Why is this Google + basic sharing not working?

Question

import android.content.Intent;
import android.net.Uri;

import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    Button shareButton = (Button) findViewById(R.id.share_button);
    shareButton.setOnClickListener( 

        new OnClickListener() {

            public void onClick (View v) {
                // Launch the Google+ share dialog with attribution to your app.
                Intent shareIntent = new PlusShare.Builder(this)
                    .setType("text/plain")
                    .setText("Welcome to the Google+ platform.")
                    .setContentUrl(Uri.parse("https://developers.google.com/+/"))
                    .getIntent();

                startActivityForResult(shareIntent, 0);
            }
        }
    );
}

I'm getting an Error on the "OnClickListener" and the "(View V)", also I am near a complete beginnner to Java and Android trying to add some basic Google plus sharing so please help me out

You can't call methods inside the class block, you have to do it in a method.

public class MainActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState){
        Button shareButton = (Button) findViewById(R.id.share_button);
        shareButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick (View v){
                //your code
            }
        });
    }
}
