spinner 下拉菜单 安卓源代码怎么注册用户
Spinner控件也是一种列表类型的控件，它的继承关系如下：
Java.lang.Object
? Android.view.View
? android.view.ViewGroup
? android.widget.AdapterViewTextends android.widget.Adapter
? android.widget.AbsSpinner
? android.widget.Spinner
android.widget.Spinner继承了android.view.ViewGroup类。
在Android的UI开发中，Spinner(下拉列表)总是可以用到的，一个简单的自定义Spinner制作我们只需要记住这重要的五步，一个Spinner就可以应用而生了。
求高手帮忙修改下拉菜单源码

如何打造Android自定义的下拉列表框控件
一、概述
Android中的有个原生的下拉列表控件Spinner，但是这个控件有时候不符合我们自己的要求，
比如有时候我们需要类似windows 或者web网页中常见的那种下拉列表控件，类似下图这样的：
这个时候只有自己动手写一个了。其实实现起来不算很难，
本文实现的方案是采用TextView +ImageView+PopupWindow的组合方案。
先来看看我们的自己写的控件效果图吧：（源码在文章下面最后给出哈！）
二、自定义下拉列表框控件的实现
1. 自定义控件用到的布局文件和资源：
结果框的布局页面：dropdownlist_view.xml:
?xml version="1.0" encoding="utf-8"?
RelativeLayout xmlns:android=""
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:id="@+id/compound"
android:background="@drawable/dropdown_bg_selector"
TextView
android:id="@+id/text"
android:layout_width="250dp"
android:layout_height="40dp"
android:paddingLeft="10dp"
android:text="文本文字"
android:gravity="center_vertical"
android:textSize="14sp"
android:padding="5dp"
android:singleLine="true" /
ImageView
android:id="@+id/btn"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_toRightOf="@+id/text"
android:src="@drawable/dropdown"
android:padding="5dp"
android:layout_centerVertical="true"
android:gravity="center"/
/RelativeLayout
下拉弹窗列表布局页面：dropdownlist_popupwindow.xml：
?xml version="1.0" encoding="utf-8"?
LinearLayout xmlns:android=""
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
ListView
android:id="@+id/listView"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:divider="#666666"
android:dividerHeight="1dp"
/ListView
/LinearLayout
selector资源文件：
dropdown_list_selector.xml：
?xml version="1.0" encoding="utf-8"?
selector xmlns:android=""
item android:state_pressed="true" android:drawable="@color/dropdownlist_item_press"/
item android:drawable="@color/dropdownlist_item"/
/selector
dropdown_bg_selector.xml：
?xml version="1.0" encoding="utf-8"?
selector xmlns:android=""
item android:state_pressed="true" android:drawable="@color/dropdownlist_press"/
item android:drawable="@color/dropdownlist_bg"/
/selector
2. 自定义下拉列表框控件类的实现：
我们采用了TextView+ImageView+PopupWindow的组合方案，所以我的自定义控件需要重写ViewGroup，由于我们已经知道了，布局方向为竖直方向，所以这里，
我直接继承LinearLayout来写这个控件。具体实现代码如下：
package com.czm.xcdropdownlistview;
import java.util.ArrayList;
import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.PopupWindow;
import android.widget.TextView;

public class XCDropDownListView extends LinearLayout{
private TextView editText;
private ImageView imageView;
private PopupWindow popupWindow = null;
private ArrayListString dataList = new ArrayListString();
private View mView;
public XCDropDownListView(Context context) {
this(context,null);
// TODO Auto-generated constructor stub
public XCDropDownListView(Context context, AttributeSet attrs) {
this(context, attrs,0);
// TODO Auto-generated constructor stub
public XCDropDownListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
initView();
public void initView(){
String infServie = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater layoutInflater;
layoutInflater = (LayoutInflater) getContext().getSystemService(infServie);
View view = layoutInflater.inflate(R.layout.dropdownlist_view, this,true);
editText= (TextView)findViewById(R.id.text);
imageView = (ImageView)findViewById(R.id.btn);
this.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(popupWindow == null ){
showPopWindow();
}else{
closePopWindow();
* 打开下拉列表弹窗
private void showPopWindow() {
// 加载popupWindow的布局文件
String infServie = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater layoutInflater;
layoutInflater = (LayoutInflater) getContext().getSystemService(infServie);
View contentView = layoutInflater.inflate(R.layout.dropdownlist_popupwindow, null,false);
ListView listView = (ListView)contentView.findViewById(R.id.listView);
listView.setAdapter(new XCDropDownListAdapter(getContext(), dataList));
popupWindow = new PopupWindow(contentView,LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
popupWindow.setBackgroundDrawable(getResources().getDrawable(R.color.transparent));
popupWindow.setOutsideTouchable(true);
popupWindow.showAsDropDown(this);
* 关闭下拉列表弹窗
private void closePopWindow(){
popupWindow.dismiss();
popupWindow = null;

* @param list
public void setItemsData(ArrayListString list){

* @author caizhiming
class XCDropDownListAdapter extends BaseAdapter{

@Override
public int getCount() {

return mData.size();
@Override

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
// 自定义视图
ListItemView listItemView = null;
if (convertView == null) {
// 获取list_item布局文件的视图
convertView = inflater.inflate(R.layout.dropdown_list_item, null);
listItemView = new ListItemView();
// 获取控件对象
listItemView.tv = (TextView) convertView
.findViewById(R.id.tv);
listItemView.layout = (LinearLayout) convertView.findViewById(R.id.layout_container);
// 设置控件集到convertView
convertView.setTag(listItemView);
} else {
listItemView = (ListItemView) convertView.getTag();
// 设置数据
listItemView.tv.setText(mData.get(position).toString());
final String text = mData.get(position).toString();
listItemView.layout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
editText.setText(text);
closePopWindow();
return convertView;
private static class ListItemView{
TextView tv;
LinearLayout layout;
三、如何使用该自定义下拉列表框控件
使用该控件和使用普通的自带的控件一样，首先需要在布局文件中引用该控件：
RelativeLayout xmlns:android=""
xmlns:tools=""
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.czm.xcdropdownlistview.MainActivity"
tools:ignore="MergeRootFrame"
com.czm.xcdropdownlistview.XCDropDownListView
android:id="@+id/drop_down_list_view"
android:layout_marginTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" /
/RelativeLayout
其次，就是在代码中使用该控件：
package com.czm.xcdropdownlistview;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
* 使用下拉列表框控件 示例
* @author caizhiming
public class MainActivity extends Activity {
XCDropDownListView dropDownListView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dropDownListView = (XCDropDownListView)findViewById(R.id.drop_down_list_view);
ArrayListString list = new ArrayListString();
for(int i = 0;i 6;i++){
list.add("下拉列表项"+(i+1));
dropDownListView.setItemsData(list);
对了，这个控件中，我没有实现点击item项回调接口，这个可能对有些写惯了回调的可能觉得少了写什么的感觉，有兴趣的你可以自己添加相关回调操作哈，这个大家应该都会把。
