Kindly have a look and guide me

public class Administrator_Work extends Activity{
@Override
protected void onCreate(Bundle adminkakaam) {
// TODO Auto-generated method stub
super.onCreate(adminkakaam);
setContentView(R.layout.administrator);
Toast.makeText(this, "Logged in as Administrator!",Toast.LENGTH_LONG).show();
final EditText new_user = (EditText) findViewById(R.id.editText1);
final EditText new_pass = (EditText) findViewById(R.id.textView2);
Button add_emp = (Button)findViewById(R.id.addemployee);
final Button create_acc = (Button) findViewById(R.id.creat_acc);
add_emp.setOnClickListener(new OnClickListener() {

setContentView(R.layout.add_employee);
create_acc.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//DatabaseHelper accessing_db = new DatabaseHelper(Administrator_Work.this);
//accessing_db.insert_new_user(new_user.getText().toString(), new_pass.getText().toString());
