break cannot be used outside of a loop or a switch
提问by Kevin
String value = custom.getdob().toString();
if (value == null || value.equals("")) {
holder.item3.setText("-");
break;
}
I am actually over-riding the method getView, so i am not able to place a returnafter my if condition as it says view must be returned, but i want to exit the if condition after the check. so tried out breakand i am getting this error "break cannot be used outside of a loop or a switch"
我实际上覆盖了 getView 方法，因此我无法return在 if 条件之后放置 a ，因为它说必须返回视图，但我想在检查后退出 if 条件。所以试过了break，我收到这个错误“ break不能在循环或开关之外使用”
break; = > Throws break cannot be used outside of a loop or a switch
return; = > This method must return a result of type View
回答by Ankit
why do you even need a breakthere? its not actually required. since anyway the ifblock has finished, control will exit the block.
为什么你甚至需要break那里？它实际上并不需要。因为无论如何if块已经完成，控制将退出块。
if you wanna return the view instead of break;, put return holder;(assuming holder is a view)
如果你想返回视图而不是break;，放return holder;（假设持有人是一个视图）
break can only be used in switch & loops (for/while/do-while)
break 只能用于 switch & loops (for/while/do-while)

I think that in this particular case you can return null to exit from method.
我认为在这种特殊情况下，您可以返回 null 以退出方法。
回答by Subhrajyoti Majumder
return viewObject;you must use. Seems to be method signature is
return viewObject;你必须使用。似乎是方法签名是
public View getView(){...}
公共视图 getView(){...}
And it clearly says it should return View object or null. So you can use return null;or return the expected view object.
它清楚地表明它应该返回 View 对象或 null。因此您可以使用return null;或返回预期的视图对象。
