Android 使用改装2填充ListView

我试图用服务器上的JSON填充ListView。我正在从服务器获取数据，但我似乎不知道如何将其放在ListView中。我得到的错误在onResponse中

它说：“错误：（84，54）错误：类jucatoriliberiaryadapter中的构造函数jucatoriliberiaryadapter不能应用于给定的类型； 必需：上下文，ArrayList 找到：碎片活动，呼叫> 原因：无法通过方法调用转换将实际参数调用>转换为ArrayList“

我想我已经尝试了几乎所有的Alt+Enter修复。还尝试将

onResponse（）中的
Call类型更改为
onResponse（）
如果适配器需要
列表
，则response参数是您要给适配器的玩家列表

请尝试以下代码：

final Call<List<FreePlayers>> request = REST_CLIENT.getFreePlayers(1);

request.enqueue(new Callback<List<FreePlayers>>() {

    @Override
    public void onResponse(final Call<List<FreePlayers>> call, final Response<List<FreePlayers>> response) {

        ArrayList<FreePlayers> players = null;

        players = response.body();

        ListView lv = (ListView) getView().findViewById(android.R.id.list);

        JucatoriLiberiArrayAdapter adapter = new JucatoriLiberiArrayAdapter(getActivity(),
                        players);

        lv.setAdapter(adapter);


    }

    @Override
    public void onFailure(final Call<FreePlayers> call, final Throwable t) {

    }
});

final Call request=REST\u CLIENT.getFreePlayers（1）；
request.enqueue（新回调（）{
@凌驾
公共void onResponse（最终呼叫，最终响应）{
ArrayList players=null；
players=response.body（）；
ListView lv=（ListView）getView（）.findViewById（android.R.id.list）；
jucatoriliberiarayadapter=新的jucatoriliberiarayadapter（getActivity（），
球员）；
低压设置适配器（适配器）；
}
@凌驾
失败时公共无效（最终呼叫、最终可丢弃t）{
}
});
呼叫与玩家关联，但玩家类型为
ArrayList
，呼叫类型为您要声明的
call

Call<FreePlayers>, 

public class JucatoriLiberiArrayAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<FreePlayers> players;




    public JucatoriLiberiArrayAdapter(Context context, ArrayList<FreePlayers> playersList) {

        this.context = context;
