这是我的主要活动代码。以下是我的主要活动代码，它显示了四个错误：

  1. 适配器无法解析为类型
  2. 令牌“）”上的语法错误，{ 应在此令牌之后
  3. 令牌“适配器”上的语法错误，此令牌后应为 VariableDeclaratorId。

源代码：

public class HospitalParseActivity extends ListActivity {
//url where request is made
private static String url="url";

//JSON node names
private static final String TAG_NETFOX="transfer";
private static final String TAG_DATE="date";
private static final String TAG_CWEB="c_web";
private static final String TAG_CBANK="c_bank";
private static final String TAG_CCASH="c_cash";
private static final String TAG_SWEB="s_web";
private static final String TAG_SBANK="s_bank";
private static final String TAG_SCASH="s_cash";

您是否在 onCreate 函数之外编写代码？似乎 onCreate 函数在 catch 块之后的“}”处结束。您可能只想删除它
