Overlay Two Images in Android to Set an Imageview

overlay two images in android to set an imageview

You can skip the complex Canvas manipulation and do this entirely with Drawables, using LayerDrawable. You have one of two choices: You can either define it in XML then simply set the image, or you can configure a LayerDrawable dynamically in code.

Solution #1 (via XML):

Create a new Drawable XML file, let's call it layer.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/t" />
    <item android:drawable="@drawable/tt" />
</layer-list>

Now set the image using that Drawable:

testimage.setImageDrawable(getResources().getDrawable(R.layout.layer));

Solution #2 (dynamic):

Resources r = getResources();
Drawable[] layers = new Drawable[2];
layers[0] = r.getDrawable(R.drawable.t);
layers[1] = r.getDrawable(R.drawable.tt);
LayerDrawable layerDrawable = new LayerDrawable(layers);
testimage.setImageDrawable(layerDrawable);

(I haven't tested this code so there may be a mistake, but this general outline should work.)

How to overlay image in layout in android

Use FrameLayout :

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imgFirst"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"/>

    <ImageView
        android:id="@+id/imgSecond"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center"
        android:src="@drawable/ic_launcher"/>
</FrameLayout>

Glide overlay two image urls into the same imageView

You cannot directly display two images in a single imageView without using a custom view.

If you want to use Glide and achieve similar functionality, place another ImageView just above your ImageView (By wrapping them in a FrameLayout or a RelativeLayout).

Then load overlay image in the ImageView at the top and set its alpha to 0.5 or any desired value.

how to half overlap imageview on another imageview in android

Simply you can use RealtiveLayout and negative margins

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_landing"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/screen_background">


    <ImageView
        android:background="@color/black"
        android:id="@+id/img_background"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher" />

    <ImageView
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_below="@+id/img_background"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="-40dp"<!-- negative margin to half of height -->
        android:src="@mipmap/ic_launcher" />

</RelativeLayout>

How to overlay 2 imageviews specifying the position

You can use FrameLayout to stack views on each other.

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ImageView 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:src="@drawable/img_green" />
    <ImageView 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:src="@drawable/img_red"/>
</FrameLayout>

then you may set android:layout_margin="" to properly position the ImageViews.

Note that the last child of FrameLayout is the top most visible view

overlay canvas image with another image android

What about adding the second image over the first one?

@Override
protected void onDraw(Canvas canvas)
{
    super.onDraw(canvas);
    Bitmap temp = BitmapFactory.decodeResource(getResources(), R.drawable.floorplan);
    image = Bitmap.createScaledBitmap(temp, canvas.getWidth(), canvas.getHeight(), true);
    canvas.drawBitmap(image, 0, 0, null);

    Bitmap over = BitmapFactory.decodeResource(getResources(), R.drawable.overlay);
    image = Bitmap.createScaledBitmap(over, canvas.getWidth(), canvas.getHeight(), true);
    canvas.drawBitmap(image, 0, 0, null);
}
