推荐答案

我怀疑这可能是与您粘贴的代码之外的内容有关的问题，但是您可以尝试以下方法作为onclicked的替代方法，该方法可能会起作用更适合您.

I suspect it may be an issue related to something outside of the code you've pasted, but you can try the following as alternatives for the onclicked which may work better for you anway.

如果以下两个选项都不起作用，那么您需要检查控制台日志中是否有可能导致它的任何原因.

If neither of the below options work then you need to check your console logs for anything that might be causing it.

onTouch: {
  if (event.isUp()) {
    //do stuff here
  }
}

或

gestureHandlers: [
    gestureHandlers: [
        TapHandler {
            onTapped: {
                 //do stuff.  This is equivalent to an onClick
            }                
        },
        LongPressHandler {
            onLongPressed: {
                //do stuff when user holds down
            }            
        }        
]
