using shared peferences to save colors <p>I have an app that uses a color picking dialog to change the app background color, and the text color. The color picker works fine, but when the app closes for any reason it reverts back to default. </p> <p>I have checked: <a href="http://developer.android.com/guide/topics/data/data-storage.html#pref" rel="nofollow">http://developer.android.com/guide/topics/data/data-storage.html#pref</a> and <a href="http://stackoverflow.com/questions/23024831/android-shared-preferences-example">Android Shared preferences example</a></p> <p>the below code is the result of my research. The problem I'm having is all my text fields start off without text color, when i use the color dialog the colors change just fine, but are not saved. </p> <p>Any pointers on where I'm going wrong would be greatly appreciated.</p> <pre><code>public class TipCalculator extends ActionBarActivity implements ColorPickerDialog.OnColorChangedListener { //UI element objects to be manipulated. TextView tipper; TextView diner; /*few TextView items left out to save space*/ int color; RelativeLayout RLayout; private SharedPreferences preferences; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tip_calculator); preferences = getSharedPreferences("TipCalculator", MODE_PRIVATE); //color = preferences.getInt("TipCalculator", color); did not change anything color = preferences.getInt("bg_color", color); RLayout = (RelativeLayout) findViewById(R.id.RLayout);//layout object for background color manipulation bill = (EditText) findViewById(R.id.bill_amount_text);//UI elements placed in objects for text color manipulation billNtip = (TextView) findViewById(R.id.bill_tip_text); /*few TextView items left out to save space*/ bill.setSelection(bill.getText().length()); bill.addTextChangedListener(billWatcher); } @Override public void onPause(){// onStop does not seem to change how the app currently runs super.onPause(); /*preferences = getSharedPreferences("TipCalculator", MODE_PRIVATE); SharedPreferences.Editor editor = preferences.edit(); does not work*/ SharedPreferences.Editor editor = getSharedPreferences("TipCalculator", MODE_PRIVATE).edit(); //editor.putInt("TipCalculator", color); does not change anything editor.putInt("bg_color", color); editor.commit(); tipper.setTextColor(color); bill.setTextColor(color); /*few TextView items left out to save space*/ } @Override public void colorChanged(String key, int color) { color = newColor; if (decide.equals("font")) { tipper.setTextColor(color); bill.setTextColor(color); /*few TextView items left out to save space*/ } else if (decide.equals("background")) { RLayout.setBackgroundColor(color); } } </code></pre>
