Nit*_*hin 6 android android-layout android-constraintlayout
请看看我的xml:
<android.support.constraint.ConstraintLayout
android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize">
<RelativeLayout
android:id="@+id/layout_info"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="@color/colorPrimaryDark"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<include
layout="@layout/page"
android:layout_width="match_parent"
android:layout_height="0dp"/>
</android.support.constraint.ConstraintLayout>

我无法添加约束<include>.该app命名空间不起作用(它的工作原理为RelativeLayout)和自动填充不显示约束属性.我希望包含的布局高度是其余的空间ConstraintLayout,但是如何在没有约束的情况下做到这一点!请帮忙.
试试这个
<android.support.constraint.ConstraintLayout
android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize">
<RelativeLayout
android:id="@+id/layout_info"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="@color/colorPrimaryDark"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<include
layout="@layout/page"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"

在<include>标签中添加约束时,我们必须使用android:layout_width和android:layout_height这两个属性。
