Android Recycleview Item 点击选择事件以及选中后标记不同背景色滑动不出现错乱

实现recycleview使用基本流程,点击事件,长按事件,item选择后有特殊标记其余item恢复原状,滑动不出现错乱问题。伪代码如下:

 

Activity代码

public class VideoOnDemandActivity extends Activity {

    private RecyclerView mVieoRecycleview;
    private TitileBarView dateTimeView;
    private SuspectInfoModel suspectInfo;
    private VideoListAdapter videoListAdapter;
    private ArrayList mVideoList;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_on_demand);
        suspectInfo = SuspectInfoStore.getInstance().suspectInfo;
        initView();

    }

    private void initView() {
        mVideoList = new ArrayList<>();
        mVieoRecycleview = findViewById(R.id.video_recycleview);
        mVieoRecycleview.setHasFixedSize(true);
        mVieoRecycleview.setLayoutManager(new LinearLayoutManager(this));
        dateTimeView = (TitileBarView) findViewById(R.id.dateTimeView);
        if (suspectInfo != null) {
            dateTimeView.setType("登陆用户:");
            dateTimeView.setUserName(suspectInfo.getXM());
            dateTimeView.setTitle("视频点播");

            videoListAdapter = new VideoListAdapter(this,mVideoList,"");
             mVieoRecycleview.setAdapter(videoListAdapter);

            videoListAdapter.setmOnItemClickListener(new VideoListAdapter.OnItemClickListener() {
                @Override
                public void onItemClick(View view, int position, ArrayList msg) {
                    Toast.makeText(VideoOnDemandActivity.this, "点击了"+position, Toast.LENGTH_SHORT).show();
                    Log.e("---电视节目---点击",position+"");
                }

                @Override
                public void onItemLongClick(View view, int position) {
                    Toast.makeText(VideoOnDemandActivity.this, "长恩了"+position, Toast.LENGTH_SHORT).show();
                    Log.e("---电视节目---长摁",position+"");
                }
            });
    }
}}

 

 

Bean代码:

public class VideoListBean {

    private String Id = "";
    private String Img = "";
    private String Name = "";
    private int imageId;
    private String selectTag = "";
    private int selectNum = 1;


    public VideoListBean(JSONObject item) {

        this.Id = item.optString("Id");
        this.Img = item.optString("Img");
        this.Name = item.optString("Name");
        this.imageId = item.optInt("imageId");
        this.selectTag = item.optString("selectTag");
        this.selectNum = item.optInt("selectNum");
    }

    public VideoListBean(String name, int imageId) {

       this.Name = name;
       this.imageId = imageId;
    }

    public String getId() {
        return Id;
    }

    public void setId(String id) {
        Id = id;
    }

    public String getImg() {
        return Img;
    }

    public void setImg(String img) {
        Img = img;
    }

    public String getName() {
        return Name;
    }

    public void setName(String name) {
        Name = name;
    }

    public int getImageId() {
        return imageId;
    }

    public void setImageId(int imageId) {
        this.imageId = imageId;
    }

    public String getSelectTag() {
        return selectTag;
    }

    public void setSelectTag(String selectTag) {
        this.selectTag = selectTag;
    }

    public int getSelectNum() {
        return selectNum;
    }

    public void setSelectNum(int selectNum) {
        this.selectNum = selectNum;
    }
}

Adapter代码:

public class VideoListAdapter extends RecyclerView.Adapter {

    private LayoutInflater mInflater;
    private Context mContext;
    private ArrayList mDatas;

    private String mAdapterType;
    private int productnum = 1;

    List mSubmitOrderList = null;


    public interface OnItemClickListener {
        void onItemClick(View view, int position, ArrayList msg);

        void onItemLongClick(View view, int position);
    }

    private OnItemClickListener mOnItemClickListener;

    public void setmOnItemClickListener(OnItemClickListener listener) {
        this.mOnItemClickListener = listener;
    }

    public VideoListAdapter(Context context, ArrayList datas, String adapterType) {
        this.mContext = context;
        this.mDatas = datas;
        this.itmeViewTag = adapterType;
        mInflater = LayoutInflater.from(context);
    }

    }

    public void removeorder() {

        for (int i = 0; i < mDatas.size(); i++) {

                    return true;
                }
            });
        }
    }

    @Override
    public int getItemCount() {

        /**
