我最近决定将我的应用程序移到使用新的支持设计库,最近发现了一个非常讨厌的错误。
假设我有一个CoordinatorLayout托管AppBarLayout和任何可滚动视图,无论是ViewPager,NestedScrollView,还是具有所需滚动行为的RecyclerView;选择显示一个显示键盘的对话框片段会导致AppBarLayout与滚动视图断开连接,并且它们不再滚动在一起。
此外,滚动视图被强制调整到底部屏幕的一半,而AppBar布局占据了上半部分,尽管它不需要它。

编辑:
将Activity中键盘的softInputMode设置为" adjustPan"解决了这个问题。显然,CoordinatorLayout不喜欢通过键盘动态调整大小。
有问题的XML看起来像这样,但我有多个XML变体表现出这种行为,其中的共同元素都是他们使用的是CollapsingToolbarLayout:

Tunji_D提供的答案将解决问题,但不一定是潜在的问题。
协调器布局上的滚动行为现在在其子视图的无效步骤中出现问题:https://code.google.com/p/android/issues/detail?id=176373#c5
因此,为了修复它,请使用junya提供的此解决方法,并使用
设置视图的行为app:layout_behavior="com.app.common.PatchedScrollingViewBehavior"
并使用:
public class PatchedScrollingViewBehavior extends AppBarLayout.ScrollingViewBehavior {
public PatchedScrollingViewBehavior() {
super();
}
public PatchedScrollingViewBehavior(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean onMeasureChild(CoordinatorLayout parent, View child, int parentWidthMeasureSpec, int widthUsed, int parentHeightMeasureSpec, int heightUsed) {
if(child.getLayoutParams().height == -1) {
List dependencies = parent.getDependencies(child);
if(dependencies.isEmpty()) {
return false;
}
AppBarLayout appBar = findFirstAppBarLayout(dependencies);
if(appBar != null && ViewCompat.isLaidOut(appBar)) {
if(ViewCompat.getFitsSystemWindows(appBar)) {
ViewCompat.setFitsSystemWindows(child, true);
}
int scrollRange = appBar.getTotalScrollRange();
// int height = parent.getHeight() - appBar.getMeasuredHeight() + scrollRange;
int parentHeight = View.MeasureSpec.getSize(parentHeightMeasureSpec);
int height = parentHeight - appBar.getMeasuredHeight() + scrollRange;
int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.AT_MOST);
parent.onMeasureChild(child, parentWidthMeasureSpec, widthUsed, heightMeasureSpec, heightUsed);
return true;
}
}
return false;
}
private static AppBarLayout findFirstAppBarLayout(List<View> views) {
int i = 0;
for(int z = views.size(); i < z; ++i) {
View view = (View)views.get(i);
if(view instanceof AppBarLayout) {
return (AppBarLayout)view;
}
}
return null;
}
}
