位置

在Android Frameworks/base/core/res/res/values目录下

  • themes.xml
  • themes_device_defaults.xml
  • styles.xml
  • styles_device_defaults.xml

主题Theme

theme.xml定义了Android低版本的theme和Holo theme，themes_device_defaults.xml定义了DeviceDefault主题(继承自Holo主题)
系统如何选择默认主题呢？

/**frameworks/base/core/java/android/content/res/Resources.java*/
public static int selectDefaultTheme(int curTheme, int targetSdkVersion) {
    return selectSystemTheme(curTheme, targetSdkVersion,
            com.android.internal.R.style.Theme,
            com.android.internal.R.style.Theme_Holo,
            com.android.internal.R.style.Theme_DeviceDefault);
}    

public static int selectSystemTheme(int curTheme, int targetSdkVersion,
        int orig, int holo, int deviceDefault) {
    if (curTheme != 0) { 
        return curTheme;
    }    
    if (targetSdkVersion < Build.VERSION_CODES.HONEYCOMB) {
        // < 11
        return orig;
    }    
    if (targetSdkVersion < Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
         // < 14
         return holo;
    }    
    return deviceDefault;
}

当<11时使用低版本主题，>=11&&<14时使用Holo主题，>14时，使用DeviceDefault主题

系统主题Theme列表

系统默认大的主题是三种：Theme,Theme.Holo,Theme.DeviceDefault, 但是实际上在此基础系统还定义了大量的派生主题，最典型的是对应的Light主题。
