我不知道我做错了什么 - 但是在结合我拥有的两个不同文件的源代码后，我在编译以下代码时遇到了几个问题。任何关于可能导致这些问题的建议（作为一种学习经验）以及解决这些问题的方法是否不太复杂，我们都将不胜感激。

（提前致谢！）

我认为您在 AsyncTask 结束时忘记了一个“}”（在 onCreate 之前）

据我所知，这是您的问题：

  1. 你每个人最后都nameValuePairs.add(new BasicNameValuePair(.. , ..);需要一个额外)的。
  2. 你缺少 a}来结束你的范围，AsyncTask我实际上认为你缺少 2 来结束你的内部类（否则你有重复的onCreate方法）
  3. 你的MyAsyncTask班级有一个public修饰符。去掉它。
  4. 你的doInBackground方法应该返回一个Double不是Object
  5. 你AsyncTask现在被称为AddEditCountry与你的外部类相同。这是不可能的。更改其中一个名称。
  6. 您的AsyncTask类是在您的onClick(View v)方法中定义的。将类移出方法。¨
  7. 您不能使用thisinbtn.setOnClickListener(this);因为点击侦听器需要是一个OnClickListener，而您的类不是。您可以通过创建一个OnClickListener实现您的 onClick 方法并将其作为参数传递的新方法来解决此问题。（就像您使用保存按钮所做的那样）

我不明白为什么你有一个内部 Activity 类。我建议您重新考虑您是否真的想要这种内部活动，或者您只是想要其中的方法/功能DeviceConfig，AddEditCountry或者它们应该位于两个不同的文件中。
