Java 如何在设备方向更改期间在上下文操作栏中保持高亮显示的ListView项及其状态

我实现了一个listview，其选择模式设置为choice\u mode\u MULTIPLE\u mode。下面是一些代码：

listView.setMultiChoiceModeListener(new MultiChoiceModeListener() {

            private int check = 0;

            @Override
            public boolean onPrepareActionMode(ActionMode arg0, Menu arg1) {
                // TODO Auto-generated method stub
                return false;
            }

            @Override
            public void onDestroyActionMode(ActionMode arg0) {
                // TODO Auto-generated method stub
                adapter.clearSelection();
            }

            @Override
            public boolean onCreateActionMode(ActionMode arg0, Menu arg1) {
                // TODO Auto-generated method stub

                check = 0;

                MenuInflater inflater = getMenuInflater();
                inflater.inflate(R.menu.context_menu, arg1);
                return true;
            }

            @Override
            public boolean onActionItemClicked(final ActionMode arg0,
                    MenuItem arg1) {
                // TODO Auto-generated method stub
                if ((PinPad.mMediaPlayer != null)
                        && (!PinPad.mMediaPlayer.isPlaying())) {
                    switch (arg1.getItemId()) {
                    case R.id.item_delete:

                        LayoutInflater inflater = getLayoutInflater();
                        View dialogLayout = inflater.inflate(
                                R.layout.delete_confirmation, null);
                        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                                MainListActivity.this);
                        alertDialogBuilder.setView(dialogLayout);

                        final AlertDialog confirmationDialog = alertDialogBuilder
                                .create();
                        confirmationDialog.show();

                        Button buttonNo = (Button) dialogLayout
                                .findViewById(R.id.buttonNo);
                        Button buttonYes = (Button) dialogLayout
                                .findViewById(R.id.buttonYes);

                        buttonNo.setOnClickListener(new View.OnClickListener() {

                            @Override
                            public void onClick(View view) {
                                // TODO Auto-generated method stub
                                weGotTheTime.clear();
                                weGotTheType.clear();
                                weGotTheDays.clear();
                                weGotTheRings.clear();

                                weGotTheIDs.clear();

                                confirmationDialog.dismiss();

                                arg0.finish();
                            }
                        });

                        buttonYes

            @Override
            public void onItemCheckedStateChanged(ActionMode mode,
                    int position, long id, boolean checked) {
                // TODO Auto-generated method stub
                td = results.get(position).getDays();

                if (checked) {

        listView.setOnItemLongClickListener(new OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub
                listView.setItemChecked(arg2, !adapter.isPositionChecked(arg2));
                vibrator.vibrate(50);
                return false;
            }
        });

这非常有效，长时间单击listview项目会高亮显示它，效果很好。但是，一旦我将设备方向从纵向更改为横向，反之亦然，高亮显示消失，上下文操作栏仍在显示，但未显示任何选定内容。有什么帮助吗？我试过制作选择器和抽绳器，然后用手工的方式来做，但还是没有成功。我在这个问题上花了几个星期，我想知道是否有人知道如何解决它

谢谢。

看看您是否可以使用此帮助：

android:configChanges=方向|键盘隐藏

必须重新创建您的活动，您是否尝试使用onSaveInstanceState和onRestoreInstanceState保留信息？我有，它只保存了所做选择的数量。奇怪的是，当我调用listView.setItemCheckedposition时，为true；好像什么都没发生。我试过使用这种方法，但不幸的是，它不起作用。
