Creating such a Button with Android? (Inspired by iOS)

On an iOS App I saw such a Button:
The same I would like to do in Android, how could I achieve this?
What I tried is the following code:
<Button
android:id="#+id/widget41"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:text="Email1 testmail#gmail.com"
android:textStyle="bold" />
Looks something like that:
Well just a normal (ugly looking) Button. I have no idea, how I could style it like in iOS. Any suggestions or links would be appreciated!

The best solution would be to create your own custom view that behaves like the iOS counterpart (though, as other users have mentioned, Android does have it's own design guidelines, and the view that you are seeing is an iOS implementation that is designed for that platform).
If you look at the iOS image above (a copy of yours with some parts highlighted), I have split it up into sections.
You could use an Android ViewGroup like a LinearLayout to create the overall image, and give the LinearLayout a border or background (which can be a bitmap image of a rounded rectangle for example (See Android Nine Patch for an example of how to make this fit multiple screens).
Firstly, for the mail icon you would need a LeftAligned ImageView
with appropriate dimensions.
Next up we have a Bold TextView containing the text "Email1".
This is followed by another TextView which is blue and uses the
elipsize property (as defined in an Android XML layout) to create
"..." at the end once the text has reached the max width it can
consume. (Use android:ellipsize="end" in the XML)
Finally we have an indicator image, which again can be an ImageView
sized appropriately.
You could also achieve this with a RelativeLayout, which would allow you to RightAlign the indicator image, LeftAlign the mail icon, and allow the text to fill the space in between that it can get hold of.
Example of Nine Patch use for the background here

That is UITableView in iOS(just like ListView in android). It depends on the list item design you do it. There is no such Button Control in Android.

You should design your own button to looks like iOS one.
Android has it own design guidelines:
http://developer.android.com/design/patterns/pure-android.html

Well, as others have clearly mentioned there is no default Button in Android like this, and for your info neither is in iOS. Its all about the design. Anything is possible, in the end it all comes to how far are you willing to go to achieve it.
Below is a simple code, that will be close to your design.
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:background="#drawable/text_background"
android:drawableLeft="#drawable/envelope"
android:drawablePadding="10dp"
android:drawableRight="#drawable/right_arrow"
android:ellipsize="end"
android:gravity="center_vertical"
android:text="#string/email" />
There can be other ways also, like that whole view could be a ViewGroup, either a LinearLayout or a RelativeLayout and there could be multiple TextViews and ImageViews inside that.

Here is a tutorial for creating stylized android buttons. You can round the corners and change the background colors to look like the buttons in ios.
Here is a similar question.
Hope this helps.

Android: Adding text below an image

I am trying to have an image be fitted, and have a layout below it with some black background and whit text. My problem is that the layout ends up leaving space between the image and the text itself, and I don't understand why:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitStart" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="15dp"
android:layout_below="#+id/image" >
<TextView
style="#style/text_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Couple more elements -->
</RelativeLayout>
</RelativeLayout>
I would want this second RelativeLayout of 15dp touch the bottom of the image, but unless I change the image height to something small, it leaves some space. This layout specifies how to display an image + some text below it, but I have a total of 4 images that use this layout to get loaded on the screen, in a 2x2 display. (Each image takes 25% of the screen).
Any idea how to make the RelativeLayout align exactly with the bottom of the image please?

I do not fully understand your question though I think you might have a look at the launcher layout for my Newspaper Puzzles app...
http://code.google.com/p/newspaper-puzzles/source/browse/np/res/layout/launcher_layout.xml
or perhaps from the Open Sudoku Game look at the number pad layout found here:
http://code.google.com/p/newspaper-puzzles/source/browse/np/res/layout/s_im_numpad.xml
Use the ADT tools to get the right layout is probably best if possible but I know sometimes it is difficult to use to get specific results I still recommend using the xml tools included in the Android Development Tools.

I would recomend using a compound drawable if you're trying to put text directly below an ImageView.
See the following question for more details: How do I use a compound drawable instead of a LinearLayout that contains an ImageView and a TextView

How can I get an image button's dimensions to make sense in android?

First of all, can I just say, I find laying out android UI's to be a frustrating experience? I used to think the XML layouts were simple and clean and awesome but every time I try to make anything with it I spend hours trying to do the simplest things!
In this particular instance I'm trying to make a simple horizontal bar that contains an image button of fixed size on the right and to the left of it I want an ImageView that takes up the rest of the available width. I see similar constructs all the time in the UI: the search box that appears at the top of the screen when searching, the text area and send button for composing text/googletalk messages, etc.
I've tried both a horizontal linear layout and a relative layout, and I can't get the button to look right in either one. My latest attempt has the following layout code:
It looks like this:
Using the hiearchyviewer indicates that both the imageview and the button have the same height (45px). And it shows the view dimensions and positions to be exactly what I'm looking for. Same height (differing widths of course since the ImageView is much wider). And they butt right up next to each other, centered in the Relative Layout. However the button as drawn on screen is obviously not taking up the full ImageButton view. I'm thinking it's something weird about the android system 9patch drawable used for the ImageButton background. But what do I know? I can't get it to look right no matter what I try.

How did you set up your RelativeLayout? Try to set it up like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageButton android:layout_width="wrap_content" android:src="#drawable/icon" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:id="#+id/imgButton"></ImageButton>
<ImageView android:id="#+id/imageView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:src="#drawable/red_button" android:scaleType="fitXY" android:layout_alignBottom="#+id/imgButton" android:layout_alignTop="#+id/imgButton" android:layout_toLeftOf="#+id/imgButton"></ImageView>
</RelativeLayout>
Hope this helps.

If dimensions are exactly how you are looking for , then in ImageButton and ImageView , use android:scaleType="fitXY" and check.
For simple case , I might use linearlayout with horizontal orientation with two buttons in it with proper weights.

Drawing a board (checkers) for an Android App

I am an Android Newbie trying to use my VB experience (8yrs ago) and design a UI. I am trying to create a checkers board which in VB would be a form on which I add multiple resizable panel widgets contiguously as needed in multiple rows. Since these are panels I can either add a small image (coin) on it (with the panel as background) or even add another small panel with a color that I can make visible and invisible to represent the coins. I know describing a VB UI is bad but VB is meant to make form designs easy and it really does and that is the only language I can think in for UI.
I notice that android SDK does not nearly have enough widgets for me to use. The best I could think of is using a TableLayout with multiple rows. The thing I don't get is what do I use to represent a square? Is there something analogous to a VB panel widget? I don't want to use an image because I want the board to be auto adjust to the screen dimensions.
Could some one help me with some hints?

You could define the layout in XML using a horizontal LinearLayout and fill it with 8 ImageViews (or any other container that can show an image/color) and copy it 7 times in a vertical LinearLayout, similar to this:
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<ImageView android:id="#+id/square_1"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
<!-- Set image or background here --> />
<!-- Repeat the ImageView 7 times and change the id for every ImageView
you create -->
</LinearLayout>
<!-- Reapeat the LinearLayout 7 times too -->
</LinearLayout>
This will create 8 rows with 8 squares in each and all the squares will have the same size thanks to the weight property which indicates that they should all get equal space.
To use Java code to change image/background, you will have to use:
ImageView square_1 = (ImageView)findViewById(R.id.square_1);
square_1.setBackground(Color.yellow);

Hope this helps you along the way!

How to display the image inside the android widget background?

I have a widget layout xml which sets the src to the delivered android widget 4x1 frame image.Here is the widget layout code.
<?xml version="1.0" encoding="utf-8" ?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tuwidget" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="#+id/tuwidget_img_btn"
android:src="#drawable/widgetinitial"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</AbsoluteLayout>
#drawable/widgetinitial holds the widgetinitial.png image example 4x1 at developer.android.com (AppWidget design guidelines).(4x1_Widget_Frame_Portrait.psd) What I am trying to do is display an image inside the delivered frame instead what happens is the frame image goes away and only the image I am trying to display shows up. How can I display the image inside the bounding box or the background?
Any help is much appreciated.
Another question - I think I saw in a couple of forums AbsoluteLayout is a deprecated feature for Android 2.1 and above. Is that correct? and does using AbsoluteLayout throws any force close or other exceptions?

AbsoluteLayout is deprecated. It doesn't throw any exceptions, but its generally a bad idea to use it because it is really hard to design a layout that will work on all screen sizes. There is generally a better way to do it using a different layout.
In your case, I don't follow exactly, but it sounds like you want to layer two widgets on top of each other? An image with a frame? To do so, I'd use a FrameLayout. This is designed for having multiple layers of images.
Common layout objects is also a good guide to the basic layout types.
