我有三个布局文件。一个名为activity_home，另一个名为activity_main，最后一个名为activity_test。 activity_main只是一个简单的布局，只有一个textview和一个按钮。 activity_test是一个包含文本视图的布局文件hello world.activity_home就像下面这样。如何在线性布局内开始新的活动？

我想开我的activity_home和我activity_test加载到名为“content_frame”里面activity_home当我在我的主要活动点击按钮的线性布局。我怎么做那件事？我的home.java文件的代码也在下面。

drawerLayout.setScrimColor(Color.TRANSPARENT);

linearLayout.setOnClickListener(this);
setActionBar();
createMenuList();
viewAnimator = new ViewAnimator<>(this, list, contentFragment, drawerLayout, this);

您不能加载一个活动中的另一个，但你可以加载一个“片段” ......如果你要共享显示内容，使该共享元素融入您在包括“片段”这两个活动。 –
