注意两种方法都要在AndroidManifest.xml中添加上如下配置信息：

Java代码 
<uses-permission android:name="android.permission.RECEIVE_SMS"/> 

3、Android中的ListView使用方法
Java代码 
package cn.edu.ui; 
 
import java.util.ArrayList; 
import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 
 
import android.app.ListActivity; 
import android.os.Bundle; 
import android.widget.SimpleAdapter; 
 
public class Mp3PlayerActivity extends ListActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
      
      List<Map<String,String>> list=new ArrayList<Map<String,String>>(); 
      Map<String,String> map1=new HashMap<String,String>(); 
      map1.put("name", "Hello"); 
      map1.put("size", "1000"); 
      list.add(map1); 
       
      SimpleAdapter simpleAdapter=new SimpleAdapter(this,list,R.layout.mylistview,new String []{"name","size"},new int [] {R.id.name,R.id.size}); 
      setListAdapter(simpleAdapter); 
       
    } 
} 
Xml代码 
<?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" 
    > 
<TextView   
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="@string/hello" 
    />
