Okey, ich habe die Lösung here, fanden wir brauchen:
public class FixAppBarLayoutBehavior extends AppBarLayout.Behavior {
public FixAppBarLayoutBehavior() {
super();
}
public FixAppBarLayoutBehavior(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void onNestedScroll(CoordinatorLayout coordinatorLayout, AppBarLayout child, View target,
int dxConsumed, int dyConsumed, int dxUnconsumed, int dyUnconsumed, int type) {
super.onNestedScroll(coordinatorLayout, child, target, dxConsumed, dyConsumed,
dxUnconsumed, dyUnconsumed, type);
stopNestedScrollIfNeeded(dyUnconsumed, child, target, type);
}
@Override
public void onNestedPreScroll(CoordinatorLayout coordinatorLayout, AppBarLayout child,
View target, int dx, int dy, int[] consumed, int type) {
super.onNestedPreScroll(coordinatorLayout, child, target, dx, dy, consumed, type);
stopNestedScrollIfNeeded(dy, child, target, type);
}
private void stopNestedScrollIfNeeded(int dy, AppBarLayout child, View target, int type) {
if (type == ViewCompat.TYPE_NON_TOUCH) {
final int currOffset = getTopAndBottomOffset();
if ((dy < 0 && currOffset == 0)
|| (dy > 0 && currOffset == -child.getTotalScrollRange())) {
ViewCompat.stopNestedScroll(target, ViewCompat.TYPE_NON_TOUCH);
}
}
}
}
und in unserem AppBarLayout:
<android.support.design.widget.AppBarLayout
...
app:layout_behavior="your.package.FixAppBarLayoutBehavior">
...
</android.support.design.widget.AppBarLayout>
Dank! Du sparst meinen Tag! –
