Android App Development | Lecture#22 | Hive Learners

Hello dear Learners, I hope you all are well. Today we will cover the sign-in page in a new activity. We will create a new Empty Activity in our project and design the sign-in page with a forget password button. So let's start with lecture 22. I hope you will learn something new today. Creating a new activity is very important to add multiple screens to our Android App.

GitHub Link

Use this GitHub project to clone into your directory. It will constantly get updated in the following lecture so you will never miss the latest code. Happy Coding!.

What Should I Learn

• Create a new Empty Activity
• Design Sign-in screen

Assignment

• Create a sign-in activity and layout

Procedure

Firstly, we need to add a new Empty Activity in our project. Follow the screenshot steps to add the activity correctly. Also, set the activity name accordingly.

Set the name of the sign-in activity as shown in this screenshot. Don't add any special character to the name. You can use the same name.

Now open the design activity of the sign-in page by going to this location as shown in the screenshot. Here we design in sign-in page.

On this sign-in page, I use the password toggle and input type password text. This will add the dots when a user typing the password. Here is the activity_sign_in.xml code.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="8dp">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginBottom="5dp"
            android:text="Sign In"
            android:textSize="26sp"
            android:textStyle="bold" />

        <com.google.android.material.textfield.TextInputLayout

            app:boxStrokeWidth="1dp">

            <EditText
                android:id="@+id/signin_email_et"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                tools:ignore="SpeakableTextPresentCheck" />
        </com.google.android.material.textfield.TextInputLayout>

        <com.google.android.material.textfield.TextInputLayout

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:hint="Enter Your Password"
            app:boxStrokeColor="@color/black"
            app:boxStrokeWidth="1dp"
            app:passwordToggleEnabled="true">

            <EditText
                android:id="@+id/signin_pass_et"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textPassword"
                tools:ignore="SpeakableTextPresentCheck,SpeakableTextPresentCheck" />
        </com.google.android.material.textfield.TextInputLayout>


        <com.google.android.material.button.MaterialButton
            android:id="@+id/signin_btn"
            style="@style/Widget.AppCompat.Button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="10dp"
            android:backgroundTint="#2196F3"
            android:text="Sign In"
            android:textColor="@color/white"
            app:cornerRadius="4dp" />

        <com.google.android.material.button.MaterialButton
            android:id="@+id/forget_pass_btn"
            style="@style/Widget.AppCompat.Button.Borderless"
            android:layout_width="wrap_content"
            android:layout_height="35dp"
            android:layout_gravity="right"
            android:background="@null"
            android:text="Forget Password"
            android:textColor="@color/black"
            android:textSize="14sp"
            app:backgroundTint="@null"
            tools:ignore="TouchTargetSizeCheck" />
    </LinearLayout>
</LinearLayout>

Now we also need to declare and initialize the widgets in the sign-up and sign in their java file. Also, implement the button listener.

package com.example.hivelearners2;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

import com.google.android.material.button.MaterialButton;

public class SignIn_Activity extends AppCompatActivity {

    EditText email_et, pass_et;
    MaterialButton signin_btn, forget_pass_btn;


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

        email_et = findViewById(R.id.signin_email_et);
        pass_et = findViewById(R.id.signin_pass_et);
        signin_btn = findViewById(R.id.signin_btn);
        forget_pass_btn = findViewById(R.id.forget_pass_btn);

        signin_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });

        forget_pass_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
    }

}

package com.example.hivelearners2;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.transition.Fade;
import android.transition.Transition;
import android.view.View;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import com.google.android.material.button.MaterialButton;

public class MainActivity extends AppCompatActivity {

    EditText name_et, email_et, pass_et, confirm_pass_et;
    MaterialButton signup_btn, already_act_btn;

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

        name_et = findViewById(R.id.signup_name_et);
        email_et = findViewById(R.id.signup_email_et);
        pass_et = findViewById(R.id.signup_pass_et);
        confirm_pass_et = findViewById(R.id.signup_confirm_pass_et);
        signup_btn = findViewById(R.id.signup_btn);
        already_act_btn = findViewById(R.id.already_act_btn);


        signup_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

        already_act_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });
    }
}

Thank You
