import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;

public class MySimpleAdapter extends BaseAdapter{
    private LayoutInflater mInflater;
    private List<Map<String,Object>> list;
    private int layoutID;
    private String flag[];
    private int Items[];
	
    public MySimpleAdapter(Context context,List<Map<String, Object>>list,int layoutID,String flag[],int ItemIDs[]){
    	this.mInflater=LayoutInflater.from(context);//實例化 context 
    	this.list=list;
    	this.layoutID=layoutID;
    	this.flag=flag;
    	this.Items=ItemIDs;
    }
	
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return list.size();
	}

	@Override
	public Object getItem(int position) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return 0;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		// TODO Auto-generated method stub
		convertView =mInflater.inflate(layoutID, null);//填充佈局；
		for(int i=0;i<flag.length;i++){

				}
			});
		
		return convertView;	 
	}
}

Activity 代碼：

 

package com.example.Listdeamon;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ListView;


public class MainActivity extends Activity{
    private MySimpleAdapter sp;
    private ListView listView;
    private List<Map<String, Object>> list;
    private String[] str={"item_imageview","item_bigtv","item_smalltv"};
    private int[] intager={R.id.imv,R.id.bigtv,R.id.smalltv};
   
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		list=new ArrayList<Map<String,Object>>();
		listView=new ListView(this);
		
		 Map<String, Object> map=new HashMap<String, Object>();
		 map.put("item_imageview", R.drawable.ic_launcher);
		 map.put("item_bigtv", "BIGTV");
		 map.put("item_smalltv", "SMALLTV");
		 
		 list.add(map);
		 sp=new MySimpleAdapter(this, list, R.layout.activity_main,str, intager);
		 
		 listView.setAdapter(sp);
		 setContentView(listView);		
	}
	


	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}
 
   
}

Xml 代碼：

 

<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"
    tools:context=".MainActivity" >
  <ImageView android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:id="@+id/imv"/>
    <LinearLayout android:orientation="vertical"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content">
        
      <TextView 
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:textSize="20sp"
       android:id="@+id/bigtv"/>
      <TextView 
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:textSize="20sp"
       android:id="@+id/smalltv"/>
    </LinearLayout>
 <Button 
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="button"
     android:id="@+id/btn"/>
 <CheckBox android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/cb"/>

</LinearLayout>
