I am working with a relative layout in Android. I want to have a glow effect when I click on a relative layout on screen. How to archive it?
From what you have posted it seems you want your layout to have two different backgrounds depending on whether it has been clicked or not.
You achieve this by setting a selector to background

I want to create a custom shaped button like this:
I'm able to achieve a similar thing by using a RelativeLayout and overlapping a rectangle and a circle. But that way, I have to add 2 onClickListaners, one for each shape.
Is there a way in android ( other than using an image, because in image the entire rectangular view will be clickable and not just the button ) to create such a design using a single XML layout file ??
you won't have to make two listener just make one listener for the RelativeLayout
Is there any way to make following Layout in Android..? If yes please suggest how to make and how to set clickListener's of overlapping areas of Views...? i.e View 2's area overlaps 1's area and View 3's area overlaps 2'sand 4's area and so on others views overlaps..? If there is any android library to make non-rectangle buttons/Views also suggest.. Thanks.
Here is one way that this may work:
Use a rectangular ImageView for each shape. Make sure each shape is clickable.
Shape images will have a transparent portion where they fit together.
Use FrameLayout or some similar layout that will allow overlapping of Views. You will have to work with how each View overlaps.
Make the transparent portions un-clickable. See this Stack Overflow question and its accepted answer regarding one way to do this. (N.B. I have not tested this.) You should be able to work it so that clicks propagate downward to an underlying ImageView when a transparent region is clicked.
An alternate way would be just to have two views (left and right) and implement a View.OnTouchListener to determine where the click occurs by looking at adjoining pixels: their color and placement.
Good luck!
In an Android app I have a background image and two buttons on it.
This is a partial screenshot:
I ask you for the best approach to click on the sinopsis button to show an overlay text, like this:
and also to click the fotos button to show an image slider, like this:
I don't want you to show me any code. I only need recommendations to know what kind of layouts or overlay views I should use to obtain the shown behaviours.
Thank you.
A simple TextView is enough. A TextView can have a background, translucent as in your case, or gradients, etc., and padding. You can fill it with Spanned Text so you could use hyperlinks, bold, colors, etc.. If you need scrolling, TextView also supports scrolling out of the box, but it'd be better to put it inside a ScrollView because the scroll will be smoother. In any case you don't need additional layouts.
You can just use a container layout (like LinearLayout. RelativeLayout, ScrollView, etc.. depending on what you want) and specify that to have a background image and then specify your drawable. You can then use TextView to display text. Don't forget though that you will have to create custom TextViews to achieve your design.
TextView can have transparent background and so, you can get the overlay effect.
I'm trying to build an Android app where I would like to display some Buttons in various places, as in the demo image attached.
The challenge here is creating the custom buttons and arranging them.
As for the custom Buttons, I guess I could achieve that using CustomViews or a simple button with a Custom Drawable as Background.
Are these the right points to start, any other ideas?
On arranging them, I have no clue how to achieve that.
As Android_Crazy and Closeratio have already said, a RelativeLayout is the most suitable option for custom placement of buttons in general. However, for the exact placement of buttons pictured in your example, a LinearLayout would work just fine.
In a LinearLayout you may place views under or above eachother (with android:orientation = "vertical", relevant for your example) or next to each other (android:orientation = "horizontal"). You can also add margin to your views to alter the horizontal position (layout_marginLeft or layout_marginRight) or the vertical position (layout_marginTop or layout_marginBottom).
As for the buttons' appearance, I always use custom background drawables, usually with a custom xml to add a different drawable for when the button is being pressed or selected.
I want to create android buttons but the look something like the one in picture.
Normal android buttons are curved and their boarder are not joined... I want my layou
Is there a way to create a layout like this?
You can turn any ImageView into a button by setting an onClickListener on it.
Edit to better answer the question: The layout you show can be created by putting a bunch of ImageViews in a horizontal LinearLayout. The LinearLayout has a blue background. The images that provide the sources for the ImageViews have a transparent background.
Buttons are just TextViews extensions. You just have to change its background with a xml drawable which has three states
