MaxHeightFrameConstraintLayout

Introduction

Custom constraint and frame-layout to retain the maximum height from (any)child view or fragment. It uses the same height to display other small views or fragments with extra height.

• Use-case: If you are using framelayout in any nested-scroll view then while replacing a bigger fragment with smaller one, will result in moving scroll view resize and scrolling which can be avoid by keeping the same height of bigger fragment while showing the small one.

Normal Behaviour

MaxHeightConstraintLayout as Fragment Container

<?xml version="1.0" encoding="utf-8"?>

<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/myScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.pavneet_singh.maxchildheightlayout.MaxHeightConstraintLayout
        android:id="@+id/constraint"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
<!--        <OtherViews.../>-->

        <FrameLayout
            android:id="@+id/fragment_container"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_constraintTop_toBottomOf="@id/btn_show_green" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="@string/additional_text_nmore_data"
            android:textSize="24sp"
            app:layout_constraintTop_toBottomOf="@+id/fragment_container" />

    </com.pavneet_singh.maxchildheightlayout.MaxHeightConstraintLayout>

</androidx.core.widget.NestedScrollView>

MaxChildHeightFrameLayout as Fragment Container

MaxChildHeightFrameLayout as Parent Fragment Container

Either use MaxChildHeightFrameLayout as container or if you have more views which needs to be places right under the fragment then use

        <com.pavneet_singh.maxchildheightframelayout.MaxChildHeightFrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="2dp"
            app:layout_constraintTop_toBottomOf="@+id/btn_show_green">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical">

                <FrameLayout
                    android:id="@+id/fragment_container"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" />

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:text="@string/additional_text_nmore_data"
                    android:textSize="24sp" />
            </LinearLayout>
        </com.pavneet_singh.maxchildheightframelayout.MaxChildHeightFrameLayout>

Gradle Implementation

Add JitPack to your project build.gradle

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
   }
}

Add the dependency in the app build.gradle

dependencies {
    implementation 'com.github.Pavneet-Sing:MaxHeightFrameConstraintLayout:version'
  }

e.g :

implementation 'com.github.Pavneet-Sing:MaxHeightFrameConstraintLayout:1.0.0-beta01'
