我正在开发一个名为DashboardActivity的Activity，它包含两个选项卡，即SocialFragmentTab和ProfessionalFragmentTab。这两个都是Fragments here.In ProfesionalFragmentTab我有一个列表视图，由一个自定义适配器填充BaseAdapter.Inside ProfesionalFragmentTab，“Apply”按钮就在那里。点击apply buttton，打开一个包含一些信息的对话框。它还包含一个按钮“选择最新的简历”。点击此按钮我想从我的Android手机中选择简历（一个文本文件）。我在这里使用startActivityForResult（）时遇到了一些问题。 Plz检查文件。点击“选择最新简历按钮”
，我无法浏览文件FeedListProfessionalTimelineAdapter.java
public class FeedListProfessionalTimelineAdapter extends BaseAdapter {
private Context context;
private LayoutInflater inflater;
private List<FeedItemProfessionalTimeline> listProfessionalTimeline;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
private static final int PICKFILE_RESULT_CODE = 1;
public FeedListProfessionalTimelineAdapter(Context context, List<FeedItemProfessionalTimeline> listProfessionalTimeline) {
this.context = context;
this.listProfessionalTimeline = listProfessionalTimeline;
}
@Override
public int getCount() {
return listProfessionalTimeline.size();
}
@Override
public Object getItem(int position) {
return listProfessionalTimeline.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, final ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.feed_item_professional_tab_timeline, parent, false);
if (imageLoader == null)
imageLoader = AppController.getInstance().getImageLoader();

AlertDialog.Builder alertDialogBuilder;
AlertDialog alertDialog;
Toast.makeText(v.getContext(), "clicked", Toast.LENGTH_SHORT).show();
alertDialogBuilder = new AlertDialog.Builder(v.getContext()); // we are using v.getContext here because View v is a part of Fragment that is shown through BaseAdapter inside Fragment

答案 0 :(得分：0)
替换它，因为你已经在上面有上下文：
resumeBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(v.getContext(),"clicked",Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
//Context context=v.getContext();
((Activity)context).startActivityForResult(intent, PICKFILE_RESULT_CODE); }
});
}
});
