想到Spinner下拉按钮可以通过两种方法生成

方法一:

1、在array数组里面定义数组

代码如下:

<resources>
    <st
<?xml version="1.0" encoding="utf-8"?>
ring-array name="balls">
        <item >篮球</item>
        <item >足球</item>
        <item >网球</item>
        <item >排球</item>
    </string-array>
    
        <string-array name="citys">
        <item >北京</item>
        <item >上海</item>
        <item >大连</item>
        <item >合肥</item>
         <item >安徽</item>
    </string-array>
    
</resources>

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

2、在spinner布局下,将数组应用过来

     代码如下:

   <Spinner
       android:id="@+id/spinner"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_toRightOf="@+id/city"
       android:entries="@array/citys"
       android:prompt="@string/city" />

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

3、再在.java中定义声明,然后用其本身的方法获得其值

代码如下:

private Spinner citySpinner;
citySpinner = (Spinner)findViewById(R.id.spinner);
 
    //从spinner 下拉框中获取选择的值
protected String getCitys() {
        // TODO Auto-generated method stub
     return citySpinner.getSelectedItem().toString();
    }

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

方法二:

1、在Spinner的布局文件里面先定义,但不要有值。

<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/city"
android:id="@+id/cityItems">
</Spinner>

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

2、定义数组和Spinner

private static final String[] cities = { "北京", "上海", "广州", "郑州" };

private Spinner cityItems;

3、将定义的Spinne与布局文件中的id挂钩

cityItems = (Spinner) findViewById(R.id.cityItems);

4、创建一个数组型适配器并将cities中的数据与系统默认的spinner布局文件中的元素挂钩

ArrayAdapter<String> adpter = new ArrayAdapter<String>(

LoginActivity.this,android.R.layout.simple_spinner_item,cities);

5、将此适配器adpter设置为setdropdownviewresource的模式

(Sets the layout resource to create the drop down views)

adpter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

6、将文件中定义的Spinner与适配器建立联系

cityItems.setAdapter(adpter);

  private    String[]   cityItems;
setContentView(R.layout.main);
        
Spinner spinner = (Spinner) findViewById(R.id.cityItems);
        
cityItems = getResources().getStringArray(R.array.citys);
ArrayAdapter< String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item,cityItems);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
Toast.makeText(MainActivity.this, "您选择的是"+ spinner.getSelectedItem().toString(), 2000).show();

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
