最近遇到一個很奇怪的問題,兩個項目彈出的dialog背景顏色不一樣,一個是黑色的,一個是白色的,最后發現是AndroidManifest.xml文件里面application指定的android:theme設置的樣式不一樣。
黑色dialog背景效果圖:
dialog是黑色的時候application指定的樣式如下:
<!-- 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>
白色背景如圖:
dialog是白色背景的時候application指定的樣式如下:
<!-- 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>
總結:對比兩個樣式,我們很明顯的發現白色背景多繼承了一層,增加了AppBaseTheme樣式............希望我的總結能讓你們少遇到坑。。。
