I am trying to implement swipe left or right in my RelativeLayout. I wrote some code but could not get swipe left or right working. I am using GestureDetector this is a my source
private GestureDetector gesturedetector = null;
private RelativeLayout swipelayout;
@SuppressLint("UseValueOf")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.strada_menu_result_loadmore,
container, false);
swipelayout = (RelativeLayout) rootView.findViewById(R.id.swipelayout);
gesturedetector = new GestureDetector(new MyGestureListener());
swipelayout.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
gesturedetector.onTouchEvent(event);
return true;
}
});
return rootView;
}
public boolean dispatchTouchEvent(MotionEvent ev){
return gesturedetector.onTouchEvent(ev);
}
class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
private static final int SWIPE_MIN_DISTANCE = 150;
private static final int SWIPE_MAX_OFF_PATH = 100;
private static final int SWIPE_THRESHOLD_VELOCITY = 100;
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
float dX = e2.getX() - e1.getX();
float dY = e1.getY() - e2.getY();
if (Math.abs(dY) >= SWIPE_THRESHOLD_VELOCITY
&& Math.abs(velocityX) >= SWIPE_THRESHOLD_VELOCITY &&
Math.abs(dX) >= SWIPE_MIN_DISTANCE) {
if (dX > 0) {
Toast.makeText(getActivity(), "Right Swipe",
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getActivity(), "Left Swipe",
Toast.LENGTH_SHORT).show();
}
return true;
}
return false;
}
}
what am i doing wrong? if anyone knows solution please help me thanks
You just need an OnTouchListener, that should be all for simple answer. Take a look. I used this code in some working project, so everything should work fine. But let me know if there is something missing and doesn't work.
yourRelativeLayout.setOnTouchListener(new OnTouchListener() {
int downX, upX;
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
downX = (int) event.getX();
Log.i("event.getX()", " downX " + downX);
return true;
}
else if (event.getAction() == MotionEvent.ACTION_UP) {
upX = (int) event.getX();
Log.i("event.getX()", " upX " + upX);
if (upX - downX > 100) {
// swipe right
}
else if (downX - upX > -100) {
// swipe left
}
return true;
}
return false;
}
});
