I have been asked to design an app that allows the user to take an image. At the top of the image there should be data such as imageNo and workOrder.
At the minute, I have two TextViews at the top of my activity, an ImageView below and then a green button at the end like so:
ImageScreenshot
When I click the green button I would like to send this full screen, textviews and image all as one file/image to a destination - like a screenshot.
Is there any libraries out there or does anyone know how I could achieve this?
Thanks!

check out this tutorial, I think it covers the basics of the question you asked. I automatically thought of this reference as I read your query.

Suppose I'm having a screen in which there are many buttons and textViews and if someone who comes through this screen while using the application tries to take a Screenshot or Screen Record, some views shouldn't be captured. Is there anyway I can do this?
Use file observer with the path to screen shot directory here is a good tutorial

After getting solution to call my splash activity only one time (Part1 Question), Now i have to set up my splash activity.
On My First Layout i want functionality like this :
Image One <--> Image Two <--> Imgage Three --> Second xml(Activity)
Also on every image their will be a page control that will indicate on which image is currently on layout(Like the attached screenshot)/ or can be any other way to show this.
That Means From Image one i can go to image two on scrolling to right(I can come back to image one on scrolling to left) From Image two i can go to Image Three on scrolling right(I can come back to image 2 from Image three if i scroll to left)But if i scroll to right from Third Image then i should get to my Second Activity and never return back on those images.
i.e
I want to have scroll view having those three images with the page controller then after we scroll down to the third/last image on further scrolling to right i want that my second activity should be loaded and the splash should never come up.
Can any one tell me any idea how this can be done.
To make splash sheet with scroll view and page control & switch to second activity when done scrolling.
I don't want animation i want it to work manually like scrolling/ or any other way to implement this.
Coding will be much appreciated.
To implement scrollable images like shown above use ViewPagerIndicator library given HERE. Its simple to integrate and will take few minutes. All you have to do is read the usage section in given link.
For switching activity on last page, simply implement onPageChangeListener described in link and check for page number.
I would like to develop a Dialog which is composed of 3 steps to guide the user when he launches the app for the first time.
The following image is an example of what I would like to achieve:
1- I would like to know how to add a mark to close the dialog at the top-right corner?
2- How can I implement the small circles at the bottom of the screen that indicates the current step? Can they be created programmatically?
3-Only to be sure, I decided to navigate between the Dialog steps using a ViewFlipper. Is this the right approach?
Thanks in advance.
I would like to know how to add a mark to close the dialog at the
upper right corner?
Don't do that. That looks like it was a straight port from an iphone app. Use the native android dialog containers/buttons.
How can I implement the small dots at the bottom of the screen that
indicates the current step?
What have you tried? There's a million ways of doing this depending on the rest of the workflow.
Only to be sure, I decided to navigate between the dialog steps using
a ViewFlipper. Is this the right approach?
Maybe. It depends what you're displaying. If you're only displaying a single image or something simple, then that might be the best approach. I would create different dialog fragments ( you are using fragments, right?) for the different steps. That way you can automatically push them to the back stack as you move through the workflow.
one of the ways to implement the "little dots on the bottom" is :
include the dots in every image you are creating.
draw one of the dots highlighted in every image
flip through the images in order of the highlighted dots. (or highlight the dots in the order you want to show your images)
but this would make your dots disappear during the images are flipped.
if you want to avoid that :
create two different image views , one acts as a container for the main image, the other as a container for the dots, place the 1st image view above the other.
create a no of images containing just a no of dots, each with one of the dots highlighted
flip through both the imageViews in synchronization
use a "flip animation" in the upper image view
use no animation, or a minimal animation for the dots.
This will produce the desired effect. Hope this helps :-)
How do I make a photo finger-zoomable on a android device? Is there a simple way, or is it complicated? But I dont want zoom buttons. I want it like a phonebrowser, when you take your fingers and drag them from each other on the phone, it will zoom in. How do I do?? I have searched everywhere. If there no way, can I just have two buttons, - and +. If I click one, the "imageview" change size?

The simplest way is to load your image on a WebView and let it do all the work
webView.loadUrl("file://...")
I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.
The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.
Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.
I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.
EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)
This page gives a good summary of the different built in layout objects. From your description a GridView or possibly a TableLayout might work. GalleryView looks to be horizontal only.
I believe GridView is what you're looking for. Here's a tutorial: http://developer.android.com/resources/tutorials/views/hello-gridview.html
You should check out the ViewPager widget, which is available in the Android compatibility package. I spent a loooong time trying to get the Gallery widget to behave properly, but finally settled on a ViewPager which returned ImageView objects instead. Works like a charm.
