问题 I want to use Material Theme in my application which has minimum sdk version of 8. As per docs - "The material theme is only available in Android 5.0 (API level 21) and above. The v7 Support Libraries provide themes with material design styles for some widgets and support for customizing the color palette." Does it mean I can use it if I add v7 Support Libarary in my project? Because after adding this library I got the following error: android:Theme.Material.Light requires API level 21

问题 You can set the theme for your app, but I'm wondering if it's possible to find out which one is used by the device. Currently, my app uses Theme.AppCompat.Light . I'd like to avoid changing the theme. P.S. I've already tried to set it to Theme.DeviceDefault and access its ID using reflection, but no luck so far. try { setTheme(android.R.style.Theme_DeviceDefault); Class<Context> contextClass = Context.class; Method getThemeMethod = contextClass.getMethod("getThemeResId"); getThemeMethod

问题 After updating the appcompat library to the latest version (v21) to apply the material design, my custom theme isn't used anymore on Android 4.0.X devices unless I explicitly declare it in the XML. I have tested the theme on Android 2.3.X and 5.0.0 devices and it works on those devices. But it's not working on my HTC One S with Android 4.0.3. What do I need to do to fix this? My themes.xml <style name="Theme.Custom" parent="@style/Theme.AppCompat.Light"> <item name="android:editTextStyle">
