Android ArrayAdapter getItem（）是不兼容的类型？

Question

我正在努力让我的ArrayAdapter工作 - 之前一直使用自定义ArrayAdapter没有问题，但这次我不确定发生了什么。

我正在尝试使用适配器创建ListView，该适配器将显示每个WeekViewEvent对象的两个字符串（mName，mLocation）：

public class WeekViewEvent implements Serializable{
private long mId;
private Calendar mStartTime;
private Calendar mEndTime;
private String mName;
private String mLocation;
private int mColor;
private boolean mAllDay;
private Shader mShader;
//construcotrs, setters, getters

ArrayAdapter：

  public class TEventAdapter extends ArrayAdapter<Testowa> {

    public TEventAdapter (Context context, ArrayList<Testowa> testowyeventarray){
        super(context, 0, testowyeventarray);}

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        View pojedynczyItemView = convertView;
        if(pojedynczyItemView==null){
            pojedynczyItemView = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false);
        }

        WeekViewEvent wvevent = getItem(position);

        TextView tv1 = (TextView) pojedynczyItemView.findViewById(R.id.tv_lv1);
        tv1.setText(wvevent.getName());
        TextView tv2 = (TextView) pojedynczyItemView.findViewById(R.id.tv_lv2);
        tv2.setText(wvevent.getLocation());

        return pojedynczyItemView;
    }
}

但AndroidStudio突出显示我将对象位置WeekViewEvent wvevent = getItem(position);视为不兼容类型的部分（下图）：

我卡住了：/你有什么想法我的代码有什么问题吗？ 谢谢你提前！

这应该有效

将Testowa更改为 - ＆gt; Testowa

public TEventAdapter（Context context，ArrayList＆lt; public class TEventAdapter extends ArrayAdapter<WeekViewEvent> { public TEventAdapter (Context context, ArrayList<WeekViewEvent> weekVieweEvent){ super(context, 0, weekVieweEvent);} @NonNull @Override public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { View pojedynczyItemView = convertView; if(pojedynczyItemView==null){ pojedynczyItemView = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false); } WeekViewEvent wvevent = getItem(position); TextView tv1 = (TextView) pojedynczyItemView.findViewById(R.id.tv_lv1); tv1.setText(wvevent.getName()); TextView tv2 = (TextView) pojedynczyItemView.findViewById(R.id.tv_lv2); tv2.setText(wvevent.getLocation()); return pojedynczyItemView; } } ＆gt; testowyeventarray）

公共类TEventAdapter扩展了ArrayAdapter＆lt; git push -u origin master error: src refspec master does not match any.＆gt;

$(".classname").bind("change paste keyup", function() {
    if ($("#fname").val() && $("#yourMessage").val()) { 
        $( "#Send" ).prop( "disabled", false ); 
    } else {
        $( "#Send" ).prop( "disabled", true );
    }
});
