Spinner does not get selected after setting adapter - android

I have two spinner in dialog. Second one is dependent on first one. I want to bind it and then select it in edit mode. All works fine but second spinner does not get selected. However it get selected when I open my dialog next time.
Here is a part of my code.
ArrayAdapter<String> myAdap1 = (ArrayAdapter<String>) spnForeignKeyTable
.getAdapter();
int spinnerPosition1 = myAdap1.getPosition(objcolumn_schema
.getForeignKeyTable());
spnForeignKeyTable.setSelection(spinnerPosition1);
// Bind Column Spinner.Second spinner
dblist = DBAdapter.getColumns(pf.getString("dbid", ""),String.valueOf(objcolumn_schema.getForeignKeyTableID()));
ArrayAdapter<String> adpf = new ArrayAdapter<String>(
column.this, android.R.layout.simple_spinner_item,
dblist);
adpf.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnForeignKeyColumn.setAdapter(adpf);
int spinnerPosition2 = adpf.getPosition(objcolumn_schema.getForeignKey());
spnForeignKeyColumn.setSelection(spinnerPosition2);

for changing selected item in second spinner when first spinner selection change you will need to set setOnItemSelectedListener for first spinner as:
spinnerPosition1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> arg0, View v,
int position, long id)
{
// change second Spinner selection here
}
public void onNothingSelected(AdapterView<?> arg0)
{
//
}
});

spinner value updation by another spinner which uses autocomplete text view not working

I have two spinners in which the first spinner uses autocomplete textview , when first spinner item is selected in normal way without using autocomplete text view the second spinner loads the corresponding value according to the first spinners selection. My issue is that when autocomplete textview is used for selecting first spinner value the second spinner is not loaded with the values according to first spinners selection. can any one please tell me a solution
public void vesselspinnerHandler(){
//Setting Class to Spinner
final ArrayAdapter<String> vesselspinnerAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, vessellist);
vesselspinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
vesselspinner.setAdapter(vesselspinnerAdapter);
vesselspinnerAdapter.notifyDataSetChanged();
final AutoCompleteTextView searchvessel=findViewById(R.id.searchvessel);
final AutoCompleteTextView selves = findViewById(R.id.selectedvessel);
ArrayAdapter adapter1 = new ArrayAdapter(selection.this,android.R.layout.simple_spinner_dropdown_item,vessellist);
selves.setAdapter(adapter1);
selves.setDropDownVerticalOffset(50);
vesselspinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
selves.setText(vesselspinner.getSelectedItem().toString());
searchvessel.setText(selves.getText().toString());
getdate();//second spinner call
return;
}

Get last selected Spinner value before change

I have a spinner and I want to get the last selected value of it when I click on the spinner (basically just before the items in the list are being shown).
How can I achieve this?
Update:
Example: There are a dynamic amount of spinners. User clicks in spinner 1 and selects a value, let's say "house". Then clicks somewhere else. Then clicks in spinner 1 again. What I now need is to return the value "house" that was previously was selected before the user selects a different value i.e. "car" in that spinner. I can not use the local storage to save that value beforehand because it's going to be a dynamic amount of spinners to be added.
And yes, I did in fact read the documentation at http://developer.android.com/guide/topics/ui/controls/spinner.html already but what I need isn't explained there.
Maybe you can declare a String array and then use it to storage the items values. Showing this in a TextView is a way to see if it works.
Something like this:
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
selection.setText(items[arg2]);
}
I already have faced a similar situation, but I don't remember exactly how I solved it. Tell me if it gives a better idea to you, I'm new participating here.
Spinner mySpinner=(Spinner) findViewById(R.id.your_spinner);
String text = mySpinner.getSelectedItem().toString();
When the user selects an item from the drop-down, the Spinner object
receives an on-item-selected event.
To define the selection event handler for a spinner, implement the
AdapterView.OnItemSelectedListener interface and the corresponding
onItemSelected() callback method. For example, here's an
implementation of the interface in an Activity:
public class SpinnerActivity extends Activity implements OnItemSelectedListener {
...
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// An item was selected. You can retrieve the selected item using
// parent.getItemAtPosition(pos)
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}
}
The AdapterView.OnItemSelectedListener requires the onItemSelected()
and onNothingSelected() callback methods.
Then you need to specify the interface implementation by calling
setOnItemSelectedListener():
Spinner spinner = (Spinner) findViewById(R.id.spinner);
spinner.setOnItemSelectedListener(this);
IN YOUR CASE:
TO se if the user clicked on the spinner, do this:
if (spin.getSelectedItemPosition() < 0) {
Spinner mySpinner=(Spinner) findViewById(R.id.your_spinner);
String text = mySpinner.getSelectedItem().toString();
}
This means user clicked the spinner, but not any items of it.
EDIT AGAIN
public class SpinnerActivity extends Activity implements OnItemSelectedListener {
> ...
>
> public void onItemSelected(AdapterView<?> parent, View view,
> int pos, long id) {
> parent.getItemAtPosition(pos) //THIS GETS YOU THAT VALUE THAT THE USER CLICKED ON DYNAMICALLY
> }
>
> public void onNothingSelected(AdapterView<?> parent) {
> // Another interface callback
> }
> }

Solution is to add a TextView widget with each added Spinner. Set the TextView to "gone" (not visible). When the spinner changes set the value to that TextView. This way you can store the last selected spinner value in the TextView. When the user clicks on the spinner and changes the value you can still access the previously selected/unselected value from the spinner through the TextView widget.
// Use this TextView to temporarily store the spinner value
final TextView hiddenTextView = new TextView(getContext());
hiddenTextView.setVisibility(View.GONE);
final Spinner spinner = new Spinner(getContext());
spinner.setPrompt(getString(R.string.email_other));
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getContext(), R.array.email_types, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
Log.d(TAG, "TextView Value before spinner change: " + hiddenTextView.getText());
String spinnerValue = String.valueOf(spinner.getSelectedItem());
hiddenTextView.setText(spinnerValue);
Log.d(TAG, "TextView Value after spinner change: " + hiddenTextView.getText());
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
return;
}
});

How to review the selected item on spinner

Here is my code for my spinner.. i want it to save to my database by using setText but theres no option for setting it into setText.. this is how i want it to save on my database spinpstat.setText(student.status);
this is how i want it to declare in my onClick(View view)
student.status = spinpstat.getText.toString(); but it gives me following error
spinpstat = (Spinner) findViewById(R.id.spinner);
ArrayAdapter adapterstat = ArrayAdapter.createFromResource(this, R.array.statuslist, android.R.layout.simple_spinner_item);
adapterstat.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinpstat.setAdapter(adapterstat);
spinpstat.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
projstat = spinpstat.getSelectedItem().toString();
spinpstat.setSelection(position);
parent.getItemAtPosition(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
this is the data i saved .. i set the spinner status in old student
but this how the data result in review of the data i saved.. my spinner instead of status is old student it set as new student which is the first value in my spinner list
any help will do.. thanks in advance..
Use Spinner.setSelection to set selected item from Spinner like:
spinpstat.setSelection(adapterstat.getPosition(student.status));
And get selected item from Spinner on onClick as:
student.status = spinpstat.getSelectedItem().toString();

Android Spinner taking time, after select value from adapter

In my application there are lot's of views(spinner, buttons, editText, textView, ImageButton etc).
After selecting one value in the spinner it not reflect the value which I selected. The old value is till there on the spinner. But when I tap on other views like editTest then spinner value automatically updated.
I think no need to mention the code because normal spinner is there which populating data from ArrayAdapter and I am doing small task after selecting value.
CODE:-
spinnerWard = (Spinner) findViewById(R.id.spinnerWard);
aAdapterWard = new ArrayAdapter<WardList>(this,
android.R.layout.simple_spinner_item, listWard);
aAdapterWard.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerWard.setAdapter(aAdapterWard);
spinnerWard.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View v,
int pos, long id) {
intWardPosition = pos;
intFinalWardId = listWard.get(pos).getId();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {}
});

how to open edit text on specific item is selected from spinner

I build a spinner in which i put element through array list and .i store the value of get selcted item from spinner in a variable,in my spinner it having 15 element,now i want to try when a specific item is selected from spinner then a dialog box is open with edit text and button then user can edit and save it in spinner.how can i do this.
my code for spinner is
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.faultid);
addItemsOnSpinner2();
addListenerOnSpinnerItemSelection();
}
public void addListenerOnSpinnerItemSelection()
{
Spinner faultSpinner = (Spinner) findViewById(R.id.spinner1);
mspinner.setOnItemSelectedListener(new
CustomOnItemSelectedListener());
}
public void addItemsOnSpinner2() {
ArrayList<String> faulttypespinner = new ArrayList<String>();
faulttypespinner.add("XL-Cross Level");
faulttypespinner.add("AL-Alignment");
faulttypespinner.add("UN-Unevenness");
faulttypespinner.add("XL-Cross Level");
faulttypespinner.add("AL-Alignment");
faulttypespinner.add("UN-Unevenness");
faulttypespinner.add("BD-Ballast Deficiency");
faulttypespinner.add("SE-Super elevation on curve");
faulttypespinner.add("LP-Loose Packing");
faulttypespinner.add("LJ-Low Joint");
faulttypespinner.add("BA-Bridge");
faulttypespinner.add("LC-Level Crossing");
faulttypespinner.add("LJ-Low Joint");
faulttypespinner.add("P and C-Point n Xing");
faulttypespinner.add("OTH-Other Defect");
faulttypespinner.add("SEJ-SEJ");
faulttypespinner.add("WEED-Weed on Cess");
ArrayAdapter<String> faultadapter = new ArrayAdapter<String>
(mConetxt,android.R.layout.simple_spinner_item, faulttypespinner);
faultadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mspinner.setAdapter(faultadapter);
}
public class CustomOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos,
long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " +
parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
}
You'll need to implement Custom Adapter, where you'll have a method something like :
public void changeItemValue(int position, String newValue){
Item itm = getItem(position);
itm.setValue(newValue);
notifyDataSetChanged();
}
When you open the dialogBox onSelectedItem, you'll have to pass an instance of your spinner adapter to a dialog and then to the listener of a dialog button, where you'll call changeItemValue method on button click.
Why u r using custom adapter,when click on spinner get the position of clicked item and show the pop up and on button click set the value to the faulttypespinner arraylist using index stored previously. then add notifydatasetchanged for adapter to update the spinner thats all.
