ConstraintLayout高度调整不当
我认为我很好地控制了Constraint Layout。但这个高度问题很奇怪。
问题
ConstraintLayout @id/boarding @id/progress_layout正确占据@id/take_off_button和@id/boarding_counter之间的全高。但它的子@id/runway和width:0dp并没有占据父母的整个高度。我已经为孩子定义了正确的属性：app:layout_constraintTop_toTopOf="parent",app:layout_constraintBottom_toBottomOf="parent"，<?xml version="1.0" encoding="utf-8"?>

，他们只是采取部分随机高度。
请帮忙
这是我的布局文件，我还附上了截图：
@id/taxis更新
更改库版本但暂时有效。当我在Recycler View private async void SaveasGIF(object sender, RoutedEventArgs e)
{
var savePicker = new Windows.Storage.Pickers.FileSavePicker();
savePicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary;
savePicker.FileTypeChoices.Add("Gif with embedded ISF", new[] { ".gif" });
Windows.Storage.StorageFile file = await savePicker.PickSaveFileAsync();
if (null != file)
{
try
{
using (Windows.Storage.Streams.IRandomAccessStream stream = await file.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite))
{
// Truncate any existing stream in case the new file
// is smaller than the old file.
stream.Size = 0;
await MyInkCanvas.InkPresenter.StrokeContainer.SaveAsync(stream);
}
//MainPage.NotifyUser("File has been saved!", NotifyType.StatusMessage);
}
catch (Exception ex)
{
//MainPage.NotifyUser(ex.Message, NotifyType.ErrorMessage);
}
}
SaveGIF.IsChecked = false;
}
中添加项目时，高度再次降低到一半。

更新到ConstraintLayout 1.1.0-beta3以解决此问题：
compile 'com.android.support.constraint:constraint-layout:1.1.0-beta3'
