Android-Use the theme profile to get rid of the short black screen of the program launch screen

About the black screen

By default, when the program starts, there is a black screen period, because the first activity loads some data, such as initializing the list data.

Removal steps

1./res/values/styles.xml in Theme, add a Android:windowbackgrounds property to set the desired picture

2. In Androidmanifest.xml, set theme to the first startup activity.

3. Add/res/drawable-port/loading.png (if the splash screen of the horizontal screen, please put in/res/drawable-land/loading.png)

4. Complete

Code
