这是我的代码。我想在我的布局中放置 3 个 recyclerView，但它在设备上运行时速度非常慢。如果有 2 个 recyclerview 它运行流畅，但如果有 3 个很慢:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView

</LinearLayout>
如果有人遇到此类问题，请帮助我解决问题。
我尝试了 Nested scrollview 和 setNestedScrollingEnabled = false。但没有任何帮助
这是我的 Activity

mRecyclerViewPopularGoods.setLayoutAnimation(layoutAnimationController);
}
if (result.size() >= 2 && null != result.get(1)) {

}
}
@Override
public void stopProgress() {
getLoadingDialog().hideDialog();
}
@Override
public void onProductClicked(Product product) {
mNavigator.toProductActivity(getContext(),product);

}
有没有错误？
最佳答案
尝试以下 -
尝试将所有 View 放在 NestedScrollView 中，即 Root View 。
设置 recyclerView.setNestedScrollingEnabled(false);对于您的 xml 中的两个 recyclerView。
