java - App chrashes when I click button and select item on spinner -

According to what object is selected on the spinner, I want to take a certain action on the button press. This is what I have so far received:

  public void submitButton (see V) {button b1 = (button) findViewById (R.id.submitButton); Final Spinner S1 = (Spinner) Find VVBIID (RID Spinner 1); Final Reference Reference = This; b1.setOnClickListener (New View.OnClickListener () {@Override public void onClick (View v) {final int status = s1.getSelectedItemPosition (); switch (status) {case 0: AlertDialog.Builder spinnerErrorBuilder = new AlertDialogkBuilder (reference ) (( "OK", the new DialogInterface.OnClickListener (spinnerErrorBuilder.setPositiveButton "warning"), SpinnerErrorBuilderksetMessage () "Please select an item from the list") {@Override public void onClick (DialogInterface communicate, spinnerErrorBuilder.setTitle Int id) {dialog.cancel ();}}); Alert Dealog Spinner Ehrtar = Spinner IrrBilder.Create (); Spinner Err. Show (); B Rake; case 1: break;}}}); }   
 When I compile my app and click on the button, the app crashes and returns to main activity, it does not matter what item The selected (0 or 1) app is still crashing.  
  & lt; Button Android: id = "@ + id / submitButton" Android: Layout_width = Can anyone tell me where I went wrong?  
 "wrap_content" Android: layout_height = "wrap_content" Android: layout_alignBaseline = "@ + id / editText1" Android: layout_alignBottom = "@ + id / editText1" Android: layout_alignLeft = "@ + id / checkBox25" Android: Text = "Add to String / Content" Android: onClick = "onClick" />

 Your method is named  submitButton  but your onClick method has xml  onClick   
 Change it is  submitButton  and your problem is resolved  
 should be XML
