Я пытаюсь добавить элементы на spinner, используя метод fillHymNumber, когда он не обновляется. в журналах

Ниже Ошибок не является основным видом деятельности, как это:

public class MainLayoutActivity extends AppCompatActivity 
     implements NavigationView.OnNavigationItemSelectedListener { 
    private static final String DB_NAME = "yourdbsqlite3.db"; 
    private SQLiteDatabase database; 
    private String TABLE_NAME="ENGLISH",SongTittle, hymn_number_selected = "702"; 
    private ArrayList HymNumber_Array,HymtitleSearch_Array,songNumber_Array; 
    private ScrollView song_scrolview ; 
    private TextView song_textview; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main_layout); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     //Controls Defination 
     song_scrolview = (ScrollView) findViewById(R.id.song_scrollview); 
     song_textview = (TextView) findViewById(R.id.song_textview); 



     //DB key helper - initialize SQL lite DB 
     ExternalDbOpenHelper dbOpenHelper = new ExternalDbOpenHelper(this, DB_NAME); 
     database = dbOpenHelper.getReadableDatabase(); 

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
     fab.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
         .setAction("Action", null).show(); 
      } 
     }); 

     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
     ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
       this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
     drawer.setDrawerListener(toggle); 
     toggle.syncState(); 

     NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
     navigationView.setNavigationItemSelectedListener(this); 


    }

     } else {

     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main_layout, menu); 

     return true; 
    } 

    @Override

     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml.

     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 

     private void fillHymNumber(String lang) { 
    //Spinner spinner2 = (Spinner) findViewById(R.id.song_number_spinner); 
    ArrayAdapter<String> dataAdapter; 
    View view = getLayoutInflater().inflate(R.layout.spinnerlayout, null); 
    Spinner spinner2 = (Spinner) view.findViewById(R.id.song_number_spinner);

    List<String> list = new ArrayList<String>(); 
    list.add("1"); 
    list.add("2"); 
    list.add("3"); 

    dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,list); 
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_item); 
    spinner2.setAdapter(dataAdapter); 
} 

    @SuppressWarnings("StatementWithEmptyBody") 
    @Override 
    public boolean onNavigationItemSelected(MenuItem item) { 
     // Handle navigation view item clicks here. 
     int id = item.getItemId(); 

     if (id == R.id.nav_english) { 
     fillHymNumber("english"); 
    } else if (id == R.id.nav_tsonga) { 
     fillHymNumber("tsonga"); 
    } else if (id == R.id.nav_sotho) { 
     fillHymNumber("sotho");

     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
     drawer.closeDrawer(GravityCompat.START); 
     return true; 
    } 
}

Terrence, похоже, что fillHymNumber не является вызовом в вашем коде.
