How to Create the dynamic Fragment in Android Studio.

 JSON Data Example:-

{
  "menu": [
    {
      "cat_id": "246",
      "cat_name": "A",
      "description": ""    },
    {
      "cat_id": "174",
      "cat_name": "B ",
      "description": ""    },
    {
      "cat_id": "35",
      "cat_name": "C ",
      "description": ""    },
    {
      "cat_id": "37",
      "cat_name": "D ",
      "description": ""    }
  ]
}

 // Make the Xml file here.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <android.support.design.widget.TabLayout
        android:id="@+id/htab_tabs"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:layout_gravity="bottom"
        android:background="#fff"
        app:tabGravity="fill"
        app:tabMode="scrollable"
        app:tabIndicatorColor="@android:color/black" />

    <android.support.v4.view.ViewPager
        android:id="@+id/htab_viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
</LinearLayout>
