关于如何设置微调器的内容，我在这里已经关注了很多问题，但没有一个对我有用，我仍然会收到错误。
这是布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"

</LinearLayout>
没有什么花哨的东西，只有textview作为微调器的标签，微调器本身和一对按钮，要么选择微调器选项，要么取消选择和ArrayAdapter构造函数上请求的textview。不知道为什么，我看到的每个教程，ArrayAdapter构造函数都询问上下文，Spinner ID和内容，但是对于我得到的，请求Context，TextViewID和内容

代码只是从webService中提取信息，将其存储在String数组中，然后传递给ArrayAdapter以将其设置为Spinner。

希望你能帮助我，因为我在互联网上找到的一切都没有帮助我
编辑1：嗯，我至少设法显示现在的布局，但现在它向我展示了旋转器空，以及bouth按钮什么都不做。
答案 0 :(得分：1)
这是我的微调器标签的样子：
<Spinner
android:id="@+id/my_transtype_spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="true"
android:textSize="12sp"
android:prompt="Choose a value" />
然后您的类需要扩展Android API Activity类。 在onCreate中，执行以下操作：
// spinner boxes code
spnrMySpinner = (Spinner) findViewById(R.id.my_transtype_spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.trans_types, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnrMySpinner.setAdapter(adapter);
