My background color is not changing from white in the emulator. It shows in the design, but not the emulator.

Can anyone help?

tools:background="#66bb6a" should be android:background="#66bb6a" Using tools: will only only show it in Andoird Studio's preview, which is useful if you want to add mock content while you design, but not set it as default content in the app.
