Bring an ImageView in front of another? - android

Is there anyway to bring an ImageView in front of another in android . For example , i have a big image and how i put a small one in the top left of the big ones. Something like the small one will overlap the bigs one . thanks for helping

Wrap the images in a RelativeLayout. Place the image you want on top last in the xml, like so:
<RelativeLayout
...>
<ImageView
android:background="#drawable/backgroundimage"
... />
<ImageView
android:background="#drawable/foreground"
... />
</RelativeLayout>

Use framelayout as your root layout and then place your big image and then your small image
like this
<framelayout
......
......
......>
<ImageView
// your big image
......
.....
.....>
</ImageView>
<ImageView
// your Small image
......
.....
.....>
</ImageView>
</framelayout>

For me frameLayout is best choose ,
Than you will need just to call this line
ImageViewSmall.bringToFront();
no need even for this line , just create from code imageViews first big after small. position x y also with :
ImageViewSmall.setX( float X );
ImageViewSmall.setY( float X );

I used this to create a video "play" overlay over a thumbnail as suggested by Randy.
Here's some slightly more complete code which also makes sure the images are centered in the parent
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center">
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/ivBackground"
android:scaleType="fitCenter"
android:layout_centerInParent="true"
android:src="#drawable/downloadplaceholder"/>
<ImageView
android:layout_height="wrap_content"
android:layout_gravity="center"
android:scaleType="fitCenter"
android:layout_width="wrap_content"
android:layout_centerInParent="true"
android:id="#+id/ivPlayOverlay"
android:src="#drawable/play_button_overlay"/>
</RelativeLayout>

You can use RelativeLayout; you can test this code, I test it and it works fine:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/a_t1"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_marginLeft="10dp"
android:background="#000000" />
<ImageView
android:id="#+id/a_t2"
android:layout_width="34dp"
android:layout_height="34dp"
android:layout_gravity="top|left"
android:background="#c12fff" />

I have tried to do a similar thing with an edit text in front of a linear layout, I found that just placing the XML for the edit text after the XML for the linear layout brought it on top when the app was run. Hope this helps.

ImageView overlay not working

I have 2 layouts in my xml, a CircularImageView and a ImageView, and the ImageView must appear on top of the CircularImageView.
I've tried:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_kids_register_ll_kid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/md_white_1000"
android:orientation="horizontal">
<RelativeLayout
android:padding="16dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.mikhaellopez.circularimageview.CircularImageView
android:id="#+id/fragment_kids_row_img_kids"
android:layout_width="70dp"
android:layout_height="70dp"
android:src="#drawable/ic_boy"
/>
<ImageView
android:id="#+id/fragment_kids_row_iv_crown"
android:layout_toRightOf="#+id/fragment_kids_row_img_kids"
android:layout_marginLeft="-26dp"
android:layout_marginTop="-22dp"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/ic_crown"/>
</RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/fragment_kids_row_tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:textColor="#color/md_black_1000"
android:textSize="24sp" />
<TextView
android:id="#+id/fragment_kids_row_tv_age"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="1 ano e 4 meses"
android:textColor="#808080"
android:textSize="12sp" />
</LinearLayout>
</LinearLayout>
And it is getting cut off:
I need the image to be shown exactly at that position in the picture, but not "cropped", what I am missing here ?
BTW, this component is part of a RecyclerView row.
EDIT ---
I forgot to mention, the image is just a placeholder to show the Avatar, but the image is dinamically populated !
Thanks !
The padding (16dp) that you are applying to the first relativeLayout makes you think that there is more place and that you can move up the imageView. Actually the margin is like a gap, it doesn't extend your layout.
This is the solution I suggest , using a FrameLayout
<FrameLayout
android:layout_width="100dp"
android:layout_height="100dp">
<com.mikhaellopez.circularimageview.CircularImageView
android:id="#+id/fragment_kids_row_img_kids"
android:layout_gravity = "center"
android:layout_width="70dp"
android:layout_height="70dp"
android:src="#drawable/ic_boy"
/>
<ImageView
android:id="#+id/fragment_kids_row_iv_crown"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/ic_crown"
android:layout_gravity="right|top" />
</FrameLayout>
EDIT : You don't have to use a frameLayout, you can use a relativeLayout if you want to set different margins. The point here is really to make your containing layout bigger so you can place the imageview easily.
If you want one image to be on top of another, why you use android:layout_toRightOf?
Remove it and second image should cover first one.
Also you can try to remove margins at second image and use centerInParent, centerVertically or centerHorizontally.
Or maybe I didn't got all the problem ) then pls provide more details. Thanks.
Have you tried Using an image editor like Paint/Photoshop and merging the two images? Then you can just display one image in your view.
try using a linear layout with the orientation set to vertical.

How to position image1 on right top of the image2 in android?

How can i achieve a layout with 2 images in android, one image overlaying another image at the top right?
an image overlapping another image at the top right
http://i.imgur.com/uT3L2wl.jpg
I tried using relative layout, but i could position the overlay image by giving layout margin, but if i do that i cant support all screen sizes with that design.
and also i couldnt position the overlay image with respect to the underimage.
i want to design my layout like the pic i have shared.
I could get this working from the below code,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="#+id/c1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" >
<ImageButton
android:id="#+id/addnewcustomer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#null"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#id/c1"
android:layout_toRightOf="#id/c1" >
</RelativeLayout>
<ImageButton
android:id="#+id/hover1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/c1"
android:layout_alignLeft="#+id/c1"
android:layout_marginBottom="23dp"
android:layout_marginLeft="22dp"
android:background="#null"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
Try look at FrameLayout. It will do the job.

I want to put image over button

I want to put png image over button i tried android:background but the png takes all the button what i want exactly is to use the logo png over button like this
the info logo is my png and "about" comes from the button text
u can use this:
android:drawableTop="#drawable/SomeIcon"
so then you get this:
<Button
android:id="#+id/damage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="about"
android:drawableTop="#android:drawable/ic_menu_info_details"/>
it works for me :)
You can use a FrameLayout. In a FrameLayout, the z-index is defined by the order in which the items are added, for example
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/my_drawable"
android:scaleType="fitCenter"/>
</FrameLayout>
In this instance, the ImageView would be drawn on top of the Button, along the bottom center of the Button.
You can check this thread
Basically, you can use:
<ImageButton
android:id="#+id/ImageButton01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/album_icon"
android:background="#drawable/round_button" />
As the thread says.
Take a RelativeLayout, place ImageView inside it. Now set onClickListener on RelativeLayout.
By this way you can create more complex buttons.
<RelativeLayout android:id="#+id/your_btn_id"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
</RelativeLayout>
you can use
android:drawableTop
to put drawable at top of Button and use appropriate padding to make it position well.
<Buttton
android:layout_width="99dp"
android:layout_height="99dp"
android:background = "#drawable/bg" />
bg is your custom image.

ImageButton behind ImageView and offset

So I'm working on making a design for my app and I need to put a imagebutton directly below an imageview. But since my imageview has a border around it with a drop shadow I need to hide (shift up) maybe 10 pixels of my imagebutton behind my imageview. Here is a quick drawing of what I want.
I hope that makes sense. I've been messing around with all kinds of different arrangements but I cant get what I want. Any help would be greatly appreciated.
First of all use a RelativeLayout. Add first the ImageButton and then the ImageView, in this way the ImageView will be on top of your ImageButton. Then you should set on your ImageButton the following :
<ImageButton
....
android:layout_below="#id/ImageViewId"
android:layout_marginTop="-10px" />
Use relative layout as said. Refer
http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html
for more positions and easy design.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/Imageview"
android:layout_marginTop="-16dp" />
<ImageView
android:id="#+id/Imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="46dp"
android:adjustViewBounds="true"
android:contentDescription="#string/description_logo"
android:src="#drawable/imagename" />
</RelativeLayout>

layout with buttons in a circle?

Its a challenge for all..
How we can put buttons in relative or linear layout or any other layout in a circle same as in this image. We can do it using xml or using code. Please help.
Thanks in advance
This method is the layout equivalent of plotting arbitrary X and Y coordinates.
Features:
The child objects are automatically centered in the RelativeLayout whether you use it as the top-level layout or embed it in another.
For N images your layout contains only N+1 views.
This example layout shows how to place an ImageView in each quadrant of an XY grid with origin at the center:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:id="#+id/center"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_centerInParent="true"
android:background="#FFFF0000"
/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#FF00FF00"
android:layout_above="#id/center"
android:layout_toLeftOf="#id/center"
android:layout_marginRight="100dp"
android:layout_marginBottom="25dp"
/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#FF00FF00"
android:layout_below="#id/center"
android:layout_toLeftOf="#id/center"
android:layout_marginRight="100dp"
android:layout_marginTop="25dp"
/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#FF00FF00"
android:layout_above="#id/center"
android:layout_toRightOf="#id/center"
android:layout_marginLeft="100dp"
android:layout_marginBottom="25dp"
/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#FF00FF00"
android:layout_below="#id/center"
android:layout_toRightOf="#id/center"
android:layout_marginLeft="100dp"
android:layout_marginTop="25dp"
/>
</RelativeLayout>
I don't think this could be done with a layout different then AbsoluteLayout. How exactly it should be done, you have to try yourself, because it is kinda tricky, but possible!
This is what I had in mind and by the way not sure on 100% but with some efforts you could set it up to be proportional - to pass on different resolutions.
In case you copy&paste the code sample from the chosen answer, you are using Android Studio and it doesn't work, here is the solution: Replace #id/center with #+id/center
Hope it helps somebody. As my reputation is less than 50 I cannot add this as a comment.
