Help transfering from app inventor to intellij Idea

Hi,

I have created a simple app on app inventor that makes use of TinyDB.

I store a series of values (fixed values), which I can select using a spinner.

the values pull in a series of fixed values.

I can then modify these values and save them to a working set, the working set of values load up at default.

I want to convert my app into code  and I am ploding along slowly.

Can anyone help point things out please.

How it works:-

1. select option with spinner

2. the option pulls in fixed data, which varies for each selection of the spinner.

3. these values can be modified and saved for a working set of values. the orignal values still remain in tact and can be recalled if someone makes a mistake and they can start with the default values.

Example:-

Tinydb app inventor:-

procedure series 1,2,3,4

series 1:- (these are fixed values and dont change)

apptag                   value 1

headertag              value 2

titletag                    value 3

series 2:- (these are fixed values and dont change)

apptag                   value 1A

headertag              value 2A

titletag                    value 3A

series 3:- (these are fixed values and dont change)

apptag                   value 1B

headertag              value 2B

titletag                    value 3B

series 4:- (these are fixed values and dont change)

apptag                   value 1C

headertag              value 2C

titletag                    value 3C

series working set:-

apptag                    as selected

headertag               as selected

titletag                    as selected

the best I have managed is that before I save to the working set, outside of app inventor, I can select my different values, once selected I can not go back without ressetting my data in applications manager.

However, I need to be able to pull in the default values at will and not reset the app to go back.

what I have done:-

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

           public void onItemSelected(AdapterView<?> arg0, View arg1,
                                      int arg2, long arg3) {

               int index = arg0.getSelectedItemPosition();
               // storing string resources into Array
               spinner = getResources().getStringArray(R.array.spinner_array);

               Toast.makeText(getBaseContext(), "You have selected : " +spinner[index],
                       Toast.LENGTH_SHORT).show();

I have done this using if (index === 0){

apptag.setText(settings.getString("app_tag", "value1")); } else{

and so on for all the possabilities,  the problem being the command setText......  only updates if there are no entries already saved, hence I can select on first use and then cant select anymore without resetting.

I  want the code to be clean and smart and understanderable.

I think the best way would be to have files with all the options in theres about 20 options per series and 20 series, so there is quite a few to go at.

Call the files  so they are read and go the editTex id  and saved  ready to be used by the app, but if I want to i can go and select another set of presets and run them.

Please be gentle new to hard code, all tutorials you can recommend or methods i can try for this implimenattion with  maybe a litle guide on what each bit does I would be greatful, the shared preferences and other tutorials have got me this far but it is in room for some serious improvement.

Thanks
