列表新增列表項有兩種方法:，下面例子：
- spinner1通過android:entries指定了列表的項陣列
- spinner2通過ArrayAdapter介面卡使用陣列來確定列表項

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
 
 >

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:spinnerMode="dialog"
        android:prompt="@string/spinnerTitle"
        android:entries="@array/books" />

    <!-- 方法1：通過android:entries指定了列表的項陣列 -->
 

    <Spinner
        android:id="@+id/spinner2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:spinnerMode="dropdown" 
        android:dropDownVerticalOffset="5dp"/>

    <!-- 方法2：通過ArrayAdapter介面卡使用陣列來確定列表項 -->
    <TextView
        android:id
 
="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

</LinearLayout>

string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">SpinnerDemo</string>
    <string name="action_settings">Settings</string>
    <string name="spinnerTitle">請選擇</string>
    <string-array name="books">
        <item >Java基礎教程</item>
        <item >web開發專案實訓</item>
        <item >Android基礎教程</item>
        <item >計算機網路</item>
    </string-array>

</resources>

MainActivity.java

package com.example.spinnerdemo;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Spinner sp2 = (Spinner)findViewById(R.id.spinner2);
        final TextView tv = (TextView)findViewById(R.id.textView1);
        final String[] citys = new String[]{"北京","上海","廣州"};
        //建立介面卡，並設定給spinner2
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_list_item_1,citys);
        sp2.setAdapter(aa);
        //新增監聽器，監聽點選事件
        sp2.setOnItemSelectedListener(new OnItemSelectedListener(){
            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {
                tv.setText("選擇"+citys[position]);
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }

        });
    }
}
