怎样使用ListView？

ArrayAdapter的使用

package com.mengmeng.android_listview;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.SimpleAdapter;import android.widget.Toast;public class MainActivity extends Activity implements OnItemClickListener  {	private ListView mListView;	private ArrayAdapter
      
        mArray_Adapter;	private SimpleAdapter mSimpleAdapter;		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				mListView = (ListView) findViewById(R.id.listView);		//载入数据源		String[] str = {"大眼萌1","大眼萌2","大眼萌3","大眼萌4","大眼萌5"};				mArray_Adapter = new ArrayAdapter
       
        (this, android.R.layout.simple_expandable_list_item_1, str);		mListView.setAdapter(mArray_Adapter);				mListView.setOnItemClickListener(this);	}	//监听	@Override	public void onItemClick(AdapterView
         arg0, View arg1, int arg2, long arg3) {		String text = mListView.getItemAtPosition(arg2)+"";		Toast.makeText(this, text, Toast.LENGTH_SHORT).show();	}}
       
      

simpleAdapter的使用

@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				mListView = (ListView) findViewById(R.id.listView);				getData();		mSimpleAdapter = new SimpleAdapter				(this, list, R.layout.list_item, new String[] {"text","image"}, new int[] {R.id.text,R.id.image});		mListView.setAdapter(mSimpleAdapter);		}	private List

使用OnScollListener()  notifyDataSetChanged()
@Overridepublic void onScroll(AbsListView view, int firstVisibleItem,		int visibleItemCount, int totalItemCount) {	// TODO Auto-generated method stub	}@Overridepublic void onScrollStateChanged(AbsListView view, int scrollState) {	if(scrollState == SCROLL_STATE_FLING){//用力划一下		Map
      
        map = new HashMap
       
        ();		map.put("text", "正在加入"+i++);		map.put("image", R.drawable.ic_launcher);		list.add(map);		
        mSimpleAdapter.notifyDataSetChanged();		Toast.makeText(this, "正在滚动...", Toast.LENGTH_SHORT).show();			}else if(scrollState == SCROLL_STATE_IDLE){//停止滚动			}else if(scrollState == SCROLL_STATE_TOUCH_SCROLL){//正在滚动			}
