安卓编译错误，例如 "adapter cannot be resolved to a type"

Question

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"adapter"上出现语法错误，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";

您是否在onCreate函数之外编写代码？onCreate函数似乎在catch块之后的"｝"处结束。您可能只想删除
