How to set Spinner text in android coming from server

Question

I am working on android application in which i am getting string values from server. I want to set display text of my spinner from string value coming from server. For example if it String value from server is "O+" then the display text of the spinner should be "O+". Given below is my code, please guide me for this.

 private String[] state = { "O-", "O+", "A-", "A+", "AB-", "AB+", "B-", "B+" }; Spinner spinnerOsversions; spinnerOsversions = (Spinner) findViewById(R.id.spinner_BloodGroup); ArrayAdapter<String> adapter_state = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, state); adapter_state.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinnerOsversions.setAdapter(adapter_state); spinnerOsversions.setOnItemSelectedListener(this);

Get values from server with help of a webservice and store in an array of strings / objects and use adapter for same. — Kanak Sony

Suppose your server text contains as one of its choices: "O+".

To find and compare the position of "O+" in the Spinner use this:

 String CompareValue= "O+"; if (!CompareValue.equals(null)) { int SpinnerPostion = adapter_state.getPosition(CompareValue); spinnerOsversions.setSelection(SpinnerPostion); SpinnerPostion = 0; }

works like a charm.. Thank you so much. Can you pleas just explain me the meaning of (!CompareValue.equals(null))? Why you are comparing it with null value?
Just for avoid null pointer exception.. Incase your server value return error.

 String[] stateArray = { "O-", "O+", "A-", "A+", "AB-", "AB+", "B-", "B+" }; String statePosition = ""; for (int i = 0; i < stateArray.length; i++) { if (stateArray[i].equals(result.getStateSelected())) { // result.getStateSelected() is your service response statePosition = stateArray[i]; return ; } } spinnerOsversions.setSelection(adapter.getPosition(statePosition), true);
