Android显示动画以开始活动
如何在两个活动之间使用显示动画？？有很多关于如何使用它在活动内启动视图的信息和示例，但是我想单击一个按钮并启动一个显示动画以打开下一个活动。 我尝试将第二个布局包含在第一个布局中，并将其设置为不可见，然后在单击按钮时显示它。但是它不好用。我想知道是否可以简单地将显示动画定义为XML，但我不知道如何定义。Android显示动画以开始活动,android,android-animation,Android,Android Animation,如何在两个活动之间使用显示动画？？有很多关于如何使用它在活动内启动视图的信息和示例，但是我想单击一个按钮并启动一个显示动画以打开下一个活动。 我尝试将第二个布局包含在第一个布局中，并将其设置为不可见，然后在单击按钮时显示它。但是它不好用。我想知道是否可以简单地将显示动画定义为XML，但我不知道如何定义。 谢谢例如，您可以为活动的父级布局设置动画。这里有一个可能对你有帮助的答案。它会在活动中淡出，但如果您了解它是如何完成的，则可以应用任何动画 要取消标准内置活动动画，可以使用以下方法： 当你们开
谢谢例如，您可以为活动的父级布局设置动画。这里有一个可能对你有帮助的答案。它会在活动中淡出，但如果您了解它是如何完成的，则可以应用任何动画 要取消标准内置活动动画，可以使用以下方法：
当你们开始你们的活动时。展示效果在活动和片段上也成功地对我起作用 应用下面的代码设置对活动或片段的显示效果。删除注释以使用代码下面的特定动画形式 ->在setcontentview之后应用此代码

onBackPressed（）谢谢，这正是我想要的。非常感谢你。最后我找到了一些解决办法。您能告诉我如何找到右上角的Cx，Cy值吗。
