Question

我目前正在尝试从炼金术中发布并获取 JSON，我已经得到了，无论如何，我无法发布，有谁知道从 android 应用程序中的编辑文本中 psot 到炼金术的正确格式？有谁知道，我真的需要知道帖子的电话是什么？

public class MainActivity extends AppCompatActivity {

这取决于你在Alchemy上发布什么，以及你想做什么。 您可能应该查看并熟悉 Alchemy API 文档 (http://www.alchemyapi.com/api/calling-the-api(。 确保您拥有 Alchemy API 密钥，并且您了解特定计费计划施加的调用限制。
