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 > |

< application android:name = "com.skymobi.moposns.MyApplication" android:allowBackup = "true" android:icon = "@drawable/ic_launcher" android:label = "@string/app_name" android:theme = "@style/AppTheme" > < activity android:name = "com.skymobi.moposns.MainActivity" android:label = "@string/app_name" android:screenOrientation = "portrait" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > |
希望本文所述对大家Android程序设计有所帮助。
