How to place two views inside a layout in the exact same position and size ratio?

Question

I want to place those two parts inside a layout to form a loading bar.

and

The orange indicator needs to be inside the wood board, But I can't find a way to connect them in a proper way...

The final results should look like this
.

XML File:

<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">

    <ImageView
        android:id="@+id/wood_board"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <com.menwithandroid.myhookah.gui.LoadingProgressBar
       android:id="@+id/loading_indicator"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content" />

</android.support.constraint.ConstraintLayout>

How can I connect those parts properly? Thanks.

Answer 1

It is just imageview inside imageview.The following may work for you.This is the sample code or you can just drag in design section of xml file.

Try it out with a RelativeLayout something like this:

    <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center">

           <ImageView
            android:id="@+id/wood_board"
            android:gravity="center"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <com.menwithandroid.myhookah.gui.LoadingProgressBar
           android:id="@+id/loading_indicator"
            android:gravity="center"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content" />


 </RelativeLayout>

And then set the ImageView size accordingly, which would fit into the LoadingProgressBar

with constraint layouts its very easy... you can place items in the same exact position, and the use android:elevation to ensure that one component is overlays the other.

<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">

<ImageView
    android:id="@+id/wood_board"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_marginStart="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginBottom="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    android:src="@drawable/loading"
    android:elevation="2dp"/>

<ImageView
    android:id="@+id/loading_indicator"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginBottom="8dp"
    android:src="@drawable/bar"
    app:layout_constraintBottom_toBottomOf="@+id/wood_board"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="@+id/wood_board" />

Your solution will look something like this: here

Thank you all...

I used android.support.constraint.Guideline with app:layout_constraintGuide_percent to determine the location of the indicator inside the wood board by percentages (for different screen sizes compatibility).

It ends up looking like this
