下方放置ViewPager+Fragment作为滚动布局
你好，如果下方的滚动布局换成ViewPager+Fragment这种，Fragment里放RecyclerView，RecyclerView的Adapter的ItemView里有图片的话，上滑时，会出现重影，闪一下，如果去掉自定义的bahavior，就没问题，请作者帮忙看下 谢谢~
这个是Activity里的布局文件
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" app:statusBarBackground="@android:color/transparent" android:layout_height="match_parent">

这个是ViewPager里的Fragment的布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
这个是Fragment里Adapter的item_layout
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="wrap_content" app:cardBackgroundColor="@color/white" app:cardElevation="20dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:background="@drawable/default_pic"
android:scaleType="centerCrop" />
<View
android:layout_width="match_parent"

android:paddingRight="5dp">

android:gravity="bottom"
android:singleLine="true"
android:textColor="@color/text_color"
app:dashLineStyle="normalBlack" />
<LinearLayout
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.huapu.huafen.views.CommonPriceView
android:id="@+id/cpvPrice"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
/>
<TextView
android:id="@+id/tvLikeCount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="@drawable/btn_item_like_select"
android:drawablePadding="3dp"
android:singleLine="true"
android:text="1111"

</LinearLayout>
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
这个是Adapter的部分代码
@Override public HomePageViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { HomePageViewHolder viewHolder = new HomePageViewHolder(LayoutInflater.from(fragment.getActivity()). inflate(R.layout.item_home_page, parent, false)); LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) viewHolder.ivPhoto.getLayoutParams(); lp.height = CommonUtils.getScreenWidth()/2; viewHolder.ivPhoto.setLayoutParams(lp); return viewHolder; }
@Override
public void onBindViewHolder(HomePageViewHolder holder, int position) {
final GoodsInfo item = data.get(position);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
if(item!=null){
if(!ArrayUtil.isEmpty(item.getGoodsImgs())){
String url = item.getGoodsImgs().get(0);
String tag = (String) holder.ivPhoto.getTag();
if(TextUtils.isEmpty(tag)||!tag.equals(url)){
holder.ivPhoto.setTag(url);
ImageLoaderRoundManager.getImageLoader().displayImage(url,
holder.ivPhoto, ImageLoaderRoundManager.getImageOptions());
}
}else{
holder.ivPhoto.setImageResource(R.drawable.default_pic);
}
holder.dlvGoodsName.setData(item.getGoodsBrand(),item.getGoodsName());
holder.cpvPrice.setData(item);
holder.tvLikeCount.setText(item.getWantCount()+"");
}
}
activity要透明状态栏，然后那个imageview设置android:fitsSystemWindows="true" 这样修改后应该就好了
