Android programming method to implement infinite loop display of ListView content

This article describes the method of Android programming to implement infinite loop display of ListView content. Share it for your reference, as follows:

In fact, to achieve infinite loop display, the main thing is to implement the class that inherits Adapter.

I'm using BaseAdapter here

private class MyAdapter extends BaseAdapter{
    private Context context;
    private String[] strs = null;
    LayoutInflater inflater = null;
    public MyAdapter(Context context){
       = context;
      //The data displayed in the listview      strs = new String[]{"0","1","2","3","4","5","6","7","8","9"};
      inflater = (context);
    }
    public MyAdapter(){
    }
    @Override
    public int getCount() {
      // TODO Auto-generated method stub
      //Returns the maximum value that int can save, this value is 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 = (, null);
         = (TextView) ();
        (holder);
      }else{
        holder = (ViewHolder) ();
      }
      //strs[position%] implements the loop of data in listview      (strs[position%]);
      return view;
    }
}
class ViewHolder{
    public TextView text;
}

Assign adapter to listview in onCreate method

@Override
public void onCreate(Bundle savedInstanceState) {
    (savedInstanceState);
    setContentView();
    listView = (ListView) findViewById();
    MyAdapter adapter = new MyAdapter(this);
    (adapter);
    (Integer.MAX_VALUE/2+1);
    //Set the default selection after listview is initialized, otherwise the listview can only be dragged upwards but not downwards after listview is initialized.}

In fact, strictly speaking, this program is not an infinite loop, but there is too much data in the listview, reaching more than 2 billion, so it can also be regarded as an infinite loop.
