How to create angled ribbon with textview

I'm trying to create such a list of items in android, I am able to complete almost everything except the orange ribbon on the right top corner, I tried different methods to achieve this UI element but none of them works properly for me. I tried rotating a text view by 45º with the ribbon image as background but the edges of the ribbon weren't perfect I also tried adding the ribbon as an image view and placed a text view on top of that but It was really difficult to place the ribbon and text view like this. So what is the easiest and most efficient way to achieve this?
Thanks in advance.

I don't think there is a native android component that supports such a feature. You can create a custom view making use of the path. Here is a great tutorial if you want to follow it.

Put this TextView into your FrameLayout/CardView:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ff8f00"
android:textSize="16sp"
android:text="25% Off"
android:layout_gravity="end"
android:paddingStart="30dp"
android:paddingEnd="30dp"
android:layout_marginStart="20dp"
android:layout_marginEnd="-20dp"
android:rotation="45"
/>
To achieve best look, play with padding and margin attributes.

How to create a filled screen ImageView

I want to create a activity that looks like the gallery or whatsapp image view
I want the image to got displayed in its normal size and allow users to zoom in and out inside the ImageView so he can see the details of the image (which will contain text so i need to have zooming)
Please help cause i need this fast

This library provides zooming ImageViews.

Here is another great library i use.
https://github.com/sephiroth74/ImageViewZoom
Simply use this in xml instead of regular ImageView like this:
<your_package_name.ImageViewTouch
android:id="#+id/image_hq"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:contentDescription="#string/image_hq"
android:scaleType="matrix" />

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 Image Control

I have a big problem. I want to create a control for android in which the user sees an image and over lapping this image are smaller icons/image which are positioned relative to background image.
The smaller icons can be selected.
I really do not know how to go about it.

You could do this by having a clean image as background, like this:
and then you could have TextViews within a RelativeLayout with the names for example, and on every textView you can set the attribute clickable to your method.
Something like this:
<TextView
android:id="#+id/nevada"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/Oregon"
android:layout_marginRight="50dp"
android:layout_marginTop="21dp"
android:layout_toLeftOf="#+id/Cali"
android:clickable="true"
android:onClick="showState"
android:text="#string/Nevada"
android:textColor="#color/contact_map_text_color" />
and on your activity/fragment you will have your method that will be called by the View, in the example case: "showState"
Edit: its probably not the best approach but it certainly works

How to show a picture?

I'm having a problem calling a picture to view. In my app after they click the button i want to take them to a new page where it will display a picture and under it some text. For this example say i want a pic if dog to be at the top of the page then under it say i want something like the breed and the cost of breed. Can anyone help me?

Use this XML for your page what will display the image:
<ImageView
android:id="#+id/image"
android:src="src"
/>
<TextView
android:text="image text"
android:layout_below ="#id/image"
/>
Of course, add more options to the views
Some good references:
http://developer.android.com/reference/android/widget/ImageView.html
http://developer.android.com/reference/android/widget/TextView.html
http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html

Use ImageView.
Also for other questions like this, I highly recommend reading the User Interface section of the online Android Developer's Guide.

In a layout XML, put a LinearLayout, oriented vertically, containing first an ImageView widget then a TextView widget. You can set the text using TextView#setText(String) and the image using ImageView#setDrawable(...).
This layout will be used by an activity that reads the Extra information (for example the text to show and the image URL or the image path on the SDCard) when it starts.
You should read more about Views on the Android developer's guide as advised by Shawn Lauzon.

write the above code in your .xml
<ImageView android:id="#+id/img"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="center">
</ImageView>
and add this line in your .java class
img = (ImageView) findViewById(R.id.img);
