Question

Recyclerview项目点击并不总是有效，有时可以工作，但有更多点击（不知道点击了多少）。如果只点击一次无法点击。

注意前几天我尝试点击一次就可以了，但是现在当我尝试使用AS再次运行时它不起作用，即使我没有修改该文件

我的代码

public class RecyclerViewAdapterRiwayat extends RecyclerView.Adapter<RecyclerViewAdapterRiwayat.ViewHolder> {

    Context context;
    private static final String TAG = RecyclerViewAdapterRiwayat.class.getSimpleName();

    List<GetDataAdapterRiwayat> getDataAdapter;

    ImageLoader imageLoader1;
    String FIXURL = "http://192.168.1.101/AndroidFileUpload/";
    String url = FIXURL + "uploads/";
    String StatusRiwayat;


    public RecyclerViewAdapterRiwayat(List<GetDataAdapterRiwayat> getDataAdapter, Context context) {

        super();
        this.getDataAdapter = getDataAdapter;
        this.context = context;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items_riwayat, parent, false);

        ViewHolder viewHolder = new ViewHolder(v);

        return viewHolder;
    }

    @Override
    public void onBindViewHolder(ViewHolder Viewholder, int position) {

        final GetDataAdapterRiwayat getDataAdapter1 = getDataAdapter.get(position);

        imageLoader1 = ServerImageParseAdapter.getInstance(context).getImageLoader();

        imageLoader1.get(url+getDataAdapter1.getFotoSetelahRiwayat(),
                ImageLoader.getImageListener(
                        Viewholder.networkImageView,//Server Image
                        R.mipmap.ic_launcher,//Before loading server image the default showing image.
                        android.R.drawable.ic_dialog_alert //Error image if requested image dose not found on server.
                )
        );
        Viewholder.networkImageView.setImageUrl(url+getDataAdapter1.getFotoSetelahRiwayat(), imageLoader1);


        Viewholder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "coba nih5 : "+getDataAdapter1.getNamaJalanRiwayat());

                Intent intent = new Intent(v.getContext(), DetailRiwayatActivity.class);
                context.startActivity(intent);
            }
        });

    }

    @Override
    public int getItemCount() {

        return getDataAdapter.size();
    }

    class ViewHolder extends RecyclerView.ViewHolder{

        public TextView ImageTitleNameView;
        public NetworkImageView networkImageView;

        public ViewHolder(View itemView) {

            super(itemView);
            ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item_riwayat);

            networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView2);
        }


    }
}

如果您在滚动/推送RecyclerView后只遇到问题，那么它是SupportLibrary中的一个已知错误

用户滚动后，他们无法点击RecyclerView中的项目。（AOSP问题66996774）

Issuetracker ID 66996774以及69823266因为它仍未在27.0.1中修复。即使Google声明it has fixed it。

最重要的是：这里的解决方案（来自Chris Banes，Googler）非常有效：https://gist.github.com/chrisbanes/8391b5adb9ee42180893300850ed02f2

试试这个：

   class ViewHolder extends RecyclerView.ViewHolder{

            public TextView ImageTitleNameView;
            public NetworkImageView networkImageView;

            public ViewHolder(View itemView) {

                super(itemView);
                ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item_riwayat);

                networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView2);


                itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                int position = getLayoutPosition(); // use this to get item from list
                    Log.d(TAG, "coba nih5 : "+getDataAdapter1.getNamaJalanRiwayat());

                    Intent intent = new Intent(v.getContext(), DetailRiwayatActivity.class);
                    context.startActivity(intent);
                }
            });
        }

您的代码

Viewholder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "coba nih5 : "+getDataAdapter1.getNamaJalanRiwayat());

                Intent intent = new Intent(v.getContext(), DetailRiwayatActivity.class);
                context.startActivity(intent);
            }
        });

每次在itemView上创建新的侦听器，而是在分配新的侦听器之前实现OnClickListener或传递 null

 Viewholder.itemView.setOnClickListener(null);
Viewholder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "coba nih5 : "+getDataAdapter1.getNamaJalanRiwayat());

                Intent intent = new Intent(v.getContext(), DetailRiwayatActivity.class);
                context.startActivity(intent);
            }
        });

或在ViewHolder onCreateViewHolder()

中添加听众

v.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                int position = viewHolder.getAdapterPosition(); // use this to get item from list
                    Log.d(TAG, "coba nih5 : "+getDataAdapter1.getNamaJalanRiwayat());

                    Intent intent = new Intent(v.getContext(), DetailRiwayatActivity.class);
                    context.startActivity(intent);
                }
            });

Answer 4

将这些添加到R.layout.recyclerview_items_riwayat

的父元素中

android:clickable="false"
android:focusable="false"

Answer 5

这可能是由于父级的onTouch方法拦截了触摸事件。您需要检查是否有像SwipeLayout这样的父视图。
