I looked at the URL's that you provided and tried some coding with it, but I am failing to understand the proper coding methods.
In the main, I have the options menu as: // options menu // Called only the first time the options menu is displayed. // Create the menu entries. // Menu adds items in the order shown. public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); menu.add("Setup") .setIcon(android.R.drawable.ic_menu_preferences); menu.add("About") .setIcon(android.R.drawable.ic_menu_info_details); return(super.onCreateOptionsMenu(menu)); //return true; } // handle menu selected public boolean onOptionsItemSelected(MenuItem item){ if (item.getTitle().equals("Setup")){ Intent intent = new Intent(this, com.tccalculator.setup.class); startActivityForResult(intent, MY_SETUP); return true; } if (item.getTitle().equals("About")){ Intent intent = new Intent(this, com.tccalculator.about.class); startActivityForResult(intent, MY_ABOUT); return true; } return(super.onOptionsItemSelected(item)); //return false; } I believe that I need this to read the preferences still in the main and set a textview as such: public void onResume() { super.onResume(); SharedPreferences prefs=PreferenceManager .getDefaultSharedPreferences(this); TextView tv = (TextView) findViewById(R.id.TextView01); tv.setText(prefs.getString("tview1", "")); The preference name for this textview is called "tview1". According to the example, it looks like you have to give it a value. I just want to read that preference, and take the value it has, and place it in the TextView01 text but according to the example, you have to give it a value. In the setup, I created this: @Override protected void onStop(){ super.onStop(); // We need an Editor object to make preference changes. // All objects are from android.context.Context SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); SharedPreferences.Editor editor = settings.edit(); editor.putString("tview1","this is a test"); // Commit the edits! editor.commit(); } The PREFS_NAME was declared at the top: public static final String PREFS_NAME = "calcsettings"; If I am following this, the "editor" creates the name/value pair ("tview1" = "this is a test") then writes it to the preferences by calling the editor.commit(); What am I doing wrong? As I am testing, I am attempting to creating/ retrievie one preference (name/value). Thanks again for all your help. :RB On Sep 30, 4:59 pm, Mark Murphy <mmur...@commonsware.com> wrote: > On Thu, Sep 30, 2010 at 6:51 PM, rb <rbs...@gmail.com> wrote: > > Thanks for shedding some light on this issue. > > > Here's some of my code: > > :: snip :: > > > I was going to save and read the data from a file which would be > > stored > > in the phones default applications directory as one file. > > All the more reason to use a PreferenceActivity. > > > Not sure how you would use the preference activity for storing name/ > > values as > > I need to store and retrieve 6 different items. > > Ever looked at the Settings application in your device?
