Question

我正在使用recyclelerview，在向下滚动后崩溃并发出OOM异常。

01-09 02：32：56.169 W / System.err（6816）：java.lang.OutOfMemoryError：无法分配带有0个空闲字节的43字节分配和3GB直到OOM

如何改进我的代码？我需要处理东西还是自动发生？因为我在谷歌搜索后找到了不同的答案。

    public override RecyclerView.ViewHolder
               OnCreateViewHolder(ViewGroup parent, int viewType)
    {
        View itemView = LayoutInflater.From(parent.Context).
                    Inflate(Resource.Layout.MomentListItem, parent, false);
        MomentViewHolder vh = new MomentViewHolder(itemView);
        vh.llMain.Click += (object sender, EventArgs e) =>
        {
            //Check if you don't get a negative position from the header.
            if (vh.AdapterPosition >= 0)
            {
                //Fix the position to leave out the header as a moment
                int ajustedPosition = vh.AdapterPosition;

                // Create a new fragment and a transaction.
                FragmentTransaction fragmentTx = mActivity.FragmentManager.BeginTransaction();
                MomentFragment aDifferentDetailsFrag = new MomentFragment();

                // Create a bundle to pack the argumants.
                Bundle utilBundle = new Bundle();
                utilBundle.PutString("ID", mItems[ajustedPosition].momentID);

                // Commit the transaction.
                fragmentTx.Commit();

我已经看到了类似的问题，问题在于图片渲染。尝试使图像更小。还尝试使用Picasso组件来渲染图像。

P.S。：我的意思是在视图内部较小，但在服务器端。
