Android Question

setContentView(R.layout.Main); Main cannot be resolved or is not a field

This is a simple program for beginning (simple for you, not for me) eclipse. I want to change a text by clicking on a button, but it's not working.

Here is the code:

package com.example.androidcourse;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.R.layout;

public class MainActivity extends Activity {

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


Button btn = (Button) findViewById(R.id.but_action);
final TextView text = (TextView) findViewById(R.id.txt_caption);
btn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
text.setText("New bingo...");
}
});
}
}

Answer

First just build your project. If it will not work, then delete from imports android.R.layout and use layout from your package.
