我的问题是工具栏崩溃只有当我搬到RecyclerView外面时。
答案 0 :(得分:0)
这个解决方案解决了我的问题。
所以,简单地说,当Appbar完全展开时,不允许回收器视图滚动,我们将使用NestedScrollView中的滚动,否则Recycler View将正常滚动。
appBarLayout.addOnOffsetChangedListener(new AppBarStateChangeListener() {
@Override
public void onStateChanged(AppBarLayout appBarLayout, State state) {
if (state == State.COLLAPSED)
mRecyclerView.setNestedScrollingEnabled(true);
if (state == State.EXPANDED)
mRecyclerView.setNestedScrollingEnabled(false);
}
});
