在片段中的popupwindow中按下微调器时，应用程序崩溃 [英] app crashes when spinner is pressed inside popupwindow which is located in fragment

问题描述

我有一个带有按钮的片段.按下该按钮，如果输入的用户凭据与有效用户匹配(输入字段ara被选中以请求api)，则会显示一个弹出窗口，其中包含一个微调器，一个textview和一个editext.

i have a fragment with a button. The button is pressed and if the user credentials entered match a valid user(the input fields ara being checked requests to rest api) a popupwindow is displayed with a spinner, a textview and an editext.

称为

public void onResponse(String response) {
                    try {
                        JSONObject jsonObject = new JSONObject(response);
                        String success = jsonObject.getString(AppConfig.TAG_ERROR);
                        if (success.equals("true")){
                           errorresponseTtv.setText(jsonObject.getString(AppConfig.TAG_ERROR_MSG));
                        }
                        else{
                           errorresponseTtv.setText("Success!:\n User-> " + jsonObject.getString(AppConfig.TAG_USERNAME) + ", password-> " + jsonObject.getString(AppConfig.TAG_PASSWORD) + ", email-> " + jsonObject.getString(AppConfig.TAG_EMAIL));
                            inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                            View layout = inflater.inflate(R.layout.popup_login, null);

                            createPopUpWindow(layout);
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }

createPopUpWindow()

createPopUpWindow()

private void createPopUpWindow(final View layout) {
            popupWindow = new PopupWindow(layout,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    true);
            firmSpnr = (Spinner) layout.findViewById(R.id.firmSpnr);
            ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, arrayList);
            firmSpnr.setAdapter(arrayAdapter);
            popupWindow.setOutsideTouchable(true);
            popupWindow.setBackgroundDrawable(new ShapeDrawable());
            popupWindow.showAtLocation(layout, Gravity.CENTER, 0, 0);
            popupWindow.update();
}

将按预期显示popupWindow，但是当我按下微调器时会出现问题.

the popupWindow is displayed as it is expected but the problem occurs when i press the spinner.

日志消息为"Unable to add window -- token android.view.ViewRootImp"您的活动正在运行吗? 我搜索了其他人遇到的任何类似问题，并且发现必须推迟显示弹出窗口，直到调用所有生命周期方法为止.谁能提供解决此错误的解决方案?

The log message is "Unable to add window -- token android.view.ViewRootImp" is your activity running? i have searched about any similar issues others have faced and i found out that i must defer showing the popup until after all the lifecycle methods are called. Can anyone provide a solution on how to fix the error?

推荐答案

在Google https://code.google.com/p/android/issues/detail?id=202246

但是，在发布Android支持库之后，修订版 23.2.1 (2016年3月)此问题已解决.

But after release of Android Support Library, revision 23.2.1 (March 2016) This issue has been resolved.

修复了API级别21及以下与AppCompatSpinner的兼容性崩溃

将支持库更新为Android Support Library to 23.2.1
