Anyway i got it... my updated code
public class LeftFrag extends Fragment implements OnGestureListener {
private GestureDetector gDetector;
private int nWidth = 0, nHeight = 0;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.leftfrag, container, false);
TextView tv1 = (TextView)view.findViewById(R.id.text1);
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss Z");
Date date = new Date();
tv1.setText(dateFormat.format(date));
gDetector = new GestureDetector(getActivity(), this);
view.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
gDetector.onTouchEvent(event);
return true;
}
});
return view;
}
@Override
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
//return false;
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
int SWIPE_MIN_DISTANCE = 50; //120;
int SWIPE_THRESHOLD_VELOCITY = 100; //200;
String str = "Velocity vx " + velocityX + " vy " + velocityY + " sx " + e1.getX() + " sy " + e1.getY() + " ex " + e2.getX() + " ey " + e2.getY();
Log.d("onFling", str );
// TextView tv = (TextView)findViewById(R.id.text);
// tv.setText(str);
// Log.d("Velocity", "sx " + e1.getX() + " sy " + e1.getY() + " ex " + e2.getX() + " ey " + e2.getY() + " Velocity1 " + velocityX + " Velocity2 " + velocityY);
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE &&
Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//From Right to Left
Toast.makeText(getActivity(), "From Right to Left " + str, Toast.LENGTH_LONG).show();
str = "From Right to Left " + str;
View view = getView();
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(nWidth, nHeight);
view.setLayoutParams(p);
view.requestLayout();
return true;
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE &&
Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//From Left to Right
Toast.makeText(getActivity(), "From Left to Right " + str, Toast.LENGTH_LONG).show();
str = "From Left to Right " + str;
nWidth = getView().getWidth();
nHeight = getView().getHeight();
Log.e("Log", "Width = " + nWidth + " Height = " + nHeight );
View view = getView();
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
view.setLayoutParams(p);
view.requestLayout();
return true;
}
if(e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE &&
Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
Toast.makeText(getActivity(), "From Bottom to Top " + str, Toast.LENGTH_LONG).show();
str = "From Bottom to Top " + str;
//From Bottom to Top
return true;
} else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE &&
Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
//From Top to Bottom
Toast.makeText(getActivity(), "From Top to Bottom " + str, Toast.LENGTH_LONG).show();
str = "From Top to Bottom " + str;
str = str + " 1233";
return true;
}
return false;
}
@Override
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
}
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
// TODO Auto-generated method stub
return false;
}
@Override
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
}
Now fragment expanded and collapsed well
thanks
