Question

我在 class 下面创建，但数字变为空。相同的代码在 activity 上运行良好。我在 Fragment 的上下文中进行了更改。还有什么在代码中造成问题。

public class TestFrag extends Fragment {
    private static final String[] phoneProjection = new String[]{ContactsContract.CommonDataKinds.Phone.DATA};
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.testfrag, container, false);

        TextView textView = (TextView) view.findViewById(R.id.clickme);
        EditText editText = (EditText) view.findViewById(R.id.contact);

        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
                getActivity().startActivityForResult(intent, 1);

            }
        });


        return view;
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {

            case (1):


                //ContentResolver cr = getContentResolver();
                Uri contactData = data.getData();
                Cursor c = getActivity().getContentResolver().query(contactData, phoneProjection, null, null, null);
                if (c.moveToFirst()) {
                    String numbers = c.getString(0);
                    Log.e("Hi", numbers);

                }
                break;
        }
    }
}

您正在调用 getActivity().startActivityForResult(intent, 1); 它的响应将在 activity 的 onActivityResult() 方法中处理您应该调用 startActivityForResult(intent, 1); 这是片段的方法并将调用片段 onActivityResult().
