安卓摇一摇包含 objectAnimatorvalueAnimator的动画效果 _ValueAnimator

一万年来谁著史，三千里外欲封侯。这篇文章主要讲述安卓摇一摇包含 objectAnimatorvalueAnimator的动画效果相关的知识，希望能为你提供帮助。

onpause的时候也记得注销传感器呀

自定义view 利用ValueAnimator实现窗帘开闭合动画

public class CurtainView extends View implements ValueAnimator.AnimatorUpdateListener,Animation.AnimationListener { int mCurtainstate = 0; //0 完全打开 1 打开 2 闭合动作3 完全闭合private Paint mPaint; private RectF mRectF; private ValueAnimator mAnimator; public CurtainView(Context context) { this(context,null); }public CurtainView(Context context, @Nullable AttributeSet attrs) { this(context, attrs,0); }public CurtainView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); mPaint = new Paint(); mPaint.setColor(Color.WHITE); mAnimator = new ValueAnimator(); mAnimator.setDuration(500); mAnimator.addUpdateListener(this); mAnimator.setInterpolator(new DecelerateInterpolator()); }@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); setMeasuredDimension(Math.min(widthMeasureSpec,heightMeasureSpec),Math.min(widthMeasureSpec,heightMeasureSpec)); }@Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); if (mRectF==null){ mRectF = new RectF(0,0,getMeasuredWidth(),getMeasuredHeight()); } if (mAnimator.getAnimatedValue()!=null){ int i = (int)mAnimator.getAnimatedValue(); canvas.drawArc(mRectF,90-i,i*2,false,mPaint); //s上半边窗帘 canvas.drawArc(mRectF,270-i,i*2,false,mPaint); }} publicvoid openWindow(){ mCurtainstate = 1; mAnimator.setIntValues(0,90); mAnimator.start(); }publicvoid closeWindow(){ mCurtainstate=2; mAnimator.setIntValues((int)mAnimator.getAnimatedValue(),0); mAnimator.start(); }@Override public void onAnimationUpdate(ValueAnimator animation) { invalidate(); }@Override public void onAnimationRepeat(Animation animation) {}@Override public void onAnimationStart(Animation animation) {}@Override public void onAnimationEnd(Animation animation) { if (mCurtainstate ==1){ mCurtainstate = 0; }else if (mCurtainstate==2){ mCurtainstate=3; } } }
