android – Ontouch()不适用于自定义视图？

概述我有一个类,它扩展了“View”和实现“OnTouchListener”,所以它会自动覆盖ontouch方法,但这种方法不起作用.我尝试通过在这个方法中放置断点来调试,但它没有被调用. 我试着从另一个论坛来解决这个问题.他们告诉onTouch()必须返回true;但它并不是更好. 我的课问题： public class Viewer extends View implements OnTouch 我有一个类,它扩展了“VIEw”和实现“OntouchListener”,所以它会自动覆盖ontouch方法,但这种方法不起作用.我尝试通过在这个方法中放置断点来调试,但它没有被调用.

我试着从另一个论坛来解决这个问题.他们告诉ontouch()必须返回true;但它并不是更好.

解决方法 删除实现OntouchListener并覆盖该方法：

public boolean ontouch(MotionEvent event)

更新

当然是ontouchEvent,而不是ontouch
