如何在android中使用constraintSet在一个constraintLayout中显示具有不同组件和ID的不同xml布局
我有一个片段，我需要展示，并通过一些步骤（在本例中，我有3个步骤）将一些XML布局融入其中，我知道我们可以简单地将布局包含到父片段布局中，只处理可见/消失的布局。但是我想用ConstraintLayout中的ConstraintSet来实现它。当我搜索将另一个XML布局加载到父XML布局时，每个XML布局中的两个根元素都必须是具有相同组件和相同ID的约束布局。但在我的示例中，我有不同的XML布局和根元素约束布局，但在每个XML布局中，我有不同的组件和ID。现在我的问题是如何根据步骤使用另一个XML布局更改部分XML布局？ 我们关心的是平滑这个布局和改变一些动画布局。这些是我的文件： 拾取碎片：如何在android中使用constraintSet在一个constraintLayout中显示具有不同组件和ID的不同xml布局,android,xml,android-constraintlayout,constraintset,Android,Xml,Android Constraintlayout,Constraintset,我有一个片段，我需要展示，并通过一些步骤（在本例中，我有3个步骤）将一些XML布局融入其中，我知道我们可以简单地将布局包含到父片段布局中，只处理可见/消失的布局。但是我想用ConstraintLayout中的ConstraintSet来实现它。当我搜索将另一个XML布局加载到父XML布局时，每个XML布局中的两个根元素都必须是具有相同组件和相同ID的约束布局。但在我的示例中，我有不同的XML布局和根元素约束布局，但在每个XML布局中，我有不同的组件和ID。现在我的问题是如何根据步骤使用另一个XM
