Set Spinner focus to the Spinner itself after a user selection

When I turn TalkBack on, once a selection is made in my Spinner, the focus immediately goes back to the top of the screen (toolbar). I would like the focus to be on the spinner immediately after the user's selection.
I have tried setting the spinner to be focusable:
spinner.setFocusable(true);
spinner.setFocusableInTouchMode(true);
I have checked out the following StackOverflow questions and answers which do not directly address the issue I have:
How can I use onItemSelected in Android?
Adding Focus to a spinner
I am noticing that the spinner is briefly disabled as the selection is set. I am guessing this is why the focus gets delegated to a different view. How can I circumvent this disabling or work around it?
Any help would be appreciated.

I was able to fix this by performing the following (hopefully this helps someone else with the same issue):
private boolean isUserSelection; // to detect user selection
spinner.setChangeListener(this);
spinner.setFocusable(true);
spinner.setFocusableInTouchMode(true);
if (((AccessibilityManager)getActivity().getSystemService(Context.ACCESSIBILITY_SERVICE)).isEnabled())
{
spinner.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
#Override
public void onFocusChange(View v, boolean hasFocus)
{
if (hasFocus && !isUserSelection)
v.performClick(); //bypasses the caret inside the spinner so user doesn't have to tap twice to open the drop down
else if (!hasFocus && isUserSelection)
v.requestFocus();
}
});
}
In the itemSelectedListener for the spinner, use this code:
if (isUserSelection && (AccessibilityManager)getActivity().getSystemService(Context.ACCESSIBILITY_SERVICE)).isEnabled()))
durationSpinner.requestFocusFromTouch();

Where does the focus go to? Try requesting focus from there like this.
newlyFocusedView.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
newlyFocusedView.clearFocus();
spinner.requestFocus();
spinner.performClick();
}
}
});
Also try spinner.setFocusable(true);

Remove Focus change Listener of a view in android

I have added FocusChangeListener to EditText. like
etZip.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus)
{
callAreaDetailService(zipCode,false);
}
}
});
Now If I have focus on etZip and I click on Button to go to anotherActivity. etZip loses focus and show Response alert in Next Activity.
I know I can add a boolean flag for not calling service if button is clicked. But I am sure there must be an android build in method to stop focus change.
There is no function like etZip.removeFocusChangeListener . So is there any way to do this using Android SDK.

Is there a way to cancel the next field being focused on Android?

Basically, I am validating a field when the the field loses focus. When an error occurs when we check at the OnFocusChangeListener, I want it to cancel the focus and stay on the same field. Is there a way to cancel the focus on it?
public void onFocusChange(View v, boolean hasFocus)
{
if (!hasFocus)
{
if(checkError(v))
{
// Cancel focus here
}
}
}

I think requestFocus() should do the trick, see this answer for usage: https://stackoverflow.com/a/8077842/1173391
Update:
I think you are missing the check for the view id, because the onFocusChange method is implemented via interface in your class:
try setting this:
if (v.getId() == myEditText.id)
as first check on the focus change method; you have to do it for every edit-field (or use a switch instead of if) ....
OR
attach an OnFocusChangeListener to every single field:
edittext1.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
}
});

android EditText imeOption OnClick

With a Button it is simple,
<Button
android:blablabla="blabla"
...
android:onClick="doSomething" />
this will preform the doSomething(View) function.
How can we mimic this with an EditText ?
I have read about this and i read that most people use an imeOptions (which still seems necessary) and then implement a actionListener on that EditText object.
This is were i'm lost.
Is there a way to implement the "Done"-action (or send or...) from our keyboard to a onClick function like we do with a Button, or do we need to explicitly implement the listener ?
Regards !

The below code will perform some action when you press the Done key in the softkeyboard.
editText.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId==EditorInfo.IME_ACTION_DONE){
//do your actions here that you like to perform when done is pressed
//Its advised to check for empty edit text and other related
//conditions before preforming required actions
}
return false;
}
});
Hope it helps !!

I am assuming what you are wanting to do is run some code when the EditText is clicked?
If so, I have found a solution from another thread on the site:
EditText myEditText = (EditText) findViewById(R.id.myEditText);
myEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
then do this code here
}
}
});

How to validate fields after focus is changed in edittext in android

I am trying to validate my edittext field after focus is changed but it gives when the time of typing only.i.e, after entering one charecter I am used below code
fname.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s){//some validations}
But my requirement, in my form so many fields are there if we go for validation submition time its a risky one. so please help me.

Add OnFocusChangeListener to your edit text
fname.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// If view having focus.
} else {
// If view not having focus. You can validate here
}
}
});
