Hi Kostya, you must be the author of WiFi manager :) Nice to meet you
I am. Just wanted a little widget for myself, then it kind of went out
of control :)
The problem here is not about visual appearance, it's about EditText
behavior :) I agree that UIs should be as intuitive as possible, so I
can make you an example of what I want to implement. Imagine to have a
7x7 table of TextViews. Obviously the cells are little and the text is
ellipsized. I want that when the user taps a cell, a bigger popup
displays more information, and when the user long taps the cell, he
can directly edit the text in it. I think it's a good design but
anyway once the app is out, users will judge it :)
Ah, so it's a spreadsheet type thing. Understand.
Well, in that case, I wouldn't try to create a switchable two-in-one widget.
I'd just create an EditText somewhere in the layout, initially hidden,
and position and show it over a cell when needed, then hide (when
detecting a click on another cell).
To do this, you'd need to watch click events for all text cells, and
keep track of which one you're currently editing.
As far as positioning goes, you could add just one RelativeLayout in the
entire content hierarchy specifically for this, or (probably) use a
PopupWindow, it has an option to hide automatically when there is a
click outside of its boundaries.
I would let EditText use its default font size so it's more familiar to
the user, and position it centered over the cell.
The IME should show if you requestFocus() on the EditText, or else you
can use this:
http://developer.android.com/reference/android/view/inputmethod/InputMethodManager.html#showSoftInput(android.view.View,
int)
<http://developer.android.com/reference/android/view/inputmethod/InputMethodManager.html#showSoftInput%28android.view.View,%20int%29>

I need to know more about how focus is managed on Android platform.
Here are some questions
1. Is there ALWAYS a focused element? Or can the focus be empty?
2. How does the soft keyboard relate to the focus?

Some of the things can be done with drawable state list(s) and stuff.
The standard EditText uses a state-list drawable for its
background, it can be found under:
android-sdk\platforms\platform-X\data\drawable.
The name can be found by looking in the platform's styles.xml:
<style name="Widget.EditText">
<item name="android:focusable">true</item>
<item name="android:focusableInTouchMode">true</item>
<item name="android:clickable">true</item>
<item name="android:background">@android:drawable/edit_text</item>
<item
name="android:textAppearance">?android:attr/textAppearanceMediumInverse</item>
<item
name="android:textColor">@android:color/primary_text_light</item>
<item name="android:gravity">center_vertical</item>
</style>
So it's drawable/edit_text.xml you want.
It should be possible to create a similar background state-list
XML, to be transparent (or white without the border) for when the
EditText is not focused.
As for the rest of you requirements, including a long press to
enter editing...
I believe - as a user - that UIs should be predictable and
consistent with the platform's conventions, but maybe I'm just too
old for this mobile computing thing :)

You could still use my code but instead of using it straight,
you could just wrap it in a custom view. So instead of just a
TextView or EditView, use the above code wrapped in a custom
View and have the TextView/EditView inside it. Use the swap
code there and it would actually a bit more simple because you
could hold the data on the custom view and it would still fit
inside your layout like the existing views.
