#SearchView with Realm DB results list ####Powered by

The RealmSearchView extends Android's SearchView widget. This is an much simpler and more versatile approach than Thorbenprimke's original RealmSearchView which implements a wrapper around a EditText and RealmRecyclerView. It's built on top of RealmRecyclerView and RealmBasedRecyclerViewAdapter.

It's easily customizable via layout attributes and adapter parameters.

##Example

##How to include in your project:

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the following dependencies to your module build.gradle:

	dependencies {
	        compile 'com.github.lnsd:RealmSearchView:v0.1.0'
	        
	      	compile 'com.github.thorbenprimke:realm-recyclerview:0.9.19'
	        compile 'com.github.thorbenprimke:realm-searchview:0.9.6'
	}

This library requires thorbenprimke's RealmRecyclerView and RealmSearchViewAdapter classes.

##How to get started:

The RealmSearchView extends Android's SearchView widget. The RealmSearchAdapter has added functionality for the filtering of the Realm. The snippet below shows how to include the RealmSearchView in your layout file.

    <es.lnsd.realmsearchview.RealmSearchView
        android:id="@+id/search_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:rsvHint="@string/search_hint"
        />

A RealmRecyclerView is required to show the results list.

    <co.moonmonkeylabs.realmrecyclerview.RealmRecyclerView
            android:id="@+id/realm_recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            app:rrvLayoutType="LinearLayout"
            app:rrvEmptyLayoutId="@layout/empty_view" />

The associateRealmRecyclerView() method MUST be called before calling the setAdapter(). Like here.

    @Bind(R.id.search_view) RealmSearchView searchView;
    @Bind(R.id.realm_recycler_view) RealmRecyclerView recyclerView;

	@Override
    protected void onCreate(Bundle savedInstanceState) {
    	...
        searchView.associateRealmRecyclerView(recyclerView);
        searchView.setAdapter(adapter);
    }

##The RealmSearchView attributes:

• rsvHint: This is the search box hint. It a string reference.

##RealmSearchAdapter

The adapter does all the filtering. The following list of parameters are available to customize the filtering.

• filterKey: The filterKey is required as it is the columnName that the results are filtered by.

• useContains: If true, uses contains, otherwise uses beginsWith.

• useCaseSensitive: If true, ensures that the filter is respecting casing. If false, ignores any casing.

• sortAscending: If true, ascending, otherwise descending.

• sortKey: The columnName by which the results should be sorted.

• basePredicate: The basePredicate is used to filter the results whenever the searchBar is empty.

The RealmSearchAdapter has two constructors. One that only takes the filterKey parameter and one that takes all parameters. In addition, the adapter has to be provided with a valid instance of Realm. It is used throughout the life of view to requery the results.

##Work in progress! This library is currently under develpment. I would love to hear your feedback. Do you find the RealmSearchView useful? What functionality are you missing? Open a Github issue and let me know. Thanks!
