本文实例讲述了Android spinner下垃菜单用法。分享给大家供大家参考，具体如下：

一、使用数组作为数据源

1. 在layout布局文件：声明一个TextView控件和一个Spinner控件，代码如下

<Spinner android:id="@+id/Spinner01" android:layout_width="fill_parent" android:layout_height="wrap_content"></Spinner>

2. 在Activity文件加入以下代码

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); //将可选内容与ArrayAdapter连接起来 adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,m); //设置下拉列表的风格 adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); //将adapter 添加到spinner中 spinner.setAdapter(adapter); //添加事件Spinner事件监听 spinner.setOnItemSelectedListener(new SpinnerSelectedListener()); //设置默认值 spinner.setVisibility(View.VISIBLE); } //使用数组形式操作 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作为数据源

1. 在values文件夹下新建一个arryas.xml文件：代码如下

<"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>

2. 在Activity文件加入以下代码

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); //将可选内容与ArrayAdapter连接起来 adapter2 = ArrayAdapter.createFromResource(this, R.array.plantes, android.R.layout.simple_spinner_item); //设置下拉列表的风格 adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); //将adapter2 添加到spinner中 spinner2.setAdapter(adapter2); //添加事件Spinner事件监听 spinner2.setOnItemSelectedListener(new SpinnerXMLSelectedListener()); //设置默认值 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("你使用什么样的手机："+adapter2.getItem(arg2)); } public void onNothingSelected(AdapterView<?> arg0) { } } }

希望本文所述对大家Android程序设计有所帮助。
