I just started with Android Studio and I'm sure this question was maybe asked but:
I have a small app with an ImageView in the center.
Below, I have 2 buttons. All I want is this:
When one button is touched, I want the camera roll to appear, so when a photo is selected, the photo is placed inside the ImageView.
When the other button is touched, I want the user to take a photo and the photo needs to appear in the imageView.
Is there a tutorial on this specific issue?

i already read the question here
how to fire an event when someone clicks anywhere on the screen in an android app?
but it didnt work for me
thanks
I solved this problem using dispatchTouchEvent.
I have a simple soundboard which uses Buttons to represent the sounds. When a sound button is clicked. The background image is changed using the view.
Button butt = (Button)view;
butt.setBackgroundResource(buttons_on[media]);
buttons_on is a int[] representing the drawables of the buttons.
This all works perfect, but I also use a FragmentActivity to create a paged App. The App has 4 different pages which you can swipe through. When I change a button using the above code and swipe two pages to the right and than swipe back. The image of the button has changed back to it's default defined in the page.xml.
How can I prevent this behavior?
change the Buttons to ImageButtons and setting the src?
somehow prevent the page from reloading
Instead of doing that you should look at how to use a StateListDrawable. It will simplify your approach.
I am trying to get images from Internet. (i can't show my code here). i AM storing a few images in a list and displaying them in an imageview each image after tapping other.
However, I want to make a slide of these images.
It's just a basic 'move to next picture' by sliding your finger on the screen.
Same as it would be in the phone photo gallery.
It's just to navigate through the images.
At the moment the image is going to the next one by the user tapping on the screen. But in this manner we can't go to the previous image. This is why we need to change the navigation to sliding a finger on the screen.
I have used View Flipper and ViewPager but how am i suppose to add images to these views after getting from internet each time.

In my Android app I have a gallery which contains some TextViews. I realized that some users don't understand that they can scroll that gallery although the previous and next TextViews are partially visible. So I put an ImageView with a horizontal arrow under the gallery.
Now the users try to drag the arrow. Is it possible to redirect the touch event from the ImageView to the gallery so that dragging it would scroll the gallery?
Thanks in advance,
Fri
The simplest thing (if you don't mind scrolling one item at a time) is to detect the direction of the touch event on the arrow and then dispatchSetSelected(boolean selected) on the gallery... I believe that will work. after the user does that once, they will probably intuit that they can then just drag the gallery. Of course if you want to measure the touch event speed and do the calculation for how far to scroll based on that, you can do that too... but that seems like a lot of unnecessary trouble.
