This is new Series that I am going to share with you I know the UI design is not good but with the help of this project you will learn new things

1.Open your activity_main.xml file and add this code

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout 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"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".MainActivity">


    <com.google.android.material.navigation.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"/>


    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
        <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:background="@color/white"
            android:fitsSystemWindows="true"
            android:theme="@style/Theme.Convertor"
            android:layout_height="wrap_content">

            <com.google.android.material.appbar.CollapsingToolbarLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:contentScrim="@color/white"
                android:fitsSystemWindows="true"
                app:layout_scrollFlags="scroll|snap|exitUntilCollapsed"
                app:title="img to pdf"
                app:expandedTitleGravity="top"
                app:expandedTitleMarginStart="48dp"
                app:expandedTitleMarginTop="7dp">

            <include
                app:layout_collapseMode="parallax"
                layout="@layout/convertor_toll"/>


                <androidx.appcompat.widget.Toolbar
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    app:layout_collapseMode="pin"
                    app:title="img to pdf"
                    app:navigationIcon="@drawable/ic_baseline_menu_24"/>

            </com.google.android.material.appbar.CollapsingToolbarLayout>

        </com.google.android.material.appbar.AppBarLayout>


        <androidx.core.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior">


            <androidx.recyclerview.widget.RecyclerView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>

        </androidx.core.widget.NestedScrollView>


        <ProgressBar
            android:visibility="gone"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="300dp"/>
        
    </androidx.coordinatorlayout.widget.CoordinatorLayout>

</androidx.drawerlayout.widget.DrawerLayout>

2.create a new layout for open camera or upload image name it like convertor_toll.xml and add this code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize">


    <LinearLayout
        android:id="@+id/convertor_toll_layoutOne"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginHorizontal="16dp">

        <Button
            android:id="@+id/convertor_toll_camera"
            android:layout_width="wrap_content"
            android:layout_height="100dp"
            android:layout_weight="1"
            android:text="Camera" />

        <Space
            android:id="@+id/convertor_toll_space"
            android:layout_width="10dp"
            android:layout_height="match_parent" />

        <Button
            android:id="@+id/convertor_toll_upload"
            android:layout_width="wrap_content"
            android:layout_height="100dp"
            android:layout_weight="1"
            android:text="upload" />

    </LinearLayout>


    <ImageView
        android:id="@+id/convertor_toll_imageView"
        android:layout_width="wrap_content"
        android:layout_height="160dp"
        android:layout_below="@id/convertor_toll_layoutOne"
        android:layout_centerHorizontal="true"
        android:layout_margin="16dp"
        android:scaleType="centerCrop"
        android:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/convertor_toll_fileName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/convertor_toll_imageView"
        android:text="name"
        android:textAlignment="center"
        android:textColor="@color/black"
        android:textSize="18sp"
        android:textStyle="bold" />

    <Button
        android:id="@+id/convertor_toll_convert"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/convertor_toll_fileName"
        android:layout_margin="16dp"
        android:text="convert" />


</RelativeLayout>

        android:layout_height="60dp"
        android:src="@drawable/ic_file" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="file name"
