AndroidStudio MotionEvent: detect only ACTION_UP on a second view, starting ACTION_DOWN on first view

由 一个人想着一个人 提交于 2019-12-08 09:39:24
问题 Solved it by using emandt's suggestion. My personal Solution added below. I'm using Android Studio for this. I searched for solutions but couldn't find anything resembling this. I want to know on which ImageView an UP action occurs while starting the DOWN action on a different ImageView (to eventually be able to drag one image over the other and make it snap to the same position by getting the position of the image I dragged over). My example has two ImageViews with the id imageView (left)

Android/Processing MotionEvent getX() raises exception

问题 I'm new to android development so bear with me. I've written a processing script that works with two simultaneous presses. To do this I'm using android.view.motionevent. In my main script (pde) I have this: public boolean surfaceTouchEvent(MotionEvent event) { if (event.getActionMasked() == MotionEvent.ACTION_DOWN) { //do action down stuff... } //etc do other actions... This works fine. The problem comes in handling the ACTION_MOVE: //ACTION_MOVE else if (event.getActionMasked() ==

Zoomable SVG with clickable areas - Android

问题 I'm making very simple application. It needs to show one SVG containing generalised world map. By clicking on city's name (svg rectangle), I need to show another SVG that corresponds to that city. Also, all SVGs must support zooming and panning. I managed to make SVGs support zooming and panning and that works perfect. For that purpose, I'm using svg-android library for rendering SVGs and customized TouchImageView for panning, zooming and capturing scale and touch events. But, it seems to be

Rotation of layout changes the co-ordinate of the motion event

i am cropping a image by the help of a child relative layout and i am moving it by motion event over a parent relative layout(containing image-view to be cropped). ..but when i rotate parent layout (in which i have the image view ) by 90 deg. the behavior of motion event co-ordinate changes,and does not work(drag and zoom of child layout)properly.. please somebody tell me how to fix this..i have done some research and found about the AXIS_ORIENTATION in motionevent class but did not get any example regarding to it. thanks in advance :) 来源： https://stackoverflow.com/questions/28766334/rotation

Simulate smooth Drag Event programmatically

问题 I used custom DragLinearLayout. All child I added using addDragView() are draggable (user interaction). I want to simulate Drag Event for clicked View (smooth move to the bottom of Layout). ACTION_DOWN -> ACTION_MOVE -> ACTION_UP I tried this code, but it didn't work. long downTime = SystemClock.uptimeMillis(); long eventTime = SystemClock.uptimeMillis(); float x = view.getLeft(); float y = view.getTop(); int metaState = 0; MotionEvent downEvent = MotionEvent.obtain( downTime, eventTime +

How to detect Swipe and Tap in onTouch method? I want one of two actions to be executed when I swipe and other when I just tap. Need to know how to dell the difference between tap and swipe. Here is my code: @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_MOVE) { mGestureDetector.onTouchEvent(event); } switch(event.getAction()) { case MotionEvent.ACTION_DOWN: x1 = event.getX(); y1 = event.getY(); break; case MotionEvent.ACTION_UP: x2 = event.getX(); y2 = event.getY(); float deltaX = x2 - x1; float deltaY = y2 - y1; if (Math.abs(deltaX)

Movement of simultaneous two bitmap on a view with MotionEvent

由 ぐ巨炮叔叔 提交于 2019-12-04 02:01:28
问题 I created two bitmap on my view using the following class (Simple 2D Graphics in android) and wandering to achieve that bitmap can move independently. I am calling motionevent method for this. Current issue, i do not understand why does only one object is moving right in the following code. e.g. with this code, only "not" bitmap is moved, i would like to move both bitmaps independently of eachother. scenrio: i can use my two fingures, one for each object, to move the bitmaps independently.
