Question

I have some Shared Preferences in my application defined in an XML file. They are EditTextPreferences. I want to display the existing values on the Preference screen so that the user doesn’t have to enter the Preference Edit Dialog to see the current value of the Preference. The defaultValue is only visible in the Dialog screen. I want to see the defaultValue in the main preferences screen – maybe in the place of android:summary. How can I do this?

<EditTextPreference
  android:key="PREF_LT_500"
  android:title="Step 1"
  android:summary="I dont want a summary - I want to show current value"
  android:inputType="numberDecimal" 
  android:defaultValue="0.8952"
  android:dialogTitle="Enter Blah " />

Thanks in advance

Answer 1

You could try:

yourPrefrence.getText();

Or a more generic solution:

SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(this);

String ans = p.getString(keyStr, defaultValue);

When this is a Context, keyStr is the key & defaultValue is a default value in case the key is not found (usually “”)
