需要通过行检测检测我的RecyclerView上的点击和触摸事件

Question

我尝试使用教程为我的RecyclerView设置click和toch监听器。但是我尝试过的每一个教程最终都失败了，因为我已经用其他教程设置了RecyclerView，并且所有教程看起来都不同。请问你能帮助我检测每一行的点击吗？例如，当用户单击我的第一行（这是一个注销字段）时，它应该从应用程序中注销用户。我的所有注销操作都有效，但点击RecyclerView不会。

我的设置适配器：

import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;

import java.util.List;

public class SettingsAdapter extends RecyclerView.Adapter<SettingsAdapter.MySettingHolder> {

    private List<Settings> settingList;

    public class MySettingHolder extends RecyclerView.ViewHolder {
        public ImageView settingImage;
        public TextView settingTitle, settingSubtitle;

        public MySettingHolder(View view) {
            super(view);
            settingImage = (ImageView) view.findViewById(R.id.settingImage);
            settingTitle = (TextView) view.findViewById(R.id.settingTitle);
            settingSubtitle = (TextView) view.findViewById(R.id.settingSubtitle);
        }
    }

    public SettingsAdapter (List<Settings> settingList) {
        this.settingList = settingList;
    }

    @Override
    public MySettingHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.settings_list_row, parent, false);

        return new MySettingHolder(itemView);
    }

    @Override
    public void onBindViewHolder(MySettingHolder holder, int position) {
        // Setting for one entry
        Settings setting = settingList.get(position);

        holder.settingImage.setImageResource(setting.getSettingImageUrl());
        // If the settingSubtitle is empty it should be not visible and just the settingTitle
        if (setting.getSettingSubtitle().equals("")) {
            holder.settingTitle.setText(setting.getSettingTitle());
            holder.settingSubtitle.setVisibility(View.GONE);
        } else {
            holder.settingTitle.setText(setting.getSettingTitle());
            holder.settingSubtitle.setText(setting.getSettingSubtitle());
        }
    }

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

}

这是我实现RecyclerView

的SettingsFragment

Answer 1

    @Override
    public void onBindViewHolder(MySettingHolder holder, int position) {
        // Setting for one entry
        Settings setting = settingList.get(position);

        holder.settingImage.setImageResource(setting.getSettingImageUrl());
        // If the settingSubtitle is empty it should be not visible and just the settingTitle
        if (setting.getSettingSubtitle().equals("")) {
            holder.settingTitle.setText(setting.getSettingTitle());
            holder.settingSubtitle.setVisibility(View.GONE);
        } else {
            holder.settingTitle.setText(setting.getSettingTitle());
            holder.settingSubtitle.setText(setting.getSettingSubtitle());
        }

        holder.type = setting.getType();
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                MySettingHolder holder = (MySettingHolder )(v.getTag());
                switch (holder.type) {

                    case 1:                        
                        // do logout
                        break;

                    case 2:                        
                        // do other stuff
                        break;

                    default:
                        break;
                }
            }
        });

        // set viewholder
        holder.itemView.setTag(holder);
    }

同时提醒您更新ViewHolder这样的内容并将类型变量添加到Settings.class

public class MySettingHolder extends RecyclerView.ViewHolder {

        public int type;
        public ImageView settingImage;
        public TextView settingTitle, settingSubtitle;

        public MySettingHolder(View view) {
            super(view);
            settingImage = (ImageView) view.findViewById(R.id.settingImage);
            settingTitle = (TextView) view.findViewById(R.id.settingTitle);
            settingSubtitle = (TextView) view.findViewById(R.id.settingSubtitle);
        }
    }
