页面布局

<? 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= "horizontal">

<ImageView

android :id= "@+id/img"

android :layout_width= "80dp"

android :layout_height= "80dp"

android :layout_margin= "5px" />

<LinearLayout

android :layout_width= "match_parent"

android :layout_height= "match_parent"

android :orientation= "vertical">

<TextView

android :id= "@+id/title"

android :layout_width= "wrap_content"

android :layout_height= "wrap_content"

android :textColor= "#000000"

android :textSize= "100px" />

<TextView

android :id= "@+id/info"

android :layout_width= "wrap_content"

android :layout_height= "wrap_content"

android :textSize= "60px" />

</LinearLayout>

用SimpleAdapter将数据显示在布局上

package com.eson.simpleadapter ;

import android.app.ListActivity ;

import android.os.Bundle ;

import android.widget.SimpleAdapter ;

import java.util.ArrayList ;

import java.util.HashMap ;

import java.util.List ;

import java.util.Map ;

public class MainActivity extends ListActivity {

@Override

protected void onCreate (Bundle savedInstanceState) {

super .onCreate(savedInstanceState) ;

SimpleAdapter simpleAdapter = new SimpleAdapter(this, getData() , R.layout. content_main ,

new String[]{"title" , "info", "img" }, new int []{R.id. title, R.id. info, R.id. img}) ;

setListAdapter(simpleAdapter) ;

}

private List<Map<String ,Object>> getData () {

List<Map<String, Object>> list = new ArrayList<Map<String , Object>>();

Map<String , Object> map = new HashMap<String , Object>() ;

map.put( "title" ,"Clock" ) ;

map.put( "info" ,"My clock on the my phone" ) ;

map.put( "img" ,R.drawable. i1 );

list.add(map) ;
