本文实例讲述了Android编程中activity启动时出现白屏、黑屏问题的解决方法。分享给大家供大家参考,具体如下:
默认情况下 activity 启动的时候先把屏幕刷成白色,再绘制界面,绘制界面或多或少有点延迟,这段时间中你看到的就是白屏,显然影响用户体验,怎么消除呢?
在 Activity theme 设置style 即可

< style name = "AppTheme" parent = "android:Theme.Light.NoTitleBar" >
< item name = "android:windowIsTranslucent" >true</ item >
< item name = "android:windowNoTitle" >true</ item >
< item name = "android:windowActionBar" >false</ item >
< item name = "android:windowBackground" >@android:color/transparent</ item >
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</ style >
