Question

我之前在片段上使用过这段代码，我想在Activity中使用这段代码，但是当getActivity（）出现错误时这是我的代码

final ListView listView = (ListView) rootView.findViewById(R.id.list);
adapter = new CustomListAdapter(getActivity(), exerciseList);
listView.setAdapter(adapter);

pDialog = new ProgressDialog(getActivity());
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();

Answer 1

getActivity()上没有Activity方法。将getActivity替换为this（或者，如果需要，TheNameOfYourActivityClass.this，其中TheNameOfYourActivityClass是您的活动类的名称。）

Answer 2

将getActivity()更改为this或ActivityName.this

Answer 3

getActivity method is not resolve in Activity.You can use getApplicationcontext.

活动中的getActivity警告
