【问题描述】：

所以我有一个listView，每个项目基本上显示3个TextView-s，其中一个TextView-s代表用户名，如果用户名等于登录用户，则项目应突出显示（见代码）

import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import java.util.List;

public class ListAdapter extends ArrayAdapter<HallOfFame.User> 

private int resourceLayout;
private Context mContext;

public ListAdapter(Context context, int resource, List<HallOfFame.User> items) 
    super(context, resource, items);
    this.resourceLayout = resource;
    this.mContext = context;


@Override
public View getView(int position, View convertView, ViewGroup parent) 
    View v = convertView;

    if (v == null) 
        LayoutInflater vi;
        vi = LayoutInflater.from(mContext);
        v = vi.inflate(resourceLayout, null);
    

    HallOfFame.User user = getItem(position);

    if (user != null) 
        TextView rankText = v.findViewById(R.id.rank);
        TextView usernameText = v.findViewById(R.id.username);
        TextView scoreText = v.findViewById(R.id.score);

        rankText.setText(Integer.toString(user.rank));
        usernameText.setText(user.username);
        scoreText.setText(Integer.toString(user.overall));

        if(Utils.USERNAME.equals(user.username))
            usernameText.setTextColor(Color.RED);
        
    

    return v;

在这个例子中，只有 MikiThenics 应该被突出显示。在 if(Utils.USERNAME.eq...) 之后添加 else 将阻止其他用户名被突出显示，但右侧的数字仍然存在这种奇怪的变化。并且“不工作”的项目并不总是相同的。

这是 HallOfFame.User 的外观：

public class User
    public String username;
    public int pullups=0,pushups,dips,handstandpushups,plank,pistolsquats,muscleups;
    public int overall;
    public int rank = 0;
    public User(String data,int i)
        try 
            JSONObject jsonObject = new JSONObject(data);
            username = jsonObject.getString(Utils.S_USERNAME);
            pullups = jsonObject.getInt(Utils.S_PULL_UPS);
            pushups = jsonObject.getInt(Utils.S_PUSH_UPS);
            dips = jsonObject.getInt(Utils.S_DIPS);
            handstandpushups = jsonObject.getInt(Utils.S_HANDSTAND_PUSHUPS);
            plank = jsonObject.getInt(Utils.S_PLANK);
            pistolsquats = jsonObject.getInt(Utils.S_PISTOL_SQUATS);
            muscleups = jsonObject.getInt(Utils.S_MUSCLE_UPS);
            overall = pullups+pushups+dips+handstandpushups+pistolsquats+muscleups+plank/60;

            rank = i;
            if(username.equals(Utils.USERNAME))
                yourPosition = i;
        catch (Exception e)

        
    

这是我正在使用的 JSON 示例

        String tmp =  "[\"username\":\"MikiThenics\",\"pullups\":\"25\",\"pushups\":\"70\",\"dips\":\"30\",\"handstandpushups\":\"16\",\"muscleups\":\"8\",\"pistolsquats\":\"1\",\"plank\":\"360\",\"username\":\"user01\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user02\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user0\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user1\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user2\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user3\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user4\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user5\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user6\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user7\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user8\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user9\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user10\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user11\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user12\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user13\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user14\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user15\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user16\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user17\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user18\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user19\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user20\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user21\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user22\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user23\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user24\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user25\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user26\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"username\":\"user27\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\",\"user

问题是由用户名引起的。由于将用户中的用户名设置为固定字符串可以解决问题。 即使我使用固定字符串作为 JSON，重新启动活动时“不工作的项目”也不相同。

【问题讨论】：

添加 else 块。 else usernameText.setTextColor(Color.BLACK);

是的，我提到添加 else 会有所帮助，但右侧的奇怪变化仍然存在

scoreText.setText(String.valuesof(user.overall));

@IntelliJAmiya 仍然没有问题是由用户名引起的，因为使用固定字符串作为用户名“修复”了问题，奇怪的是即使使用固定的 json 字符串也会在重新启动活动后导致不同的损坏项目

解决了吗？

【参考方案1】：

这是一个 XML 问题。你可以试试这个。

【讨论】：

我不知道为什么它们中的一些仍然是红色的，但是这种转变已经消失了，其他人会这样做。谢谢;)

【参考方案2】：

您可以在 if 语句中添加一个布尔值，起初它是 true，当尝试突出显示用户名的文本时，将布尔值设置为 false

if(Utils.USERNAME.equals(user.username) && boolean)
            usernameText.setTextColor(Color.RED);
        

【讨论】：

是的，或者我可以简单地使用 else，但左边数字的奇怪变化仍然存在
