一、使用方法

1、在layout中创建Spinner控件

<Spinner android:id="@+id/spinner1"android:layout_width="match_parent"android:layout_height="wrap_content"/>

2、给数据适配器添加数据源和显示格式

String[] city=new String[]{"北京","上海","香港","澳门"};ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, city);

3、给Spinner控件添加数据适配器

spinner1.setAdapter(adapter);

二、效果图及代码

package fry;import com.example.SpinnerDemo.R;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.Spinner;public class Activity01 extends Activity{ private Spinner spinner1; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity01); spinner1=(Spinner) findViewById(R.id.spinner1); initSpinner1(); } public void initSpinner1(){ String[] city=new String[]{"北京","上海","香港","澳门"}; ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, city); spinner1.setAdapter(adapter); }}
