Add Row to EfficiencyAdapter

Postby guruk » Wed Mar 18, 2009 4:13 pm

i have a Efficiency Adapter with extra Rows and Holders.

How would I ADD just a new row when I keep the List in the beginning clean.
Or how do I have to initialize this Adapter empty. Short Tut or demo would be great

Just important I like a listview, with rows that have pic and text and i like to add
, delete, change items

here is my code till now

private static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;

public EfficientAdapter(Context context) {

mInflater = LayoutInflater.from(context);


public void add(String string)
// TODO Auto-generated method stub


* The number of items in the list is determined by the number of speeches
* in our array.
* @see android.widget.ListAdapter#getCount()
public int getCount() {
return 0;
//return mStrings.length;

public void setSelected(int index) {
// notify the model that the data has changed, need to update the view

* Since the data comes from an array, just returning the index is
* sufficent to get at the data. If we were using a more complex data
* structure, we would return whatever object represents one row in the
* list.
* @see android.widget.ListAdapter#getItem(int)
public Object getItem(int position) {
return position;

* Use the array index as a unique id.
* @see android.widget.ListAdapter#getItemId(int)
public long getItemId(int position) {
return position;

* Make a view to hold each row.
* @see android.widget.ListAdapter#getView(int, android.view.View,
* android.view.ViewGroup)
public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder holder;

if (convertView == null) {
convertView = mInflater.inflate(R.layout.row, null);

holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(;
holder.text2 = (TextView) convertView.findViewById(;
holder.icon = (ImageView) convertView.findViewById(;

} else {

holder = (ViewHolder) convertView.getTag();

// Bind the data efficiently with the holder.


return convertView;

static class ViewHolder {
TextView text;
TextView text2;
ImageView icon;
