android ListView内容无限循环展示

其实要达到无限循环显示，主要就是实现继承Adapter的类。

我这里用到的是BaseAdapter

private class MyAdapter extends BaseAdapter{    	private Context context;    	private String[] strs = null;    	LayoutInflater inflater = null;    	public MyAdapter(Context context){    		this.context = context;    		//listview中循环显示的数据    		strs = new String[]{"0","1","2","3","4","5","6","7","8","9"};    		inflater = LayoutInflater.from(context);    	}    	public MyAdapter(){    		    	}		@Override		public int getCount() {			// TODO Auto-generated method stub			//返回int可以保存的最大值，此值为2147483647			return Integer.MAX_VALUE;		}		@Override		public Object getItem(int position) {			// TODO Auto-generated method stub			return position;		}		@Override		public long getItemId(int position) {			// TODO Auto-generated method stub			return position;		}		@Override		public View getView(int position, View view, ViewGroup parent) {			// TODO Auto-generated method stub			ViewHolder holder = null;			if(view == null){				holder = new ViewHolder();				view = inflater.inflate(R.layout.textview, null);				holder.text = (TextView) view.findViewById(R.id.text);				view.setTag(holder);			}else{				holder = (ViewHolder) view.getTag();			}			//strs[position%strs.length]实现listview中数据的循环			holder.text.setText(strs[position%strs.length]);						return view;		}    	    }    class ViewHolder{    	public TextView text;    }

在onCreate方法中将adapter赋值给listview

@Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        listView = (ListView) findViewById(R.id.listview);        MyAdapter adapter = new MyAdapter(this);        listView.setAdapter(adapter);        listView.setSelection(Integer.MAX_VALUE/2+1);        //设置listview初始化以后的默认选中项，要不然listview初始化以后只能向上拖动而不能向下拖动。    }

其实，严格来说，此程序并不是无限循环，只不过listview内数据太多，达到20多个亿，所以也可以算作是无限循环。
