Solutions for handling onclick and Ontouch method conflicts in Android

Now think of the best solution, everyone has a better welcome to inform.

Problem: There is a button in a view that requires that you can move this button by tapping it, while simply clicking don't move this button to jump to the new activity.

Difficulties encountered: The movement of the button is good implementation, through the Ontouch Motionevent.action_down, Motionevent.action_move and motionevent_up can be achieved, However, if both the Ontouch and OnClick methods are implemented, conflicts can result. The theory on this aspect of the online answer is very good, below I write my solution.

The button Movement example code is as follows (transfer from Netizen):

 Public BooleanOnTouch (View V, motionevent event) {intaction=event.getaction (); LOG.I ("", "Touch:" +action); Switch(action) { CaseMotionEvent.ACTION_DOWN:lastX= (int) event.getrawx (); Lasty= (int) Event.getrawy ();  Break; /*** Layout (l,t,r,b) * L left position, relative to parent T Top position, relativ             E to parent R right position, relative to parent B Bottom position, relative to Parent * */             CaseMotionevent.action_move:intDX = (int) event.getrawx ()-Lastx; intDY = (int) Event.getrawy ()-lasty;                Move (v, dx, dy);  Break; Casemotionevent.action_up: Break; }        return false; }    Private voidMove (View V,intDxintdy) {        intleft = V.getleft () +DX; inttop = v.gettop () +dy; intright = V.getright () +DX; intBottom = V.getbottom () +dy; if(Left < 0) { left= 0; Right= left +v.getwidth (); }        if(Right >screenwidth) { Right=ScreenWidth; Left= Right-v.getwidth (); }        if(Top < 0) {Top= 0; Bottom= Top +v.getheight (); }        if(Bottom >screenheight) {Bottom=ScreenHeight; Top= Bottom-v.getheight ();        } v.layout (left, top, right, bottom); LOG.I ("", "position??" + Left + "," + Top + "," + Right + "," +bottom); }    

The core approach to solving the problem is:

Do not provide the OnClick method for this button, that is, method calls that do not add Onclicklistener,onclick are implemented in the Ontouch method.

Specific Description:

Add a Boolean global variable initialized to False (indicating that the button does not move), once the motionevent.action_move in the Ontouch is triggered, then the button is moved, the click action is not triggered, When the motionevent.action_up is triggered, no action is taken and the global variable is changed to initialize false, whereas if there is no move, then the click action is triggered.
