我的问题是这样的：当我打开对话框片段，我送的境界和境界结果从活动对话片段。 我总是发送不同的境界结果对话框片段，这取决于我点击活动。 这是在对话片段代码，我收到的境界和活动，当我点击打开的对话框片段realmResults：
public void setChangeNoteListener(ChangeNoteListener mChangeNoteListener, RealmResults<Drop> realmResults, Realm realm) {
mNotelistener = mChangeNoteListener;
mRealmResolts = realmResults;
mRealm = realm;
}
之后，我接受他们，我用它们来显示对话框片段的一些数据。
问题是，当我更改应用方向，应用程序获得粉碎，因为我不能使用境界的结果了。 我的问题是，如何保存与onSaveInstanceStat当应用方向改变整个王国的结果，再次使用该领域的结果。
请注意，在境界的结果不仅是一个项目，还有更多项目。
编辑：我拯救境界日期
@Override
public void onSaveInstanceState(Bundle outState) {
Bundle argumetns = getArguments();
int position = argumetns.getInt("POSITION");
outState.putString("myTitle", String.valueOf(mRealmResolts.get(position).getWhat()));
outState.putString("myNote", String.valueOf(mRealmResolts.get(position).getWhat_note()));
super.onSaveInstanceState(outState);
}
当我加载应用程序我加载的应用程序是这样的：
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mBtnClose = (ImageButton) view.findViewById(R.id.btn_close_note);
mBtnDelete = (ImageButton) view.findViewById(R.id.dialog_btn_delete_note);
mEditTextTitle = (EditText) view.findViewById(R.id.dialog_text_naslov);
mEditTextNote = (EditText) view.findViewById(R.id.dialog_text_note);
mBtnEdit = (Button) view.findViewById(R.id.dialog_btn_edit);
mBtnCompleted = (Button) view.findViewById(R.id.dialog_btn_completed);
mBtnSave = (Button) view.findViewById(R.id.dialog_btn_save);
mBtnForward = (ImageButton) view.findViewById(R.id.dialog_btn_forward);
mBucketNoteTime = (BucketPickerView) view.findViewById(R.id.bpv_date_in_note);
mBucketNoteTimeNonSelected = (BucketPickerView_Unselected) view.findViewById(R.id.bpv_date_in_note_unselected);
mSwitchButton = (Switch) view.findViewById(R.id.switchButtonNote);
mSwitchChangeDate = (Switch) view.findViewById(R.id.switchChangeDate);
mSwitchNoteText = (TextView) view.findViewById(R.id.switchTextAbboveNote);
dialogPickerButtonNote = (ImageView) view.findViewById(R.id.dialog_picker_button_note);
mBtnClose.setOnClickListener(this);
mBtnDelete.setOnClickListener(this);
mBtnEdit.setOnClickListener(this);
mBtnCompleted.setOnClickListener(this);
mBtnSave.setOnClickListener(this);
mBtnForward.setOnClickListener(this);
dialogPickerButtonNote.setOnClickListener(this);
if (savedInstanceState != null) {
Log.d("realmtest", "onViewCreated: prvi");
String mojStringTitle = savedInstanceState.getString("myTitle");
String mojStringNote = savedInstanceState.getString("myNote");
mEditTextTitle.setText(mojStringTitle);
mEditTextNote.setText(mojStringNote);
buttonWhenSaveVisibility();
setTitleNoteTextToDialogNote();
}
else {
buttonWhenSaveVisibility();
setTitleNoteTextToDialogNote();
}
}
当我上旋转这行代码（当我试图从境界得到的数据）screan和和呼叫方法setTitleNoteTextToDialogNote（）应用程序获得粉碎。
mEditTextTitle.setText(mRealmResolts.get(position).getWhat());
下面是错误：
