我可以在多个地方使用相同的片段吗？

Question

I create a lot of the same fragments. They have the same shape. Can I delete all of them and use just one in more than place if I relied on position like this?

 ViewPager pager = getView().findViewById( R.id.pager_saraya );

        for(int i=0 ; i<data.size() ; i++)
        {
            if(data.get( i ).getImage() == R.drawable.food_1)
            {
                ArrayList<Integer> det=new ArrayList<>(  );

                for( int j=1 ;j<=7;j++)
                {

                    int photoId= getResources().getIdentifier( "makdoos_"+i,"drawable" ,getContext().getPackageName() );

                    det.add(photoId);
                }

                det.add( R.drawable.seha );
                ImageAdapter_details adapter_makdoos = new ImageAdapter_details( getContext(), det );
                pager.setAdapter( adapter_makdoos );
            }

            else if(data.get( i ).getImage() == R.drawable.food_2)
            {

                ArrayList<Integer> det=new ArrayList<>(  );

                for( int j=1 ;j<=10;j++)
                {

                    int photoId= getResources().getIdentifier( "fish"+i,"drawable" ,getContext().getPackageName() );

                    det.add(photoId);
                }

                det.add( R.drawable.seha );
                ImageAdapter_details adapter_makdoos = new ImageAdapter_details( getContext(), det );
                pager.setAdapter( adapter_makdoos );
            }
        }

Answer to your question if you can move common code to one place and use it where it is needed is Yes you can do it and is a good idea. Follow the principle of DRY

• D Do not
• R repeat
• Y yourself

You can move the common code to a helper or a util class name it that fits your standards. Make it static or non static and it is ready to be used.
