只是为了补充使用onTouchListener来区分对setOnItemSelectedListener的自动调用(这是Activity初始化的一部分，等等)与实际用户交互触发的对它的调用之间的提示，在尝试了其他一些建议后，我做了以下工作，并发现它用最少的代码行就能很好地工作。

只需要为你的Activity/Fragment设置一个布尔字段:

private Boolean spinnerTouched = false;

然后在你设置你的旋转器的setOnItemSelectedListener之前，设置一个onTouchListener:

    spinner.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            System.out.println("Real touch felt.");
            spinnerTouched = true;
            return false;
        }
    });

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    ...
         if (spinnerTouched){
         //Do the stuff you only want triggered by real user interaction.
        }
        spinnerTouched = false;

这不是一个完美的解决方案，但如果你喜欢将起始字符串作为一个占位符，你可以添加占位符弹簧值("Day_of_Work_Out")

  @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            String name = (String) parent.getItemAtPosition(position);
            if (name.equals("Day_of_Work_Out")) {

            }else {

                workOutD = name;
                Intent intent = new Intent();
                workOutNam = workOutName.getText().toString();

                if (workOutNam == null) {

                    startActivity(intent);
                    Log.i("NewWorkOutActivity","Name is null");

                }else {
                    Log.i("NewWorkOutActivity","Name Not null");
                    Toast.makeText(NewWorkOutActivity.this, "Please Select a Day", Toast.LENGTH_LONG).show();
                }


            }
        }

mYear.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View arg1, int item, long arg3) {
                if (mYearSpinnerAdapter.isEnabled(item)) {

                }
            }

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

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。

import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.Spinner;
import android.widget.SpinnerAdapter;

/**
 * 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

public class SpinnerHelper implements OnItemSelectedListener {
    private final Spinner spinner;

    private int lastPosition = -1;
    private OnItemSelectedListener proxiedItemSelectedListener = null;  

    public SpinnerHelper(Object spinner) {
         this.spinner = (spinner != null) ? (Spinner)spinner : null;

    }

    public void setOnItemSelectedListener(OnItemSelectedListener listener) {
        proxiedItemSelectedListener = listener;
        spinner.setOnItemSelectedListener(listener == null ? null : this);
    }   

    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            }
        }
    }

    public void onNothingSelected(AdapterView<?> parent) {
        if (-1 != lastPosition) {
            lastPosition = -1;
            if (proxiedItemSelectedListener != null) {
                proxiedItemSelectedListener.onNothingSelected(
                        parent
                );
            }
        }
    }

    public void setAdapter(SpinnerAdapter adapter) {
        if (adapter.getCount() > 0) {
            lastPosition = 0;
        }
        spinner.setAdapter(adapter);
    }

    public SpinnerAdapter getAdapter() { return spinner.getAdapter(); } 
    public int getCount() { return spinner.getCount(); }    
    public Object getItemAtPosition(int position) { return spinner.getItemAtPosition(position); }   
    public long getItemIdAtPosition(int position) { return spinner.getItemIdAtPosition(position); }
    public Object getSelectedItem() { return spinner.getSelectedItem(); }
    public long getSelectedItemId() { return spinner.getSelectedItemId(); }
    public int getSelectedItemPosition() { return spinner.getSelectedItemPosition(); }
    public void setEnabled(boolean enabled) { spinner.setEnabled(enabled); }
    public boolean isEnabled() { return spinner.isEnabled(); }
}

我创建了一个小工具方法来改变Spinner选择而不通知用户:

private void setSpinnerSelectionWithoutCallingListener(final Spinner spinner, final int selection) {
    final OnItemSelectedListener l = spinner.getOnItemSelectedListener();
    spinner.setOnItemSelectedListener(null);
    spinner.post(new Runnable() {
        @Override
        public void run() {
            spinner.setSelection(selection);
            spinner.post(new Runnable() {
                @Override
                public void run() {
                    spinner.setOnItemSelectedListener(l);
                }
            });
        }
    });
}

它禁用侦听器，更改选择，然后重新启用侦听器。

诀窍是调用对UI线程是异步的，所以必须在连续的处理程序中执行。

这也不是一个优雅的解决方案。事实上，这有点像鲁布-戈德堡，但似乎很有效。通过扩展数组适配器并覆盖其getDropDownView，我确保旋转器至少被使用过一次。在新的getDropDownView方法中，我有一个布尔标志，被设置为显示下拉菜单至少被使用过一次。在设置标志之前，我会忽略对侦听器的调用。

MainActivity.onCreate ():

ActionBar ab = getActionBar();
ab.setDisplayShowTitleEnabled(false);
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
ab.setListNavigationCallbacks(null, null);

ArrayList<String> abList = new ArrayList<String>();
abList.add("line 1");
...

ArAd  abAdapt = new ArAd (this
   , android.R.layout.simple_list_item_1
   , android.R.id.text1, abList);
ab.setListNavigationCallbacks(abAdapt, MainActivity.this);

覆盖的数组适配器:

private static boolean viewed = false;
private class ArAd extends ArrayAdapter<String> {
    private ArAd(Activity a
            , int layoutId, int resId, ArrayList<String> list) {
        super(a, layoutId, resId, list);
        viewed = false;
    }
    @Override
    public View getDropDownView(int position, View convertView,
            ViewGroup parent) {
        viewed = true;
        return super.getDropDownView(position, convertView, parent);
    }
}

修改监听器:

@Override
public boolean onNavigationItemSelected(
   int itemPosition, long itemId) {
   if (viewed) {
     ...
   }
   return false;
}
