Question

i’m tryng to implement an OnClickListener on some buttons that are repeated in a GridView, but Eclipse give me an error on the btn.setOnClickListener Line.

This is the error:

1 method(s) to implement:
- android.view.View.OnClickListener.onClick()

And This is the code:

package com.example.convert;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.GridView;

public class convert extends Activity {
    //private ListView List;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String [] elenco = {
                "ciao","questo","è","un esempio","Configurazione"
                };

        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,R.layout.oggetto,R.id.testogg,elenco);
        GridView gridview = (GridView) findViewById(R.id.gridview);
        gridview.setAdapter(arrayAdapter);
        Button btn = (Button) (findViewById(R.id.testogg));

        btn.setOnClickListener(new Button.OnClickListener(){

              OnClickListener(View v) {
                  setContentView(R.layout.oggetto);
              }

            });
    }
}

I don’t understand what that mean, i’m new to java.

Thanks!

Remove the Button class from your onClickListener declaration.

    btn.setOnClickListener(new OnClickListener(){
          @Override
          public void onClick(View v) {
              setContentView(R.layout.oggetto);
          }

        });

OnClickListener is a property of a View.
