Andengine----customizing Buttonsprite with text

On an article, learned the use of andengine in the Buttonsprite, said to achieve the buttonsprite with text, directly paste code:

public class Textbuttonsprite extends Rectangle {private final static String TAG = "Textbuttonsprite";

	Display text private final text mText;

	Buttonsprite Mbuttonsprite; Public Textbuttonsprite (float PX, float PY, tiledtextureregion ptiledtextureregion, Font Pfont, String ptext, Vertex
				Bufferobjectmanager Pvertexbufferobjectmanager) {super (PX, PY, Ptiledtextureregion.getwidth (), ptiledtextureregion
		. GetHeight (), Pvertexbufferobjectmanager);
		Mbuttonsprite = new Buttonsprite (0, 0, ptiledtextureregion, Pvertexbufferobjectmanager);
		MText = new Text (0, 0, Pfont, Ptext, Pvertexbufferobjectmanager);
		float buttontextureregionwidth = Ptiledtextureregion.getwidth ();
		float buttontextureregionheight = Ptiledtextureregion.getheight ();
		float textWidth = Mtext.getwidth ();
		float textHeight = Mtext.getheight (); When the length of the text is greater than the length of the button, the button is scaled to fit the text if (TextWidth > Buttontextureregionwidth | | textHeight > BUTTONTEXTUREREGIONH Eight) {Float Widthscale = TextwidTh/buttontextureregionwidth;
			float Heightscale = textheight/buttontextureregionheight;
				if (Widthscale > Heightscale) {setwidth (buttontextureregionwidth * widthscale);
				SetHeight (Buttontextureregionheight * widthscale);
			Add an offset, of course, you can not add Mbuttonsprite.setscale ((Widthscale + 0.1f));
				} else {setwidth (buttontextureregionwidth * heightscale);
				SetHeight (Buttontextureregionheight * heightscale);
			Add an offset, of course, you can not add Mbuttonsprite.setscale ((Heightscale + 0.1f));
		}} if (Mchildrenignoreupdate) {}//Calculate center position Float TEXTX = (getwidth ()-mtext.getwidth ())/2;
		float texty = (getheight ()-mtext.getheight ())/2;
		Mbuttonsprite.setposition ((GetWidth ()-buttontextureregionwidth)/2, (GetHeight ()-buttontextureregionwidth)/2);
		Mtext.setposition (TEXTX, texty);
		Attachchild (Mbuttonsprite);
	Attachchild (MText); }//===========================================================//Constants//===========================================================//===========================================================//Fields//====== =====================================================
