1、准备两张图片，并做好9.png

2、在drawable中定义my_spinner.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@drawable/spinner_press" android:state_pressed="true"></item>    <!-- 按下时效果 -->    <item android:drawable="@drawable/spinner" android:state_pressed="false"> <!-- 默认效果 -->    </item></selector>

3.写activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"       tools:context=".MainActivity" >    <Spinner        android:id="@+id/sp_prentClass"        android:layout_width="match_parent"        android:layout_height="60dp"        android:layout_marginBottom="10dp"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="10dp"        android:animationCache="true"        android:background="@drawable/my_spinner"        android:drawSelectorOnTop="true"        android:dropDownVerticalOffset="-10dp"        android:popupBackground="@drawable/spinner_dropdown"        android:requiresFadingEdge="none"        android:spinnerMode="dropdown" /></LinearLayout>

4.在layout中定义simple_spinner_item.xml

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@android:id/text1"    android:layout_width="fill_parent"    android:layout_height="50dp"    android:gravity="center_vertical"     android:textSize="18sp"    android:singleLine="true"    android:paddingLeft="10dp"    android:textColor="#808080" />

5、java代码

package com.example.myspinner;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.Spinner;public class MainActivity extends Activity {private Spinner sp;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.simple_spinner_item); // 设置下拉的每一项的样式// 设置下拉方式adapter.setDropDownViewResource(R.layout.simple_spinner_item);for (int i = 0; i < 10; i++) {adapter.add("测试测试" + i);}sp = (Spinner) findViewById(R.id.sp_prentClass);sp.setAdapter(adapter);}}

我写的是适配平板的显示的效果如下 :

自己查一天资料写的经验有限大神勿喷.
