How do I call a specific PreferenceFragment from a PreferenceActivity?

Question

I have a PreferenceActivity with several fragments:

R.xml.preferences: (shortened for better readability):

Answer 1

According to: http://developer.android.com/reference/android/preference/PreferenceActivity.html#EXTRA_SHOW_FRAGMENT

public static final String EXTRA_SHOW_FRAGMENT

Added in API level 11 When starting this activity, the invoking Intent can contain this extra string to specify which fragment should be initially displayed.

Constant Value: ":android:show_fragment"

intent = new Intent( this, SettingsActivity.class );
intent.putExtra( PreferenceActivity.EXTRA_SHOW_FRAGMENT, Fragment1.class.getName() );
intent.putExtra( PreferenceActivity.EXTRA_NO_HEADERS, true );
