在遇到同样的问题后，我想出了这个使用标签的解决方案。 它背后的思想很简单:无论何时以编程方式更改旋转器，都要确保标记反映所选的位置。然后在侦听器中检查所选位置是否等于标记。如果是，则以编程方式更改了旋转器选择。

下面是我的新“spinner proxy”类:

package com.samplepackage;

import com.samplepackage.R;
import android.widget.Spinner;

public class SpinnerFixed {

    private Spinner mSpinner;

    public SpinnerFixed(View spinner) {
         mSpinner = (Spinner)spinner;
         mSpinner.setTag(R.id.spinner_pos, -2);
    }

    public boolean isUiTriggered() {
         int tag = ((Integer)mSpinner.getTag(R.id.spinner_pos)).intValue();
         int pos = mSpinner.getSelectedItemPosition();
         mSpinner.setTag(R.id.spinner_pos, pos);
         return (tag != -2 && tag != pos);
    }

    public void setSelection(int position) {
        mSpinner.setTag(R.id.spinner_pos, position);
        mSpinner.setSelection(position);
    }

    public void setSelection(int position, boolean animate) {
        mSpinner.setTag(R.id.spinner_pos, position);
        mSpinner.setSelection(position, animate);
    }

    // If you need to proxy more methods, use "Generate Delegate Methods"
    // from the context menu in Eclipse.
}

在Values目录中还需要一个带有标记设置的XML文件。 我将我的文件命名为spinner_tag.xml，但这取决于您。 它是这样的:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
  <item name="spinner_pos" type="id" />
</resources>

现在取代

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

在你的代码中

SpinnerFixed myspinner;
...
myspinner = new SpinnerFixed(findViewById(R.id.myspinner));

让你的处理器看起来像这样:

myspinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        if (myspinner.isUiTriggered()) {
            // Code you want to execute only on UI selects of the spinner
        }
    }

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

函数isUiTriggered()当且仅当旋转器已被用户更改时将返回true。注意，这个函数有一个副作用——它会设置标记，所以同一个监听器调用中的第二个调用总是返回false。

这个包装器还将处理在布局创建期间调用侦听器的问题。

玩得开心, 延斯。

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;
}

参考Dan Dyer的回答，尝试在post(Runnable)方法中注册OnSelectListener:

spinner.post(new Runnable() {
    public void run() {
        spinner.setOnItemSelectedListener(listener);
    }
});

通过这样做，我所希望的行为终于发生了。

在本例中，它还意味着侦听器仅在更改的项上触发。

我用最简单的方法做到了:

private AdapterView.OnItemSelectedListener listener;
private Spinner spinner;

onCreate ();

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

listener = new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {

            Log.i("H - Spinner selected position", position);
        }

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

        }
    };

 spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
            spinner.setOnItemSelectedListener(listener);
        }

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

        }
    });

Done

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
