*** ** * ** ***

LayoutParams used by GridLayoutManager.

Note that if the orientation is[VERTICAL](https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager#VERTICAL), the width parameter is ignored and if the orientation is[HORIZONTAL](https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager#HORIZONTAL)the height parameter is ignored because child view is expected to fill all of the space given to it.

## Public methods

### getSpanIndex

added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)  

```
int getSpanIndex ()
```

Returns the current span index of this View. If the View is not laid out yet, the return value is`undefined`.

Starting with RecyclerView**24.2.0** , span indices are always indexed from position 0 even if the layout is RTL. In a vertical GridLayoutManager,**leftmost** span is span 0 if the layout is**LTR** and**rightmost** span is span 0 if the layout is**RTL** . Prior to 24.2.0, it was the opposite which was conflicting with[getSpanIndex(int, int)](https://developer.android.com/reference/android/support/v7/widget/GridLayoutManager.SpanSizeLookup#getSpanIndex(int, int)).

If the View occupies multiple spans, span with the minimum index is returned.

<br />

|                  Returns                  ||
|-------|------------------------------------|
| `int` | The span index of the View. <br /> |

### getSpanSize

added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions)  

```
int getSpanSize ()
```

Returns the number of spans occupied by this View. If the View not laid out yet, the return value is`undefined`.

<br />

|                         Returns                          ||
|-------|---------------------------------------------------|
| `int` | The number of spans occupied by this View. <br /> |
