問題：
小弟寫了一個ListView，ListView的item中有一個是TextView。當我點擊TextView的時候，會彈出一個PopupWindow。PopupWindow中是一個ListView。

當點擊PopupWindow中的ListView的時候，需要把 PopupWindow中的ListView的值傳給TextView。問題是，我debug，看見了TextView的值明明改變了，但是在頁面中的TextView的值卻沒有改變

代碼：

public class OperatorLogItem extends BaseAdapter {


    private Context mcontext;
    private LayoutInflater mInflater;
    private TextView tv_operator_mark;
    private PopupWindow pw_operator_mark;   // 彈框
    private List<String> mOperatorMarkList = new ArrayList<>(); //彈出的窗體的數(shù)據(jù)
    private AddItemListView mAddItemListView;
    private  AddItemListViewAdapter mAddItemListViewAdapter;

    Spinner mSpOperatorMark ,mSpOperatorRecord,mSpOperatorSignature;

    EditText etOperatorAllTime, etOperatorBeginTime, etOperatorOverTime,etOperatorRemark;

    public OperatorLogItem(Context context) {
        super();
        this.mcontext = context;
        this.mInflater = LayoutInflater.from(mcontext);
        // 因為多個OperatorLogItem 共用一個 ListView,所以只初始化一次。
        initTvClickPopupWindowData(mOperatorMarkList);
        mAddItemListView = new AddItemListView(mcontext);
        mAddItemListViewAdapter = new AddItemListViewAdapter(mcontext,mOperatorMarkList);

    }

            for (String s : arrays) {
                list.add(s);
            }
        }
    }

    //初始化點擊TextView 彈出窗體
    private void initTvClickPopupWindow(TextView tv) {
        //初始化窗體
        tv.post(new Runnable() {
            @Override
            public void run() {
                pw_operator_mark = new PopupWindow(mAddItemListView, RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT,true);
                pw_operator_mark.setTouchable(true);
                pw_operator_mark.setOutsideTouchable(true);
                // 這句話是必須寫的，雖然不知道為什么??！
                pw_operator_mark.setBackgroundDrawable(new BitmapDrawable(mcontext.getResources(), (Bitmap) null));
            }
        });
        // 點擊彈出窗體
        tv.setOnClickListener(new View.OnClickListener() {
            @Override

                pw_operator_mark.showAsDropDown(v);
            }
        });
    }

PopupWindow中ListView的適配器
