Question

我的代码在下面提到，并且不知道它有什么问题。我在Fragment中有列表视图，想在点击列表项上调用活动。

foreach ($keywords as $key=>$keyword){
    if(strlen($keyword) > 3){
            $where .= "keywords LIKE '%$keyword%'";
            if ($key != ($total_keywords - 1))
                $where .= " OR ";
    }
}

Answer 1

试试这个：

cListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            cListView.setItemChecked(position, true);

            Intent intent = new Intent(getActivity(), CompanyDetailActivity.class);
            getActivity().startActivity(intent);
        }
    });

Answer 2

你应该改变

 Context context = view.getContext();
 Intent intent = new Intent(context, CompanyDetailActivity.class);
 context.startActivity(intent);

到

 Intent intent = new Intent(getActivity(), CompanyDetailActivity.class);
 startActivity(intent);

Answer 3

Context的{{1}}错误，请尝试此操作。

Intent

Answer 4

试试这个：

Intent intent = new Intent(getActivity(), CompanyDetailActivity.class);
startActivity(intent);

Answer 5

更改您的代码如下

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view= inflater.inflate(R.layout.friend_fragment, container, false);
cAdapter = new FrenListAdapter(getActivity());
cListView = (ListView) view.findViewById(android.R.id.list);
cListView.setAdapter(cAdapter);
cListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        cListView.setItemChecked(position,true);
        Intent intent = new Intent(getActivity(), CompanyDetailActivity.class);
        getActivity().startActivity(intent);
    }
});
}

删除

@Override
public void onActivityCreated(Bundle savedInstanceState) {
}
