display the word in the selected spinner in the textview

I try to explain by showing as many examples as possible, I chose a word from the spinner, for example it is "cat", after I select it in the spinner i.e. after I click it should also appear in the textview.
Spinner click "cat"
TextView change "cat"
I again click Spinner "dog"
TextView change "dog"
now my not full code:
```Spinner sababspinner = findViewById(R.id.Sababspinner);
sababspinner.setOnItemClickListener(this);
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
}```
all spinner texts in string.xml

Make an ArrayList with your spinner dataset, then in the onItemSelected method write something like textView.setText(dataset.get(position)).

findViewById not working in static function

I found error in findViewById in static function.
my function is--
public static void onYearSelect() {
Spinner yearSelector;
String yearName;
yearSelector = (Spinner) findViewById(R.id.year_submit);
yearName = yearSelector.getSelectedItem().toString();
}
is there any way to solve this error!
can i store value of Spinner in yearName as String

You need to add view inside function as parameter.
public static void onYearSelect(View view) {
Spinner yearSelector;
yearSelector = (Spinner) view.findViewById(R.id.year_submit);
yearName = yearSelector.getSelectedItem().toString();
}
The view which contains your layout data.
When you call that function add onYearSelect(rootView) here rootView have the layout view.
EDIT 1:
What is View here ?
A View in Android is a widget that displays something. Buttons, listviews, imageviews, etc. are all subclasses of View. When you say "change view" I assume you mean change the layout by using setContentView(). This usually only needs to be done once per activity. An Activity is basically what you are referring to as a screen.
You can read more here.

Set setOnItemSelectedListener on spinner object and inside onItemSelected() you can set value of yearName. Like below,
yearSelector.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
String yearName = parentView.getItemAtPosition(position).toString()
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}});

Selected item from spinner causes TextView to change automatically

I followed steps in how to change value of textview according to selected item and here is a piece of the code
public void onCreate(Bundle savedInstanceState){.......
final TextView privacyTextView = (TextView) findViewById(R.id.eventPrivacy);
privacySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View v, int position, long id3) {
final String selectedItem = parent.getItemAtPosition(position).toString();
privacyTextView.setText(selectedItem);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
list is :
<string-array name="privacy_levels">
<item>Everyone</item>
<item>Friends of Friends</item>
<item>Friends Only</item>
<item>Customize</item>
</string-array>
I have text view with value : privacy when running app it's automatically changed to Everyone -frist one on the list- so what is going wrong ?!!!

Add android:prompt in Spinner xml and set a name like
android:prompt="Privacy";
So first time it will show privacy then user can select from the drop down list.

Try this...!
final String selectedItem = parent.getSelectedItem().toString().trim();
privacyTextView.setText(selectedItem);

If you want to get first item as privacy then you need to add another item in your array as Privacy.
There is a attribute called android:spinnerMode this is used to get the spinner in two modes as dialog or dropdown.
where as the attribute android:prompt is to get the spinner Title or Heading after opening it(in Dialog mode).

Just try to this so you will get selected string:
String name = spinner.getSelectedItem().toString();

How can I know the position of the selected item of an AutoCompleteTextView in Android?

I have an AutoCompleteTextView. I set its adapter by extending a CursorAdapter.
After selecting an option from the dropdown, I like to know the position of the item, or the item, that was selected. At least, I want an id for fetching more data in Sqlite.
How can I do that?

Simply override the AutoCompleteTextView's OnItemClickedListener to find the position of the item in the dropdown list or the SQLite row id:
autoCompleteTextView.setOnItemClickedListener(new OnItemSelectedListener() {
#Override
public void onItemClicked(AdapterView<?> parent, View view, int position, long id) {
// Do whatever you want with the position or id
}
});

Automated Spinner Selection in android

I am developing an android which has 4 spinners(A,B,C,D).
What I want to achieve is
If Spinner A is set to a value I want the remaining spinners to automatically change their value depending on the value of A
Like if I set Movie(in A)--->Ticket(in B)---->Place(in C)---->Time(D) to automatically fill in.
Thanking you

I think you can set an OnItemSelectedListener to your Movie Spinner. The Spinner tutorial is an adequate example. Your OnItemSelectedListener may be like this:
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
if (parent.getItemAtPosition(pos).toString().equals("firstMovieName")) {
// set spinner B/C/D with the corresponding information of first movie
}
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}
The onItemSelected method above may be too simple for your need. You need figure it out how to link the four spinners yourself, but May it helps :)
