如何避免RecyclerView ViewHolder中的内存泄漏？

public static class MyViewHolder extends RecyclerView.ViewHolder {
    // ViewHolder的代码
}

private WeakReference<MyViewHolder> viewHolderRef;

public MyAdapter(MyViewHolder viewHolder) {
    viewHolderRef = new WeakReference<>(viewHolder);
}

public void onBindViewHolder(MyViewHolder holder, int position) {
    viewHolderRef.get().bindData(data.get(position));
}

@Override
public void onViewRecycled(MyViewHolder holder) {
    // 释放资源的代码
}

public MyViewHolder(View itemView, Context context) {
    super(itemView);
    this.contextRef = new WeakReference<>(context.getApplicationContext());
}
