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)).

Spinner setSelected not working properly

I have a profile activity where user select there country for the first time ,after that when user wish to change the country he will go to profile activity there he should see the previous selected country in the spinner and then he must be able to select another country from the spinner.
I am trying to update my profile activity ,I have a spinner named country in it..I am using set selected for getting the previous selected value .i am getting the value but when i am trying to change that value its not happening .
The Country_value is string
Below is the code for spinner :
country_adapter_list = new ArrayAdapter(MyProfile.this, R.layout.support_simple_spinner_dropdown_item,Country_listItems);
country = (Spinner) findViewById(R.id.sp_country);
country.setAdapter(country_adapter_list);
country.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
country.setSelection(Country_listItems.indexOf(country_value));
country_data = Country_listItems.get(position);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});

OnItemSelected() method will select the item present in list at position.
The setSelection() will internally call the onItemSelected() to set the selected item in the spinner. So calling setSelection() inside onItemselected() will not help you.

Try below code.
#Override
public void onItemSelected(AdapterView<?> **adapterView**, View view,int position, long l) {
**adapterView**.setSelection(Country_listItems.indexOf(country_value));
country_data = Country_listItems.get(position);
}

Your code is working fine, but it will not set selection on Spinner if "country_value" is not found in arraylist that you set.

recyclerview.adapter resets radio-buttons

This is my problem:
https://youtu.be/k-N5uthYhYw
and this is my onBindViewHolder() method.
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
holder.specName.setText(specList.get(position).getSpecName());
// Assign a tag number to later identify what radio-button
holder.specRadioBtn.setTag(new Integer(position));
/* Event listenr for longClick - we prob. won't use it, but it's here just in case */
holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Toast.makeText(context, "Long press", Toast.LENGTH_SHORT).show();
return false;
}
});
/* Little hack to select its Radio Button when a specific row is tapped */
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Turn rowSelectedFlag to true since the user selected this row
rowSelectedFlag = true;
// When the user taps on a row select that row's radio button
holder.specRadioBtn.setChecked(true);
// I'm not sure why, but locally the interface needs to be started by pointing it
// to where it should drive the data (to send the params)
tempInterface = new AdminUserSpecialty();
// Call the interface to send the data (row spec-name and id) back to AdminUserSpecialty
tempInterface.activateSpecSelect(specList.get(position).getSpecName().toString(),
specList.get(position).getSpecId().toString(), rowSelectedFlag);
int clickedPos = ((Integer) holder.specRadioBtn.getTag());
// Check if the radio button is already selected
if (holder.specRadioBtn.isChecked()) {
if (lastCheckedBtn != null) {
// Don't deselect if user taps on the same row several times
if (lastCheckedBtn == holder.specRadioBtn) {
// do nothing
}
// Otherwise do deselect the previously selected radio button
else {
lastCheckedBtn.setChecked(false);
}
}
lastCheckedBtn = holder.specRadioBtn;
lastCheckedPos = clickedPos;
}
// If radio is not checked set the lastCheckedBtn to null (reset counter)
else {
lastCheckedBtn = null;
}
}
});

I can't seem to preserve my radio-button selection on RecyclerView scroll. On scroll the selection becomes erratic and random. I understand that one of RecyclerView's features is to recycle rows as they leave the screen, but what do I need to do to keep my selection? Thanks much.

I know that this was answered already but if some of you are still looking for an easier answer and your application does not rely on the RecyclerView view recycling feature much (for example if you have a fixed size list of items...) you can always set your recycler view cache view size. That way it would not recycler your views hence it would not recycler the views and you will avoid copy selected values to another views...
yourRecyclerView..setItemViewCacheSize(yourItemList.size());

Save the checked / unchecked status of the radio button (you should use checkbox instead if you want to allow the user to select multiple items) to your model (i.e. your items in the list should have a field for this) when the onClick event happens. When you bind the ViewHolder, make sure you set checkbox's value to whatever you saved in your model.

It's happen because of the Recycling mechanism
(PS: its the same for the ListView or RecyclerView).
To fix that:
1) Add a booelan variable to your model to save the state of the RadioButton
2) Update your RadioButton state in onBindViewHolder() method from this boolean in the model.
3) Add setOnCheckedChangeListener() to your RadioButton to listen to his state (checked/unchecked) and to update the boolean in your model when the state changes.

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 to output text result in Android?

In an android website, I found an article about a widget similar to a drop-down list for selecting items. (Following is the link to the site; and it shows all the codes).
http://developer.android.com/resources/tutorials/views/hello-spinner.html
It uses the following code to display a message once you have selected a planet.
Toast.makeText(parent.getContext(), "Planet is Selected", Toast.LENGTH_LONG).show();
But this message "Planet is Selected" is only going to display for about 3 seconds and then it disappears. Can you please tell me how can I make the message stay on the screen for a longer time. Or how can I output the "Planet is Selected" message as a text layout in to the screen(So that it will stay on the screen permanently till I select another item from the list)? How can I use addView(tv) instead of setContentView(tv) Any help would be greatly appreciated.
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id)
{
if (parent.getItemAtPosition(pos).toString().equals("Mars"))
{ TextView tv = new TextView(HelloSpinner.this);
tv.setText(parent.getItemAtPosition(pos).toString() + "Planet is Selected");
setContentView(tv); //How can I use addView(tv); here?
//Toast.makeText(parent.getContext(), "Planet Selected", Toast.LENGTH_LONG).show();
}
}
public void onNothingSelected(AdapterView parent)
{
// Do nothing.
} }

If you want it to stay permanently on the screen, why not use a TextView and set your value to that instead of a Toast.
If you have any problems with not being able to use TextView, ie undefined. You should take a look at the textview documentation, as it is very well described there.

public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
TextView tv = new TextView(this);
tv.setText(parent.getItemAtPosition(pos).toString());
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}

third parameter Toast.LENGTH_LONG is time. so you can set any integer value ( not sure second or millisecond) ,. then on specific event call toast.hide() ;
toast is good choice for show message for some times only . so use textView if possible
create TextView with activity context :
TextView tv = new TextView(ActrivityName.this)
else if not an activity
TextView tv = new TextView(parent.getContext())
