I want to add an image from my library and then save it. My application crashes when I click on the setOnClickListener inside my AddImage activity. I added this code to a new project and then it worked perfectly but I don't know why it is not working in my main project.
I'm using MediaStore.
...ANSWER
Answered 2021-Apr-06 at 20:23Please check if b=findViewById(R.id.button);
belongs in activity_main.xml.
null object references result when your findViewById references an id value that is not a part of the XML defined in setContentView()
QUESTION
I am trying to make image viewer, which has overlay window with div in the center and inside the div an image that scales up and down on window resize that keeps its default ratio by using object-fit: contain; which is working ok. The problem is that when using object-fit: contain; it scales the content of the and the has someting like background layer which stops me from clicking on the overlay window so I can close the view. Is it possible to crop, cut auto resize the so it is always big as the content. Maybe using clip:rect();. Thanks in advance.
I am trying to remove the blue background so I can click on the background and close the overlay window, but still keep the ability to click on the image without closing the overlay.

...ANSWER
Answered 2021-Apr-09 at 21:18Setting the position of any object to absolute
is a little dangerous: it makes it ignore almost any relationship it has with other objects regarding position, scale etc.
As such, I would recommend using position: relative;
for your image container and allowing one of the two dimensions (I recommend using height: 100%
and width: inherit
or auto
) to scale automatically to maintain the aspect ratio. Modern browsers are smart enough to usually fill in the area given properly without leaving any gaps.
Also, remember to use margin: auto;
to center your objects nicely.
This should solve your problem:

I want to test if my byte[] element ImageData contains any data. If there is no data my database shows it as NULL. I tried using the .Any() method, but for some reason this does not work. Why?
I have tried it with the following code
...ANSWER
Answered 2021-Mar-23 at 11:07It doesn't work because you're calling a method on a null reference... In this case it's an extension method so you'll get an ArgumentNullException
instead of a NullReferenceException
, but it's behaving exactly as documented.
You can write your own extension method for this if you want:

I would like to take a photo with MediaStore.ACTION_IMAGE_CAPTURE
intent, but disable the settings button in the top-left corner. I was able to find a EXTRA_SHOW_ACTION_ICONS parameter, but it is not well documented. This is the description:

As I have pointed out previously, you do not have control over the UI of a third-party camera apps. There are hundreds of such apps; none have to give you any ability to control their UI.
What does this parameter do?
Based on a search of the Android source code, it does nothing in Android itself. If the device happens to have the AOSP Gallery app installed, it appears to control something in the image viewer there. It is certainly possible that some non-AOSP apps use that extra for some particular reason, but that behavior would vary by app.
