how can get spinner values when I used if else then pass value to setonClick?

how can get spinner values when I used if else then pass value to setonClick?
in my code, I used this methods to set spinner values
DatabaseReference chk_sub = FirebaseDatabase.getInstance()......
chk_sub.addValueEventListener(new ValueEventListener() {
if(xxxxxx){
List<String> sub = new ArrayList<>();
sub.add(0, getApplicationContext().getResources().getString(R.string.choose_sub));
sub.add("USA");
sub.add("CA");
ArrayAdapter<String> dataSpinnerAdapter;
dataSpinnerAdapter = new ArrayAdapter(getApplication(), android.R.layout.simple_spinner_item, sub);
dataSpinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(dataSpinnerAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if(parent.getItemAtPosition(position).equals(getApplicationContext().getResources().getString(R.string.choose_sub))){
//do nothing
} else {
spinner_item = parent.getItemAtPosition(position).toString();
//Toast.makeText(parent.getContext(),"Selected : "+item, Toast.LENGTH_SHORT).show();
}
}
}
and I hope I can get spinner sub value because I need to judge
post.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if( -- how can get spinner value in here? --){
//
}else {
Toast.makeText(getApplication(), getApplicationContext().getResources().getString(R.string.must_upload), Toast.LENGTH_SHORT).show();
}
}
});

If you just want selected spinner item to be used in if(condition=spinner value) on click event of post i.e., post.onClick(), just get the spinner selected item
your code will look like this
post.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(spinner.getSelectedItem().equals("your compare value")){
// do whatever you want
}else {
Toast.makeText(getApplication(), getApplicationContext().getResources().getString(R.string.must_upload), Toast.LENGTH_SHORT).show();
}
}
});

Android spinners dynamic data binding

I am new to android , I have an activity with 3 multiple spinners as bellow
Spinner 1:department
Spinner2:semester
Spinner3:subjects
and one button
spinner1 shows the department on select of department it has to display the semester on select of semester it has to display the subject spinner
NOTE:-SUBJECT SPINNER DEPENDS ON THE SELECTION OF SEMESTER SPINNER AS WELL AS DEPARTMENT SPINNER.
something like country, state, city spinners but suggest me some other ideas to do it because i am using string resources to list the items of spinners
Please help me

Try something like this in your activity.
Firstly, make your activity implement AdapterView.OnItemSelectedListener & View.OnClickListener.
private Spinner mDepartmentSpinner;
private Spinner mSemesterSpinner;
private Spinner mSubjectSpinner;
private Button mButton;
// Values to fill first spinner with.
private String[] mDepartments = {
"Department 1",
"Department 2",
"Department 3",
"Department 4",
};
private String[] mSemesters;
private String[] mSubjects;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initViews();
}
private void initViews() {
// Find the spinners and button, declared in the activity's resource file
mDepartmentSpinner = (Spinner) findViewById(R.id.department_spinner);
mSemesterSpinner = (Spinner) findViewById(R.id.semester_spinner);
mSubjectSpinner = (Spinner) findViewById(R.id.subject_spinner);
mButton = (Button) findViewById(R.id.button);
// Initialise spinner with values, placing them into a textview
mDepartmentSpinner.setAdapter(new ArrayAdapter<String>(getContext(), R.layout.text_view, mDepartments));
// Attach a listener for item selection
departmentSpinner.setOnItemSelectedListener(this);
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// Work out which spinner was selected
switch (view.getId()) {
case R.id.department_spinner:
// Get the selected item
String selectedDepartment = mDepartments[position];
// Get values to fill the semester spinner with, based on initial selection.
mSemesters = getSemestersFor(selectedDepartment);
// Initialise spinner with values, placing them into a textview
mSemesterSpinner.setAdapter(new ArrayAdapter<String>(getContext(), R.layout.text_view, mSemesters));
// Attach a listener for item selection
mSemesterSpinner.setOnItemSelectedListener(this);
break;
case R.id.semester_spinner:
// Get the selected item
String selectedSemester = mSemesters[position];
// Get values to fill the subject spinner with, based on second spinner selection.
mSubjects = getSubjectsFor(selectedSemester);
// Initialise spinner with values, placing them into a textview
mSubjectSpinner.setAdapter(new ArrayAdapter<String>(getContext(), R.layout.text_view, subjects));
// Attach a listener for item selection
mSubjectSpinner.setOnItemSelectedListener(this);
break;
case R.id.subject_spinner:
mButton.setOnClickListener(this);
break;
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
mButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Please select an option from each spinner.", Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onClick(View v) {
// Go to your new activity, passing the selected subject
Intent intent = new Intent(this, SubjectActivity.class);
intent.putExtra("KEY_SUBJECT", (String) mSubjectSpinner.getSelectedItem());
startActivity(intent);
}
You can get the selected subject in the SubjectActivity like so...
#Override
public void onCreate(Bundle savedInstanceState) {
if (getIntent().getExtras().containsKey("KEY_SUBJECT") {
String subject = getIntent().getExtras().getString("KEY_SUBJECT");
}
}
Code for R.layout.text_view
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
You will need to implement the following methods yourself, I don't know your logic!
private String[] getSemestersFor(String department) {
// your code here
}
private String[] getSubjectsFor(String semester) {
// your code here
}

switch case with two spinners and audio player

In my activity i have two spinners, one image view and two buttons.
depending on first spinner the second spinners should change. and while selecting birds in first spinner the second spinner should show parrot peacock etc. while selecting parrot in second spinner i should get the image of parrot.
till this i am getting.
but now what i want is while i press a button then i should get the voice of parrot.
in this code when i am pressing the button i am getting the same voice for every picture change in second spinner
public class MainActivity extends Activity {

}
if(s.equals("Tara_2"))
im.setImageDrawable(getResources().getDrawable(R.drawable.india1));
if(s.equals("Tara_3"))
im.setImageDrawable(getResources().getDrawable(R.drawable.peacock));
if(s.equals("Tara_4"))
im.setImageDrawable(getResources().getDrawable(R.drawable.robin1));
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//MediaPlayer mMediaPlayer = MediaPlayer.create(this,
R.raw.Kalimba);
MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.abc);
mp.start();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

In the setOnClickListener method of your button, b1, you need to know which image has been selected on the spinner (your description is a little bit confusing so i don't have clear exactly which spinner is going to change the sound that you app has to reproduce).
Anyway, let think that the spinner is "friend_options".
In you setOnClickListener we have to know which item has been selected for the user when click on the button, right? And depending of which item was selected, we will play one specific sound.
So....
Another important poin is that you should create the variable of the mediaplayer outside of the onclickListener, like a class variable:
//Class variable:
public MediaPlayer mp;
In the onCreate method you should initialize the MediaPlayer component:
public void onCreate()
{
MediaPlayer.create(MainActivity.this, R.raw.abc); //Default sound, it is not
//importat because we are going
//to chain the value of the
//file to reproduce in the next
//step.
}
b1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Here we are going to take the item selected:
String itemSelected = spinner.getSelectedItem().toString();
int soundToPlayId=0;
if(itemSelected.equals("Nuz"))
{
soundToPlayId = R.raw.Kalimba ;
}
else if(itemSelected.equals("Dur"))
{
soundToPlayId = R.raw.abc;
}
// etc etc etc --> you should put all the sound associated to all the
// friends
//And now you only have to reproduce if the item was selected properly:
if(soundToPlayId !=0) //if the id is different to 0:
{
mp = MediaPlayer.setDataSource(MainActivity.this, soundToPlayId);
mp.start();
}
}
});
Let see if it is working!!! Ask me if you have any doubt...and if the answer is correct, vote me and check as correct!!! (I need points, thanks!)

Android temp update spinner before it gets values from SQLite

I'm wondering if there is some trick to get the spinner updated from an edittext and onClick, before it gets committed to the database and retrieve from there? The list and the spinnerAdapter are set for retrieving values from database, so I'm aware that this question might be stupid.
I was thinking of this logic: enter some text to edittext, click ok, then temporary update the spinner with this text, before it goes to database, then do some other stuff in the activity and last commit everything to database. When you then close and open your activity again, the temporary value is lost, but the spinner gets populatet with the same value, but this time from database.
here is some code:
public class Vnos extends Activity {
//... some values
#Override
protected void onCreate(Bundle savedInstanceState) {
//...
final Spinner spinner = (Spinner) findViewById(R.id.spinner1);
final List<VnosiDB> spinerItems = datasource.getAllNiz();
final ArrayAdapter<VnosiDB> spinnerAdapter = new ArrayAdapter<VnosiDB>(
this, android.R.layout.simple_spinner_item, spinerItems);
spinnerAdapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerAdapter);
String nizIzSpinerja = spinner.getItemAtPosition(
spinner.getSelectedItemPosition()).toString();
nizDB = nizIzSpinerja;
// nov niz
novNiz = (TextView) findViewById(R.id.dodaj);
novNiz.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(Vnos.this,
android.R.style.Theme_Holo_Dialog);
dialog.setContentView(R.layout.nov_niz);
TextView okNov = (TextView) dialog.findViewById(R.id.okNovNiz);
okNov.setOnClickListener(new android.view.View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
EditText inputNiz = (EditText) dialog
.findViewById(R.id.niz);
dialog.dismiss();
nizDB = inputNiz.getText().toString();
spinnerAdapter.notifyDataSetChanged();
}
});
dialog.show();
}
});
// ...some other code...
//...
//.. then, here I commit everything to database...
shrani = (TextView) findViewById(R.id.shrani);
shrani.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
vnosDB = (int) System.currentTimeMillis();
datasource.createVnos(zacetekDB, razlikaDB, nizDB, deloDB,
postavkaDB, dodatekDB, opisDB, vnosDB);
datasource.close();
Toast test = Toast.makeText(Vnos.this, "Vnos " + deloDB
+ " uspešen!", Toast.LENGTH_LONG);
test.show();
startActivity(new Intent("com.sandpit.jazstudent.URE"));
finish();
}
});
}
}

you are using ArrayAdapter, which is loaded by List<VnosiDB>. I assume that VnosiDB represents a record from the database. Why don't you just put a temporary record in this list when you need it?
List<VnosiDB> spinerItems = new ArrayList<VnosiDB>();
VnosiDB tempRec = new VnosiDB();
//set some values to the properties if you need to
spinnerItems.add(tempRec);
//populate the spinner with the temp record

How to store dropdown item of the spinner to the sqlite database of android

I want to store the dropdown value of the spinner to the database. I am able to get dopdown as per the tutorial in the android developer site but i am not able to store that dropdown value to the database when user click on save button.I don't know it is possible or not if yes please tell me how to do that with some example.
Thanks in advance

}
};
}

If you're looking for information on how to use SQLite databases in an Android app, I highly recommend going through the Notepad tutorial.
Or are you stuck at handling the button click?

This doesn't directly answer the question, but design-wise and for simplicity's sake it may make some sense to store UI values as preference.
For example:
public static final String PREFS_NAME = "MyPrefsFile";
public static final String SPINNER_VALUE = "SPINNER VALUE";
SharedPreferences settings = getSharedPreferences(PREFS_NAME , 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString(SPINNER_VALUE, <the spinner value>);
editor.commit();
Of course this depends on your requirement, ymmv.
