My question is somewhat related to my previous one, which is here ... I get the X and Y values on TouchEvent.ACTION_MOVE . It works great if I move my finger slowly, but if I quickly move my finger, it skips the X and Y coordinates, for which I used history events, but it’s still useless. I want continuous values of X and Y without any jumps.
Code example
void printSamples(MotionEvent ev, RectangleParticleEmitter ps) { final int historySize = ev.getHistorySize(); final int pointerCount = ev.getPointerCount(); for (int h = 0; h < historySize; h++) { System.out.println("At time "+ ev.getHistoricalEventTime(h)); for (int p = 0; p < pointerCount; p++) { System.out.println("****************************************"); System.out.println("Pointer Count "+pointerCount); System.out.println("Pointer "+ev.getPointerId(p)); System.out.println("Historical X "+ev.getHistoricalX(p, h)); System.out.println("Historical Y "+ev.getHistoricalY(p, h)); System.out.println("****************************************"); ps.setCenter(ev.getHistoricalX(p), ev.getHistoricalY(p)); } } System.out.printf("At time %d:", ev.getEventTime()); for (int p = 0; p < pointerCount; p++) { System.out.println("#######################################"); System.out.println("Pointer ID "+ev.getPointerId(p)); System.out.println("Pointer X "+ev.getX(p)); System.out.println("Pointer Y "+ev.getY(p)); System.out.println("#######################################"); } }
