android常用组件之Spinner

由 帅比萌擦擦* 提交于 2020-02-28 17:16:51
Spinner是下拉列表框，用户可以通过该控件从所列item中进行选择，还可以触发item的监听事件。 该实例通过ArrayAdapter类创建了含有30个item的下拉列表，当用户从所列的item中进行选择后，会弹出一个消息框，提示用户所选条目。注意spinner条目监听方法是setOnItemSelectedListener()，而不是setOnItemClickListener()，如果使用setOnItemClickListener()方法会出现秒退现象。 首先是布局文件，添加一个Spinner组件： <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/LinearLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="main.test_spinner.MainActivity" > <Spinner android:id="@+id/spinner1"
