本文講述了Java實現幀動畫的實例代碼。分享給大家供大家參考，具體如下：
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);點擊打開素材下載地址
