I\'m working on an android app and I\'m fairly new to all this, including mobile app development, so I have a few questions. Any help would be amazing!
1) Is it possible
Yes swiping is possible:
OnTouchSwipeListener
import android.content.Context;
import android.view.GestureDetector;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector;
private Context context;
/* (non-Javadoc)
* @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
*/
public boolean onTouch(final View view, final MotionEvent motionEvent) {
return gestureDetector.onTouchEvent(motionEvent);
}
/**
* Gets the gesture detector.
*
* @return the gesture detector
*/
public GestureDetector getGestureDetector(){
return gestureDetector;
}
/**
* Instantiates a new on swipe touch listener.
*
* @param context
* the context
*/
public OnSwipeTouchListener(Context context) {
super();
this.context = context;
gestureDetector = new GestureDetector(context, new GestureListener());
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
/* (non-Javadoc)
* @see android.view.GestureDetector.SimpleOnGestureListener#onDown(android.view.MotionEvent)
*/
@Override
public boolean onDown(MotionEvent e) {
return true;
}
/* (non-Javadoc)
* @see android.view.GestureDetector.SimpleOnGestureListener#onFling(android.view.MotionEvent, android.view.MotionEvent, float, float)
*/
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getRawY() - e1.getRawY();
float diffX = e2.getRawX() - e1.getRawX();
if ((Math.abs(diffX) - Math.abs(diffY)) > SWIPE_THRESHOLD) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
}
} else {
if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
onSwipeBottom();
} else {
onSwipeTop();
}
}
}
} catch (Exception e) {
}
return result;
}
}
/**
* On swipe right.
*/
public void onSwipeRight() {
}
/**
* On swipe left.
*/
public void onSwipeLeft() {
}
/**
* On swipe top.
*/
public void onSwipeTop() {
}
/**
* On swipe bottom.
*/
public void onSwipeBottom() {
}
}
Implementation:
OnSwipeTouchListener onSwipeTouchListener = new OnSwipeTouchListener(Activity.this) {
@Override
public void onSwipeLeft() {
//your actions
}
};
