我的应用程序的设计
屏幕 - 1
<NestedScrollview>
<LinearLayout orientation:horizontal">
<RecyclerView-1>
<Framelayout>(contains Recyclerview-2)
</NestedScroll>
屏幕 - 2
<NestedScrollview>
<LinearLayout orientation:horizontal">
<RecyclerView-1>
<Framelayout> (fragment changed, contains Recyclerview-3)
</NestedScroll>
现在,如果用户在屏幕1上,那么recyclelerview将同时滚动,但是如果用户滚动RV1,则在屏幕2上,如果RV3滚动,则RV1将同样滚动,然后滚动RV3。尝试了所有类型的停止滚动,但无法停止嵌套滚动视图的滚动。

您必须创建一个在触摸和滚动事件上不执行任何操作的新类:
public class LockableNestedScrollView extends NestedScrollView {
// by default is scrollable
private boolean scrollable = true;
public LockableNestedScrollView(@NonNull Context context) {
super(context);
}
public LockableNestedScrollView(@NonNull Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
}
public LockableNestedScrollView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
return scrollable && super.onTouchEvent(ev);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return scrollable && super.onInterceptTouchEvent(ev);
}
public void setScrollingEnabled(boolean enabled) {
scrollable = enabled;
}
}
接下来,在布局中,通过新类更改NestedScroll:
<your.package.name.path.LockableNestedScrollView>
<LinearLayout
orientation:"horizontal"
android:id="@+id/scroll_name">
<RecyclerView-1>
<Framelayout>(contains Recyclerview-2)
</your.package.name.path.LockableNestedScrollView>
最后在您的活动中:
LockableNestedScrollView myScrollView = (LockableNestedScrollView) findViewById(R.id.scroll_name);
myScrollView.setScrollingEnabled(false);
我希望它可以帮助其他人。
