In a Previous Tutorial, I have learned How To Get Data using Volley Library In the android app but now we Are Learning how to post Data on the server Using the volley Library in the android app.

lets now Start.

first making the MainActivity.xml file in our project like this

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:background="@color/Backgcolor"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    tools:context=".Registation">



        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginRight="50dp"
            android:layout_marginLeft="50dp"
            android:layout_gravity="center_vertical"
            android:gravity="center"
            android:orientation="vertical"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">



            <EditText

                android:id="@+id/Et_Name"

                android:textAllCaps="false"/>

        </LinearLayout>

    </ScrollView>

Note : volley Library SinglationClass and Dependancies copy our previous tutrial 

now make MainActivity.java Class In our project.
