1、效果圖


2、幀動畫的簡要代碼
private ImageView bgAnimView;private AnimationDrawable mAnimationDrawable;//初始化mAnimationDrawable = new AnimationDrawable();bgAnimView = new ImageView(mContext);bgAnimView.setBackgroundDrawable(getAnimationDrawable(mAnimationDrawable));params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);params.topMargin = Util.Div(176 + 58);params.gravity = Gravity.CENTER_HORIZONTAL;addView(bgAnimView, params);private AnimationDrawable getAnimationDrawable(AnimationDrawable mAnimationDrawable) {int duration = 50;mAnimationDrawable.addFrame(mContext.getResources().getDrawable(R.drawable.loading1), duration);mAnimationDrawable.addFrame(mContext.getResources().getDrawable(R.drawable.loading2), duration);mAnimationDrawable.addFrame(mContext.getResources().getDrawable(R.drawable.loading3), duration);mAnimationDrawable.setOneShot(false);return mAnimationDrawable;}//動畫開始public void animLoadingStart() {this.setVisibility(View.VISIBLE);if (mAnimationDrawable != null) {mAnimationDrawable.start();}}//動畫結束public void animLoadingEnd() {if (mAnimationDrawable != null) {mAnimationDrawable.stop();}

3、擴展：

//X軸平移public void animY(int y, int nextY, int duration) {LinearInterpolator ll = new LinearInterpolator(); //勻速ObjectAnimator animator = ObjectAnimator.ofFloat(yourView, "translationY", 0, 300);//300若為負值，就是向上平移animator.setDuration(duration);animator.setInterpolator(ll);animator.start();}//Y軸平移public void animX(int x, int nextX, int duration) {LinearInterpolator ll = new LinearInterpolator();ObjectAnimator animator = ObjectAnimator.ofFloat(yourView, "translationX", x, nextX);animator.setDuration(duration);animator.setInterpolator(ll);animator.start();}//縱向壓縮0.5倍LinearInterpolator ll = new LinearInterpolator();//勻速ScaleAnimation scaleAnimation = new ScaleAnimation(1, 1, 1, 0.5f);//默認從（0,0）scaleAnimation.setDuration(500);scaleAnimation.setInterpolator(ll);scaleAnimation.setFillAfter(true);chartView.startAnimation(scaleAnimation);//橫向壓縮0.5倍LinearInterpolator ll = new LinearInterpolator();ScaleAnimation scaleAnimation = new ScaleAnimation(1, 0.5f, 1, 1);//默認從（0,0）scaleAnimation.setDuration(500);scaleAnimation.setInterpolator(ll);scaleAnimation.setFillAfter(true);chartView.startAnimation(scaleAnimation);
