Login page android design

How to Create User Interface Login & Register with Android Studio

ok, this is my first article in Medium. In this section, I want to share with you about the User Interface on Android and we will create a Login page and a Register page. Some components that I will use:
1. Viewpager
2. Fragment
3. Edittext
4. Button
5. Textview
6. Imageview

What about the results? let’s coding (follow step by step)

1. Of course we must already have an Android Studio. if not, you can download it first on the official Android Studio website. If you already have one, please open your Android studio.

2. We create a new project by clicking “Start a new Android Studio project”. Fill in the application name column with “LoginApp”, then click next.

3. Select the minimum SDK you need or want, then click next.

4. Select “Empty Activity” and click next. After that, the “Activity Name” and “Layout Name” columns will appear, in this section just leave it like that, then click finish.

After you click finish, Android Studio will make you an Application with the name “LoginApp”.

After the application is successfully built, you can simply make adjustments to the following sections:

Open the colors.xml file in app/res/values/colors.xml, and change it like this:

Create a folder with the name “font” in the res folder, by right clicking on the res directory, select new / directory and name it “font”. After that, copy this font into font directory. (download the font 1 and font 2).

Create some Drawable Resource File in the drawable directory, by right-clicking on the drawable directory, select new / Drawable Resource File.

After that open file styles.xml and change like this :

Add the theme property in the Main Activity in the manifest, in the app / manifests / AndroidManifest.xml folder

So the AndroidManifest.xml file will be as follows:

After all the steps above are done, then make 2 fragments with the name fragment_login and fragment_register in the layout directory, by right-clicking on the layout directory, New/Fragment/Fragment (Blank)

Uncheck:
include fragment factory methods? and include interface methods?

Adjustment of several layouts :

change the activity_main.xml layout, fragment_login.xml and fragment_register.xml so that it will be as below

Open the strings.xml file in the res / values / strings.xml directory and change it to something like the following :

So that the overall structure of the project will be as follows :

Connect fragments with viewpager

Create an inner class in the MainActivity.java class with the name AuthenticationPapterAdapter. This class is a derivative of the FragmentPagerAdapter class and serves to connect Fragments with ViewPager,

Then call the class in the onCreate() method in MainActivity.java and connect with viewpager

So the MainActivity.java class will be like this

The display of the final application will be like this

Android Material Design Login Form XML UI Design

In this tutorial, I am going to show how to create material design login form XML UI design. Many android applications have login and registration system. Here I have used only XML to create login screen. You have to create a drawable XML file for profile picture background color to make rounded. And you can use icons according to your wish here I have not provided icons. For EditText field icon should be small (24*24) to make attractive.

Android Example: Android Material Design Login Form XML UI Design

Let’s start by creating new android project with the project name Android Material Design Login Form or some else.

Import Design Support Library

In this project I have used TextInputLayout which is available in android design support library, so you have to add design support library in build.gradle file if not have.

XML Layout File

In XML layout file I have used RelativeLayout, LinearLayout, TextInputLayout, EditText, Button, ImageButton and TextView with different xml attribute to make material design login form UI design. Following is the complete content of XML layout file.

XML Drawable File

Create a new XML file in res/drawable to make rounded in profile picture background. Following is the complete content of user_profile_image_background.xml file.

Java Activity File

Default code of java activity file will look like this.

Android Login and Registration Screen Design

To allow only registered users to our android application, we need to implement login and registration screens to ask the users to register first, then login to the application to get an access for the content in an application.

Now we will see how to implement login and registration screens using material design in android application like as shown following.

Android Login and Registration Screens Example

Following is the example of creating the login and registration screens in android application to allow only valid users based on our requirements.

Create a new android application using android studio and give names as LoginExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App.

Once we create an application, open activity_main.xml file from \res\layout folder path and write the code like as shown below.

activity_main.xml

xml version= «1.0» encoding= «utf-8» ?>
LinearLayout xmlns: android = «http://schemas.android.com/apk/res/android»
android :orientation= «vertical» android :layout_width= «match_parent»
android :layout_height= «match_parent» >
TextView
android :id= «@+id/loginscrn»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginTop= «80dp»
android :text= «Login»
android :textSize= «25dp»
android :textStyle= «bold»
android :layout_gravity= «center»/>
TextView
android :id= «@+id/fstTxt»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :layout_marginTop= «20dp»
android :text= «Email»/>
EditText
android :id= «@+id/txtEmail»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :ems= «10»/>
TextView
android :id= «@+id/secTxt»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :text= «Password»
android :layout_marginLeft= «100dp»/>
EditText
android :id= «@+id/txtPwd»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :inputType= «textPassword»
android :ems= «10»/>
Button
android :id= «@+id/btnLogin»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :text= «Login»/>
TextView android :id= «@+id/lnkRegister»
android :layout_width= «match_parent»
android :layout_height= «wrap_content»
android :layout_marginTop= «40dp»
android :text= «New to Tutlane? Register here»
android :gravity= «center»
android :textSize= «20dp»
android :textColor= «#3F51B5»/>
LinearLayout >

Now we will create another layout resource file registration.xml in \res\layout path to allow new users to register in our application for that right click on your layout folder à Go to New à select Layout Resource File and give name as registration.xml.

Once we create a new layout resource file registration.xml, open it and write the code like as shown below

registration.xml

xml version= «1.0» encoding= «utf-8» ?>
LinearLayout xmlns: android = «http://schemas.android.com/apk/res/android»
android :orientation= «vertical» android :layout_width= «match_parent»
android :layout_height= «match_parent» >
TextView
android :id= «@+id/loginscrn»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginTop= «80dp»
android :text= «Registration»
android :textSize= «25dp»
android :textStyle= «bold»
android :layout_gravity= «center»/>
TextView
android :id= «@+id/fstTxt»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :layout_marginTop= «20dp»
android :text= «Full Name»/>
EditText
android :id= «@+id/txtName»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :ems= «10»/>
TextView
android :id= «@+id/secTxt»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :text= «Email»
android :layout_marginLeft= «100dp»/>
EditText
android :id= «@+id/txtEmail»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :ems= «10»/>
TextView
android :id= «@+id/thirdTxt»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :text= «Password»
android :layout_marginLeft= «100dp»/>
EditText
android :id= «@+id/txtPwd»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :inputType= «textPassword»
android :ems= «10»/>
Button
android :id= «@+id/btnLogin»
android :layout_width= «wrap_content»
android :layout_height= «wrap_content»
android :layout_marginLeft= «100dp»
android :text= «Login»/>
TextView android :id= «@+id/lnkLogin»
android :layout_width= «match_parent»
android :layout_height= «wrap_content»
android :layout_marginTop= «40dp»
android :text= «Already Registered? Login here»
android :gravity= «center»
android :textSize= «20dp»
android :textColor= «#3F51B5»
android :onClick= «test»/>
LinearLayout >

Now open your main activity file MainActivity.java from \java\com.tutlane.loginexample path and write the code like as shown below

MainActivity.java

package com.tutlane.loginexample;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.method.LinkMovementMethod;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity <

@Override
protected void onCreate(Bundle savedInstanceState) <
super .onCreate(savedInstanceState);
setContentView(R.layout. activity_main );
TextView register = (TextView)findViewById(R.id. lnkRegister );
register.setMovementMethod(LinkMovementMethod.getInstance());
register.setOnClickListener( new View.OnClickListener() <
@Override
public void onClick(View v) <
Intent intent = new Intent(MainActivity. this , RegistrationActivity. class );
startActivity(intent);
>
>);
>
>

If you observe the above code, whenever the user click on register link, we are redirecting the user from login screen to registration screen using “RegistrationActivity” for that create another activity file RegistrationActivity.java in \java\com.tutlane.loginexample path.

Now right click on your application folder à Go to New à select Java Class and give name as RegistrationActivity.java.

Once we create a new activity file RegistrationActivity.java, open it and write the code like as shown below

RegistrationActivity.java

package com.tutlane.loginexample;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.method.LinkMovementMethod;
import android.view.View;
import android.widget.TextView;

/**
* Created by tutlane on 08-01-2018.
*/

public class RegistrationActivity extends AppCompatActivity <
@Override
protected void onCreate(Bundle savedInstanceState) <
super .onCreate(savedInstanceState);
setContentView(R.layout. registration );
TextView login = (TextView)findViewById(R.id. lnkLogin );
login.setMovementMethod(LinkMovementMethod.getInstance());
login.setOnClickListener( new View.OnClickListener() <
@Override
public void onClick(View v) <
Intent intent = new Intent(RegistrationActivity. this , MainActivity. class );
startActivity(intent);
>
>);
>
>

Now we need to add this newly created activity in AndroidManifest.xml file in like as shown below.

AndroidManifest.xml

xml version= «1.0» encoding= «utf-8» ?>
manifest xmlns: android = «http://schemas.android.com/apk/res/android»
package= «com.tutlane.loginexample» >
application
android :allowBackup= «true»
android :icon= «@mipmap/ic_launcher»
android :label= «@string/app_name»
android :roundIcon= «@mipmap/ic_launcher_round»
android :supportsRtl= «true»
android :theme= «@style/AppTheme» >
activity android :name= «.MainActivity» >
intent-filter >
action android :name= «android.intent.action.MAIN»/>
category android :name= «android.intent.category.LAUNCHER»/>
intent-filter >
activity >
activity android :name= «.RegistrationActivity» android :label= «Registration» > activity >
application >
manifest >

If you observe above example, we created login and registration screens and added all the activities in AndroidManifest.xml file.

Output of Android Login & Registration Screens Example

When we run the above example in the android emulator we will get a result like as shown below.

If you observe above result, initially we are getting a login screen and redirecting the user to the registration screen whenever the user clicks Register Here link.

This is how we can create login and registration screens using material design in android applications to allow valid users based on our requirements.
