本篇是添加银行卡动画的最后一篇,要实现的效果如下
添加银行卡动画
首先观察动画,动画开始的时候将上一页的phoneLayout移除,然后这个电话的背景图向下+放大的效果,然后是短信验证码view(viewCode)添加到电话背景图上,里面的内容执行scale动画。
我们先来做这个电话背景图片向下+放大的效果,这次我们使用的是属性动画,所以在res下新建animator,然后新建thirdainm.xml,代码如下:
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:ordering="together" > <objectAnimator android:propertyName="translationY" android:duration="500" android:valueFrom="0" android:valueTo="150" /> <objectAnimator android:propertyName="scaleX" android:duration="500" android:valueFrom="1.0" android:valueTo="1.2" /> <objectAnimator android:propertyName="scaleY" android:duration="500" android:valueFrom="1.0" android:valueTo="1.2" /> </set>
然后在activity中对动画进行监听,在动画开始时移除phoneLayout,动画结束时添加viewCode到手机屏幕上
thirdAnim = AnimatorInflater.loadAnimator(this, R.animator.thirdanim); thirdAnim.addListener(new MyAnimationListener() { @Override public void onAnimationStart(Animator animation) { phoneLayout.setVisibility(View.GONE);//将上一页的phoneLayout移除 } @Override public void onAnimationEnd(Animator animation) { //这里添viewCode到手机屏幕上,主要是计算位置 }
viewCode代码如下:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:background="@color/white" ><RelativeLayout android:id="@+id/rl_addbank_code" android:padding="5dp" android:background="@color/colorBule3" android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:visibility="invisible" android:id="@+id/addbank_code_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="@mipmap/icon_xiaoxi" /> <TextView android:visibility="invisible" android:textColor="@color/white" android:textSize="10sp" android:text="新的短消息" android:id="@+id/addbank_code_tv1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:layout_toRightOf="@+id/addbank_code_image" /> <TextView android:visibility="invisible" android:textColor="@color/white" android:textSize="10sp" android:layout_marginTop="3dp" android:layout_marginLeft="5dp" android:layout_below="@+id/addbank_code_tv1" android:layout_toRightOf="@+id/addbank_code_image" android:text="您收到的验证码xxxxxx" android:id="@+id/addbank_code_tv2" android:layout_width="wrap_content" android:layout_height="wrap_content" /></RelativeLayout></LinearLayout>
然后在onAnimationEnd中添加viewCode
public void onAnimationEnd(Animator animation) { View viewCode= AddBankCardActivity.this.getLayoutInflater().inflate(R.layout.view_addbank_code, null); final ImageView ivMessage = (ImageView) viewCode.findViewById(R.id.addbank_code_image); final TextView tvMess1 = (TextView) viewCode.findViewById(R.id.addbank_code_tv1); final TextView tvMess2 = (TextView) viewCode.findViewById(R.id.addbank_code_tv2); RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT); param.width = (int) (ivPhone.getWidth() - ivPhone.getWidth() * 0.116); param.height = (int) (ivPhone.getHeight() * 0.3); param.leftMargin = (int) (ivPhone.getLeft() + ivPhone.getWidth() * 0.058); param.topMargin = (int) (ivPhone.getTop() + ivPhone.getHeight() * 0.251); rlContent.addView(viewCode, param);//短信验证码view(viewCode)添加到电话背景图上}
其中最主要的就是计算viewCode的LayoutParams,需要根据ivphone的宽高和margin来计算出view的LayoutParams。然后就是viewCode中的imageview和两个textview依次执行scale动画,scale动画如下
<set xmlns:android="http://schemas.android.com/apk/res/android"> <scale android:fillAfter="true" android:duration="200" android:fromXScale="0" android:fromYScale="0" android:toXScale="1" android:toYScale="1" /></set>
activity中的依次执行动画,并在动画结束后,将view显示出来
Animation ivAnim = AnimationUtils.loadAnimation(AddBankCardActivity.this, R.anim.scaleanim); final Animation tvAnim1 = AnimationUtils.loadAnimation(AddBankCardActivity.this, R.anim.scaleanim); final Animation tvAnim2 = AnimationUtils.loadAnimation(AddBankCardActivity.this, R.anim.scaleanim); ivMessage.startAnimation(ivAnim); ivAnim.setAnimationListener(new MyAnimationListener() { @Override public void onAnimationEnd(Animation animation) { ivMessage.setVisibility(View.VISIBLE); tvMess1.startAnimation(tvAnim1); } }); tvAnim1.setAnimationListener(new MyAnimationListener() { @Override public void onAnimationEnd(Animation animation) { tvMess1.setVisibility(View.VISIBLE); tvMess2.startAnimation(tvAnim2); } }); tvAnim2.setAnimationListener(new MyAnimationListener() { @Override public void onAnimationEnd(Animation animation) { tvMess2.setVisibility(View.VISIBLE); } }); } });
好了,到此为止添加银行卡动画已经全部实现完毕,但是在实际项目中,你可能会要返回上一步修改卡号或者手机号码,这个时候你就要做返回的动画,效果正好跟咱们这个反着来,有兴趣的小伙伴可以自己动手实现一下,好了代码已经上传,欢迎star
