android - How EditText Retains its value but not textview when phone orientation changes? -

-

It is so special about the editor that it can maintain the value, but Textview and some other widgets are not available To use on saved instances) method for them.

What is the magic behind the editing text that it can maintain values?

If someone can say how it works internally

& lt; ---- Update ---- & gt;

How it works internally, please point to the part of the scenario that describes this scenario.

What is the magic behind editing especially that it can maintain values? How it works internally, please point to that part of the code interpreting this scenario.

This is a selectable asset that changes the difference in the following if position is to be taken into account. 

  @override public parcelable onSaveInstanceState () {parcelable superstat = super. Onsite InstantState (); // Save the condition if we are compelled to save the boolean = mFreezesText; Int start = 0; Int end = 0; If (mText! = Null) {start = getSelectionStart (); End = getSelectionEnd (); If (start gt; = 0 || termination = gt; = 0) {// if saves a selection, then = is saved; }} ...}   
 By default,  TextView  can not be selected. Therefore,  getSelectionStart ()  and  getSelectionEnd ()  returns  -1 , there is a false value by the variable  save . To keep content on the orientation change, set the attribute to the correct.  
 Since  EditText  is selected by default,  getSelectionStart ()  and  
 note: disabled by default  
  
 Therefore the  mFreezesText  value is incorrect.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
