<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="15dp"
        android:text="@string/loginform"
        android:textSize="40dp" />

    <TextView
        android:id="@+id/textView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="41dp"
        android:text="@string/username" />

    <EditText
        android:id="@+id/uname"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textView3"
        android:layout_alignBottom="@+id/textView3"
        android:layout_alignParentRight="true"
        android:layout_marginRight="14dp"
        android:ems="10"
        android:hint="@string/enter_username" >
     
        <requestFocus />
 
        </EditText>
    <EditText
        android:id="@+id/password"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/uname"
        android:layout_alignRight="@+id/uname"
        android:layout_below="@+id/uname"
        android:layout_marginTop="17dp"
        android:ems="10"
        android:hint="@string/enter_password"
        android:inputType="textPassword" >

     
    </EditText>

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/password"
        android:layout_alignBottom="@+id/password"
        android:layout_alignParentLeft="true"
        android:text="@string/password" />

    <Button
        android:id="@+id/btnlogin"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:enabled="false"
        android:text="@string/login" />

</RelativeLayout>

Step 3: Edit MainActivity.java file from src/package/ folder in your project

package com.example.loginuri;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.support.v4.app.NavUtils;
import android.text.Editable;
import android.text.TextWatcher;

a public class MainActivity extends Activity implements OnClickListener,TextWatcher
{

Button login;
EditText uname;
EditText pwd;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        login = (Button)findViewById(R.id.btnlogin);
        uname = (EditText)findViewById(R.id.uname);
        pwd = (EditText)findViewById(R.id.password);
     
        login.setOnClickListener(this);
        uname.addTextChangedListener(this);
        pwd.addTextChangedListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

@Override
public void afterTextChanged(Editable arg0)
{
if(uname.getText().toString().equalsIgnoreCase("sahin") && pwd.getText().toString().equalsIgnoreCase("raj"))
{
login.setEnabled(true);
}

}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub

}

@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub

}

@Override
public void onClick(View arg0)
{
Intent i = new Intent("android.intent.action.VIEW",Uri.parse("http://licamca.blogspot.com"));
startActivity(i);
}

 
}
