view 状态动画
stateListAnimator
一、xml配置 方法
res/xml/animate_scale.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- the pressed state; increase x and y size to 150% --> <item android:state_pressed="true"> <set> <objectAnimator android:propertyName="scaleX" android:duration="@android:integer/config_shortAnimTime" android:valueTo="1.5" android:valueType="floatType"/> <objectAnimator android:propertyName="scaleY" android:duration="@android:integer/config_shortAnimTime" android:valueTo="1.5" android:valueType="floatType"/> </set> </item> <!-- the default, non-pressed state; set x and y size to 100% --> <item android:state_pressed="false"> <set> <objectAnimator android:propertyName="scaleX" android:duration="@android:integer/config_shortAnimTime" android:valueTo="1" android:valueType="floatType"/> <objectAnimator android:propertyName="scaleY" android:duration="@android:integer/config_shortAnimTime" android:valueTo="1" android:valueType="floatType"/> </set> </item> </selector>
调用方:
<Button android:stateListAnimator="@xml/animate_scale" ... />
二、java代码中调用
AnimatorInflater.loadStateListAnimator() View.setStateListAnimator()
AnimatedStateListDrawable
<!-- res/drawable/myanimstatedrawable.xml --> <animated-selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- provide a different drawable for each state--> <item android:id="@+id/pressed" android:drawable="@drawable/drawableP" android:state_pressed="true"/> <item android:id="@+id/focused" android:drawable="@drawable/drawableF" android:state_focused="true"/> <item android:id="@id/default" android:drawable="@drawable/drawableD"/> <!-- specify a transition --> <transition android:fromId="@+id/default" android:toId="@+id/pressed"> <animation-list> <item android:duration="15" android:drawable="@drawable/dt1"/> <item android:duration="15" android:drawable="@drawable/dt2"/> ... </animation-list> </transition> ... </animated-selector>
