Hello vamsi,

you need to implements the following interface:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class CallingWebServices extends Activity implements View.OnClickListener{
 
//....
 
   public void onClick(View v){ 
 
      // TODO
 
   }
 
}
Parsed in 0.033 seconds,  using GeSHi 1.0.8.4

or set an anonymous OnClickListener to the Button, like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

Invoke.setOnClickListener(new View.OnClickListener(){
 
   public void onClick(View v){
 
      // TODO
 
   { 
 
});
Parsed in 0.034 seconds,  using GeSHi 1.0.8.4

Hi plusminus,

I have used anonymous onClickListener . But giving error that

" The type new View.OnClickListener(){} must implement the inherited abstract method
View.OnClickListener.onClick(View) "

Is it need to import any new classes? Already i was used statement import android.view.View.OnClickListener;

pls ..
