Not showing selected item from spinner in android? - android

i have 3 spinners if i select something it should show items related with that selection .But its showing all the item from server and not taking selected item.
In getdata() methode in code i am getting all item without selection .
In filter() methode i need to show only selected item, but its still showing all item.
here is my code:

here is my json output:

"usr_mobile": "+971/505040009",
"usr_image": "http://....19a.jpeg",
"usr_email": "...edo#gmail.com"
},

you don't changed adapter data.
try this code.
#Override
protected void onPostExecute(Void result) {
progressDialog.dismiss();
listItems3.addAll(list);
adapter3.clear();
adapter3.addAll(listItems3);
adapter3.notifyDataSetChanged();
ArrayAdapter<String> array_spinner = (ArrayAdapter<String>) lsCountry.getAdapter();
lsCountry.setSelection(array_spinner.getPosition(PostCountry));
}

You can Log your post parameters i think you should do :
final String lstrain = (String)lsStrain.getSelectedItem();

Thread exiting with uncaught exception on a specific function

Im developing an android app that performs add, update, and delete operations on data on a localhosted MySQL Database. Everything is working fine except for the update part. It happens on the activity ViewFeedingSched when im trying to update the data. The app crashes when the update button is pressed or simply when the function for updating is called. The logcat is giving a message: threadid=1: thread exiting with uncaught exception (group=0x41640c80) . I've seen several solutions and they're mostly about not initializing some objects or having null values. I can't seem to find where I have not initialized something. It was working before and I don't know what I've changed with the program. Below is the codes of the ViewFeedingSched class.
EDIT
I've added the codes for the class that goes before the ViewFeedingSched class which is the FeedingSchedList class. It's layout contains a ListView with the data being listed, and an onItemClick method that opens the ViewFeedingSched class whenever an item (data) is clicked.
public class ViewFeedingSched extends AppCompatActivity implements View.OnClickListener {

how to show only selected data when spinner value is selected in android?

I have got 3 spinner where data is coming from server, if we click the search button without selecting any spinner then on next activity , it should show all list(all product without condition), but if we select according to 3 spinner then it should show only related item.I am getting all item when clicking search button without selecting anything but i am not getting selected item in next activity .
here is my Search Activity:

In Pigeon listing activity there is 1 option like search activity where user can search without selecting any item just like in search activity.
Set listeners for each of your spinners
setOnItemSelectedListener
In onItemSelected method , get the selected value in a variable and pass on these values to next activity.
E.g.
yourSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String yourValue = yourSpinner.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

From onSaveInstanceState documentation:
Called when the LayoutManager should save its state. This is a good time to save your
* scroll position, configuration and anything else that may be required to restore the same
* layout state if the LayoutManager is recreated.
* RecyclerView does NOT verify if the LayoutManager has changed between state save and
* restore. This will let you share information between your LayoutManagers but it is also
* your responsibility to make sure they use the same parcelable class.
To get current state of recyclerview:
private Parcelable recyclerViewState = recyclerView.getLayoutManager().onSaveInstanceState();
to restore saved instance:
recyclerView.getLayoutManager().onRestoreInstanceState(recyclerViewState);
