Java 数据绑定时如何在androidxml中编写三元操作条件,java,android,android-databinding,Java,Android,Android Databinding,如何在使用数据绑定的同时在androidxml中编写三元操作的等价表达式 android:visibility="@{(assessmentquestionanswer.type.equals(@string/editText_type)? View.VISIBLE : View.GONE) || (assessmentquestionanswer.type.equals(@string/date)? View.VISIBLE : View.GONE)}" 目前，我收到一条错误消息 必须能

如何在使用数据绑定的同时在androidxml中编写三元操作的等价表达式

android:visibility="@{(assessmentquestionanswer.type.equals(@string/editText_type)?  View.VISIBLE : View.GONE) || (assessmentquestionanswer.type.equals(@string/date)?  View.VISIBLE : View.GONE)}"
目前，我收到一条错误消息 必须能够找到布尔值和int的公共父级

请尝试以下操作：

android:visibility="@{(assessmentquestionanswer.type.equals(@string/editText_type) || assessmentquestionanswer.type.equals(@string/date))?  View.VISIBLE : View.GONE}"
你的实施方式是错误的，你目前的状况是

(assessmentquestionanswer.type.equals(@string/editText_type)?  View.VISIBLE : View.GONE) || (assessmentquestionanswer.type.equals(@string/date)?  View.VISIBLE : View.GONE)
                          View.VISIBLE                                                   ||                            View.VISIBLE
这是不对的。应该是

android:visibility="@{(assessmentquestionanswer.type.equals(@string/editText_type) || assessmentquestionanswer.type.equals(@string/date)) ?  View.VISIBLE : View.GONE}"
android:visibility=“a | b”是否正常工作？
yourVisibleObject.setVisibility（yourVisibleObject.getVisibility（）！=View.VISIBLE？View.VISIBLE:View.INVISIBLE）使用java（非xml格式）
