我的JSON响应以一个JSON数组开始，其中进一步包含三个数组。我想在卡片视图中显示这些阵列的内容。似乎在每个循环中，我总是在更改同一ViewHolder，因此结果始终是最后一个循环的最后一项。 int i中的onBindViewHolder表示要显示的项目的位置。

我的Onbindviewholder类，我尝试过此代码，但是在我的所有名片视图中都显示相同的详细信息
@Override
public void onBindViewHolder(@NonNull footballmatchadapter.ViewHolder viewHolder, int i) {

secondTeamLastResults = post.getSecondTeamLastResults();

这是我的ongetItemCount函数，它返回所有三个数组的大小之和
@Override
public int getItemCount() {
int v1 = post.getFirstTeamVSSecondTeam() != null ?
post.getFirstTeamVSSecondTeam().size() : 0;
int v2 = post.getFirstTeamLastResults() != null ?
post.getFirstTeamLastResults().size() : 0;
int v3 = post.getSecondTeamLastResults() != null ?
post.getSecondTeamLastResults().size() : 0;
return v1 + v2 + v3;
}
答案 0 :(得分：1)
首先，似乎每个结果列表都不需要一个不同的类。您应该创建一个像这样的类：
public class MatchResults {
@SerializedName("match_id")
private long matchId;
@SerializedName("country_id")
private long countryId;
@SerializedName("country_name")
private String countryName;
...
}
您的适配器应如下所示：
public class FootballMatchAdapter extends RecyclerView.Adapter<FootballMatchAdapter.ViewHolder> {
private List<MatchResults> firstTeamVSSecondTeams;
private List<MatchResults> firstTeamLastResults;
private List<MatchResults> secondTeamLastResults;
public FootbalMatchAdapter() {
loadData();
}
private void loadData() {
firstTeamVSSecondTeams = post.getFirstTeamVSSecondTeam();
firstTeamLastResults = post.getFirstTeamLastResults();
secondTeamLastResults = post.getSecondTeamLastResults();
}
private int getFirstTeamVSSecondTeamsSize() {
return (firstTeamVSSecondTeams != null ?
firstTeamVSSecondTeams.size() : 0);
}
private int getFirstTeamLastResultsSize() {
return (firstTeamLastResults != null ?
firstTeamLastResults.size() : 0);
}
private int getSecondTeamLastResultsSize() {
return (secondTeamLastResults != null ?
secondTeamLastResults.size() : 0);
}
@Override
public int getItemCount() {
return getFirstTeamVSSecondTeamsSize()
+ getFirstTeamLastResultsSize()
+ getSecondTeamLastResultsSize();
}
private MatchResults getItem(int i) {
if (i < 0 || i > getItemCount())
return null;
if (i >= (getFirstTeamVSSecondTeamsSize() + getFirstTeamLastResultsSize())) {
int pos = i - (getFirstTeamVSSecondTeamsSize() + getFirstTeamLastResultsSize());
return secondTeamLastResults.get(pos);
}
else if (i >= getFirstTeamVSSecondTeamsSize()) {
int pos = i - getFirstTeamVSSecondTeamsSize();
return firstTeamLastResults.get(pos);
}
else {
return firstTeamVSSecondTeams.get(i);
}
}
@Override
public FootballMatchAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
...
}
@Override
public void onBindViewHolder(@NonNull footballmatchadapter.ViewHolder
viewHolder, int i) {
String leauge = "", date = "", team1 = "", team2 = "", team1score = "", team2score = "";
MatchResult result = getItem(i);
leauge = firstTeamVSSecondTeam.getLeagueName();
date = "Match Date " + firstTeamVSSecondTeam.getMatchDate();
team1 = "Home Team " + firstTeamVSSecondTeam.getMatchHometeamName();
team2 = "Second Team " + firstTeamVSSecondTeam.getMatchAwayteamName();
team1score = firstTeamVSSecondTeam.getMatchHometeamName() + " : "+firstTeamVSSecondTeam.getMatchHometeamScore();
team2score = firstTeamVSSecondTeam.getMatchAwayteamName() + " : "+firstTeamVSSecondTeam.getMatchAwayteamScore();
viewHolder.tvleague.setText(leauge);
viewHolder.tvdate.setText(date);
viewHolder.tvhometownteam.setText(team1);
viewHolder.tvawayteam.setText(team2);
viewHolder.tvhometeamscore.setText(team1score);
viewHolder.tvawayteamscore.setText(team2score);
}
public static class ViewHolder extends RecyclerView.ViewHolder {
...
}
}
我没有运行此代码，因此可能有一些错误。
