Saving Spinner value to SharedPreferences then setting the Spinner to that saved String

Question

I have a Spinner named strength that I need to grab its value and save it to SharedPreferences. Then when the user starts the same activity (SaAStrength) again, the Spinner named strength needs to be set to what they already selected.

The code I have currently doesn't set the spinner to the saved string in Prefs.

I'm quite lost as to how to approach this.

package com.mikitz.rogsimple;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class SaAStrength extends Activity {

Spinner strength, melee, h2h, parry; 

SharedPreferences pref;

String getstrength, getmelee, geth2h, getparry; 

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.saa_strength);
    pref = getSharedPreferences("Character1", Context.MODE_PRIVATE);

    strength = (Spinner) findViewById(R.id.strength);

    strength = (Spinner) findViewById(R.id.strength);
    Integer[] items1 = new Integer[]{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30};
    ArrayAdapter<Integer> adapter1 = new ArrayAdapter<Integer>(this,android.R.layout.simple_spinner_item, items1);
    strength.setAdapter(adapter1);

    melee = (Spinner) findViewById(R.id.melee);
    Integer[] items2 = new Integer[]{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30};
    ArrayAdapter<Integer> adapter2 = new ArrayAdapter<Integer>(this,android.R.layout.simple_spinner_item, items2);
    melee.setAdapter(adapter2);

    h2h = (Spinner) findViewById(R.id.h2h);
    Integer[] items3 = new Integer[]{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30};
    ArrayAdapter<Integer> adapter3 = new ArrayAdapter<Integer>(this,android.R.layout.simple_spinner_item, items3);
    h2h.setAdapter(adapter3);

    parry = (Spinner) findViewById(R.id.parry);
    Integer[] items4 = new Integer[]{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30};
    ArrayAdapter<Integer> adapter4 = new ArrayAdapter<Integer>(this,android.R.layout.simple_spinner_item, items4);
    parry.setAdapter(adapter4);

    getstrength = pref.getString("strength", "");
    strength.setSelection(((ArrayAdapter)strength.getAdapter()).getPosition(getstrength));
}

public void onBackPress()
{
    SharedPreferences.Editor editor=pref.edit();

    editor.putString("strength", strength.getSelectedItem().toString());

    editor.commit();

    Toast.makeText(this, "GREAT SUCCESS!!!!", Toast.LENGTH_LONG).show();

    Intent intent = new Intent (this, NewSkillsAndAttributes.class);
        startActivity(intent);
}
}

you have two `strength = (Spinner) findViewById(R.id.strength);` — Sagar Pilkhwal, Sep 09 '14 at 08:58
look into this [post](http://stackoverflow.com/a/3624358/3326331) — Sagar Pilkhwal, Sep 09 '14 at 09:03
hey is this `onBackPress()` method being alled from `@Override public void onBackPressed() { ..}` ? — Sagar Pilkhwal, Sep 09 '14 at 09:07
@SagarPilkhwal hahaha that fixed the saving to Prefs issue. But the code I have up there doesn't set the spinner to the saved string. — Mikitz06, Sep 09 '14 at 09:47
try `getstrength = pref.getString("strength", null);` and then `if(getstrength !=null){..}` check if it is null — Sagar Pilkhwal, Sep 09 '14 at 09:54
Check what does this give? : `Toast.makeText(this, " index : "+((ArrayAdapter)strength.getAdapter()).getPosition(getstrength), Toast.LENGTH_LONG).show();` — MysticMagicϡ, Sep 09 '14 at 09:55
@Dhruti is said `index: -1` It says that no matter what value I put in the spinner — Mikitz06, Sep 09 '14 at 10:09
You checked after `getstrength = pref.getString("strength", "");` line, right? — MysticMagicϡ, Sep 09 '14 at 10:23
And check this too: `Toast.makeText(this, " getStrength: "+getStrength, Toast.LENGTH_LONG).show();` — MysticMagicϡ, Sep 09 '14 at 10:27
The string is `getstrength` not `getStrength`. I'm not sure what you mean. — Mikitz06, Sep 09 '14 at 10:58
@Mikitz06 check your String getstrength's value. I made a typo. check toast of `Toast.makeText(this, " getstrength: "+getstrength, Toast.LENGTH_LONG).show();` . Is it proper? the string shows what you selected in spinner? — MysticMagicϡ, Sep 09 '14 at 11:40
I don't think it's proper as the index value is always -1 no matter the value I select in the spinner — Mikitz06, Sep 09 '14 at 14:47
