More details here: http://android-developers.blogspot.se/2016/02/android-support-library-232.html 5 | 6 | ## Description 7 | Implementation of [LinearLayoutManager](https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager.html) which wraps its contents. 8 | 9 | Usage example: 10 | 
final LinearLayoutManager layoutManager = new org.solovyev.android.views.llm.LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
11 | final RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
12 | recyclerView.setLayoutManager(layoutManager);
13 | recyclerView.addItemDecoration(new DividerItemDecoration(this, null));
14 | recyclerView.setAdapter(adapter);
15 | 16 | Note that if the child views in your RecyclerView have the fixed size LinearLayoutManager#setChildSize should be used 17 | to avoid unnecessary measuring. 18 | 19 | ## Installation 20 | Gradle dependency: 21 | 
compile 'org.solovyev.android.views:linear-layout-manager:0.5@aar'
22 | Maven dependency: 23 | ```xml 24 | 25 | org.solovyev.android.views 26 | linear-layout-manager 27 | 0.5 28 | apklib 29 | 30 | ``` 31 | 32 | ## License 33 | Library is distributed under Apache 2.0
