touchscreen

问题 I am a newbie to Unity, any help will be much appreciated. I want to make a game where character (shown in below image) moves forward continuously. Character has to move upwards when user touches mobile screen (long touch will make character move upwards continuously), otherwise character falls down slowly due to gravity. Main theme is to avoid touching obstacles and character motion should be curvy. This is a 3D game, but character moves in x,y axis. Till now, I have written below code to

问题 I'm using an "adafruitts" touchscreen with a raspi to control a usb peripheral. The full raspbian kernel takes forever to boot (50 seconds), and part of that is due to the touchscreen driver loading (by modprobe/udev) and initializing. During the first 20-30 seconds of boot, the display is not loaded, so it is blank. I need this to be a user-friendly item that cannot be blank for 30 seconds each time it is turned on, so I've used buildroot to build a small kernel with the touchscreen driver

问题 I have a waveshare 3.5 inch touch LCD display and I m trying to get it working with the latest version of Raspbian A.K.A Raspbian Jessie. I followed futurice.com 's tutorial on getting it to work (tutorial is titled I'd like some LCD on my pi) and it worked on Raspbian Wheezy just fine. All I get now is a blank white screen. All help is greatly appreciated! (I must use the official Raspbian Jessie image without NOOBS from the Raspberry pi website.) I have a Raspberry Pi 2 Mobel B +. 回答1: From

问题 I wrote a simple subclass of ImageView that I want to use to detect double clicks on GridView -items: public class DoubleClickImageView extends ImageView { public interface ClickListener { void onSingleClick(); void onDoubleClick(); } private ClickListener imageClickReceiver; private GestureDetector gestureDetector; @Override public boolean onTouchEvent(MotionEvent event) { gestureDetector.onTouchEvent(event); // return super.onTouchEvent(event); does not work with gestureDetector // return

问题 I made a Javafx application that works fine on PC. Now, I try to transfer it to Android Smartphone. To do that, I use JavaFXPorts (Gluon), with Eclipse and Gradle. Now, I am stuck with a very simple example: void showPopUp() { Button button = new Button("Action do do")); HBox.setMargin(button , new Insets(10, 30, 10, 30)); button .setOnAction(e -> { actionToDo(); }); Scene scene = new Scene (button, 100, 200); Stage stage = new Stage(); stage.initModality(Modality.APPLICATION_MODAL); stage

问题 I tried all answers on this web site but None of them worked. I am using android SDK r_18 and developing an application on android 2.2 . I still don't know why examples do not work. if I add mapView.setOnTouchListener(this); to onCreate() function the at below works for one time. When the function returns false, it does not work again. public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == 1) { GeoPoint p = mapView.getProjection().fromPixels( (int) event.getX(), (int)

问题 I am working on a Blackberry application which includes Zoom pinch functionality, but this functionality works in touch screen devices. My app will work on curve type of devices too. Please let me know if "I can detect programmatically if the device is touch screen or not" so I can make my application flexible for both types. 回答1: If you only need to support OS 4.7+ devices, then you don't need to use the preprocessor. You can programmatically test for the touchscreen with this: boolean

问题 How would I go about installing a handler of touchscreen gestures in Tkinter? I need to something particularly simple: to increase the font size whenever an 'expand' gesture is detected. Is this even possible to do in Tkinter if Tcl/Tk doesn't specifically implement it? I suppose that either the window manager sends the client window some event that I could listen for and handle, or the client must register to the window manager a handler for a specific kind of event, but if it isn't possible

问题 I'm using WPF to write a windows 8 tablet application and have a ListView control on the screen. The list view has numerous rows that cover more than 1 page, so vertical scrolling is enabled. When I touch the screen a pale blue selector appears and stays in the middle of the screen as I scroll up and down (but the selected item which is highlighted in a darker blue doesn't change). I'm guessing it's the mouse over effect as the same happens effect appears when I use the mouse. I use a

问题 Can anyone point me to some code samples on how I could implement a gallery like the one in iOS where you can swipe side to side to change the image when using a touchscreen monitor on Windows 7? 回答1: You will need to implement swipe-like animations for this. Guidelines for touch in WPF apps I haven't tried this myself, but here is what seems to be an open source repo for a WPF carousel that might be worth taking a look at Blog entry about swipe animation in WPF Change the image on desired
