アプリで写真に加えて動画をアップロードする機能を追加します。これを実現するためb2に、イメージ チューザーをロードする代わりに添付ボタンをクリックshowDialog()すると、選択時にどちら (ビデオまたは写真) をアップロードするかを尋ねるアラート ダイアログがロードされ、イメージまたはビデオ セレクターがロードされます。問題は、内部クラス onActivityResult からメソッドを呼び出すと、doPositiveClick(Activity activity, int requestCode)トリガーされず、データが返されないことです。内部クラスから呼び出されていることに関係があると思いますが、それMyAlertDialogFragmentを処理する方法がわかりません。ありがとうございました。
public static final int REQUEST_CODE = 0, RESULT_PHOTO = 1, RESULT_VID = 2;
void showDialog() {
DialogFragment newFragment = MyAlertDialogFragment.newInstance(
R.string.alert_dialog_two_buttons_title);
newFragment.setTargetFragment(ChatRoomFragment.this, REQUEST_CODE);
newFragment.show(getFragmentManager(), "dialog");
}
@Override
if(requestCode == REQUEST_CODE && data.getData() != null) {
Log.v("response", "Photo Selected");
Uri _uri = data.getData();
Log.v("response", "cp1/4");
コードはここまでです^^^^ b2.setImageResource(R.drawable.picattached);
if (_uri != null) {
//User has pick an image.
Cursor cursor = getActivity().getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
//cursor.moveToFirst();
if (cursor == null){
uploadMsgPic = _uri.getPath();
Log.i("response", "cursor == null");
Log.i("response", "uploadMsgPic now = " + uploadMsgPic);
}else{
Log.i("response", "cursor = "+ cursor);
cursor.moveToFirst();
Log.v("response", "cp2/4");
//Link to the image
//cursor.moveToFirst();
