Question

我自己构建了一个带有recyclerview和汉堡菜单的自定义导航抽屉。我创建了用于处理项目点击的界面以及ItemTouchHelper类，但抽屉项目没有响应点击事件，只是快速关闭抽屉。

我也尝试在适配器中设置click事件但仍然是相同的情况。这是我的代码：

适配器：

public class RecyclerDrawerAdapter extends RecyclerView.Adapter<RecyclerDrawerHolder> {

private final Context context;
private List<DrawerItems> itemsList;

private String decodedImage;
private SharedPreferences imagePrefs;

private final ConnectionDetector detector;

public RecyclerDrawerAdapter(Context context, List<DrawerItems> itemsList) {
    this.context = context;
    this.itemsList = itemsList;
    detector = new ConnectionDetector(context);
}

@Override
public RecyclerDrawerHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_menu_items_layout, parent, false);
    return new RecyclerDrawerHolder(view);
}

@Override
public void onBindViewHolder(RecyclerDrawerHolder viewholder, final int position) {
    DrawerItems drawerItems = itemsList.get(position);
    viewholder.menuTitleTV.setText(drawerItems.getTitleTxt());

    if (!detector.isConnected()){
        getImageFromPrefs();
    } else {
        fetchUserImageOnline();
    }

    Picasso.with(context)
            .load(drawerItems.getIconImg())
            .into(viewholder.menuIcon);

    //viewholder.badgeCountTV.setText(drawerItems.getBadgeCount());
    viewholder.badgeCountTV.setVisibility(View.GONE);

    viewholder.setClickListener(new RecyclerClickListener() {
        @Override
        public void onClick(View view, int position) {
            switch (position){
                case 0:
                    context.startActivity(new Intent(context, MyProfileActivity.class));
                    break;
                case 1:
                    context.startActivity(new Intent(context, ChatsActivity.class));
                    break;
                case 2:
                    context.startActivity(new Intent(context, MyHugsActivity.class));
                    break;
                case 3:
                    context.startActivity(new Intent(context, ChatCirclesActivity.class));
                    break;
                case 4:
                    context.startActivity(new Intent(context, SettingsActivity.class));
                    break;
            }
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    });

}

@Override
public int getItemCount() {
    if (itemsList == null) {
        return 0;
    }
    return itemsList.size();
}

private void fetchUserImageOnline() {

}

private void getImageFromPrefs() {
    imagePrefs = context.getSharedPreferences("ImagePrefs", Context.MODE_PRIVATE);
    decodedImage = imagePrefs.getString("image_user", null);

    RecyclerDrawerHolder holder = null;
    if (!decodedImage.equalsIgnoreCase("") || !decodedImage.isEmpty()){
        byte[] bytes = Base64.decode(decodedImage, Base64.DEFAULT);
        Bitmap userBitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
        if (userBitmap != null){


            holder.menuIcon.setImageBitmap(userBitmap);
        } else {
            holder.menuIcon.setImageDrawable(context.getResources().getDrawable(R.drawable.person_avatar));
        }
    }

}

}

我的活动代码，用于设置recyclerview和处理点击事件：

private void setUpDrawer() {
    recyclerDrawer.setHasFixedSize(true);
    recyclerDrawer.setLayoutManager(new LinearLayoutManager(this));

    //DrawerItems drawerItems = new DrawerItems(R.drawable.send_round, "Profile", 99);
    DrawerItems drawerItems = new DrawerItems(R.drawable.send_round, "Profile", 99);
    itemsList.add(drawerItems);

    DrawerItems drawerItems2 = new DrawerItems(R.drawable.chats, "Chats", 80);
    itemsList.add(drawerItems2);

    DrawerItems drawerItems3 = new DrawerItems(R.drawable.hugs, "Hugs",90);
    itemsList.add(drawerItems3);

    DrawerItems drawerItems4 = new DrawerItems(R.drawable.chat_circles, "Chat Circles", 67);
    itemsList.add(drawerItems4);

    DrawerItems drawerItems5 = new DrawerItems(R.drawable.settings, "Settings", 0);
    itemsList.add(drawerItems5);

    drawerAdapter = new RecyclerDrawerAdapter(this, itemsList);
    recyclerDrawer.setAdapter(drawerAdapter);

    toolbar.setNavigationIcon(R.drawable.burger_menu);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (drawerLayout.isDrawerOpen(GravityCompat.START)){
                drawerLayout.closeDrawer(GravityCompat.START);
            } else {
                //setClickListener();
                drawerLayout.openDrawer(GravityCompat.START);
            }
        }
    });

    setDrawerClickListener();

}

private void setDrawerClickListener() {
    recyclerDrawer.addOnItemTouchListener(new RecyclerItemTouchListener(this, recyclerDrawer, new RecyclerClickListener() {
        @Override
        public void onClick(View view, int position) {
            switch (position){
                case 0:
                    Toast.makeText(HomeActivity.this, "Profile Activity", Toast.LENGTH_LONG).show();
                    break;
                case 1:
                    Toast.makeText(HomeActivity.this, "PersonalChat Activity", Toast.LENGTH_LONG).show();
                    //drawerLayout.closeDrawer(GravityCompat.START);
                    break;
                case 2:
                    Toast.makeText(HomeActivity.this, "My Hugs Activity", Toast.LENGTH_LONG).show();
                    //drawerLayout.closeDrawer(GravityCompat.START);
                    break;
                case 3:
                    Toast.makeText(HomeActivity.this, "ChatCircles Activity", Toast.LENGTH_LONG).show();
                    //drawerLayout.closeDrawer(GravityCompat.START);
                    break;
                case 4:
                    Toast.makeText(HomeActivity.this, "Settings Activity", Toast.LENGTH_LONG).show();
                    //drawerLayout.closeDrawer(GravityCompat.START);
                    break;
            }
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));
}

private void initWidgets() {
    toolbar = findViewById(R.id.toolbar);
    drawerLayout = findViewById(R.id.drawerLayout);

    displayMsgsRV = findViewById(R.id.home_messagesRV);
    recyclerDrawer = findViewById(R.id.recyclerDrawer);
    home_inputMsgTET = findViewById(R.id.home_inputMsgTET);
    send_msg_iv = findViewById(R.id.send_msg_iv);

    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle("");

    setUpDrawer();

    send_msg_iv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            sendMessage();
        }
    });

    //getPublicMessages();

}

这是我建议的布局文件：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawerLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">   

   <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_gravity="start"
       android:orientation="vertical">

       <android.support.v7.widget.RecyclerView
           android:id="@+id/recyclerDrawer"
           android:layout_width="150dp"
           android:layout_height="match_parent"
           android:background="@android:color/black" />

   </LinearLayout>

   <FrameLayout
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_below="@+id/toolbar"
       android:id="@+id/containerFrag"/>

 </android.support.v4.widget.DrawerLayout>

DrawerItems是我的模型类。请大家帮忙，我似乎不知道为什么会这样。感谢。
