My Codes : (I don't think you will need code but anyway)

OnCreate()


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        search_bar=findViewById(R.id.toolbar_search_slot);

        toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        MainActivity.this.setTitle(" ");
        getSupportActionBar().setDisplayHomeAsUpEnabled(false);
        getSupportActionBar().setDisplayShowHomeEnabled(false);
        getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_arrow_back_white_24dp);


        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                search_bar.setVisibility(View.GONE);

                getSupportActionBar().setDisplayHomeAsUpEnabled(false);
                getSupportActionBar().setHomeButtonEnabled(false);
            }
        });

checkpermission();

        videogridView=findViewById(R.id.video_grid_view);

Solution

Place a three dot button inside your item_xml file then set OnClickListener to your button and on click of that button do this:

Now create a menu xml file and set it as shown below and it should work pretty well.

 viewHolder.navigicon.setOnClickListener(new View.OnClickListener() {    
        @Override
        public void onClick(View v) {  
            PopupMenu popupMenu = new PopupMenu(mContext,v);
            popupMenu.inflate(R.menu.list_menu);
            popupMenu.show();
        }
    });
