Android 添加到购物车动画(附源码)

最近项目有一个签到功能,类似于添加购物车功能,于是自己通过动画来实现这一功能,废话不多说,先上截图


gif有点卡针,需要的话我会在后面附上源码。现在就上代码了,代码注释比较详细,不懂得可以自己百度或者留言和我一起讨论,毕竟自己理解才是最好的学习之路

shop.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {int[] start_location = new int[2];// 一个整型数组,用来存储按钮的在屏幕的X、Y坐标v.getLocationInWindow(start_location);// 这是获取购买按钮的在屏幕的X、Y坐标(这也是动画开始的坐标)ImageView buyImg = new ImageView(getApplicationContext());// buyImg是动画的图片,我的是一个小球(R.drawable.sign)buyImg.setImageResource(R.drawable.sign);// 设置buyImg的图片setAnim(buyImg, start_location);// 开始执行动画}});

执行动画代码

private void setAnim(final View v, int[] start_location) {ViewGroup anim_mask_layout = null;anim_mask_layout = createAnimLayout();//创建动画视图anim_mask_layout.addView(v);//把动画小球添加到动画层final View view = addViewToAnimLayout(anim_mask_layout, v,start_location);int[] end_location = new int[2];// 这是用来存储动画结束位置的X、Y坐标imageView.getLocationInWindow(end_location);// shopCart是那个购物车// 计算位移int endX = end_location[0]- start_location[0];// 动画位移的X坐标int endY = end_location[1] - start_location[1];// 动画位移的y坐标TranslateAnimation translateAnimationX = new TranslateAnimation(0,endX, 0, 0);translateAnimationX.setInterpolator(new LinearInterpolator());translateAnimationX.setRepeatCount(0);// 动画重复执行的次数translateAnimationX.setFillAfter(true);TranslateAnimation translateAnimationY = new TranslateAnimation(0, 0,0, endY);translateAnimationY.setInterpolator(new AccelerateInterpolator());translateAnimationY.setRepeatCount(0);// 动画重复执行的次数translateAnimationX.setFillAfter(true);AnimationSet set = new AnimationSet(false);set.setFillAfter(false);set.addAnimation(translateAnimationY);set.addAnimation(translateAnimationX);set.setDuration(800);// 动画的执行时间view.startAnimation(set);// 动画监听事件set.setAnimationListener(new AnimationListener() {// 动画的开始@Overridepublic void onAnimationStart(Animation animation) {v.setVisibility(View.VISIBLE);}@Overridepublic void onAnimationRepeat(Animation animation) {// TODO Auto-generated method stub}// 动画的结束@Overridepublic void onAnimationEnd(Animation animation) {v.setVisibility(View.GONE);}});}

创建动画视图代码

/** * @Description: 创建动画层 * @param * @return void * @throws */private ViewGroup createAnimLayout() {ViewGroup rootView = (ViewGroup) this.getWindow().getDecorView();LinearLayout animLayout = new LinearLayout(this);LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT);animLayout.setLayoutParams(lp);animLayout.setId(Integer.MAX_VALUE);animLayout.setBackgroundResource(android.R.color.transparent);rootView.addView(animLayout);return animLayout;}

将视图添加到动画布局中去---addViewToAnimLayout()

private View addViewToAnimLayout(final ViewGroup vg, final View view,int[] location) {int x = location[0];int y = location[1];LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);lp.leftMargin = x;lp.topMargin = y;view.setLayoutParams(lp);return view;}

好了,到了这里,基本代码就实现了,具体位置可以自己调节,我这边只是实现一个比较简单的DEMO。可以根据自己的需求进行布局的改变
