我的问题是，我想使用activity_main布局并仍然拥有animatedView，我该怎么办？请不要说我的问题是我设置了setContentView的两倍，我知道我知道了！那是因为我想要一个球和一个布局。

其他人遇到我的问题：http://stackoverflow.com/questions/22580336/android-animatedview-taking-up-whole-activity-screen .

animatedView为自己创建一个空布局，如果我要删除"setContentView(animatedView)"我会有布局而不是我的球。

现在我有一个带球的空布局。

您能否发布activity_main的XML？

听起来您想要做的是将FrameLayout创建为活动布局中的顶级视图。这将允许您将子视图堆叠在一起。然后，在致电setContentView(R.layout.activity_main)后，您可以执行以下操作：

FrameLayout myRootLayout = (FrameLayout) findViewById(R.id.id_of_top_level_framelayout);
animatedView = new AnimatedView(this);
myRootLayout.addView(animatedView);

如果您想指定animatedView的z顺序，也可以使用addView(animatedView, index)。

请澄清我是否误解了你的问题。

将animatedView添加到现有布局
