good thank you, there is a problem
package com.example.media;

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity & lt; string & gt; extends Activity {

Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_main);



Button btn1 = (Button) findViewById (R.id.button1);
final EditText et = (EditText) findViewById (R.id.editText1);
final EditText et2 = (EditText) findViewById (R.id.editText2);

btn1.setOnClickListener (new OnClickListener () {

Override
public void onClick (View v) {
String User = et.getText () toString ();.
String Pass = et2.getText () toString ();.
if (User == null)
{
new AlertDialog.Builder (this)
.setTitle ("error")
.setMessage ("Please enter your user name")
.setPositiveButton ("OK", null)
.show ();
}
}

});
}
}
