Different size of ImageView on different devices

I have a little problem with ImageView on differents screens with different dpi like this:

screen from emulator

screen from real device

On second screen there are original dimensions of imageviews. But on first screen images are bigger and moved out. How i can set proportional dimensions and margins to ImageView.

Here is my code:

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/textLayoutIntro">

        <ImageView
            android:id="@+id/first_slide_second_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:scaleType="fitCenter"
            android:src="@mipmap/first_slide_second_image"
            android:layout_alignParentStart="true"
            android:layout_alignStart="@+id/firstSlideTelephone"
            android:layout_marginTop="100dp"
            android:layout_marginStart="20dp"/>

        <ImageView
            android:id="@+id/first_slide_third_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@mipmap/first_slide_third_image"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true"
            android:layout_alignParentEnd="true"
            android:layout_alignEnd="@+id/firstSlideTelephone"
            android:layout_marginEnd="30dp"
            android:layout_marginTop="100dp"/>


        <ImageView
            android:id="@+id/firstSlideTelephone"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@mipmap/first_slide_telephone"
            android:layout_centerInParent="true"
            android:adjustViewBounds="true"
            android:scaleType="centerInside"/>


        <ImageView
            android:id="@+id/first_slide_first_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:scaleType="fitCenter"
            android:src="@mipmap/first_slide_first_image"
            android:layout_marginStart="-30dp"
            android:layout_alignParentStart="true"
            android:layout_alignParentBottom="true"
            android:maxWidth="138dp"
            android:maxHeight="138dp"/>


        <ImageView
            android:id="@+id/first_slide_fourth_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentEnd="true"
            android:adjustViewBounds="true"
            android:scaleType="fitCenter"
            android:src="@mipmap/first_slide_fourth_image"
            android:layout_alignParentBottom="true"
            android:layout_marginBottom="100dp"/>


    </RelativeLayout>

Thanks in advance)

It's possible to solve many ways. The above bros already said possible to solve by Constraint layout.

It's also possible to solve by Linear layout. Just use weight_sum. Add 2 View add the top and bottom and at the middle add your image. Weight perfectly work dynamically (may you know).

But if I was in this situation, I would be solved it using sdp & ssp library. The library most of the time works perfectly.

only for font/text size: ssp. & For any others except font: sdp

Instead of RelativeLayout, use constraintlayout with vertical and horizontal guidelines. That way, the content sizes up or down to whatever device screen size. Like the sample below.

<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:id="@+id/parent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorAccent"
    android:clickable="true"
    tools:context="com.example.example.Fragments.ExampleFragment">


    <android.support.constraint.Guideline
        android:id="@+id/fragment_guideline_v_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.1" />

    <android.support.constraint.Guideline
        android:id="@+id/fragment_guideline_v_2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.9" />


    <android.support.constraint.Guideline
        android:id="@+id/fragment_guideline_h_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.1" />

    <android.support.constraint.Guideline
        android:id="@+id/fragment_guideline_h_2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.9" />

        <ImageView
            android:id="@+id/imageview"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:contentDescription="@string/none"
            app:layout_constraintStart_toEndOf="@+id/fragment_guideline_h_1"
            app:layout_constraintEnd_toStartOf="@+id/fragment_guideline_h_2"
            app:layout_constraintTop_toBottomOf="@+id/fragment_guideline_v_1"
            app:layout_constraintBottom_toTopOf="@+id/fragment_guideline_v_2"
            app:srcCompat="@drawable/forgot_password_arrow_back" />

</android.support.constraint.ConstraintLayout>

You can use percentage for ImageView width and height. For example, use ConstraintLayout and for ImageView:

<ImageView
   android:layout_width="0dp"
   android:layout_height="wrap_content"
   android:layout_constraintWidth_percent="0.7" />

I've had same problem but I've found this: https://github.com/intuit/sdp It's a library with dimensions represented by sdp. It just library with dp but scaled for different screen sizes.
