wish of those help Both country and countrylist ArrayList size is same, easy way to set selected item in Spinner is: get index of countries_id from country and pass it to Spinner setSelection method.like:

code :

int defaultSelectedIndex=0;
for (int i = 0; i < regjsonarray.length(); i++) {
   // your code here
    String strCountrie_Id=regjsonobject.optString("countries_id");
    if(strCountrie_Id.equalsIgnoreCase(gcountries_id)) 
     defaultSelectedIndex=i;                  
}

spinnerCountry.setSelection(defaultSelectedIndex);

Hope this helps First you have to retrieve the text from the spinner correctly, did you do that? If not, this is how to do it:
Assuming you called your spinner spinner.

code :

Spinner mySpinner = (Spinner)findViewById(R.id.spinner);
String txtFromSpinner = mySpinner.getSelectedItem().toString();

if (txtFromSpinner.equals("bla bla bla") && txtFromSpinner2.equals("ho ho ho")
{
   Log.E("Well done sir.","Comparison complete!");
   //Code
}

will help you Finally came across this which helped me, I changed my InitialSetupUI function to this:

code :

public void uniSpinnerSetup()
{
    ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() {
        public ParseQuery create() {
            ParseQuery query = new ParseQuery("University");
            return query;
        }
    };

    uniSpinner = (Spinner) findViewById(R.id.uniSpinner);

    ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>(this, factory);
    adapter.setTextKey("name");
    uniSpinner.setAdapter(adapter);
    uniSpinner.setSelection(1);
    uniSpinner.setOnItemSelectedListener(new mySpinnerListener());

should help you out You forgot to retrieve the currently selected item of your spinner & save it to your spinner1x string, & to implement the onNothingSelected method:

code :

spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> mRelative, View selectedItemView, int position, long id) {
          spinner1x = mRelative.getItemAtPosition(position).toString();
          // your code here
          if (spinner1x.equals("poison")){
              spinner2.setVisibility(View.VISIBLE);
              spinner3.setVisibility(View.GONE);
          }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
        // Another interface callback
    }
});
