An Android custom ListView that implements multiple columns and variable sized elements.

Please note that this is currently in a preview state. This basically means that the API is not fixed and you should expect changes between releases.

Try out the sample application on Google Play

In your build.gradle file:

repositories {
    maven { url 'https://raw.github.com/felipecsl/m2repository/master' }
    // ...
}

dependencies {
    // ...
    compile 'com.felipecsl:asymmetricgridview: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.

Currently only supports items with rowSpan = 2 and columnSpan = 2. In the near future it will support different layout configurations.

It will work best if you don't have too many items with different sizes. Ideally less than 20% of your items are of special sizes, otherwise the library may not find the best way to accommodate all the items without leaving a lot of empty space behind.

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
• Fork the project
• Start a feature/bugfix branch
• Commit and push until you are happy with your contribution
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
