这是我的代码：

pw.dismiss();
System.out.println(url1);

});
pw.showAtLocation(findViewById(R.id.merchantsimascard), Gravity.CENTER, 0, 0);
}
});
public class SpinnerKategori extends AsyncTask<Void, Void, String>{

return result;
}
@Override

try {
JSONObject jsonObject = new JSONObject(result);
JSONArray cat = jsonObject.getJSONArray("cat");
for (int i=0; i<cat.length();i++){
JSONObject status = cat.getJSONObject(i);
String Category=status.getString("name");
kategori.add(Category);
}
JSONArray city=jsonObject.getJSONArray("cit");

String kot = (String) city.get(j);
kota.add(kot);
}
}
catch (Exception e) {
Log.d("TEST CHART", e.getMessage());
}
}
}
我不知道如何找到我的错误，我希望有人能帮助我解决我的问题。谢谢!

保存“onCreate”上的上下文，替换MerchantSimasCard。这与McContext或使用UI线程有关
