Constraintlayout - place textview beneath imageview causing unexpected grows
I want to have 4 images that takes up the parent's width and the images should divide the total width by 4 with some offset. This is what it looks like:
Now I want to place four textlabels beneath them. Each ImageView should have a textlabel beneath it. This is the problem: when I try to center a TextView, 1 of the 4 images just randomly grows. I can not set the images to have all equal width/heights.
This is what it should look like:
How can I place and center the TextViews beneath the ImageViews? This is the XML:
<?xml version="1.0" encoding="utf-8"?>

You can chain TextView widgets the same way you did with image views.
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/tv3"
app:layout_constraintTop_toTopOf="@+id/tv1" />
</android.support.constraint.ConstraintLayout>
Don't forget to add this line to your gradle build file
implementation 'com.android.support.constraint:constraint-layout:1.1.0-beta3'
Hope this helps!

For the results shown in above image, the most easy way is doing it like this ,
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/frame_1"
android:layout_width="0dp"
android:layout_height="150dp"
android:layout_marginRight="4dp"
android:orientation="vertical"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="@+id/frame_2"
app:layout_constraintTop_toTopOf="parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="120dp"
android:background="#eee" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Text1" />
</LinearLayout>
<LinearLayout
android:id="@+id/frame_2"
android:layout_width="0dp"
android:layout_height="150dp"
android:layout_marginRight="2dp"
android:orientation="vertical"
app:layout_constraintLeft_toRightOf="@+id/frame_1"
app:layout_constraintRight_toLeftOf="@+id/frame_3"
app:layout_constraintTop_toTopOf="parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="120dp"
android:background="#eee" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"

app:layout_constraintLeft_toRightOf="@+id/frame_2"
app:layout_constraintRight_toLeftOf="@+id/frame_4"
app:layout_constraintTop_toTopOf="parent">
<ImageView
android:layout_width="match_parent"
