Question

我想要一个3-4岁孩子的测试。我想如果他们点击不同的苹果，真正的数量必须加一。如果他们点击相同的aplles之一，则假计数必须加1。然后点击任何苹果问题和苹果必须改变。

我的朋友帮了我，我们做了很多。点击问题和答案的变化。但是当点击任何苹果错误计数加上一个时，无论它是真是假答案。

你能帮助我吗？

我们认为if命令只会出现问题。他试了很多但却无法解决问题。

非常感谢

Answer 1

您正在比较drawables。从不匹配。将你的if（CONDITION）改为以下：

if(secenek1.getDrawable().getConstantState().equals(getResources().getDrawable(dogruCevap).getConstantState())).

其他两种情况相同。
