Aligning Text View with constraint Layout


I am trying to align my textview in the constraint layout without using margins so the layout can be responsive in all the devices but so far I am stuck in positioning. Here is my code and expected output attached in the image. I just want to make the amount align slightly with currency text. This is the expected output

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

     <TextView
         android:id="@+id/year_bar_chart_total"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="Total"
         app:layout_constraintStart_toStartOf="parent"
         app:layout_constraintTop_toTopOf="parent"
         />
     <TextView
         android:id="@+id/yearBarChartCurrency"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="RM"
         app:layout_constraintEnd_toEndOf="@+id/yearBarChartAmount"
         app:layout_constraintHorizontal_bias="0.17"
         app:layout_constraintStart_toStartOf="@id/year_bar_chart_total"
         app:layout_constraintTop_toBottomOf="@id/year_bar_chart_total"
         tools:text="RM"/>
     <TextView
         android:id="@+id/yearBarChartAmount"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="tOTAL"
         app:layout_constraintHorizontal_bias="0.17"
         app:layout_constraintStart_toEndOf="@id/yearBarChartCurrency"
         app:layout_constraintTop_toBottomOf="@id/year_bar_chart_total"
         tools:text="233.34"/>

</android.support.constraint.ConstraintLayout>

Solution

  • You can use guidelines to achieve this :

    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.1" />
    
    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.1" />
    
    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.25" />
    
    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="balance"
        app:layout_constraintBottom_toTopOf="@+id/textView5"
        app:layout_constraintStart_toStartOf="@+id/guideline3" />
    
    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="RM"
        app:layout_constraintBottom_toTopOf="@+id/guideline2"
        app:layout_constraintStart_toStartOf="@+id/guideline3" />
    
    <TextView
        android:id="@+id/textView8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="233.34"
        app:layout_constraintEnd_toStartOf="@+id/guideline4"
        app:layout_constraintStart_toEndOf="@+id/textView5"
        app:layout_constraintTop_toBottomOf="@+id/textView4" />
    

    It will look like this:

    I must emphasize one thing that really bothered me:

    "margins so the layout can be responsive in all the devices" - this is not true and let me explain.

    what makes your screen responsive to all screen sizes is constraintLayout and how you use it, I agree that a large number of margin in dp will make your screen not responsive but small margins are recommended to use in google material design - it will actually give your app better look and prevent your views from being attached directly to the parent border.
