我认为最好的方法是让flagitemselected = 0;在onCreate()。在itemselected event上增加标志，即flagitemselected++;然后检查

if(flagitemselected!=1)
{
// do your work here
}

我想这会有帮助。

这是可行的 初始化旋转器和findviewbyid并使用它将工作

    Spinner schemeStatusSpinner;

  schemeStatusSpinner = (Spinner) dialog.findViewById(R.id.spinner);

schemeStatusSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            // your code here
            if(schemeStatusSpinner.getSelectedItemId()==4){
                reasonll.setVisibility(View.VISIBLE);
            }
            else {
                reasonll.setVisibility(View.GONE);
            }
        }

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

    });

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
    }
});

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

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。
