我刚刚为我构建的 Android 应用程序创建了我的第一个库（我有我需要在未来跨不同应用程序重用的代码）并且我需要从库中启动我在主项目中拥有的方法 - 但是当我尝试使用以下行来做到这一点：
com.project.sample.datasettings.UpdateActivity.success();
我收到一个编译器错误，说明：
com.project.sample.UpdateActivity Cannot Be Resolved To A Type

return stream;
}
protected void onPostExecute(InputStream queryResults) {
// TODO Auto-generated method stub
super.onPostExecute(queryResults);
com.project.sample.datasettings.UpdateActivity.success();

}
更新活动代码示例：
public void success() {
// to parse the response
try {
handler.getQueryResponse(stream);
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// to set method to save the ArryaLists from the parser
setArrayList();
Intent i = new Intent(this, ConfigFinalActivity.class);
startActivity(i);
