android:theme决定AlertDialog的背景颜色
最近遇到一个很奇怪的问题,两个项目弹出的dialog背景颜色不一样,一个是黑色的,一个是白色的,最后发现是AndroidManifest.xml文件里面application指定的android:theme设置的样式不一样。
黑色dialog背景效果图:
dialog是黑色的时候application指定的样式如下:
<!-- Application theme. --> <style name="AppTheme" parent="android:Theme.Light"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <item name="android:windowNoTitle">true</item> </style>
白色背景如图:
dialog是白色背景的时候application指定的样式如下:
<!-- Base application theme, dependent on API level. This theme is replaced by AppBaseTheme from res/values-vXX/styles.xml on newer devices. --> <style name="AppBaseTheme" parent="android:Theme.Light"> <!-- Theme customizations available in newer API levels can go in res/values-vXX/styles.xml, while customizations related to backward-compatibility can go here. --> </style> <!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <item name="android:windowNoTitle">true</item> </style>
总结:对比两个样式,我们很明显的发现白色背景多继承了一层,增加了AppBaseTheme样式............希望我的总结能让你们少遇到坑。。。
