The main idea was to avoid empty/error/items view code duplication among views but will cut a lot of things from your control. In practice is not a good idea.
This is an attempt to make RecyclerView easier to use.
Features built in:
- ProgressBar while adapter hasn't been set
- EmptyView if adapter is empty
- SwipeRefreshLayout (Google's one)
- Infinite scrolling, when you reach the X last item, load more of them.
- Swipe To Dismiss or Swipe To Remove
- Sticky headers (via Eowise, see sample)
Please check CHANGELOG for updates.
To publish:
./gradlew clean build generateRelease
##Integration GRADLE
dependencies {
compile 'com.barista_v:ultrarecyclerview:<version>'
}
##Usage
- Use directly UltraRecyclerView:
<com.barista_v.ultrarecyclerview.UltraRecyclerView
android:id="@+id/list"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_empty="@layout/emptyview"
app:layout_moreProgress="@layout/view_more_progress"
app:mainLayoutId="@layout/layout_recyclerview_verticalscroll"
app:recyclerClipToPadding="false"
app:recyclerPadding="16dp"
app:scrollbarStyle="insideInset"/>
- Current Attributes supported:
<attr name="layout_empty" format="reference"/>
<attr name="layout_moreProgress" format="reference"/>
<attr name="layout_progress" format="reference"/>
<attr name="recyclerClipToPadding" format="boolean"/>
<attr name="recyclerPadding" format="dimension"/>
<attr name="recyclerPaddingTop" format="dimension"/>
<attr name="recyclerPaddingBottom" format="dimension"/>
<attr name="recyclerPaddingLeft" format="dimension"/>
<attr name="recyclerPaddingRight" format="dimension"/>
<attr name="scrollbarStyle">
<flag name="insideOverlay" value="0x0"/>
<flag name="insideInset" value="0x01000000"/>
<flag name="outsideOverlay" value="0x02000000"/>
<flag name="outsideInset" value="0x03000000"/>
</attr>
<attr name="mainLayoutId" format="reference"/>
##UltraRecyclerView Java Usage
recycler.setRefreshListener(new SwipeRefreshLayout.OnRefreshListener {
@Override
public void onRefresh() {
// Do your refresh
});
// when there is only 10 items to see in the recycler, this is triggered
recycler.setupMoreListener(new OnMoreListener() {
@Override
public void onMoreAsked(int numberOfItems, int numberBeforeMore, int currentItemPos) {
// Fetch more from Api or DB
}}, 10);
recycler.setupSwipeToDismiss(new SwipeDismissListViewTouchListener.DismissCallbacks() {
@Override
public boolean canDismiss(int position) {
return true
}
@Override
public void onDismiss(RecyclerView recyclerView, int[] reverseSortedPositions) {
// Do your stuff like call an Api or update your db
}});
##Scrollbars
RecyclerView currently doesn't support setting scrollbars from code that's why I can't parse custom attributes.
You have to use appropriate mainLayoutId
attribute to have scrollbars visible.
<com.barista_v.ultrarecyclerview.UltraRecyclerView
app:mainLayoutId="@layout/layout_recyclerview_verticalscroll"
app:scrollbarStyle="insideInset"
.../>
<com.barista_v.ultrarecyclerview.UltraRecyclerView
app:mainLayoutId="@layout/layout_recyclerview_horizontalscroll"
app:scrollbarStyle="insideInset"
.../>
##Swipe layout
-
You should always assign
android:id
to@id/recyclerview_swipe
. Note that it's a reference to an already defined id, so don't use@+id
-
The
SwipeLayout
can only have 2 children that are instances ofViewGroup
, e.g.LinearLayout
,RelativeLayout
,GridLayout
-
The first child is the bottom view, the second child is the top view
-
Your adapter should extend
BaseSwipeAdapter
class -
Do not setup swipe to dismiss and use swipe layout at the same time. If you do - a kitten will cry somewhere.
Item example:
<com.barista_v.ultrarecyclerview.swipe.SwipeLayout
android:id="@id/recyclerview_swipe"
xmlns:swipe="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
swipe:horizontalSwipeOffset="16dp">
<LinearLayout
...
</LinearLayout>
<LinearLayout
...
</LinearLayout>
</com.barista_v.ultrarecyclerview.swipe.SwipeLayout>
Custom attributes supported:
<attr name="drag_edge" format="enum">
<enum name="left" value="0"/>
<enum name="right" value="1"/>
<enum name="top" value="2"/>
<enum name="bottom" value="3"/>
</attr>
<attr name="horizontalSwipeOffset" format="dimension"/>
<attr name="verticalSwipeOffset" format="dimension"/>
<attr name="show_mode" format="enum">
<enum name="lay_down" value="0"/>
<enum name="pull_out" value="1"/>
</attr>
