android:opening new intent in spinner view - android

I am making an app in which i have to use spinner view to show some items and i want on click of item it should go to that page. i want when i clicke on spanish i should go to spanish pageMy code is as follows.
System.out.println("test1");
Spinner spinner = (Spinner) findViewById(R.id.spinner);
System.out.println("test2");
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.models, android.R.layout.simple_spinner_item);
System.out.println("test3");
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
System.out.println("test3");
spinner.setAdapter(adapter);
System.out.println("test4");
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}

You have to write intent in your onItemSelected method for page/activity which you want to open.
and set position for that.
#Override
public void onItemSelected(AdapterView<?> adaptername, View view,int position, long id)
{
if(position==0)
{
// write the intent for page which you want to open
}
if(position==1)
{
//
}
.
.
.
and same
}

spinner setOnItemSelectedListener does not working

anybody can help! the spinner listener doesn't work by this fragment.
it's never called
I have tried to implement an AdapterView.OnItemSelectedListener
I try to implement the spinner in Fragment I don't know if that really matter
Java code
'''
Spinner mSpinner = (Spinner) view.findViewById(R.id.usernameSpinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_spinner_item, users);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(adapter);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.d(TAG, "onItemSelected: " + position);
//its never called
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
'''

How do I know the position of selected item in spinner?

I am inflating Spinner along with that I am also inflating some other views
LinearLayout child_linear = (LinearLayout) findViewById(R.id.child_linear);
LayoutInflater inflater = getLayoutInflater();
View myView = inflater.inflate(R.layout.add_custome_layout, child_linear, false);
name = (TextView) myView.findViewById(R.id.name);
price = (TextView) myView.findViewById(R.id.add_price);
names_spinner = (Spinner) myView.findViewById(R.id.product_addmore_spinner);
child_linear.addView(myView);
Now I getting data for the spinner. The question if there are 'n' no.of spinners how do I know which spinner item user selected?
names_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
parent.getItemAtPosition(position).toString();
if (parent.getItemAtPosition(position).toString().equalsIgnoreCase("Select Toppings")) {
//Show PopUp or Alerts
Toast.makeText(ProductView.this, "position" + names_spinner.getItemIdAtPosition
(position), Toast.LENGTH_SHORT).show(); }
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Even when I click on particular spinner item position is also not showing in Toast. What's my mistake?
You are showing toast only when user click on Select Toppings. Take a look to your code:
if (parent.getItemAtPosition(position).toString().equalsIgnoreCase("Select Toppings")) {
Change this line for
if (!parent.getItemAtPosition(position).toString().equalsIgnoreCase("Select Toppings")) {
And alerts should be shown.
Additionally to know which item is clicked, the listener provided you the clicked position, you can search in you items array this position and you can know which item is.
EDIT:
Now, lets suppose you have more than one spinner. spinner1 and spinner2, for example. You could register an OnItemSelectedListener for each one.
Then you can create a global variable called Spinner clickedSpinner and inside the OnItemSelectedListener of the spinner1 you set the clickedSpinner to spinner1 and inside the OnItemSelectedListener of the spinner2 set the clickedSpinner to spinner2:
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
clickedSpinner = spinner1;
... // Do your stuff here
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
And:
spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
clickedSpinner = spinner2;
... // Do your stuff here
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
So, after clicking any item of any Spinner you can now know which Spinner was clicked because is stored in clickedSpinner.
Please note that this variable is not mandatory, you could achieve the same behavior without this global variable, because in each OnItemSelectedListener you know which spinner is the clicked. So, you could do the following:
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
int spinner1Position = spinner1.getItemIdAtPosition(position);
... // Do your stuff here
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
And:
spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
int spinner2Position = spinner2.getItemIdAtPosition(position);
... // Do your stuff here
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
Without using a global variable.
Hope this helps.
Try this
final Spinner names_spinner = (Spinner) myView.findViewById(R.id.product_addmore_spinner);
ArrayAdapter<String> madapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, getResources().getStringArray(R.array.yourarray));
madapter.setDropDownViewResource(android.R.layout.simple_list_item_1);
names_spinner.setAdapter(madapter);
names_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
String mySpinner = (String) adapterView.getItemAtPosition(i);
Log.i("names_spinner",mySpinner);
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
Toast.makeText(getApplicationContext(),"Your Message",Toast.LENGTH_LONG).show();
}
});
}

Cannot get current spinner position with setOnItemSelectedListener

I am trying to retrieve the spinner's selected position. The values inside the spinner are of type String and I am using setOnItemSelectedListener to change a class String variable to the one that has been selected and use it later on:
spinner = (MaterialBetterSpinner) myToolbar.findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,socialMediaOptions);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
socialMedia = parent.getItemAtPosition(position).toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
private void sendPost(){
Log.v(TAG, socialMedia);
}
The problem is that the variable does not change when an item is selected, it seems like onItemSelected is not being called when there is a change in the spinner selection
See this thread:
https://github.com/Lesilva/BetterSpinner/issues/42
There said that BetterSpinner extends EditText, that's why onItemSelectedListener is not being called. You should use TextChangedListener instead.
Hope your socialMediaOptions are string array like this
socialMediaOptions={"FB","TWIT","IN"}
then
// Specify the layout to use when the list of choices appears
add this line
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
socialMedia = socialMediaOptions[position];
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

spinner with ItemSelected

// Apply the adapter to the spinner

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
// Do something
}
#Override
public void onNothingSelected(AdapterView<?> adapter) {
}
});
thanks
As I understand your question , you want to get the selected item.
In:
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
CharSequence item = (CharSequence)adapterView.getAdapter().getItem(position);
}
For custom adapter which can contain any other objects (not only CharSequence), see this link for example

multiple spinner's simple doubts

Im new to android. i have tried to built an application which has 2 spinner...
i have few doubts to clear before going deep to my application..
please give brief answer to my question...
is it possible to have 2 spinners in one view?
can i add setOnItemSelectedListener(this) for both?
if yes, how could i know which option is selected on both the spinners? like spinner.getSelectedItemPosition(); on both the spinners?
waiting for ur valuable replies. reference materials are also appreciable
Yes, you can have multiple spinner's that can be managed by single listener or you can have seperate Listener for each.
For Single Listener you can do something like this,
Set the Listener
spinner1.setOnItemSelectedListener(this);
spinner2.setOnItemSelectedListener(this);
Then you can use onItemSelected to get perform the action related to the spinner's.
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position,long arg3)
{
int id = parent.getId();
switch (id)
{
case R.id.spinner1:
// your stuff here
break;
case R.id.spinner2:
// your stuff here
break;
}
Check this:
Spinner spinner0, spinner1, spinner2;
TextView textView0, textView1, textView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView0 = (TextView) findViewById(R.id.text0);
spinner0 = (Spinner) findViewById(R.id.spinner0);
ArrayAdapter<String> adapter0 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text0);
adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner0.setAdapter(adapter0);
spinner0.setOnItemSelectedListener(onItemSelectedListener0);
textView1 = (TextView) findViewById(R.id.text1);
spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text1);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner1.setSelection(0,false); //make sure only one listener is
//active in the onCreate method by setting the other listener as false
spinner1.setOnItemSelectedListener(onItemSelectedListener1);
textView2 = (TextView) findViewById(R.id.text2);
spinner2 = (Spinner) findViewById(R.id.spinner2);
MySpinnerAdapter adapter2 = new MySpinnerAdapter(MainActivity.this, android.R.layout.simple_spinner_item, obj2);
//adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner2.setAdapter(adapter2);
spinner2.setSelection(0,false);
spinner2.setOnItemSelectedListener(onItemSelectedListener2);
}
OnItemSelectedListener onItemSelectedListener0 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner0
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
OnItemSelectedListener onItemSelectedListener1 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner1
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
OnItemSelectedListener onItemSelectedListener2 = new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//do your stuff spinner2
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
};
}
If the reference of two spinners are different(which will be , if you are using 2 spinners) , give different IDs for them and you can uniquely identify them, Yes you can set click listener to both of them individually.
spinner.setOnItemSelectedListener(new OnItemSelectedListener() { ... } );
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() { ... } );
yes
yes
spinner1.getSelectedItemPosition(), spinner2.getSelectedItemPosition()
