嗨在我的应用程序中我创建了一个form.in第一个是intial是android中的spinner这些来自数据库的初始字段值我希望将这些值显示到intiial spinner但是值不显示到数据库中。为此我我创建了名为getpatient.php的php文件，只有我得到了微调器值。
任何人都可以帮助我。

答案 0 :(得分：0)
你是在字符串数组initial []中插入值吗？...但是你要添加列表数据
List<String> list = new ArrayList<String>();
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
(getApplicationContext(), android.R.layout.simple_spinner_item, list);
虽然列表中没有任何内容......所以它将被设置为空..
尝试这样做..
替换==＆gt; final String[] intial = new String[JA.length()];与
List<String> list = new ArrayList<String>();
并将您的数据添加到此列表中： -
list.add(json.getString("initial_name"));
然后添加数据适配器。并将适配器设置为微调器。
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
(getApplicationContext(), android.R.layout.simple_spinner_item, list);
