spinner1.setOnItemSelectedListener(
    new AdapterView.OnItemSelectedListener() {
        //add some code here
    }
);

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

spnLocale.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { 
        // Your code here
    } 

    public void onNothingSelected(AdapterView<?> adapterView) {
        return;
    } 
}); 

注意:记住一件事。

OnItemSelectedListener事件将执行两次:

旋转器初始化 手动选择的用户

试着用标志变量来区分这两者。

如果你想要一个true onChangedListener()。将初始值存储在处理程序中，并检查它是否已更改。它很简单，不需要全局变量。如果页面上有多个转轮，则有效。

String initialValue = // get from Database or your object
mySpinner.setOnItemSelectedListener(new SpinnerSelectedListener(initialValue));

...

protected class SpinnerSelectedListener implements AdapterView.OnItemSelectedListener {

        private SpinnerSelectedListener() {
            super();
        }

        public SpinnerSelectedListener(String initialValue) {
            this();
            this.initialValue = initialValue;
        }

        private String initialValue;

        // getter and setter removed.  

        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            final String newValue = (String) spinHeight.getItemAtPosition(position);
            if (newValue.equals(initialValue) == false) {
               // Add your code here.  The spinner has changed value. 

               // Maybe useful.   
               // initialValue = newValue;
            }

        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
               // Maybe useful.   
               // initialValue = null; 
        }
    }

对象是你的朋友，使用它们。

前面的一些答案是不正确的。它们适用于其他小部件和视图，但Spinner小部件的文档明确指出:

旋转器不支持项目单击 事件。调用此方法将引发 一个例外。

最好使用OnItemSelectedListener()代替:

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // your code here
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // your code here
    }

});

这对我很有用。

注意，onItemSelected方法也被调用时，视图正在构建，所以你可以考虑把它放在onCreate()方法调用。

找到你的微调器名称和id，然后实现这个方法。

spinnername.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // your code here
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // your code here
    }
});

spinner.setOnItemSelectedListener(
            new AdapterView.OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> arg0, View arg1,
                        int arg2, long arg3) {

                    // TODO Auto-generated method stub
                }

                @Override
                public void onNothingSelected(AdapterView<?> arg0) {
                    // TODO Auto-generated method stub

                }
                //add some code here
            }
        );
