Android EditText validation AND TextView-to-EditText swaps

fork of vekexasia/android-edittext-validator

STATUS: Incomplete for XML layouts, only tested for programatic EditText creation. My App is still early in development and I'm short on time. I'm only using this library to programaticaly created views. Feel free to test and provide tips, code or other feedback.

TextView-to-EditText hides

PURPOSE: Conserve screen consumption by showing a TextView in place of the EditText until touched. This is an optional feature of the EditText-validator. It's your choice to select the DormantFormEditText instead of FormEditText. With DormantFormEditText the on-touch swapping should work automatically.

NOTE: DormantFormEditText started out wrapping both the TextView and EditText in a ViewFlapper with the intelligent animation system to show the transition in and out. However, the ViewFlapper seems to consume width with layout wrap_content - which defeats the entire purpose of my hiding the larger EditText until it is needed by the user. You can review older commits for the ViewFlapper implementation. The end result: DormantFormEditText is now using a LinearLayout and manually triggering the animations.

NOTE: the focus loss had some trouble. I provided a workaround that assumes only one control on the screen has focus at the same time. Works fine in preliminary testing. The bug may have existed in the original FormEditText library I forked from - but was not as visually obvious. Out of time to devise a solution. Help wanted! opened issue with more details: vekexasia#32

Usage - Programatically

Simple example. You are in the onCreate of an Activity - and your ViewGroup (layout) is in the variable rootViewGroup. Add a new smart swapping EditText to your rootView:

  DormantFormEditText newEditText = new com.andreabaccega.widget.DormantFormEditText(this);
  newEditText.setText("This is the text user will edit");
  # -- Note when adding to the layout you likely inflated: go into the object and pull the viewGroup that was created to hold the two items - not the DormantFormEditText you just instantiated.
  rootViewGroup.addView(newEditText.controllingViewGrouper);

Now the user touches the presented TextView and it should transition to EditText. Suggestions are to show instructions on the page and/or color or border it.
