回收站视图中不工作

问题描述：

查看加载，我实现了这个之后： -

holder.time.setText(user.getTime());

到

holder.time.setText(Integer.toString(user.getTime()));

，但我仍然可以在登录此消息： -

E/RecyclerView: No adapter attached; skipping layout

对此有何想法？

我已经使用抽射从服务器获取数据，然后

显示了使用Cardview上回收站视图中的数据。但它崩溃的应用程序错误，说适配器没有连接。虽然我已经连接了适配器。我无法找到问题。请帮忙。

主要布局文件

<?xml version="1.0" encoding="utf-8"?>

主要的Java类

public class Leaderboard extends AppCompatActivity { 

private static final String URL = "URL"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_leaderboard); 

    final RecyclerView recycler = (RecyclerView) findViewById(R.id.recycle); 
    recycler.setLayoutManager(new LinearLayoutManager(Leaderboard.this)); 

    StringRequest request = new StringRequest(URL, new Response.Listener<String>() {

    RequestQueue queue = Volley.newRequestQueue(this); 
    queue.add(request); 
}

Cardview

RecyclerviewAdapter

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

private Context context; 
private User[] data; 
public RecyclerviewAdapter(Context context, User[] data){ 
    this.context = context; 
    this.data = data; 
} 

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

@Override 
public void onBindViewHolder(RecyclerViewHolder holder, int position) { 
    User user = data[position]; 
    holder.name.setText(user.getName()); 
    holder.time.setText(user.getTime()); 
    // holder.rank.setText(""+data[position+1]); 
} 

@Override 
public int getItemCount() { 
    return data.length; 
} 

public class RecyclerViewHolder extends RecyclerView.ViewHolder{ 
    TextView rank,name,time; 
    public RecyclerViewHolder(View itemView) { 
     super(itemView); 
     rank = (TextView) itemView.findViewById(R.id.rank); 
     name = (TextView) itemView.findViewById(R.id.name); 
     time = (TextView) itemView.findViewById(R.id.time); 
    } 
} 
}

我莫代尔类

public class User { 

@SerializedName("name") 
@Expose 
private String name; 
@SerializedName("time") 
@Expose 
private Integer time; 
@SerializedName("id") 
@Expose 
private String id; 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public Integer getTime() { 
    return time; 
} 

public void setTime(Integer time) { 
    this.time = time; 
} 

public String getId() { 
    return id; 
} 

public void setId(String id) { 
    this.id = id; 
} 
}

我无法在这里找到问题。请帮助

的问题与缺失资源，分不清到底是哪，但它是在缺少行：RecyclerviewAdapter.java:34 - 你想设置一个文本值，但资源你正在设置不存在。 – Booger

答

尝试改变代码

holder.time.setText(user.getTime());

到

holder.time.setText(Integer.toString(user.getTime()));

现在加载视图，但错误日志仍然显示下面的错误。对此有何想法？ E/RecyclerView：没有连接适配器;跳过布局 –

@RaviBhardwaj - 那是因为你的代码recycler.setAdapter（new RecyclerviewAdapter（Leaderboard.this，users））;没有在应用程序主线程上设置。你可以做的是移动你的代码setAdapter onCreate和onResponse调用notifyDataStateChanged recyclerview –

答

的问题是在此代码

holder.time.setText(user.getTime());

由于TextView的重载的setText（INT）

应该与字符串资源一起使用的方法，这些资源将通过像R.string。*定义的整数来解决。

在你的情况下用户。getTime（）返回的整型值将被视为预定义的XML字符串资源（在您的情况下不存在）。

答

E/RecyclerView: No adapter attached; skipping layout

这意味着没有适配器，因此布局将被跳过，那不是错误是信息。如果您不想再看到它，请连接一个空适配器，然后更新适配器。

这是你的错误：

E/AndroidRuntime: FATAL EXCEPTION: main 
            Process: com.ravibhardwaj.kbcmaster, PID: 6718 
                     android.content.res.Resources$NotFoundException: String resource ID #0xf0

正因为如此：

holder.time.setText(user.getTime());

因为：

public Integer getTime() { 
    return time; 
}

这是一个整数，setText()可以接受字符串或整型，因为资源如R.string.something是int。修复：

holder.time.setText(String.valueOf(user.getTime()));

回收站视图中不工作
