Custom toolbar using ConstraintLayout in android

Question

I am trying to create my own custom

Toolbar

for my project. Currently I am using

RelativeLayout

to create it. But I wanna avoid deep hierarchy of

Views

. So I wanna create it using

ConstrainLayout

. How can I achieve the following in

ConstraintLayout

.

Code for the above layout:

<RelativeLayout

            android:id="@+id/customAppBarLayout"

            android:layout_width="match_parent"

            android:layout_height="?attr/actionBarSize"

            android:paddingEnd="10dp"

            android:paddingStart="10dp">



            <ImageView

                android:id="@+id/toolbarCloseButton"

                android:layout_width="30dp"

                android:layout_height="30dp"

                android:layout_centerVertical="true"

                android:adjustViewBounds="true"

                app:srcCompat="@drawable/ic_cancel" />



            <TextView

                android:id="@+id/toolbarTitle"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:layout_centerVertical="true"

                android:layout_marginStart="15dp"

                android:layout_toEndOf="@+id/toolbarCloseButton"

                android:textColor="#000"

                android:textSize="18sp"

                tools:text="Puzzle" />



            <RelativeLayout

                android:layout_width="30dp"

                android:layout_height="30dp"

                android:layout_alignParentEnd="true"

                android:layout_centerVertical="true">



                <ImageView

                    android:id="@+id/coinIcon"

                    android:layout_width="match_parent"

                    android:layout_height="match_parent"

                    android:layout_centerHorizontal="true"

                    android:layout_centerVertical="true"

                    android:paddingBottom="2dp"

                    android:paddingRight="2dp"

                    app:srcCompat="@drawable/ic_single_coin"

                    tools:ignore="MissingPrefix" />



                <TextView

                    android:id="@+id/prizeSize"

                    android:layout_width="16dp"

                    android:layout_height="16dp"

                    android:layout_alignParentBottom="true"

                    android:layout_alignParentEnd="true"

                    android:layout_centerInParent="true"

                    android:background="@drawable/circular_background"

                    android:focusable="true"

                    android:focusableInTouchMode="true"

                    android:freezesText="true"

                    android:gravity="center"

                    android:marqueeRepeatLimit="marquee_forever"

                    android:maxEms="20"

                    android:maxLines="1"

                    android:padding="1dp"

                    android:scrollHorizontally="true"

                    android:textColor="#fff"

                    android:textSize="6sp"

                    tools:text="100" />

            </RelativeLayout>

        </RelativeLayout>

How this can be done in

ConstraintLayout

?

I wrote a simple layout. You can see my code to improve your layout. Hope it helps:

<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content"
    android:background="#00ffff">

    <TextView
        android:id="@+id/tv"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#0000ff"
        android:gravity="center_vertical"
        android:text="TextView"
        android:textColor="@android:color/white"
        android:textSize="20sp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toRightOf="@+id/iv_1"
        app:layout_constraintRight_toLeftOf="@+id/iv_2"
        app:layout_constraintTop_toTopOf="parent" />

    <ImageView
        android:id="@+id/iv_1"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:background="@android:color/holo_red_dark"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent" />


    <ImageView
        android:id="@+id/iv_2"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:background="#00ff00"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>
