android应用中不响应按键事件(俗称拦截按键)

在应用中重写 dispatchKeyEvent函数：实例中为屏蔽KEYCODE_ENTER事件

public boolean dispatchKeyEvent(KeyEvent event) {

int keyCode = event.getKeyCode();
if(KeyEvent.KEYCODE_ENTER==keyCode&& event.getAction() != KeyEvent.ACTION_UP)
{
return true;
}

return super.dispatchKeyEvent(event);  


}
