Question

当我点击RecyclerView的任何项目时。它会告诉我这个项目的细节。我怎样才能做到这一点？我使用过Retrofit库。我为这个RecyclerView创建了一个适配器。我已经提到了它。

的活动：

List<TargetFile> targetfiles=response.body().getTargetfileslist();

Log.d(TAG,"Number of targetfileslist: "+targetfiles.size());
recyclerView.setAdapter(new TargetFileAdapter(targetfiles,R.layout.list_item_targetfile,getApplicationContext()));  //RecyclerView

适配器：

public class TargetFileAdapter extends RecyclerView.Adapter<TargetFileAdapter.TargetFileViewHolder> {

    private List<TargetFile> targetfiles;
    private int rowLayout;
    private Context context;

    public TargetFileAdapter(List<TargetFile> targetfiles, int rowLayout, Context context) {
        this.targetfiles = targetfiles;
        this.rowLayout = rowLayout;
        this.context = context;
    }



    public static class TargetFileViewHolder extends RecyclerView.ViewHolder{
        LinearLayout targetFilesLayout;
        TextView fileno,partyname,mobile,address;

        public TargetFileViewHolder(View v){
            super(v);
            targetFilesLayout=(LinearLayout)v.findViewById(R.id.targetfile_layout);
            fileno=(TextView)v.findViewById(R.id.fileno);
            partyname=(TextView)v.findViewById(R.id.partyname);
            address=(TextView)v.findViewById(R.id.adrs);
        }
    }

    @Override
    public TargetFileAdapter.TargetFileViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
        View view= LayoutInflater.from(parent.getContext()).inflate(rowLayout,parent,false);
        return new TargetFileViewHolder(view);
    }

    @Override
    public void onBindViewHolder(TargetFileViewHolder holder,final int position){
        holder.fileno.setText(targetfiles.get(position).getFileno());
        holder.partyname.setText(targetfiles.get(position).getPartyname());
        holder.address.setText(targetfiles.get(position).getAddress());

    }

    @Override
    public int getItemCount() {
        return targetfiles.size();
    }
}

iimport android.support.v7.widget.RecyclerView; import android.view.View;

public class TargetFileAdapter extends RecyclerView.Adapter<TargetFileAdapter.TargetFileViewHolder> {

    private List<TargetFile> targetfiles;
    private int rowLayout;
    private Context context;
    private OnTargetFileListener listener;

    public TargetFileAdapter(List<TargetFile> targetfiles, int rowLayout, Context context, OnTargetFileListener listener) {
        this.targetfiles = targetfiles;
        this.rowLayout = rowLayout;
        this.context = context;
        this.listener = listener;
    }

    @Override
    public TargetFileAdapter.TargetFileViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(rowLayout, parent, false);
        return new TargetFileViewHolder(view);
    }

    @Override
    public void onBindViewHolder(TargetFileViewHolder holder, final int position) {
        holder.fileno.setText(targetfiles.get(position).getFileno());
        holder.partyname.setText(targetfiles.get(position).getPartyname());
        holder.address.setText(targetfiles.get(position).getAddress());

    }

    @Override
    public int getItemCount() {
        return targetfiles.size();
    }

    public static class TargetFileViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        LinearLayout targetFilesLayout;
        TextView fileno, partyname, mobile, address;

        public TargetFileViewHolder(View v) {
            super(v);
            targetFilesLayout = (LinearLayout) v.findViewById(R.id.targetfile_layout);
            fileno = (TextView) v.findViewById(R.id.fileno);
            partyname = (TextView) v.findViewById(R.id.partyname);
            address = (TextView) v.findViewById(R.id.adrs);

            v.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            if (listener == null){
                return;
            }

            TargetFile file = targetfiles.get(getAdapterPosition());
            listener.onFileTargetClicked(file);
        }
    }

    public interface OnTargetFileListener {
        void onTargetFileClicked(TargetFile file);
    }
}

此代码应该适合您。您需要在活动中或使用适配器的位置实现OnTargetFileListener。

祝你好运！

我怎么能写＆＃34; onItemClickListener＆＃34;在RecyclerView中？
