Question

我有一个传递给它的包的片段。捆绑包通过（使用Log标签验证）和代码中的textView更新（我知道这是因为我应该更新TextView之后的I Log getText）。我的问题是视觉表现（屏幕）没有显示更新。

            numberView = (TextView) getActivity().findViewById(R.id.textView20);

            //From CantactLog()
            Bundle arguments = getArguments();
            if ( arguments!= null) {
                sName = getArguments().getString("sName");
                sNumber = getArguments().getString("sNumber");

                if (sNumber != null){
                    PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
                    String formatedNumber = null;
                    try {
                        Phonenumber.PhoneNumber numberProto = phoneUtil.parse(sNumber, "US");
                        //Since you know the country you can format it as follows:
                        formatedNumber = phoneUtil.format(numberProto, PhoneNumberUtil.PhoneNumberFormat.NATIONAL);

                    } catch (NumberParseException e) {
                        System.err.println("NumberParseException was thrown: " + e.toString());
                    }
                    Log.i(TAG, " Formated Number " + formatedNumber);
                    sNumber= formatedNumber;

                    numberView.setText(sNumber);
                    // mPhoneSearch.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
                    scallName = sName;
                    Log.i(TAG, "sNumber = "+sNumber);
                    Log.i(TAG,"get text =" + numberView.getText().toString());

                }

            }

退出：

I / GifHeaderParser：Formated Number（650）555-1212

I / GifHeaderParser：sNumber =（650）555-1212

I / GifHeaderParser：get text =（650）555-1212

所以我回答了我自己的问题，当我调用片段打开时，我在片段传输中使用.add而不是.replace。
