Question

我正在使用Android本机sip堆栈创建一个简单的sipcall。我希望在成功的SIP连接上显示一个特定的浮动操作按钮，并在失败的SIP连接上隐藏相同的浮动操作按钮。默认情况下，显示浮动操作按钮。有些显示部分不起作用，为什么找不到任何解决方案。正在android版本27上工作。以下是sip配置文件的实现部分。

                        /**
                         * Name: onRegistrationDone
                         * Description: Logs a status message indicating the
                         *              SipProfile successfully registered.
                         */
                        public void onRegistrationDone(String localProfileUri, long expiryTime) {



                            Log.e("$$", "Sip Profile <" + localProfileUri + "> successfully registered");
                            System.out.println( " login successful");

///我在成功注册时显示浮动操作按钮-无效

                        FloatingActionButton fab3 = (FloatingActionButton) findViewById(R.id.fab3);
                        fab3.show();
                        }

                        /**
                         * Name: onRegistrationFailed
                         * Description: Logs a status message indicating the
                         *              SipProfile failed to register.
                         */
                        public void onRegistrationFailed(String localProfileUri, int errorCode, String errorMessage) {

//隐藏浮动操作按钮-起作用

                            FloatingActionButton fab3 = (FloatingActionButton) findViewById(R.id.fab3);

                            fab3.hide();


                            Log.e("$$", "Sip Profile failed to register <" + localProfileUri + "> " +
                                    " Error message: " + errorMessage);
                            System.out.println( " login unsuccessful. Error message:" + errorMessage);
                        }
                    });
        } catch (ParseException e) {
            Log.e("$$", "SipProfile was not built.");
            e.printStackTrace();
        } catch (SipException e) {
            e.printStackTrace();
        }
    }
}

请尝试此操作，可能会有所帮助：

runOnUiThread(new Runnable() {
            @Override
            public void run() {
                fab3.show();
            }
        });

浮动动作按钮不显示show（）吗？
