The technique here is to extends ViewPager and mimic most of what the pager will be doing internally, coupled with scrolling logic from the Gallery widget. The general idea is to monitor the fling (and velocity and accompanying scrolls) and then feed them in as fake drag events to the underlying ViewPager. If you do … Read more
This is what I’ve made public class CustomListCell extends ListCell<Document>{ private double lastYposition = 0; public CustomListCell(){ setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { lastYposition = event.getSceneY(); } }); setOnMouseDragged(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { double newYposition = event.getSceneY(); double diff = newYposition – lastYposition; lastYposition = newYposition; CustomScrollEvent cse … Read more
// Obtain MotionEvent object long downTime = SystemClock.uptimeMillis(); long eventTime = SystemClock.uptimeMillis() + 100; float x = 0.0f; float y = 0.0f; // List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState() int metaState = 0; MotionEvent motionEvent = MotionEvent.obtain( downTime, eventTime, MotionEvent.ACTION_UP, x, y, metaState ); // Dispatch touch event to view view.dispatchTouchEvent(motionEvent);
By definition, a swipe gesture is necessarily also a pan gesture — both involve translational movement of touch points. The difference is in the recognizer semantics: a pan recognizer looks for the beginning of translational movement and continues to report movement in any direction over time, while a swipe recognizer makes an instantaneous decision as … Read more
Here’s the simpliest working version of flinger I can think of. You can actually tie it to any component, not only ImageView. public class MyActivity extends Activity { private void onCreate() { final GestureDetector gdt = new GestureDetector(new GestureListener()); final ImageView imageView = (ImageView) findViewById(R.id.image_view); imageView.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(final View view, final … Read more
