My FrameLayoutinside a CoordinatorLayoutdoes not want to be wrap_content. When I select wrap_contentwith the ui tool, it does not set it to wrap_content, but sets a specific 48dp height .
I also tried installing it directly in the xml file and it works ... Until I open the file. I suppose the AS editor does some work and reset its height to 48dp .
This is what my layout looks like:
<layout
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<import type="android.view.View" />
<variable
name="viewModel"
type="com.mydomain.relationViewModel" />
</data>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true"
android:layout_centerInParent="true"
android:visibility="@{viewModel.isLoading() ? View.VISIBLE : View.GONE}"/>
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="@{viewModel.isLoading() ? View.INVISIBLE : View.VISIBLE}">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="@+id/hint"

<FrameLayout

android:layout_height="48dp"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintLeft_toLeftOf="parent"

android:layout_marginEnd="16dp"
android:layout_marginRight="16dp"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintTop_toBottomOf="@+id/search_patient_title">
</FrameLayout>
<Button
android:text="@string/cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/cancel"
app:layout_constraintLeft_toLeftOf="parent"
style="@style/buttonStyle"
android:layout_marginTop="8dp"
app:layout_constraintTop_toBottomOf="@+id/search_fragment_container" />
<TextView
android:text="@string/search_patient"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/search_patient_title"
android:layout_marginTop="8dp"
app:layout_constraintTop_toBottomOf="@+id/spinner"
android:layout_marginStart="16dp"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginLeft="16dp"
tools:text="Recherche du patient"
style="@style/myTitle" />
</android.support.constraint.ConstraintLayout>
</RelativeLayout>
</layout>
And here is a screenshot of my plan (where is the selected layout - FrameLayout):
Thanks for the extra help!
EDIT
Got the same problem with CardView (seems legitimate as it is a child of FrameLayout).
