Usage

In your build.gradle file:

dependencies {
    compile 'com.felipecsl.asymmetricgridview:library:1.1.0'
}

In your layout xml:

<com.felipecsl.asymmetricgridview.library.widget.AsymmetricGridView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

In your activity class:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView = (AsymmetricGridView) findViewById(R.id.listView);

    // Choose your own preferred column width
    listView.setRequestedColumnWidth(Utils.dpToPx(this, 120));
    final List<AsymmetricItem> items = new ArrayList<>();

    // initialize your items array
    adapter = new ListAdapter(this, listView, items);

    listView.setAdapter(adapter);
}

Supports resetting and appending more elements into the adapter:

// Will append more items at the end of the adapter.
listView.getAdapter().appendItems(moreItems);

// resetting the adapter items. Will clear the adapter
// and add the new items.
listView.getAdapter().setItems(items);

Toggle to enable/disable reordering of elements to better fill the grid

// Setting to true will move items up and down to better use the space
// Defaults to false.
listView.setAllowReordering(true);

listView.isAllowReordering(); // true

Works with Android 2.3.x and above.
