问题 I've seen this post with a solution to make a Spinner look like an EditText. What I want instead is the spinner to look like an ImageView (the selected Image). This way the Spinner is completely stripped of unnecessary padding and the triangle at the bottom-right. (So on the screen it's an Image, but if you click on it, it opens up like a Spinner.) PS: I already have a custom Spinner with Images as items, but I still have some padding issues and the spinner-triangle that I would like to

问题 In my app, I have a bunch of images in my drawable folder which I select at random and display using imageView.

问题 I've been trying to load an image into an ImageView , and it works fine when I run it as a standalone app, but when I try to run it in the browser or as webstart it doesn't get shown.

问题 I'm trying to build a replica of MineSweeper, to do this I'm trying to setup some premade images (100x100 pixels made in Photoshop) into an imageview and then when clicked hiding it (to reveal the number below). Without much complexity -- Just the image going visible and invisible I am finding a lot of issues and difficulties. It is likely due to a complete lack of knowledge on Javafx in general but I even following tutorials to the t I am still unable to implement this feature. I will attach

问题 How can i set a listener on an transparent ImageView that is above the map, to only react to pinching (zooming) events on it, while everything else like moving the map gets handled by the Google map? My goal is to create centered zooming on the map which can be done like so: mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(mGoogleMap.getCameraPosition().target, amountOfZoomNeeded)); but i need to catch that pinch event first, and only that event since onTouch blocks using the map

问题 I have this URL https://speakyfox-api-qa.herokuapp.com/api/v1/files/be28dcec-4912-4f58-8cb8-12b9b2948fc3 . There is a PNG image on this URL address in blob storage accessible without any headers (normally) on the REST API. It opens normally from the web browser (e.g. Chrome). However, any attempt to load it in Java Android application to ImageView fails miserably. I have tried Volley, Picasso, Glide, Retrofit and manual methods. I include some code I have tried. The closest I have got to it

问题 This problem might seem very basic but I couldn't find an answer to it. I need to place an imageView in a special position in the screen. Suppose, I need it to be three tenth from the top, and one fifth from the left of the screen. The first thing that comes to mind is to use an AbsoluteLayout and place the imageView using absolute coordinates. However this method causes problems in working with different screen sizes. The problem is that I can not get the screen dimensions (width and height)
