注意：Spinner的setAdapter方法可以設置為ArrayAdapter和BaseAdapter的子類，可以不使用體統的選擇，這里可以根據自己的喜好自行設置
一、使用數組作為數據源
1.新建一個android的工程
2.工程的layout.xml文件如下：聲明一個TextView控件和一個Spinner控件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<TextView android:id="@+id/spinnerText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"></TextView>
<Spinner android:id="@+id/Spinner01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"></Spinner>
</LinearLayout>
3.java代碼
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
public class SpinnerActivity extends Activity {
private static final String[] m={"A型","B型","O型","AB型","其他"};
private TextView view ;
private Spinner spinner;
private ArrayAdapter<String> adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.spinner);
view = (TextView) findViewById(R.id.spinnerText);
spinner = (Spinner) findViewById(R.id.Spinner01);
//將可選內容與ArrayAdapter連接起來
adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,m);
//設置下拉列表的風格
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//將adapter 添加到spinner中
spinner.setAdapter(adapter);
//添加事件Spinner事件監聽
spinner.setOnItemSelectedListener(new SpinnerSelectedListener());
//設置默認值
spinner.setVisibility(View.VISIBLE);
}
//使用數組形式操作
class SpinnerSelectedListener implements OnItemSelectedListener{
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
view.setText("你的血型是："+m[arg2]);
}
public void onNothingSelected(AdapterView<?> arg0) {
}
}
}

二、使用XML作為數據源
1.新建一個android的工程
2.在values文件夾下新建一個arryas.xml文件：聲明一個TextView控件和一個Spinner控件，代碼如下：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="plantes">
<item>NOKIA</item>
<item>MOTO</item>
<item>HTC</item>
<item>LG</item>
<item>其他</item>
</string-array>
</resources>
3.java代碼
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
public class SpinnerActivity extends Activity {
private TextView view2;
private Spinner spinner2;
private ArrayAdapter adapter2;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.spinner);
spinner2 = (Spinner) findViewById(R.id.spinner02);
view2 = (TextView) findViewById(R.id.spinnerText02);
//將可選內容與ArrayAdapter連接起來
adapter2 = ArrayAdapter.createFromResource(this, R.array.plantes, android.R.layout.simple_spinner_item);
//設置下拉列表的風格
adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//將adapter2 添加到spinner中
spinner2.setAdapter(adapter2);
//添加事件Spinner事件監聽
spinner2.setOnItemSelectedListener(new SpinnerXMLSelectedListener());
//設置默認值
spinner2.setVisibility(View.VISIBLE);
}
//使用XML形式操作
class SpinnerXMLSelectedListener implements OnItemSelectedListener{
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
view2.setText("你使用什么樣的手機："+adapter2.getItem(arg2));
}
public void onNothingSelected(AdapterView<?> arg0) {
}
}
}
