Android主题和样式

1、位置
在Android的frameworks/base/core/res/res/values目录下有一下几个文件：
| 1 2 3 4 | themes.xml themes_device_defaults.xml styles.xml styles_device_defaults.xml |
分别定义了各种系统Theme，Style。
2、主题Theme
主要关注themes.xml,themes_device_defaults.xml两个文件。
themes.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），实际上就是在Holo主题上定制主题（For厂商）。
系统如何去选择默认的主题呢？
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | /**frameworks/base/core/java/android/content/res/Resources.java*/ /** @hide */ 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); } /** @hide */ 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，使用以前低版本主题;当>=11&&<14，使用Holo主题;>14的时候，使用DeviceDefault主题。
方便理解，下面把目前所有的版本号列出来，也顺便温习一下android的历史：
3、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。
除此之外，还有很多，在此一一列出，打字太痛苦了，我贴出截图：
了解android系统定义的主题之后，我们就可以根据实际情况在自己的应用中使用这些主题，但是如果想修改主题的某些内容，需要进一步深入。
4、详解每个主题中定义item分类
一个完整的主题应该定义哪些内容呢，以Theme为例，如下：
1）颜色
| 1 2 3 4 5 6 7 8 9 10 | <item name= "colorForeground" > @android :color/bright_foreground_dark</item> <item name= "colorForegroundInverse" > @android :color/bright_foreground_dark_inverse</item> <item name= "colorBackground" > @android :color/background_dark</item> <item name= "colorBackgroundCacheHint" >?android:attr/colorBackground</item> <item name= "colorPressedHighlight" > @color /legacy_pressed_highlight</item> <item name= "colorLongPressedHighlight" > @color /legacy_long_pressed_highlight</item> <item name= "colorFocusedHighlight" > @color /legacy_selected_highlight</item> <item name= "colorMultiSelectHighlight" > @color /legacy_selected_highlight</item> <item name= "colorActivatedHighlight" > @color /legacy_selected_highlight</item> |
2）字体
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | <!-- Text styles --> <item name= "textAppearance" > @android :style/TextAppearance</item> <item name= "textAppearanceInverse" > @android :style/TextAppearance.Inverse</item> <item name= "textColorPrimary" > @android :color/primary_text_dark</item> <item name= "textColorSecondary" > @android :color/secondary_text_dark</item> <item name= "textColorTertiary" > @android :color/tertiary_text_dark</item> <item name= "textColorPrimaryInverse" > @android :color/primary_text_light</item> <item name= "textColorSecondaryInverse" > @android :color/secondary_text_light</item> <item name= "textColorTertiaryInverse" > @android :color/tertiary_text_light</item> <item name= "textColorPrimaryDisableOnly" > @android :color/primary_text_dark_disable_only</item> <item name= "textColorPrimaryInverseDisableOnly" > @android :color/primary_text_light_disable_only</item> <item name= "textColorPrimaryNoDisable" > @android :color/primary_text_dark_nodisable</item> <item name= "textColorSecondaryNoDisable" > @android :color/secondary_text_dark_nodisable</item> <item name= "textColorPrimaryInverseNoDisable" > @android :color/primary_text_light_nodisable</item> <item name= "textColorSecondaryInverseNoDisable" > @android :color/secondary_text_light_nodisable</item> <item name= "textColorHint" > @android :color/hint_foreground_dark</item> <item name= "textColorHintInverse" > @android :color/hint_foreground_light</item> <item name= "textColorSearchUrl" > @android :color/search_url_text</item> <item name= "textColorHighlight" > @android :color/highlighted_text_dark</item> <item name= "textColorHighlightInverse" > @android :color/highlighted_text_light</item> <item name= "textColorLink" > @android :color/link_text_dark</item> <item name= "textColorLinkInverse" > @android :color/link_text_light</item> <item name= "textColorAlertDialogListItem" > @android :color/primary_text_light_disable_only</item> <item name= "textAppearanceLarge" > @android :style/TextAppearance.Large</item> <item name= "textAppearanceMedium" > @android :style/TextAppearance.Medium</item> <item name= "textAppearanceSmall" > @android :style/TextAppearance.Small</item> <item name= "textAppearanceLargeInverse" > @android :style/TextAppearance.Large.Inverse</item> <item name= "textAppearanceMediumInverse" > @android :style/TextAppearance.Medium.Inverse</item> <item name= "textAppearanceSmallInverse" > @android :style/TextAppearance.Small.Inverse</item> <item name= "textAppearanceSearchResultTitle" > @android :style/TextAppearance.SearchResult.Title</item> <item name= "textAppearanceSearchResultSubtitle" > @android :style/TextAppearance.SearchResult.Subtitle</item> <item name= "textAppearanceEasyCorrectSuggestion" > @android :style/TextAppearance.EasyCorrectSuggestion</item> <item name= "textAppearanceMisspelledSuggestion" > @android :style/TextAppearance.MisspelledSuggestion</item> <item name= "textAppearanceAutoCorrectionSuggestion" > @android :style/TextAppearance.AutoCorrectionSuggestion</item> <item name= "textAppearanceButton" > @android :style/TextAppearance.Widget.Button</item> <item name= "editTextColor" > @android :color/primary_text_light</item> <item name= "editTextBackground" > @android :drawable/edit_text</item> <item name= "candidatesTextStyleSpans" > @android :string/candidates_style</item> <item name= "textCheckMark" > @android :drawable/indicator_check_mark_dark</item> <item name= "textCheckMarkInverse" > @android :drawable/indicator_check_mark_light</item> <item name= "textAppearanceLargePopupMenu" > @android :style/TextAppearance.Widget.PopupMenu.Large</item> <item name= "textAppearanceSmallPopupMenu" > @android :style/TextAppearance.Widget.PopupMenu.Small</item> |
