我有一个排行榜，根据你的排名给你的名字上色。每花10欧元，就有一种新的颜色。最后一个等级是渐变色。它按照应有的方式为所有内容着色，除了第14项（位置13）。它给一个渐变颜色，而不管排名，名称，项目数量或其他任何东西。以下是MyAdapter：

package com.miskolin.app;

import android.content.Context;

import java.util.List;

public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

    Context context;
    List<Item> items;

    public MyAdapter(Context context, List<Item> items) {
        this.context = context;
        this.items = items;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return new MyViewHolder(LayoutInflater.from(context).inflate(R.layout.item_view,parent,false));
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        holder.user.setText(items.get(position).getUser());
        holder.total.setText(items.get(position).getTotalSpent());
        Integer rank = items.get(position).getLeadersRank();
        int[][] rankColors = {
                {
                        context.getResources().getColor(R.color.Rank0),  // Rank 0
                        context.getResources().getColor(R.color.Rank1),  // Rank 1
                        context.getResources().getColor(R.color.Rank2),  // Rank 2
                        context.getResources().getColor(R.color.Rank3),  // Rank 3
                        context.getResources().getColor(R.color.Rank4),  // Rank 4
                        context.getResources().getColor(R.color.Rank5),  // Rank 5
                        context.getResources().getColor(R.color.Rank6),  // Rank 6
                        context.getResources().getColor(R.color.Rank7) , // Rank 7
                        context.getResources().getColor(R.color.Rank8)   // Rank 8
                },
                {
                        context.getResources().getColor(R.color.Rank9c1),
                        context.getResources().getColor(R.color.Rank9c2),
                        context.getResources().getColor(R.color.Rank9c3)
                }
        };

        if (rank >= rankColors[0].length) {
            Log.d("Debug", "Using LinearGradient for item at position " + position);
            TextPaint paint = holder.user.getPaint();
            Shader shader = new LinearGradient(0, 100, 3, 20, rankColors[1], null, Shader.TileMode.CLAMP);
            paint.setShader(shader);
            holder.user.setTextColor(rankColors[0][0]);
        } else {
            for (int i = 0; i < rankColors[0].length; i++) {
                if (rank.equals(i)) {
                    Log.d("Debug", "Using Color for item at position " + position);
                    holder.user.setTextColor(rankColors[0][i]);
                    Log.d("color", holder.user.getText() + " " + Integer.toHexString(rankColors[0][i]));
                    break;
                }
            }

        }
    }

    @Override
    public int getItemCount() {

        return items.size();
    }
}

以下是MyViewHolder：

package com.miskolin.app;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import android.view.View;
import android.widget.TextView;

import org.w3c.dom.Text;

public class MyViewHolder extends RecyclerView.ViewHolder {

    TextView user,total;

    public MyViewHolder(@NonNull View itemView) {
        super(itemView);
        user = itemView.findViewById(R.id.userView);
        total = itemView.findViewById(R.id.total);
    }
}

所以我摆弄了一下recyclerview margin_bottom，发现颜色不正确的项目的位置在某种程度上与recyclerview的高度有关

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

    android:layout_width="match_parent"
    android:background="@drawable/miskolin_leaderboard_background"
    android:layout_height="match_parent"
    tools:context=".Graphs">


    <ImageButton
        android:id="@+id/main"

        android:scaleType="fitCenter"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="10dp"
        android:layout_centerHorizontal="true"/>

    <TextView

        android:text="Lestvica"
        android:textStyle="bold"
        android:textSize="40dp"
        android:textColor="#B6B3A7"
        android:gravity="center"
        android:layout_marginTop="50dp"/>

    <ImageView
        android:id="@+id/crown"
        android:layout_width="70dp"
        android:layout_height="70dp"

        android:layout_centerHorizontal="true"
        android:layout_marginTop="80dp"
        app:srcCompat="@drawable/crown" />
    <androidx.recyclerview.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/main"
        android:layout_below="@id/crown"
        android:id="@+id/recyclerview"/>

</RelativeLayout>

此设置现在不正确地为第15个项目着色
