I've four textviews and a button in listview. when user clicks on the button i want to get the value of these four textviews and pass to the database. I'm confuse how to save the data of selected item to sqlite.

public class PlannningListViewAdapter extends BaseAdapter{

Context context;
public ArrayList<Planning> planArraylist;
private static LayoutInflater inflater = null;
public Activity planActivity;

public PlannningListViewAdapter(Context context,
        ArrayList<Planning> planArraylist) {
    this.context = context;
    this.planArraylist = planArraylist;
    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

@Override
public int getCount() {
    return planArraylist.size();
}

@Override
public Object getItem(int arg0) {
    return arg0;
}

@Override
public long getItemId(int arg0) {
    return arg0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.single_lv_item, null);
    }

    Planning p = planArraylist.get(position);

    TextView tvDocCode = (TextView) convertView.findViewById(R.id.Plan_no);
    TextView tvDocName = (TextView) convertView.findViewById(R.id.doc_name);
    TextView tvmon = (TextView) convertView.findViewById(R.id.mon);
    TextView tvAdr = (TextView) convertView.findViewById(R.id.adr);
    Button   btn_save =(Button)convertView.findViewById(R.id.button1);
    btn_save.setOnClickListener(ButtonClickListener);


    tvDocCode.setText(p.getDocCode());
    tvDocName.setText(p.getDocName());
    tvmon.setText(p.getTerrCode());
    tvAdr.setText(p.getAdr());
    return convertView;
}
private OnClickListener ButtonClickListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        final int position = mListView.getPositionForView((View) v.getParent());
       // Log.v(TAG, "item clicked, row %d", position);
    }
};

}
