我找到了更优雅的解决方法。它包括计算ArrayAdapter(在您的例子中是“适配器”)被调用的次数。假设你有一个转轮，你调用:

int iCountAdapterCalls = 0;

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.pm_list, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

在onCreate之后声明一个int计数器，然后在onItemSelected()方法内部放置一个“if”条件来检查atapter被调用了多少次。在你的例子中，你只调用了一次:

if(iCountAdapterCalls < 1)
{
  iCountAdapterCalls++;
  //This section executes in onCreate, during the initialization
}
else
{
  //This section corresponds to user clicks, after the initialization
}

设计一种通用的转轮，只需数据输入，由用户选择，优点: 1. 保持旋转样式相同的应用程序。 2. 在任何地方启动旋转器。 3.易于处理链接转轮(重新启动ReuseSpinner与不同的数据)。

我的演示示例:ReuseSpinner 传递数据到ReuseSpinner:

Intent intent = new Intent(MainActivity.this, SpinnerActivity.class);
intent.putExtra(SpinnerActivity.Extra_Resource, arrayList);
startActivityForResult(intent, mRequestCode_select_country_prompt);

获取用户选择:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == mRequestCode_select_country && resultCode == RESULT_OK){
            if(data != null){
                Map.Entry<String,String> entry = (Map.Entry<String,String>) data.getSerializableExtra(SpinnerActivity.Result_Data);
                if(entry != null){
                    Log.i(TAG, String.format("get result -> key:%s , value:%s", entry.getKey(), entry.getValue()));

                }
            }
        }
    }

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
}

布尔标志或计数器的解决方案没有帮助我，因为在方向变化onItemSelected()调用“飞越”标志或计数器。

我子类化了android.widget.Spinner，并做了一些小的补充。相关部分如下。这个解决方案对我很有效。

private void setHandleOnItemSelected()
{
  final StackTraceElement [] elements = Thread.currentThread().getStackTrace();

  for (int index = 1; index < elements.length; index++)
  {
     handleOnItemSelected = elements[index].toString().indexOf("PerformClick") != -1; //$NON-NLS-1$

     if (handleOnItemSelected)
     {
        break;
     }
  }
}

@Override
public void setSelection(int position, boolean animate)
{
  super.setSelection(position, animate);

  setHandleOnItemSelected();
}

@Override
public void setSelection(int position)
{
  super.setSelection(position);

  setHandleOnItemSelected();
}

public boolean shouldHandleOnItemSelected()
{
  return handleOnItemSelected;
}

我得到了一个非常简单的答案，百分百确定它有效:

boolean Touched=false; // this a a global variable

public void changetouchvalue()
{
   Touched=true;
}

// this code is written just before onItemSelectedListener

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

//inside your spinner.SetonItemSelectedListener , you have a function named OnItemSelected iside that function write the following code

if(Touched)
{
 // the code u want to do in touch event
}

spinner.setSelection(Adapter.NO_SELECTION, false);
