SearchPreference

This is a library for Android apps that allows to search inside Preference xml files. The library provides a subclass of Preference that can be integrated into existing apps easily.

Adding to your app

Add PreferenceSearch to your app/build.gradle:

dependencies {
    implementation 'com.github.ByteHamster:SearchPreference:v1.0.3'
}

Add PreferenceSearch to your build.gradle:

allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

Add search bar to your preferences.xml file:

<com.bytehamster.lib.preferencesearch.SearchPreference
    android:key="searchPreference" />

Define search index in your PreferenceFragment:

public static class PrefsFragment extends PreferenceFragmentCompat {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);

        SearchPreference searchPreference = (SearchPreference) findPreference("searchPreference");
        SearchConfiguration config = searchPreference.getSearchConfiguration();
        config.setActivity((AppCompatActivity) getActivity());
        config.index(R.xml.preferences);
    }
}

And react to search results in your Activity:

public class MyActivity extends AppCompatActivity implements SearchPreferenceResultListener {
    private PrefsFragment prefsFragment;

    @Override
    public void onSearchResultClicked(SearchPreferenceResult result) {
        result.closeSearchPage(this);
        result.highlight(prefsFragment);
    }
}
