如何在Android中利用ListView实现一个内容无限循环显示效果-创新互联

这期内容当中小编将会给大家带来有关如何在Android中利用ListView实现一个内容无限循环显示效果，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

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;
}
