NestedScrollView陷入recyclerview

标签： android android-recyclerview android-nestedscrollview

我正在使用NestedScrollView，并且有3个recyclerviews。我正在解析json并在recyclerview中设置数据，现在的问题是，在我的上一个recyclerview中，我设置了分页功能，因此直到未为该recyclerview获取数据之前，我的整个屏幕都被卡住并冻结了。我为此尝试了另一种解决方案。但它不起作用，我发现结果没有变化。有人可以帮我吗？

为RecyclerView中的每个NestedScrollView运行以下代码

ViewCompat.setNestedScrollingEnabled(recyclerView, false);

答案 1 :(得分：0)

尝试此代码，效果很好，

rvCompanies.setHasFixedSize(true);
LinearLayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
rvCompanies.setLayoutManager(layoutManager);
rvCompanies.setNestedScrollingEnabled(false); // important
