商城之商品列表
1.商品排序功能实现(TabLayout)
1. compile 'com.android.support:design:23.0.1'
2. Tips :首页点击图片反转动画
//点击图片反转效果
private void anim(final View v){
ObjectAnimator animator = ObjectAnimator.ofFloat(v, "rotationX", 0.0F, 360.0F)
.setDuration(200);
animator.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
HomeCampaign campaign = mDatas.get(getLayoutPosition());
switch (v.getId()){
case R.id.imgview_big:
mListener.onClick(v, campaign.getCpOne());
break;
case R.id.imgview_small_top:
mListener.onClick(v, campaign.getCpTwo());
break;
case R.id.imgview_small_bottom:
mListener.onClick(v,campaign.getCpThree());
break;
}
}
});
animator.start();
}
}
3.布局
