编辑：拼错了适配器。还将所有这些字符串存储在一个数组中，这样更好更清洁。

的简单拼写错误
adaptor还考虑使用ArrayList存储所有这些字符串
答案 1 :(得分：1)
你有2个错误的拼写。根据您为适配器命名的方式，首先.setAdaptor它应该是.setAdapter秒在方括号(customAdaper)内它应该是(customAdapter)。使用Android Studio Intellisense可以避免错误拼写。
还可以考虑使用数组或列表来简化代码。并在AsyncTask中覆盖postExecute方法并在那里填充适配器。像这样：
@Override
protected void onPostExecute(Void aVoid) {
CustomAdapter customAdapter = new CustomAdapter();
lista.setAdapter(customAdapter);
}
