我有一个Recycler View,其中包含从内部存储加载的图像.我想点击时突出显示所选项目.我尝试了很多东西,但它没有用.实际上我需要的是当我点击Recycler View中的任何项目时,Item必须进入My ArrayList,它也应该突出显示,当我点击或说取消选择时它必须再次变为正常.这是我的代码:

public class Images extends Fragment {
    private List<ImageHolder> imageList;
    Cursor imageCursor;

    RecyclerView recyclerView;
    MyImageAdapter adapter;
    ActionButton clickButton;
    List<String> listofImages;
    List<Integer> pos;
    int columnIndex;
    StringBuilder stringBuilder;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,   Bundle savedInstanceState) {
        View rootlayout = inflater.inflate(R.layout.image, container, false);
        listofImages=new ArrayList<String>();
        pos=new ArrayList<Integer>();
        stringBuilder=new StringBuilder();
        ContentResolver imageResolver = getActivity().getContentResolver();
        Uri imageUri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        String projection[]={MediaStore.Images.Thumbnails._ID,MediaStore.Images.Media.TITLE};
        imageCursor = getActivity().managedQuery(imageUri, projection, null, null, null);

        clickButton= (ActionButton) rootlayout.findViewById(R.id.action_button);

        recyclerView = (RecyclerView) rootlayout.findViewById(R.id.recycler_view_image);
        adapter = new MyImageAdapter(getActivity(), getImageList()); …
