java - 列表中按钮的 onclicklistener

Question

我在 android studio 中有一个带有自定义 ListView 的项目。我的自定义 ListView 包含 2textbox 和一个开关和 imagebutton 但我无法找到如何在 listadapter 类中为它们设置 onclicklistener 或其他监听器

这是我的列表适配器:

public class listadapter extends ArrayAdapter {
    Context context_;
    int resource_;
    ArrayList<reminders> objects_;
    boolean bool;
    DBAdapter db;

    public listadapter(Context context, int resource, ArrayList<reminders> objects) {
        super(context, resource, objects);
        context_ = context;
        resource_ = resource;
        objects_ = objects;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context_.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View ViewRow = inflater.inflate(R.layout.reminders_list_layout, parent, false);
        TextView nametxt, addresstxt;
        Switch sw;
        ImageView imgview;
        nametxt = (TextView) ViewRow.findViewById(R.id.remindername);
        addresstxt = (TextView) ViewRow.findViewById(R.id.reminderaddress);
        sw = (Switch) ViewRow.findViewById(R.id.remindersw);
        imgview = (ImageView) ViewRow.findViewById(R.id.imageView4);
        nametxt.setText(objects_.get(position).name);
        addresstxt.setText(objects_.get(position).address);
        bool = (objects_.get(position).swbool != 0);
        sw.setChecked(bool);
        imgview.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                View parentRow = (View) v.getParent();
                ListView listView = (ListView) parentRow.getParent();
                final int position = listView.getPositionForView(parentRow);
                Toast.makeText(context_,position+"",Toast.LENGTH_LONG).show();
            }
        });
        return ViewRow;
    }

但是当我测试我的项目并单击 imageview 时，它会强制关闭并且 logcat 中出现此错误

java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.ListView at com.amir_p.yadambendaz.listadapter$1.onClick(listadapter.java:49)

我能做什么？

尝试改变

public View getView(int position, View convertView, ViewGroup parent) {
    ...
    @Override
    public void onClick(View v) {
        View parentRow = (View) v.getParent();
        ListView listView = (ListView) parentRow.getParent();
        ...
}

到

public View getView(int position, View convertView, final ViewGroup parent) {
    ...
    @Override
    public void onClick(View v) {
        ListView listView = (ListView) parent;
        ...
}
