Hi, im new to Android programing

I build a listview showing station names, that grabs its data from a URL.

I used ArrayAdapter to accomplish listview with data.

I need to navigate through station names in listview, using previous, next buttons click.

I google for this task and tried in different ways to workout bt im not able to solve.

shall any one pls help me out for this issue.

Thanks in advance......

I tried like this

` private ListView stationList; . . public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.playscreen);

        // move up event handler
        preButton= (ImageButton) findViewById(R.id.prevButton);

        preButton.setOnClickListener(new View.OnClickListener() {
           public void onClick(View view) {
               movePre();
           }
        });

        // move down event handler
        nxtButton= (ImageButton) findViewById(R.id.nextButton);
        nxtButton.setOnClickListener(new View.OnClickListener() {
           public void onClick(View view) {
               moveNxt();
           }
        });



        stationList.setAdapter(new StationAdapter(this,
                android.R.layout.simple_list_item_1, _stationList));

    } else {
        Log.d(TAG, "No Stations");
    }

}

private void movePre(){

     stationList.setSelection(stationList.getSelectedItemPosition() + 1);

}

// Move selected item "down" in the ViewList.
private void moveNxt(){
    stationList.setSelection(stationList.getSelectedItemPosition() + 1);
}

private class StationAdapter extends ArrayAdapter {

    private Vector<Station> items;

    public StationAdapter(Context context, int textViewResourceId,
            Vector<Station> items) {
        super(context, textViewResourceId, items);
        this.items = items;
    }

    public void setSelectedPosition(int pos){
        selectedPos = pos;
        // inform the view of this change
        notifyDataSetChanged();
    }

    public int getSelectedPosition(){
        return selectedPos;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.row, null);
        }
        Station st = items.get(position);
        if (st != null) {
            TextView tt = (TextView) v.findViewById(R.id.toptext);
            TextView bt = (TextView) v.findViewById(R.id.bottomtext);
            if (tt != null) {
                tt.setText(st.getStationName());
            }
            if (bt != null) {
                bt.setText(st.getCT());
            }
        }

        return v;
    }


}
