自定义 RecyclerClickListener 对于多个 onClick 无法正常工作

Question

我有一个包含自定义 onClickListener 的 Recyclerview。现在我可以在点击整个 recyclerview 项目时进入下一页。我将如何单独单击图像、文本和复选框。

我当前的代码如下：

        RecyclerView rv = (RecyclerView) v.findViewById(R.id.home_recyclerview);
        LinearLayoutManager llm = new LinearLayoutManager(getContext());
        rv.setLayoutManager(llm);
        rv.setItemAnimator(new DefaultItemAnimator());
        rv.setHasFixedSize(true); // to improve performance
        rv.setAdapter(new HomeManager()); // the projectdatabase manager is assigner to the RV

        rv.addOnItemTouchListener( // and the click is handled
                new RecyclerClickListener(getContext(), new RecyclerClickListener.OnItemClickListener() {
                    @Override
                    public void onItemClick(View view, int position) {
                        Intent intent = new Intent(getActivity(), HomeRecyclerDetailActivity.class);
                        intent.putExtra(HomeRecyclerDetailActivity.ID, HomeData.PROJECTS[position].getId());
                        ActivityTransitionLauncher.with(getActivity()).from(view).launch(intent);
                    }
                }));
        return v;
    }
}

import android.support.design.widget.Snackbar;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.example.root5solutions.mirrealtors.R;


public class HomeManager extends RecyclerView.Adapter<HomeManager.RecyclerViewHolder> {

    public static class RecyclerViewHolder extends RecyclerView.ViewHolder {

        TextView mProjectName, mProjectCity, mProjectType;
        ImageView mImage;
        CheckBox mCheck;
        RelativeLayout mProjectStatus;

        RecyclerViewHolder(View itemView) {
            super(itemView);
            mProjectName = (TextView) itemView.findViewById(R.id.PROJECT_name);
            mProjectCity = (TextView) itemView.findViewById(R.id.PROJECT_city);
            mProjectType = (TextView) itemView.findViewById(R.id.PROJECT_type);
            mImage = (ImageView) itemView.findViewById(R.id.PROJECT_image);
            mCheck = (CheckBox) itemView.findViewById(R.id.PROJECT_fav);
            mProjectStatus = (RelativeLayout) itemView.findViewById(R.id.label);
        }
    }

    @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recyclerview_item, viewGroup, false);
        return new RecyclerViewHolder(v);
    }

    @Override
    public void onBindViewHolder(final RecyclerViewHolder viewHolder, int i) {
        // get the single element from the main array

        final HomeData projects = HomeData.PROJECTS[i];
        // Set the values
        viewHolder.mProjectName.setText(projects.get(HomeData.Field.NAME));
        viewHolder.mProjectCity.setText(projects.get(HomeData.Field.CITY));
        viewHolder.mProjectType.setText(projects.get(HomeData.Field.TYPE));
        viewHolder.mImage.setImageResource(projects.geti(HomeData.Field.IMAGE));

  }


    @Override
    public int getItemCount() {

        return HomeData.PROJECTS.length;
    }


}

自定义 RecyclerClickListener

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;


public class RecyclerClickListener implements RecyclerView.OnItemTouchListener {

    private OnItemClickListener mOnClickListener;
    GestureDetector mGestureDetector;

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

    public RecyclerClickListener(Context context, OnItemClickListener listener) {
        mOnClickListener = listener;
        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());
        if (childView != null && mOnClickListener != null && mGestureDetector.onTouchEvent(e)) {
            mOnClickListener.onItemClick(childView, view.getChildPosition(childView));
            return true;
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }

}

您应该创建自己的侦听器并将其传递给HomeManager。然后在 onBindViewHolder 中为您想要的每个元素设置 onClickListeners 并在 onClick 中调用侦听器中的正确方法。
