    message = (EditText)findViewById(R.id.put_message);


    preferences = getSharedPreferences(shared_preferences,Context.MODE_PRIVATE);
    editor = preferences.edit();
    spinner = (Spinner)findViewById(R.id.sos_spinner);

    String[] hospital = getResources().getStringArray(R.array.hospital);
    ArrayAdapter<String> adapterhospital = new ArrayAdapter<String>(this ,android.R.layout.simple_list_item_1, hospital);
    spinner.setAdapter(adapterhospital);

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            editor.putInt(String.valueOf(getResources().getStringArray(R.array.number)),   R.array.hospital);

            editor.commit();

        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    button = (Button)findViewById(R.id.save_btn);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String getMessage = message.getText().toString();
            int getPhonenum = Integer.parseInt(phonenum.toString());

            editor.putInt(stored_phonenum, getPhonenum);
            editor.putString(stored_message , getMessage);
            editor.commit();

            Toast.makeText(HowtoActivity.this, "Data Saved.",
                    Toast.LENGTH_SHORT).show();
        }
    });
}

Answer 1

I would recommend creating the array using java as opposed to xml.

Its quite simple,

ArrayList<String> hospitals= new ArrayList<>();

then add the hospitals to this array list this way :

hospitals.add("Hospital 1");
hospitals.add("Hospital 2");
hospitals.add("Hospital 3");

Note that this(hospitals array) is the array you will be storing in your spinner.

For the task you want to achieve, this is how i would proceed to do it : You can have one more arraylist to store both hospital and its respective number seperated by a comma(,): So create another arrayist, lets call it numbers.

ArrayList<String> numbers = new ArrayList<>();
numbers.add("Hospital 1,71955555");
numbers.add("Hospital 2,71955556");
numbers.add("Hospital 3,71955557");

Now once the user selects an item on the spinner, use the onItemSelected to get the value and store it in shared preferences.

Now just loop through the number arrayList and collect the number if your selected value is equal to the hospital name. You can split the value where the comma is. This way :

for(int i=0;i<numbers.size();i++){

    String value = numbers.get(i);
    String names[]= value.split(",");
    String name = names[0];
    if(name.equalsIgnoreCase("Value stored from spinner"){
    String number = names[1];
    //Store this number in shared preferences as the value for the hospital //selected
}

}

From here you can call the hospital number from your shared preferences in any activity where it is needed.

You can use xml pull Parser for this purpose. Create an xml like this

 <?xml version="1.0" encoding="utf-8"?>
<resources>
<hospital>
    <hospital>
        <a_name>hospital 1</a_name>
        <a_number>71955555</a_number>
    </hospital>
   <hospital>
        <a_name>hospital 1</a_name>
        <a_number>71955555</a_number>
    </hospital>
    <hospital>
        <a_name>hospital 1</a_name>
        <a_number>71955555</a_number>
    </hospital>
    <hospital>
        <a_name>hospital 1</a_name>
        <a_number>71955555</a_number>
    </hospital>
</hospitalprovider>
