ViewPagerActivity.java 

package com.mw.app.view.activity;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleAdapter;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.viewpager.widget.ViewPager;

import com.mw.app.R;
import com.mw.app.view.element.ViewPagerAdapter;

import java.util.LinkedList;
import java.util.List;

public class ViewPagerActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.view_pager_layout);
        ViewPager viewPager = findViewById(R.id.view_paper_layout_page);
        List views = new LinkedList<>();
        View view1 = LayoutInflater.from(this).inflate(R.layout.grid_layout,null);
        View view2 = LayoutInflater.from(this).inflate(R.layout.radio_layout,null);
        View view3 = LayoutInflater.from(this).inflate(R.layout.component_display_layout,null);
        views.add(view1);
        views.add(view2);
        views.add(view3);
        ViewPagerAdapter adapter = new ViewPagerAdapter(views);
        viewPager.setAdapter(adapter);

    }
}

ViewPagerAdapter.java

package com.mw.app.view.element;

import android.view.View;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.viewpager.widget.PagerAdapter;

import java.util.List;

public class ViewPagerAdapter extends PagerAdapter {
    private List list;

    public ViewPagerAdapter(List list) {
        this.list = list;
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
        return view == object;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
       View view =  list.get(position);
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
       // super.destroyItem(container, position, object);
        container.removeView(list.get(position));
    }
}
