使用不同的值但相同的String Key分隔JSONObjects。我该如何分开它们？

Question

我正在尝试将来自相同字符串键的JSONObjects分开＆＃34; serving_description＆＃34; （这就是我认为它被称为）他们自己的列表项。有5＆＃34; serving_description＆＃34;但它们都不同。我有它显示所有5合一列表项和编辑文本。图像在底部。如何使用相同的键分隔每个值？在这种情况下，字符串键是＆＃34; serving_description＆＃34;和5个值。

Answer 1

shit.split(",");将执行它会返回String数组的技巧，您可以迭代它。
