问题描述
我想在屏幕上显示两个视图。一个是一个随机定位点的位图。我可以得到做显示器的setContentView（...）。
我也有两个位图，并且通过XML布局语言安排一个TextView，然后使用的setContentView（R.layout.activity_title）;
I want to display two views on a screen. One is a randomly positioned dot bitmaps. I can get that do display with setContentView(...). I also have two bitmaps and a textview that are arranged via xml layout language and then using setContentView(R.layout.activity_title);

推荐答案
在 XML 文件，同时声明查看在的FrameLayout ，一个应该是在对方之上，应最后声明。
Inside the XML file, declare both Views inside a FrameLayout, the one that should be in top of the other, should be declared last.
要声明一个自定义创建的视图，请使用以下格式：
To declare a custom created view, use the following format:
<com.mypackage.MyCustomView
android:layout_width=......
