Android code to add two numbers

hi,

i am an beginner in android. i want to add two numbers in android, working on eclipse and i am getting an error in the code

error:
txtbox1= (EditText) findViewById(R.id.txtbox1);
button1 = (Button) findViewById(R.id.button1);
tv = (TextView) findViewById(R.id.lbl1);
txtbox2= (EditText) findViewById(R.id.txtbox2);

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class fit extends Activity {
    Button button1;
    EditText txtbox1,txtbox2;
    TextView tv;

/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        txtbox1= (EditText) findViewById(R.id.txtbox1);
        button1 = (Button) findViewById(R.id.button1);
        tv = (TextView) findViewById(R.id.lbl1);
        txtbox2= (EditText) findViewById(R.id.txtbox2);
        button1.setOnClickListener(new clicker());
    }
    class clicker implements Button.OnClickListener
    {
        public void onClick(View v)
        {
            String a,b;
            Integer vis;
            a = txtbox1.getText().toString();
            b = txtbox2.getText().toString();
            vis = Integer.parseInt(a)+Integer.parseInt(b);
            tv.setText(vis.toString());
        }
    }
}

can we correct the error and make the code run?

Are you going to tell us what the error is, or are we supposed to guess? Is it that "R.id" does not exist? Maybe this helps: http://stackoverflow.com/questions/3721950/android-helloviews-spinner-tutorial-r-id-and-r-array-can-not-be-resolved

Deepika, I've added code tags and indentation for you this time. You can do so yourself by using the Code button when writing your post.
