Best way to add dragable images onto another image in android

I was wondering what the best way to add dragable images to another image is in android. For example if I had an image of someones face how could I add an smaller image of say a comedy mouth and drag it into the correct position on the original image. Is there a nice way to go about this?
Thanks in advance

You can use FrameLayout to overlap your images.Check this out:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:id="#+id/imageView1"
android:src="#drawable/img_face"
android:scaleType="fitCenter"
android:layout_height="250px"
android:layout_width="250px"/>
<ImageView
android:id="#+id/imageView2"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:src="#drawable/comedy_face"
android:gravity="center"/>
</FrameLayout>

Android - Background at bottom

I should like to have an android app which has its background image on the bottom of the view.
Hopefully this could be achieved by only using XML.
My background image (bg.png) is located at the folder "res/drawable-mdpi".
The XML code is now:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/bg"
android:layout_alignParentBottom="true"
android:layout_marginBottom="0dip" />
</LinearLayout>
But this is stretching the whole image over the whole page. I only want it stretched in horizontal direction.
The height has to be in proportion with the (stretched) width.
And this image has to be the background of a view/layout, I want to keep using the layout and add items/objects to it.
I hope someone could help me with this, I've been looking on the internet for it for a few hours and I couldn't find anything more helpful then I have now.
Thanks in advance,
Dennis

Firstly Change your LinearLayout to a RelativeLayout (android:layout_alignParentBottom only works with RelativeLayout).
Secondly use android:src="#drawable/bg" on your ImageView (not background)

if you really want to use the LinearLayout, you can try adding this attribute to your imageview android:layout_gravity="bottom"

Android Button Layout - Not Displaying Correctly

I am trying to get three images to display on the "welcome screen" of my Android app. Only one of the images is being displayed, and I cant figure out why... any Help?
XML File:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:background="#drawable/main_bg"
>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:paddingTop="30dip"
android:layout_height="wrap_content"
android:gravity="center"
>
<ImageButton
android:id="#+id/mnwvbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dip"
android:background="#drawable/mnwvicon" />
<ImageButton
android:id="#+id/reportsbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/reportsicon" />
</LinearLayout>
<ImageButton
android:id="#+id/mnwvshowbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/showicon"
android:paddingTop="30dip" />
</LinearLayout>
I have the exact same set up in another app, so I dont know why it isnt working here??

I think its because the last image is outside the inner linearlayout so put it inside the inner linearlayout and you should be able to see all three images in a row.

Try scaling the images using the attribute android:ScaleType="centre" inside the ImageButton
or try a different layout like Tablayout for arranging the images in rows and columns with proper spacing.

Sorry guys. I didnt have the app support the different screen sizes. I am not sure why this mattered, but once I added support, then it worked perfectly!. Thanks for your input though! Anyone know why this mattered though?? I dont know why supporting screen sizes matters?

android picture frame

I'm new to android i'm developing small application i want to arrange pictures in screen just like tumbnail view and want scroll on all picture then i have to able to select the one picture after touching the picture on the screen how can i do it? plz help me
Thanks in Advance.

Well you can do that using a Gallery control to scroll the thumbnails, then when you select the picture (using the method gallery.setOnItemClickListener()) that image will be showed in the ImageView.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Gallery
android:id="#+id/gallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/image1"
android:layout_width="320px"
android:layout_height="250px"
android:scaleType="fitXY" />
</LinearLayout>
