#SimpleItemDecoration

Currently in active development

SimpleItemDecoration is a simple library for adding dividers and offsets to Android's RecyclerView using RecyclerView.ItemDecoration.

It can be used to add both interior dividers and start/end offsets to RecyclerViews using LinearLayoutManager or GridLayoutManager.

###Usage

All of the ItemDecorations included can be added to your RecyclerView by calling RecyclerView#addItemDecoration(), passing in your desired ItemDecoration as a parameter.

####DividerItemDecoration

DividerItemDecoration is used to add interior dividers to a RecyclerView using a LinearLayoutManager.

Its constructor takes in your preferred divider as a Drawable.

Drawable dividerDrawable = ContextCompat.getDrawable(this, R.drawable.divider_sample);

recyclerView.addItemDecoration(new DividerItemDecoration(dividerDrawable));

####StartOffsetItemDecoration

StartOffsetItemDecoration is used to add an offset to the start of a RecyclerView using a LinearLayoutManager. If the RecyclerView is oriented vertically, the offset will be added to the top of the RecyclerView. If the RecyclerView is oriented horizontally, the offset will be added to the lefthand side of the RecyclerView.

Its constructor takes in your preferred offset in pixels.

int offsetPx = 10;

recyclerView.addItemDecoration(new StartOffsetItemDecoration(offsetPx));

####EndOffsetItemDecoration

EndOffsetItemDecoration is used to add an offset to the end of a RecyclerView using a LinearLayoutManager. If the RecyclerView is oriented vertically, the offset will be added to the bottom of the RecyclerView. If the RecyclerView is oriented horizontally, the offset will be added to the righthand side of the RecyclerView.

Its constructor takes in your preferred offset in pixels.

int offsetPx = 10;

recyclerView.addItemDecoration(new EndOffsetItemDecoration(offsetPx));

####GridDividerItemDecoration

GridDividerItemDecoration is used to add interior dividers to a RecyclerView using a GridLayoutManager.

Its constructor takes in your preferred horizontal and vertical dividers, along with the number of columns in the grid.

Drawable horizontalDividerDrawable = ContextCompat.getDrawable(this, R.drawable.divider_horizontal);
Drawable verticalDividerDrawable = ContextCompat.getDrawable(this, R.drawable.divider_vertical);
int numColumns = 2;

recyclerView.addItemDecoration(new GridDividerItemDecoration(horizontalDividerDrawable, verticalDividerDrawable, numColumns));

####GridTopOffsetItemDecoration

GridTopOffsetItemDecoration is used to add an offset to the top of a RecyclerView using a GridLayoutManager.

Its constructor takes in your preferred offset in pixels and the number of columns in the grid.

int offsetPx = 10;
int numColumns = 2;

recyclerView.addItemDecoration(new GridTopOffsetItemDecoration(offsetPx, numColumns));

####GridBottomOffsetItemDecoration

GridBottomOffsetItemDecoration is used to add an offset to the bottom of a RecyclerView using a GridLayoutManager.

Its constructor takes in your preferred offset in pixels and the number of columns in the grid.

int offsetPx = 10;
int numColumns = 2;

recyclerView.addItemDecoration(new GridBottomOffsetItemDecoration(offsetPx, numColumns));
