我可能在帖子上回答得太迟了，但是我设法实现了这一点，使用Android数据绑定库Android Databinding。我创建了一个自定义绑定，以确保监听器不被调用，直到选定的项目被改变，所以即使用户选择相同的位置，一遍又一遍地事件不会被触发。

布局xml文件

    <layout>
  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/activity_vertical_margin"
xmlns:app="http://schemas.android.com/apk/res-auto">


<Spinner
    android:id="@+id/spinner"
    android:layout_width="150dp"
    android:layout_height="wrap_content"
    android:spinnerMode="dropdown"
    android:layout_below="@id/member_img"
    android:layout_marginTop="@dimen/activity_vertical_margin"
    android:background="@drawable/member_btn"
    android:padding="@dimen/activity_horizontal_margin"
    android:layout_marginStart="@dimen/activity_horizontal_margin"
    android:textColor="@color/colorAccent"
    app:position="@{0}"
    />
 </RelativeLayout>
 </layout>

App:position是你传递要选择的位置。

定制绑定

  @BindingAdapter(value={ "position"}, requireAll=false)
  public static void setSpinnerAdapter(Spinner spinner, int selected) 
  {

    final int [] selectedposition= new int[1];
    selectedposition[0]=selected;


    // custom adapter or you can set default adapter
        CustomSpinnerAdapter customSpinnerAdapter = new CustomSpinnerAdapter(spinner.getContext(), <arraylist you want to add to spinner>);
        spinner.setAdapter(customSpinnerAdapter);
            spinner.setSelection(selected,false);


    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            String item = parent.getItemAtPosition(position).toString();
        if( position!=selectedposition[0]) {
                        selectedposition[0]=position;
            // do your stuff here
                    }
                }


        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });
}

你可以阅读更多关于自定义数据绑定在这里Android自定义Setter

NOTE

不要忘记在Gradle文件中启用数据绑定 android { ．... 数据绑定{ Enabled = true ｝ ｝ 包括你的布局文件在<layout>标签

这是我最后的简单易用的解决方案:

public class ManualSelectedSpinner extends Spinner {
    //get a reference for the internal listener
    private OnItemSelectedListener mListener;

    public ManualSelectedSpinner(Context context) {
        super(context);
    }

    public ManualSelectedSpinner(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ManualSelectedSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setOnItemSelectedListener(@Nullable OnItemSelectedListener listener) {
        mListener = listener;
        super.setOnItemSelectedListener(listener);
    }

    public void setSelectionWithoutInformListener(int position){
        super.setOnItemSelectedListener(null);
        super.setSelection(position);
        super.setOnItemSelectedListener(mListener);
    }

    public void setSelectionWithoutInformListener(int position, boolean animate){
        super.setOnItemSelectedListener(null);
        super.setSelection(position, animate);
        super.setOnItemSelectedListener(mListener);
    }
}

使用默认的setSelection(…)作为默认行为，或者使用setSelectionWithoutInformListener(…)在旋转器中选择一个项目而不触发OnItemSelectedListener回调。

我将在创建onClickListener对象期间存储初始索引。

   int thisInitialIndex = 0;//change as needed

   myspinner.setSelection(thisInitialIndex);

   myspinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

      int initIndex = thisInitialIndex;

      @Override
      public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
         if (id != initIndex) { //if selectedIndex is the same as initial value
            // your real onselecteditemchange event
         }
      }

      @Override
      public void onNothingSelected(AdapterView<?> parent) {
      }
  });

已经有很多答案了，这是我的。

我扩展了AppCompatSpinner，并添加了一个方法pgmSetSelection(int pos)，允许编程选择设置，而不触发选择回调。我用RxJava编写了这个代码，这样选择事件就可以通过Observable传递。

package com.controlj.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.AdapterView;

import io.reactivex.Observable;

/**
 * Created by clyde on 22/11/17.
 */

public class FilteredSpinner extends android.support.v7.widget.AppCompatSpinner {
    private int lastSelection = INVALID_POSITION;


    public void pgmSetSelection(int i) {
        lastSelection = i;
        setSelection(i);
    }

    /**
     * Observe item selections within this spinner. Events will not be delivered if they were triggered
     * by a call to setSelection(). Selection of nothing will return an event equal to INVALID_POSITION
     *
     * @return an Observable delivering selection events
     */
    public Observable<Integer> observeSelections() {
        return Observable.create(emitter -> {
            setOnItemSelectedListener(new OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                    if(i != lastSelection) {
                        lastSelection = i;
                        emitter.onNext(i);
                    }
                }

                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {
                    onItemSelected(adapterView, null, INVALID_POSITION, 0);
                }
            });
        });
    }

    public FilteredSpinner(Context context) {
        super(context);
    }

    public FilteredSpinner(Context context, int mode) {
        super(context, mode);
    }

    public FilteredSpinner(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FilteredSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public FilteredSpinner(Context context, AttributeSet attrs, int defStyleAttr, int mode) {
        super(context, attrs, defStyleAttr, mode);
    }
}

它的用法示例，在Fragment中调用onCreateView()，例如:

    mySpinner = view.findViewById(R.id.history);
    mySpinner.observeSelections()
        .subscribe(this::setSelection);

其中setSelection()是封闭视图中的一个方法，看起来像这样，它既可以通过可观察对象从用户选择事件中调用，也可以在其他地方以编程方式调用，因此处理选择的逻辑对于两个选择方法来说是通用的。

private void setSelection(int position) {
    if(adapter.isEmpty())
        position = INVALID_POSITION;
    else if(position >= adapter.getCount())
        position = adapter.getCount() - 1;
    MyData result = null;
    mySpinner.pgmSetSelection(position);
    if(position != INVALID_POSITION) {
        result = adapter.getItem(position);
    }
    display(result);  // show the selected item somewhere
}

不幸的是，解决这个问题的两个最常见的建议解决方案，即统计回调发生次数和发布Runnable以在稍后设置回调，在启用可访问性选项时都可能失败。下面是一个帮助类，它可以解决这些问题。进一步的解释在评论区。

/**
 * Spinner Helper class that works around some common issues 
 * with the stock Android Spinner
 * 
 * A Spinner will normally call it's OnItemSelectedListener
 * when you use setSelection(...) in your initialization code. 
 * This is usually unwanted behavior, and a common work-around 
 * is to use spinner.post(...) with a Runnable to assign the 
 * OnItemSelectedListener after layout.
 * 
 * If you do not call setSelection(...) manually, the callback
 * may be called with the first item in the adapter you have 
 * set. The common work-around for that is to count callbacks.
 * 
 * While these workarounds usually *seem* to work, the callback
 * may still be called repeatedly for other reasons while the 
 * selection hasn't actually changed. This will happen for 
 * example, if the user has accessibility options enabled - 
 * which is more common than you might think as several apps 
 * use this for different purposes, like detecting which 
 * notifications are active.
 * 
 * Ideally, your OnItemSelectedListener callback should be
 * coded defensively so that no problem would occur even
 * if the callback was called repeatedly with the same values
 * without any user interaction, so no workarounds are needed.
 * 
 * This class does that for you. It keeps track of the values
 * you have set with the setSelection(...) methods, and 
 * proxies the OnItemSelectedListener callback so your callback
 * only gets called if the selected item's position differs 
 * from the one you have set by code, or the first item if you
 * did not set it.
 * 
 * This also means that if the user actually clicks the item
 * that was previously selected by code (or the first item
 * if you didn't set a selection by code), the callback will 
 * not fire.
 * 
 * To implement, replace current occurrences of:
 * 
 *     Spinner spinner = 
 *         (Spinner)findViewById(R.id.xxx);
 *     
 * with:
 * 
 *     SpinnerHelper spinner = 
 *         new SpinnerHelper(findViewById(R.id.xxx))
 *         
 * SpinnerHelper proxies the (my) most used calls to Spinner
 * but not all of them. Should a method not be available, use: 
 * 
 *      spinner.getSpinner().someMethod(...)
 *
 * Or just add the proxy method yourself :)
 * 
 * (Quickly) Tested on devices from 2.3.6 through 4.2.2
