I am using an EditText under the Material Design and I am having problems in screen orientation. I was able to save the content onSavedInstanceState and reinstate back what was written on edittext back again but there seems to be a bug-like behavior going on.
Look at these following pics:
Original orientation when activity start:
When I rotate the screen, I still get a hold of the content but when I place the carret on an existing text span, it returns the carret to 0 (Beginning of edit text) and then when I typed something it looks like this:
I encountered this situation once and that was very long time ago. IIRC I was able to solve it by completely replacing the content onCreateView's savedInstanceState, it doesn't seem to work anymore.
Any ideas?
[EDIT] A lot of people will be expecting to answer "ONCONFIGURATIONCHANGED". No please, this is not merely the solution for the underlying problem. In fact, I tried it and didn't work, don't want to implement that solution anyways. I believe this doesn't warrant band aid solution, at least as a last resort.
Read the answer to this: Why not use always android:configChanges=“keyboardHidden|orientation”?
Here is my layout file for the 'Fragment' containing the edit text:

Next here is my Activity layout, a very simple layout actually:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/framelayout_note"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Here is create method callback for Activity:
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Log.i("NoteActivity.OnCreate" , TAG);
setContentView(R.layout.activity_note);
NoteFragment fragment = NoteFragment.createInstance();
fragment.setOnToolbarButtonSelected(this);
getSupportFragmentManager()
.beginTransaction()
.add(R.id.framelayout_note , fragment)
.commit();
}
Here is the create/onSavedInstanceState method callback for the fragment
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Log.i("NoteFragment.onCreateView", TAG);
if(savedInstanceState != null)
{
mTitle = savedInstanceState.getString(KEY_EDITTEXT_TITLE, TAG);
mContent = Html.fromHtml(savedInstanceState.getString(KEY_EDITTEXT_CONTENT, TAG));
}
mNoteDataController = ((NotifireApplication) getActivity().getApplication()).getNoteDataController();
setHasOptionsMenu(true);
setRetainInstance(true);
}
@Override
public View onCreateView(LayoutInflater inflater , ViewGroup parent, Bundle savedInstanceState)
{
Log.i("NoteFragment.onCreateView", TAG);
View view = inflater.inflate(R.layout.fragment_note, parent, false);
mNoteContent = (EditText) view.findViewById(R.id.edittext_note);
mNoteTitle = (EditText) view.findViewById(R.id.edittext_note_title);
if(mContent != null) mNoteContent.setText(mContent);
if(mTitle != null) mNoteTitle.setText(mTitle);
initToolbar(view);
return view;
}
@Override
public void onSaveInstanceState(Bundle savedInstanceState)
{
Html.toHtml(mNoteContent.getText());
savedInstanceState.putString(KEY_EDITTEXT_CONTENT, Html.toHtml(mNoteContent.getText()));
savedInstanceState.putString(KEY_EDITTEXT_TITLE, mNoteTitle.getText().toString());
super.onSaveInstanceState(savedInstanceState);
}
