Question

我正在开发一种基于纸牌的游戏，在该游戏中，我必须在每个回合之后显示每个玩家的得分。为此，我创建了一个记分板类，并使用Listview显示了球员的姓名和得分。

以下是我的代码

ScoreCardPopup类

公共类ScoreCardPopup {

private List<Items> itemsList = new ArrayList<Items>();
private ListView listView;
private CustomListAdapter adapter;
private ArrayList<String> playernames = new ArrayList<>();
private ArrayList<Integer> playerscore = new ArrayList<>();
Context context;

public ScoreCardPopup(ArrayList<String> playernames, ArrayList<Integer> playerscore) {
    this.playernames = playernames;
    this.playerscore = playerscore;
}

public ScoreCardPopup(ArrayList<String> playernames, ArrayList<Integer> playerscore, Context context) {
    this.playernames = playernames;
    this.playerscore = playerscore;
    this.context = context;
}

public void showScoreCard() {
    final Dialog dialog = new Dialog(context);
    dialog.setContentView(R.layout.activity_score_card);
    //Initialize and create a new adapter with layout named list found in activity_main layout
    listView = (ListView) dialog.findViewById(R.id.list);
    adapter = new CustomListAdapter(context, itemsList);
    listView.setAdapter(adapter);
    int i = 0;
    while (i < playernames.size()) //Add to the Items array
    {
        Items items = new Items();
        items.setName(playernames.get(i).toString());
        items.setScore(playerscore.get(i).toString());
        itemsList.add(items);
        i++;
    }
    //All done, so notify the adapter to populate the list using the Items Array
    adapter.notifyDataSetChanged();
    dialog.show();

}
}

CustomListAdapter类

public class CustomListAdapter extends BaseAdapter {

private Context context;
private LayoutInflater inflater;
private List<Items> items;

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

/**
 * How many items are in the data set represented by this Adapter.
 *
 * @return Count of items.
 */
@Override
public int getCount() {
    return items.size();
}

/**
 * Get the data item associated with the specified position in the data set.
 *
 * @param position Position of the item whose data we want within the adapter's
 *                 data set.
 * @return The data at the specified position.
 */
@Override
public Object getItem(int position) {
    return items.get(position);
}

/**
 * Get the row id associated with the specified position in the list.
 *
 * @param position The position of the item within the adapter's data set whose row id we want.
 * @return The id of the item at the specified position.
 */
@Override
public long getItemId(int position) {
    return position;
}

/**
 * Get a View that displays the data at the specified position in the data set. You can either
 * create a View manually or inflate it from an XML layout file. When the View is inflated, the
 * parent View (GridView, ListView...) will apply default layout parameters unless you use
 * {@link LayoutInflater#inflate(int, ViewGroup, boolean)}
 * to specify a root view and to prevent attachment to the root.
 *
 * @param position  The position of the item within the adapter's data set of the item whose view
 *                  we want.
 * @param scoreView The old view to reuse, if possible. Note: You should check that this view
 *                  is non-null and of an appropriate type before using. If it is not possible to convert
 *                  this view to display the correct data, this method can create a new view.
 *                  Heterogeneous lists can specify their number of view types, so that this View is
 *                  always of the right type (see {@link #getViewTypeCount()} and
 *                  {@link #getItemViewType(int)}).
 * @param parent    The parent that this view will eventually be attached to
 * @return A View corresponding to the data at the specified position.
 */
@Override
public View getView(int position, View scoreView, ViewGroup parent) {
    ViewHolder holder;
    if (inflater == null) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    if (scoreView == null) {

        scoreView = inflater.inflate(R.layout.list_row, parent, false);
        holder = new ViewHolder();
        holder.name = (TextView) scoreView.findViewById(R.id.name);
        holder.score = (TextView) scoreView.findViewById(R.id.score);

        scoreView.setTag(holder);

    } else {
        holder = (ViewHolder) scoreView.getTag();
    }

    final Items m = items.get(position);
    holder.name.setText(m.getName());
    holder.score.setText(m.getScore());

    return scoreView;
}

static class ViewHolder {

    TextView name;
    TextView score;

}

}

物品类

public class Items {

private String name, score;

public Items() {
}

public Items(String name, String score) {

    this.name = name;
    this.score = score;

}

public String getName() {
    return name;
}

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

public String getScore() {
    return score;
}

public void setScore(String score) {
    this.score = score;
}
}

list_row.xml

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

    android:layout_marginTop="502dp"
    android:paddingBottom="0dp"
    android:text="@string/button_OK" />
   </RelativeLayout>

实施此代码后，我能够创建一个球员水平列表及其各自的总得分。

得分板图像。

但是现在我想垂直显示它，以及每个回合的分数，因为我需要在每个回合之后显示每个球员的排名。就像下面的图片

任何有关实施新记分卡的建议都会很有帮助。
