[Android] weex waterfall 组件支持ViewHolder复用吗

版本：安卓 org.apache.weex:sdk_legacy:0.28.0
使用waterfall时发现内存占用很高，查看BaseListComponent的源码发现有这样一段代码：
checkRecycledViewPool中对RecycledViewPool的大小设置为了0，是不是意味着weex吧recyclerView的复用给静止了，所以就导致每次加载更多item时，都是重新创建了ViewHolder，没有复用viewHolder
```
private void checkRecycledViewPool(int viewType) {
try {
if (mViewTypes.size() > MAX_VIEWTYPE_ALLOW_CACHE)
mAllowCacheViewHolder = false;

if (mDownForBidCacheViewHolder)
if (getHostView() != null && getHostView().getInnerView() != null)
getHostView().getInnerView().getRecycledViewPool().setMaxRecycledViews(viewType, 0);

if (!mDownForBidCacheViewHolder) {
if (!mAllowCacheViewHolder) {
if (getHostView() != null && getHostView().getInnerView() != null) {
for (int i = 0; i < mViewTypes.size(); i++) {
getHostView().getInnerView().getRecycledViewPool().setMaxRecycledViews(mViewTypes.keyAt(i), 0);
}
mDownForBidCacheViewHolder = true;
}
}
}
} catch (Exception e) {
WXLogUtils.e(TAG, "Clear recycledViewPool error!");
}
}
```

Start by reading BaseListComponent.checkRecycledViewPool and the surrounding RecycledViewPool handling in the Android SDK version org.apache.weex:sdk_legacy:0.28.0. Reproduce the waterfall memory behavior and verify whether setting the pool size to zero affects ViewHolder reuse; document the finding and identify the appropriate fix or clarification.
