I've a TextView that shows a background image.
I need to show or hide this image depending at a condition (if x=1 show image, else hide image).
I'm using the code:
t1.setBackgroundResource(R.drawable.ficha);
And it shows the image.
But I don't know how to hide it.
t1.setBackgroundDrawable(null);
The Reuben Scratton's answer is correct but deprecated in the new API versions. Another solution is:
t1.setBackgroundResource(0);

I have an image which include 10 boxes on my image view. When I click the one of boxes I want to change color of box (fill with color). How do I do that? Should I use Surface View or something else?
Update:
I found a solution. But if I use AsyncTask the code does not work. If I use a normal class the code works. I do not know why but I think problem is related with invalidate().

So the simplest thing to do would be to create a Compound Control. This compound control would essentially be a LinearLayout with both and ImageView and a TextView in it. Then, where ever you use a CarouselImageView in your code, just use your new compound control instead.
I want to show numbers over icons in my application. These numbers will come at the runtime. As shown in the image. Please help, how i can achieve this in android.
ICON image
Make a FrameLayout with your ImageView, then make another imageView with the red cicle and a TextView for the number.
Then you can make this badge very easy. just play around with the layout.
In a Framelayout every Item is over another item.

Anyone know any property of android to directly set select dark shadow

Please anyone suggest how its possible ?

you can use setAlpha method of imageView class to do this.
imgView.setAlpha(90);

Thats the link for adding images to show different state of buttons. You create a xml file for this and set this file as the background for the button.
I am new to Android/Java/Programming...
I am not sure if I am researching the correct term, but I am looking to have a horizontal bar on my application with no animation. The bar will show a static number from x to y based on a selected button from the user.
Can a ProgressBar be used as a standalone graphic like a bar graph? What is the correct term for me to research?
Edited to add…
Can I remove the user functionality from being able to adjust the seekbar?
The progress bar is used to show progress of some operation and it used the concept of threading.
In your case I think you are talking about seekbar ,.. the value of seekbar can be changed in the application through appropriate controls..e.g onbuttonpress or editing value in textbox
hi what you are looking for is actually a seek bar...
Go through this for a sample
I think you are looking for SeekBar.
A SeekBar is an extension of ProgressBar that adds a draggable thumb. The user can touch the thumb and drag left or right to set the current progress level or use the arrow keys.

Hope this will solve your issue.
