Android循环ListView之前做个iOS下的，实现起来比较复杂，后来在网上找了一个例子，其实现起来比较容易，思路很好，这个我做个整理

这个类就是个ListView的Adapter没什么特别的。
ListAdapter.java
package com.pactera.infinitescrollview;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
public class ListAdapter extends BaseAdapter{
private List list;
private LayoutInflater mInflater;
public ListAdapter (Context context,List list) {
this.list= list;
this.mInflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
if (list != null) {
//这个内容要是显示内容的3倍
return list.size() * 3;
}
return 0;
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return list.get(arg0 % list.size());
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0 % list.size();
}
@Override
public View getView(int postition, View converView, ViewGroup arg2) {
// TODO Auto-generated method stub
ViewHoler viewHoler = null;
if (converView == null) {
viewHoler = new ViewHoler();
converView = mInflater.inflate(R.layout.adapter_list_layout, null);
viewHoler.tvText = (TextView)converView.findViewById(R.id.adapter_list_layout_tv);
converView.setTag(viewHoler);
}else {
viewHoler = (ViewHoler)converView.getTag();
}
viewHoler.tvText.setText(list.get(postition % list.size()));
return converView;
}
static class ViewHoler{
TextView tvText;
}
}
MainActivity.java
package com.pactera.infinitescrollview;
import java.util.ArrayList;
import java.util.List;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.widget.AbsListView;
import android.widget.ListView;
import android.widget.AbsListView.OnScrollListener;
public class MainActivity extends Activity implements OnScrollListener {
private ListView listView;
private List list;
private ListAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listView1);
list = getList();
adapter = new ListAdapter(this, list);
listView.setAdapter(adapter);
listView.setOnScrollListener(this);
listView.setSelection(list.size());
}
public List getList() {
List list = new ArrayList();
for (int i = 0; iadapter.getCount() - 2) {
listView.setSelection(firstVisibleItem - list.size());
}
}
@Override
public void onScrollStateChanged(AbsListView arg0, int arg1) {
// TODO Auto-generated method stub
}
}
重点在上面的onScroll方法 的if语句
activity_main.xml
adapter_list_layout.xml
