微调不显示选定值 [英] Spinner does not show selected value

问题描述

我已经通过database.I填充数组列表可以得到并显示在我的微调阵列适配器数组列表实现了微调，但如果我在微调选择该项目并不在微调显示？我有什么错吗？

I have implemented the spinner by populating the array list through database.I can get and show the array list in my spinner array adapter but if I select the item in spinner it does not shown in spinner?What I had mistake here?

下面是我的code，

 Spinner spinner1 = (Spinner) findViewById(R.id.prospin);
     ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, providerlist);

  adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);

我通过使用该得到所选择的项目的字符串，

I get the selected item string by using this,

Spinner provid = (Spinner)findViewById(R.id.prospin);
String provider =provid.getSelectedItem().toString();

谁能帮我请！
