1.资源文件生成

android:id="@+id/spner"

android:prompt="@string/city_prompt"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:entries="@array/mycity"/>

资源文件

encoding="utf-8"?>

北京

上海

广州

宜昌

2.Activity生成下拉列表

android:id="@+id/myedu"

android:layout_width="fill_parent"

android:layout_height="wrap_content"/>

资源文件

encoding="utf-8"?>

name="myedu_labels">

JAVA源文件

public class Hello extends Activity {

private Spinner sper=null;

private ArrayAdapter

adapterEdu=null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

this.sper=(Spinner) super.findViewById(R.id.myedu);

this.adapterEdu=ArrayAdapter.createFromResource(this,

R.array.myedu_labels,

android.R.layout.simple_spinner_item);

this.adapterEdu.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

this.sper.setAdapter(this.adapterEdu);

}

}

3.动态生成下拉列表

public class Hello extends Activity {

private Spinner sperColor=null;

private ArrayAdapter

adapterColor=null;

private List

listColor=null;

protected void onCreate(Bundle savedInstanceState) {

this.sperColor=(Spinner)super.findViewById(R.id.myclo);

this.listColor=new

ArrayList();

this.listColor.add("红色");

this.listColor.add("黄色");

this.listColor.add("蓝色");

this.adapterColor=new

ArrayAdapter(this,

android.R.layout.simple_spinner_item,

this.listColor);

this.adapterColor.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

this.sperColor.setAdapter(this.adapterColor);

}
