Android Reveal动画开始活动 [英] Android Reveal Animation to start an Activity

问题描述

如何在两个活动之间使用显示动画"?关于如何使用它在Activity内部启动视图，有很多信息和示例，但是我想单击一个按钮并启动显示动画"以打开下一个Activity. 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"，然后在单击按钮时将其显示出来.但这行不通.我想知道是否可以将Reveal动画简单地定义为XML，但是我不知道该怎么做. 谢谢

how can I use Reveal Animation between two activities?? There's a lot of information and examples about how to use it to start a view inside an Activity, but I want to click a button and start a Reveal Animation to open the next Activity. I tried including the second layout inside the first one and setting it Invisible, and then reveal it when the button is clicked. But it doesn't work fine. I'm wondering if I can simply define the Reveal animation as an XML, but I wouldn't know how to. Thanks

推荐答案

Reveal Effect也成功地在活动和片段方面为我工作 应用以下代码来设置对活动或片段的显示效果.删除注释以使用代码下方的特定动画形式.

Reveal Effect successfully worked for me on activity and fragment too Apply below code to set reveal effect on activity or fragment. Remove Comment to use specific animation form below code.

->在setcontentview之后应用此代码

->Apply this code after setcontentview

                rootview = (RelativeLayout) findViewById(R.id.rootview);

->隐藏显示效果onBackPressed()

// previously visible view
            final View myView = findViewById(R.id.rootview);

            // get the center for the clipping circle
            int cx = myView.getWidth() / 2;
