是的，您可以通过setOnItemSelectedListener()注册一个侦听器，如下所示。

当某些东西被选中时，Spinner应该触发一个"OnItemSelected"事件:

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        Object item = parent.getItemAtPosition(pos);
    }
    public void onNothingSelected(AdapterView<?> parent) {
    }
});

Spinner mySpinner = (Spinner) findViewById(R.id.your_spinner);
String text = mySpinner.getSelectedItem().toString();

View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();

如果你已经知道项目是一个字符串，我更喜欢:

String itemText = (String) mySpinner.getSelectedItem();

在一个你知道是字符串的对象上调用toString()似乎比仅仅将对象转换为字符串更迂回。

说这是你的xml与旋转条目(即。标题)和价值:

<resources>
    <string-array name="size_entries">
        <item>Small</item>
        <item>Medium</item>
        <item>Large</item>
    </string-array>

    <string-array name="size_values">
        <item>12</item>
        <item>16</item>
        <item>20</item>
    </string-array>
</resources>

这是你的旋转器:

<Spinner
    android:id="@+id/size_spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:entries="@array/size_entries" />

然后在代码中获取条目:

Spinner spinner = (Spinner) findViewById(R.id.size_spinner);
String size = spinner.getSelectedItem().toString(); // Small, Medium, Large

为了得到这些值:

int spinner_pos = spinner.getSelectedItemPosition();
String[] size_values = getResources().getStringArray(R.array.size_values);
int size = Integer.valueOf(size_values[spinner_pos]); // 12, 16, 20

将setOnItemSelectedListener添加到spinner引用中，并获得这样的数据

 mSizeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
            selectedSize=adapterView.getItemAtPosition(position).toString();
