android - OnTouchListener,the code jump and, method doesnt run -

-

I have a simple code, just do not understand why my method is math kordanadas imagine (motion event e ) Do not work

The listener first called that method 

  View.OnTouchListener clickPinta = new View.OnTouchListener ( } {} @ Override Public Boolean On Touch (see V, Motion Event Event) {Log. ("Clickbint", "ontouch"); If (event.getAction () == MotionEvent.ACTION_UP) {Log.i ("ClickPint", "ACTION_UP"); // This log calculusCoordenadasImagen (event); // This method is not executed Log.i ("onToucn", "Pasa Callua Cord"); // This log works in Gardado Cordandas (Last Touch X, Last TouchView); Back true; }         return false; }};

// This is a way that is not going and I can not understand why. 

  Zero mathCondardadus Imagen (Motion event e) {log. ("CalculcaCoordenadas", ""); // This log does not work float [] M = new float [9]; Matrix.getValues ​​(m); Float transax = m [matrix. MTRANS_X] * -1; Float transwise = m [matrix. MRARNS_Y] * -1; Float scale x = m [matrix. MMSCile_X]; Float scaleY = m [Matrix.MSCALE_Y]; Last Touch X = (Int) ((E.T.TX) + Transx) / Scale X); Last Touching = (Int) ((EEGE) + Transization) / Scale-Y); Last Touch X = Math (Last Touch X); Previous Touch Y = Math }

This is the method that has an error but because the previous method does not run: 

  zero guardaCordenadas (int x, int y) {log I (" GuardaCoordenadas "," "); Marking = new mark (X, Y); ListaPtos.add (M); Log.i ("listaPtos0" "," + m.x + "-" + m.y); }

And the first lines about Logkat error:

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
