import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class FunFactsActivity extends Activity {
Button mShowFactButton;
@Override
public void onCreate(Bundle savedInstanceState) {
// ...
showFactButton = (Button) findViewById(R.id.showFactButton);
// ...
}
}
