Save Variable In Sharedpreferences Based On Which Button Is Clicked

Im trying to make an EULA for my app, but there is a different EULA for the different countries we work with. my idea was that i save a String in SharedPreferences like ZA for Sout

Solution 1:

I think you're better off with using IntentExtras, in your first activity upon clicking the country button store the value inside a variable and when you want to start the new activity pass the data as an intent extra:

Intent intent= newIntent(getActivity(), NewActivity.class);
intent.putExtra("country", countryCode);
startActivity(intent);

And then inside the new activity you can retrieve the value like this:

StringcountryCode= getIntent().getExtras().getString("country");

Solution 2:

In order to maintain Shared preference across the application i use it this way , take a look

I saved a AppPrefes class as a seprate class in the package

publicclassAppPrefes {

    privateSharedPreferences appSharedPrefs;
    privateEditor prefsEditor;

    publicAppPrefes(Context context, StringPreferncename) {
        this.appSharedPrefs = context.getSharedPreferences(Preferncename,
                Activity.MODE_PRIVATE);
        this.prefsEditor = appSharedPrefs.edit();
    }

    /****
     * 
     * getdata() get the value from the preference
     * 
     * */publicStringgetData(String key) {
        return appSharedPrefs.getString(key, "");
    }

    publicIntegergetIntData(String key) {
        return appSharedPrefs.getInt(key, 0);
    }

    /****
     * 
     * SaveData() save the value to the preference
     * 
     * */publicvoidSaveData(StringTag, String text) {
        prefsEditor.putString(Tag, text);
        prefsEditor.commit();
    }

    publicvoidSaveIntData(String key, int value) {
        prefsEditor.putInt(key, value);
        prefsEditor.commit();
    }

    /**
     * delete all AppPreference
     */publicvoiddeleteAll() {
        this.prefsEditor = appSharedPrefs.edit();
        this.prefsEditor.clear();
        this.prefsEditor.commit();
    }

In your Activity or Fragment were you would like to get or save data just use it like this

Decalre an object for the AppPrefes class

AppPrefes appPref;

Initialize in onCreate

appPref = new AppPrefes(getActivity(), "type name of your preference");

To save data to the preference use

appPref.SaveData("tag_name", "value to be saved);

To get data from the preference

appPref.getData("tag_name");

You can also save Integer values and clear all preference values if necessary just call the apporopriate methods.

Solution 3:

Yes, the storing part is correct. Now you will need to access the stored value in your new activity.

Example-

SharedPreferencesprefs= getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
StringstoredCountry= sharedpreferences.getString("Country_Selected"); // could be null value if there is no value stored with Country_Selected tag.
