Android listview handling click event

I have a custom list view implemented with Baseadapter. My dataset includes a string and a flag. I need to control the clickable property of each row in that list view based on this flag.. Any help will be greatly appreciated..

I understand that your dataset is collection of data objects that contains a string and a flag. In that case you can override the isEnabled(int position) in your base adapter like this 

public boolean isEnabled(int position){
    return myDataSet.get(position).getFlag();// returning true here will make that item clickable
}

Note that i am referring to my data object of the corresponding position.

If you want the listview with custom properties try to implement your own customAdapter which extends the BaseAdapter

public class CustomListAdapter extends BaseAdapter {
private  ArrayList<Generics> allElementDetails;

private LayoutInflater mInflater;

public CustomListAdapter(Context context, ArrayList<Generics> results) {
    allElementDetails = results;
    mInflater = LayoutInflater.from(context);

}
public int getCount() {
    return allElementDetails.size();        
}
public Object getItem(int position) {
    return allElementDetails.get(position);
}
public long getItemId(int position) {
    return position;
}
public View getView(int position, View convertView, ViewGroup parent) 
{
    convertView = mInflater.inflate(R.layout.filedialog, null);
    ImageView imageview = (ImageView) convertView.findViewById(R.id.imageview);
    TextView textview = (TextView) convertView.findViewById(R.id.textview);
    if(flag==true)
             convertview.setClickable(true) 
     else
             convertview.setClickable(false); 
    return convertView;
}

}

now use the listview.setOnItemClickListener to apply the actions i.e functionality that will perform when the clickable view clicked.

I think this may help u....

hi subi you could use this below code for setting the clicklistener....

 lv.setAdapter(new ArrayAdapter(ClassName.this)); 
 lv.setOnItemClickListener(new AdapterView.OnItemClickListener() 
 { 
      @Override 
      public void onItemClick(AdapterView arg0, View arg1,int arg2, long arg3) 
      { 
      } 
 });

where the arrayAdapter is your customer class extending baseadapter... Hope this helps...
