在我的应用程序我有一个自定义AlertDialog（使用的ShowDialog由系统处理（））​​，其中包含有2个选项卡的tabhost。在选项卡中的一个是一个微调。只要我能转动我的屏幕没有问题的微调是不开放（显示微调对话框）。如果在旋转过程中的微调是开放的，我得到这样的：

In my app I have a custom AlertDialog (handled by the system using showDialog()) which contains a tabhost with 2 tabs. In one of the tabs is a spinner. I can rotate my screen without problems as long as the spinner isn't open (spinner dialog displayed). If the spinner is open during rotation, I get this:

所以...

So...

1 - 是否可以在的onPause（）

1 - Is it possible to programmatically close the spinner during onPause()?

2 - 有没有我应该使用不同的方法

2 - Is there a different method I should be using?

3 - 如果没有妥善的解决办法，我怎么抓住这个特殊的例外？ （不好的做法，我知道，但轰然需要停止，并且因为活性被破坏后重建本身正确，就不会反正无所谓。

3 - If there isn't a proper solution, how do I catch this particular Exception? (Bad practice I know, but the crashing needs to be stopped, and since the activity reconstructs itself properly after being destroyed, it wouldn't matter anyway.

......也请为所有的爱情是神圣的，不建议我加入安卓configChanges =定向来我的活动宣言。我非常惊讶多久被接受为正式的修复，所有方向的问题。

... And please for the love of all that is holy, do not suggest that I add android:configChanges="orientation" to my activity declaration. It amazes me how often that is accepted as the official fix-all for orientation issues.

修改，了解更多信息

下面是我的对话创造code，以供参考：

Here is my dialog creation code for reference:

static final int ID_DIALOG_CHOOSER = 1;
int pref_location;
private Dialog dialog;

...

protected Dialog onCreateDialog(int id)
{
    switch(id)
    {
    case ID_DIALOG_CHOOSER:
        dialog = show(ID_DIALOG_CHOOSER);
        break;
    }
    return dialog;
}

...

showDialog(DialogView.ID_DIALOG_CHOOSER);

...

Dialog show(final int dialogType) 
{
    if (dialogType == ID_DIALOG_CHOOSER)
    {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);

        // inflate tabhost layout
        View tabHostLayout = (View) inflater.inflate(R.layout.tabhost_layout, null);
        FrameLayout tabContent = (FrameLayout) tabHostLayout.findViewById(android.R.id.tabcontent);

        // inflate tab content layouts and add to tabhost layout
        LinearLayout tab1 = (LinearLayout) inflater.inflate(R.layout.dialog_tab1, null);
        tabContent.addView(tab1);
        LinearLayout tab2 = (LinearLayout) inflater.inflate(R.layout.dialog_tab2, null);
        tabContent.addView(tab2);

        // tab setup
        TabHost tabHost = (TabHost) tabHostLayout.findViewById(R.id.TabHost_Dialog_Tabs);
        tabHost.setup();

        TabHost.TabSpec tab_1 = tabHost.newTabSpec("Category 1");
        tab_1.setContent(R.id.LinearLayout_Dialog_Tab1_Content);
        tab_1.setIndicator(this.getResources().getString(R.string.dialog_tab1), this.getResources().getDrawable(R.drawable.tabhost_icon_selector));
        tabHost.addTab(tab_1);

        TabHost.TabSpec tab_2 = tabHost.newTabSpec("Category 2");
        tab_2.setContent(R.id.LinearLayout_Dialog_Tab2_Content);
        tab_2.setIndicator(this.getResources().getString(R.string.dialog_tab2), this.getResources().getDrawable(R.drawable.tabhost_icon_selector));
        tabHost.addTab(tab_2);

        // spinner setup
        final Spinner spinner_location = (Spinner) tab1.findViewById(R.id.Spinner_Dialog_Location);
        String[] locationArrayVals = null;
        ArrayAdapter<CharSequence> adapter_location = null;
        locationArrayVals = this.getResources().getStringArray(R.array.location_array_vals);
        adapter_location = ArrayAdapter.createFromResource(this, R.array.location_array_listdisplay, android.R.layout.simple_spinner_item);
        adapter_location.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner_location.setAdapter(adapter_location);

        // ok button
        Button button_ok = (Button) tab1.findViewById(R.id.Button_Dialog_OK);
        button_ok.setOnClickListener(new View.OnClickListener() 
        {
            public void onClick(View view) 
            {
                pref_location = spinner_location.getSelectedItemPosition();
                dialog.dismiss();
            }
        });

        // create dialog
        builder.setTitle("Location")
        .setView(tabHost)
        .setCancelable(true);
        dialog = builder.create();
    }
    return dialog;
}

修改与临时解决方法

有关任何人感兴趣，我设法通过继承微调和覆盖 onDetachedFromWindow（）像这样至少停止崩溃：

For anybody interested I managed to at least stop the crashing by subclassing spinner and overriding onDetachedFromWindow() like so:

public static class CatchingSpinner extends Spinner
{
    public CatchingSpinner(Context context, AttributeSet attrs) 
    {
        super(context, attrs);
    }

    @Override
    protected void onDetachedFromWindow()
    {
        try
        {
            super.onDetachedFromWindow();
        }
        catch (IllegalArgumentException e)
        {
            // do whatever
        }
    } 
}

就像我说的，一个解决办法。还是努力寻找解决方案。 ：/

Like I said, a workaround. Still working on a solution. :/

推荐答案

我找到了一个更好的解决方案。这其实并不是那么难的一个按钮的外观和行为类似微调（除了崩溃，幸好）代替微调。

I found a better solution. It is actually not so hard to replace Spinner with a button that looks and behaves like Spinner (except the crash, fortunately).

<Button 
     android:background="@android:drawable/btn_dropdown" 
     android:gravity="left|center_vertical"
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" />

public void showSpinner() {
    AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
    builder.setTitle(_spinnerPrompt);
    builder.setSingleChoiceItems(_spinnerOptions, _spinnerSelection,
      new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
            _spinnerSelection = item;
            _pseudoSpinner.setText(_spinnerOptions[item]);
            _restoreSpinnerOnRestart = false;
            dialog.dismiss();
        }
    });
    builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialog) {
            _restoreSpinnerOnRestart = false;
        }
    });
    AlertDialog alert = builder.create();
    _restoreSpinnerOnRestart = true;
    alert.show();
    }

@Override
public Bundle onSaveInstanceState() {
    Bundle state = super.onSaveInstanceState();
    state.putBoolean(STATE_SPINNER_RESTORE, _restoreSpinnerOnRestart);
    state.putInt(STATE_SPINNER_SELECTION, _spinnerSelection);
    return state;
};

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    _spinnerSelection = savedInstanceState.getInt(STATE_SPINNER_SELECTION, -1);
    _restoreSpinnerOnRestart = savedInstanceState.getBoolean(STATE_SPINNER_RESTORE);
    _pseudoSpinner.setText(_spinnerOptions[_spinnerSelection]);

    if (_restoreSpinnerOnRestart) {
        showSpinner();
    }
};
