To implement Swipe Gesture we have to implement the on touch method for a particular widget
class LayoutTouchListener implements OnTouchListener{
@Override
public boolean onTouch(View v, MotionEvent event) {
gestureDetector.onTouchEvent(event);
return true;
}
}
mBaseLayout.setOnTouchListener(new LayoutTouchListener());
Then implement the SimpleOnGestureListener and do whatever you wish
SimpleOnGestureListener simpleOnGestureListener
= new SimpleOnGestureListener(){
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
String swipe = "";
float sensitvity = 50;
// TODO Auto-generated method stub
if((e1.getX() - e2.getX()) > sensitvity){
swipe += "Swipe Left\n";
}else if((e2.getX() - e1.getX()) > sensitvity){
swipe += "Swipe Right\n";
}else{
swipe += "\n";
}
if((e1.getY() - e2.getY()) > sensitvity){
swipe += "Swipe Up\n";
}else if((e2.getY() - e1.getY()) > sensitvity){
swipe += "Swipe Down\n";
}else{
swipe += "\n";
}
gestureEvent.setText(swipe);
return super.onFling(e1, e2, velocityX, velocityY);
}
};
GestureDetector gestureDetector
= new GestureDetector(simpleOnGestureListener);
