This article illustrates the solution to the problem of black screen when the Android program starts up. Share to everyone for your reference, specific as follows:

About black screen:

By default, when a program starts, it has a black screen period, because the first activity loads some data, such as initializing the list data, sending requests to the server, getting the data, and so on.

Removal method:

1. Add a style inside the style:

<style name= "Contentoverlay" parent= "@android: Style/theme.light" >
<itemname= "Android:windownotitle" >true</item>
<itemname= "android:windowistranslucent" >true</item>
<itemname= " Android:windowcontentoverlay "> @null </item>
</style>

2, set the theme to start the activity of the subject inside

<application
android:icon= "@drawable/icon"
android:label= "@string/app_name" Android:name= "
. Tweiboapplication "
android:debuggable=" true "
android:theme=" @style/contentoverlay ">
< Activity
android:name= ". Mainsplashactivity "
android:configchanges=" keyboardhidden|orientation "
android:theme=" @style Contentoverlay ">
<intent-filter> 
<actionandroid:name=" Android.intent.action.MAIN "/> 
<categoryandroid:name= "Android.intent.category.LAUNCHER"/> 
</intent-filter>
</ Activity>

Android Interface Switch black screen processing:

A black screen appears in the process of switching from A to B, and you can change the theme of B in the manifest file and add in theme:

<item name= "Android:windowistranslucent" >true</item>

So from A to B process, because B is transparent, so the background is a. Such a user experience is better.
