Question

I need to launch new Activity from PreferenceActivity on button click or somehow else. Is it possible? How to make it?

Answer 1

You can start another Activity from your PreferenceActivity like the standard way of doing that. For example:

Intent testIntent = new Intent(getApplicationContext(), Activity2.class);
startActivity(testIntent);

First, define a Preference in your XML:

<Preference
    android:key="test_pref"
    android:summary="@string/someDescription"
    android:title="Some Random Title" >
</Preference>

In your PreferenceActivity:

Preference pref = findPreference("test_pref");
shareSociallyYou.setOnPreferenceClickListener(new OnPreferenceClickListener() {

    @Override
    public boolean onPreferenceClick(Preference preference) {

        Intent testIntent = new Intent(getApplicationContext(), Activity2.class);
        startActivity(testIntent);

        return true;
    }
});
