2013.12.04 （7）——— android SlidingMenu之CustomAnimation
这个有3个例子，主要是介绍侧边栏显示时候的动画
public class CustomScaleAnimation extends CustomAnimation {public CustomScaleAnimation() {super(R.string.anim_scale, new CanvasTransformer() {@Overridepublic void transformCanvas(Canvas canvas, float percentOpen) {canvas.scale(percentOpen, 1, 0, 0);}});}}package com.jeremyfeinstein.slidingmenu.example.anim;import android.graphics.Canvas;import android.view.animation.Interpolator;import com.jeremyfeinstein.slidingmenu.example.R;import com.jeremyfeinstein.slidingmenu.example.R.string;import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu.CanvasTransformer;public class CustomSlideAnimation extends CustomAnimation {private static Interpolator interp = new Interpolator() {@Overridepublic float getInterpolation(float t) {t -= 1.0f;return t * t * t + 1.0f;}};public CustomSlideAnimation() {// see the class CustomAnimation for how to attach // the CanvasTransformer to the SlidingMenusuper(R.string.anim_slide, new CanvasTransformer() {@Overridepublic void transformCanvas(Canvas canvas, float percentOpen) {System.out.println(canvas.getHeight()*(1-interp.getInterpolation(percentOpen)));canvas.translate(0, canvas.getHeight()*(1-interp.getInterpolation(percentOpen)));}});}}package com.jeremyfeinstein.slidingmenu.example.anim;import android.graphics.Canvas;import com.jeremyfeinstein.slidingmenu.example.R;import com.jeremyfeinstein.slidingmenu.example.R.string;import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu.CanvasTransformer;public class CustomZoomAnimation extends CustomAnimation {public CustomZoomAnimation() {// see the class CustomAnimation for how to attach // the CanvasTransformer to the SlidingMenusuper(R.string.anim_zoom, new CanvasTransformer() {@Overridepublic void transformCanvas(Canvas canvas, float percentOpen) {float scale = (float) (percentOpen*0.25 + 0.75);canvas.scale(scale, scale, canvas.getWidth()/2, canvas.getHeight()/2);}});}}sm.setBehindCanvasTransformer(mTransformer);
