RecyclerView滚动非常缓慢且缓慢

Question

Hey I am using recyclerview with list-card design and on every card I have an image, not a large one it weights 1.5 mb I am loading 12 cards but the scrolling is so laggy I tried using PICASSO and it didn't helped, the thing is when I replace the image with a much smaller one (300 bytes) it scrolles well but it doesn't solve my problem..

the relevant part of the cards xml is:

 <android.support.v7.widget.CardView

        android:id="@+id/card_item"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_gravity="center"

        android:clickable="true"
        card_view:cardCornerRadius="4dp">



        <RelativeLayout

            android:id="@+id/cont_card_content"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:clickable="true"
            android:background="#FFFFFF">



            <ImageView

                android:id="@+id/im_item_icon"

                android:layout_width="wrap_content"

                android:layout_height="170dp"

                android:scaleType="fitXY"

                android:layout_alignParentTop="true"
                android:layout_alignParentStart="true" />

as I was saying I tried using PICASSO and it didn't helped

Picasso.with(context).load(R.drawable.bg_partyt).into(holder.imageView);

any ideas?

Answer 1

your image is way to big.

You could try using Glide instead of picasso. It handles big images a little bit better https://github.com/bumptech/glide
