_pic, R.id.listitem_title,
                        R.id.listitem_content });

        listView.setAdapter(adapter);
    }

}

2.建立4个XML：griditem.xml,listitem.xml,mygrid.xml,mylist.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    
    <ImageView 
        android:id="@+id/griditem_pic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"        
        />
       
       <TextView 
           android:id="@+id/griditem_title"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_gravity="center_horizontal"
           android:text="test"
           />
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    
    <ImageView 
        android:id="@+id/listitem_pic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:src="@drawable/pic" android:adjustViewBounds="true"
        android:padding="2dip"
        />
    <TextView android:id="@+id/listitem_title"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/listitem_pic"
        android:layout_alignParentRight="true" 
        android:layout_alignParentTop="true"
        android:layout_above="@+id/listitem_content"
        android:layout_alignWithParentIfMissing="true" 
        android:gravity="center_vertical"
        android:text="@+id/listitem_title" 
        android:textSize="22px" />
        
    <TextView android:id="@+id/listitem_content"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/listitem_pic"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true" 
        android:singleLine="true"
        android:ellipsize="marquee" 
        android:text="@+id/item_content"
        android:textSize="14px" />
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    
    
    <GridView xmlns:android="http://schemas.android.com/apk/res/android" 
        android:id="@+id/grid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:verticalSpacing="10dp"
        android:horizontalSpacing="10dp"
        android:numColumns="auto_fit"
        android:columnWidth="90dp"
        android:stretchMode="columnWidth"
        >
        
    </GridView>
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    
    <ListView 
        android:id="@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
</LinearLayout>
