1. reference：参考某一资源ID。（1）属性定义：<declare-styleable name = "名称"><attr name = "background" format = "reference" /></declare-styleable>（2）属性使用：<ImageViewandroid:layout_width = "42dip"android:layout_height = "42dip"android:background = "@drawable/图片ID"/>2. color：颜色值。（1）属性定义：<declare-styleable name = "名称"><attr name = "textColor" format = "color" /></declare-styleable>（2）属性使用：<TextViewandroid:layout_width = "42dip"android:layout_height = "42dip"android:textColor = "#00FF00"/>3. boolean：布尔值。（1）属性定义：<declare-styleable name = "名称"><attr name = "focusable" format = "boolean" /></declare-styleable>（2）属性使用：<Buttonandroid:layout_width = "42dip"android:layout_height = "42dip"android:focusable = "true"/>4. dimension：尺寸值。（1）属性定义：<declare-styleable name = "名称"><attr name = "layout_width" format = "dimension" /></declare-styleable>（2）属性使用：<Buttonandroid:layout_width = "42dip"android:layout_height = "42dip"/>5. float：浮点值。（1）属性定义：<declare-styleable name = "AlphaAnimation"><attr name = "fromAlpha" format = "float" /><attr name = "toAlpha" format = "float" /></declare-styleable>（2）属性使用：<alphaandroid:fromAlpha = "1.0"android:toAlpha = "0.7"/>6. integer：整型值。（1）属性定义：<declare-styleable name = "AnimatedRotateDrawable"><attr name = "visible" /><attr name = "frameDuration" format="integer" /><attr name = "framesCount" format="integer" /><attr name = "pivotX" /><attr name = "pivotY" /><attr name = "drawable" /></declare-styleable>（2）属性使用：<animated-rotatexmlns:android = "http://schemas.android.com/apk/res/android" android:drawable = "@drawable/图片ID" android:pivotX = "50%" android:pivotY = "50%" android:framesCount = "12" android:frameDuration = "100"/>7. string：字符串。（1）属性定义：<declare-styleable name = "MapView"><attr name = "apiKey" format = "string" /></declare-styleable>（2）属性使用：<com.google.android.maps.MapViewandroid:layout_width = "fill_parent"android:layout_height = "fill_parent"android:apiKey = "0jOkQ80oD1JL9C6HAja99uGXCRiS2CGjKO_bc_g"/>8. fraction：百分数。（1）属性定义：<declare-styleable name="RotateDrawable"><attr name = "visible" /><attr name = "fromDegrees" format = "float" /><attr name = "toDegrees" format = "float" /><attr name = "pivotX" format = "fraction" /><attr name = "pivotY" format = "fraction" /><attr name = "drawable" /></declare-styleable>（2）属性使用：<rotatexmlns:android = "http://schemas.android.com/apk/res/android" android:interpolator = "@anim/动画ID"android:fromDegrees = "0" android:toDegrees = "360"android:pivotX = "200%"android:pivotY = "300%" android:duration = "5000"android:repeatMode = "restart"android:repeatCount = "infinite"/>9. enum：枚举值。（1）属性定义：<declare-styleable name="名称"><attr name="orientation"><enum name="horizontal" value="0" /><enum name="vertical" value="1" /></attr> </declare-styleable>（2）属性使用：<LinearLayoutxmlns:android = "http://schemas.android.com/apk/res/android"android:orientation = "vertical"android:layout_width = "fill_parent"android:layout_height = "fill_parent"></LinearLayout>10. flag：位或运算。（1）属性定义：<declare-styleable name="名称"><attr name="windowSoftInputMode"><flag name = "stateUnspecified" value = "0" /><flag name = "stateUnchanged" value = "1" /><flag name = "stateHidden" value = "2" /><flag name = "stateAlwaysHidden" value = "3" /><flag name = "stateVisible" value = "4" /><flag name = "stateAlwaysVisible" value = "5" /><flag name = "adjustUnspecified" value = "0x00" /><flag name = "adjustResize" value = "0x10" /><flag name = "adjustPan" value = "0x20" /><flag name = "adjustNothing" value = "0x30" /></attr> </declare-styleable>（2）属性使用：<activityandroid:name = ".StyleAndThemeActivity"android:label = "@string/app_name"android:windowSoftInputMode = "stateUnspecified | stateUnchanged | stateHidden"><intent-filter><action android:name = "android.intent.action.MAIN" /><category android:name = "android.intent.category.LAUNCHER" /></intent-filter></activity>注意：属性定义时可以指定多种类型值。（1）属性定义：<declare-styleable name = "名称"><attr name = "background" format = "reference|color" /></declare-styleable>（2）属性使用：<ImageViewandroid:layout_width = "42dip"android:layout_height = "42dip"android:background = "@drawable/图片ID|#00FF00"/>这篇关于Android之自定义属性，format详解的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
