XML File

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
        <!--Keep your layout here-->
        
    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/RLProgress"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#77000000">

        <com.airbnb.lottie.LottieAnimationView
            android:layout_width="match_parent"
            android:layout_height="250dp"
            android:layout_above="@+id/loading_splashscreenText"
            app:lottie_autoPlay="true"
            android:layout_marginBottom="15dp"
            android:id="@+id/lottiLoadingProgress"
            app:lottie_loop="true"/>

        <TextView
            android:id="@+id/loading_splashscreenText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_marginLeft="35dp"
            android:layout_marginRight="35dp"
            android:background="@color/ColorBlack"
            android:padding="5dp"
            android:text="Loading ... "
            android:textColor="@color/color_white"
            android:textSize="16dp" />

    </RelativeLayout>

</FrameLayout>

API Function

           private void callAPI() {
            RLProgress.setVisibility(View.VISIBLE);
            Interface.callAPI("api_url").enqueue(new Callback<Model>() {
                @Override
                public void onResponse(Call<Model> call, Response<Model> response) {
                    RLProgress.setVisibility(View.GONE);
                }
    
                @Override
                public void onFailure(Call<Model> call, Throwable t) {
                    RLProgress.setVisibility(View.GONE);
                }
            });
        }
