Question

I am having three files in xml folder

beginning_text.xml
preferences.xml
caller.xml

All three files are used as SharedPreferences file

Can i use all three files as

PreferenceManager.setDefaultValues(this, R.xml.sms_beginning_text, false);
       addPreferencesFromResource(R.xml.sms_beginning_text);

PreferenceManager.setDefaultValues(this, R.xml.preferences, false);
       addPreferencesFromResource(R.xml.preferences);

PreferenceManager.setDefaultValues(this, R.xml.caller, false);
       addPreferencesFromResource(R.xml.caller);

and then reading it like:

SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

or how can i read and save 3 different files?

Answer 1

Declare the names of your preference files and while retriving the preferences, mention the name of that file which you want to access in getSharedPreferences().

Here I declare two file names : PrefFile and PrefFileNEW; then I pass the respective names to the getSharedPreference() while retrieving the preferences.

public static final String PREF_FILE_NAME = "PrefFile";
public static final String PREF_FILE_NAME_NEW = "PrefFileNEW";
SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE);
{
//access your preferences here
}

SharedPreferences preferences_new = getSharedPreferences(PREF_FILE_NAME_NEW, MODE_PRIVATE);

{
//access your preferences_new here
}

Hope it helps.
