问题描述
我在布局中使用 NestedScrollView，并尝试使用 CollapsingToolbarLayout 设计支持库中的新 CoordinatorLayout.
I'm using a NestedScrollView in a layout, and am attempting to use the new CoordinatorLayout from the design support library for CollapsingToolbarLayout.
我的布局文件如下所示:
My layout file looks like this:

当我尝试滚动时，有时它不起作用.原因是，具有点击事件的其他布局元素正在消耗触摸事件.基本上 EditText、RadioButton、Button 正在消耗触摸事件.有什么建议可以解决这个问题吗?
When i try to scroll, sometimes it doesn't work. reason for this is, other elements of layout with click events are consuming the touch event. Basically EditText, RadioButton, Button are consuming touch events. Any Suggestions to solve this problem ?
推荐答案
我遇到了同样的问题.它仅在 NestedScrollView 内容高度小于设备屏幕高度时发生.因此，解决方法是对 NestedScrollView 内的视图使用 setMinimumHeight(..) 方法，使其调整为屏幕高度:
I had the same problem. It happens only when NestedScrollView content height is less than height of device screen. So the workaround is to use setMinimumHeight(..) method for the view inside your NestedScrollView to make it resize to screen height:
DisplayMetrics displaymetrics = new DisplayMetrics();
getBaseActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int screenHeight = displaymetrics.heightPixels;
int actionBarHeight = 0;
TypedValue tv = new TypedValue();
if (getBaseActivity().getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
view.setMinimumHeight(screenHeight - actionBarHeight);
其中 view 是您的 RelativeLayout
它对我来说很好用.希望对你有帮助
