##Requirements
- Android SDK 16+
##Usage
Add to your root build.gradle:
allprojects{repositories{... maven{url "https://jitpack.io" } } }Add the dependency:
dependencies{compile 'com.github.yalantis:todolist:v1.0.1' }Add BatRecyclerView to your xml layout
<?xml version="1.0" encoding="utf-8"?> <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:id="@+id/root"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/gradient"android:orientation="vertical"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar"android:layout_width="match_parent"android:layout_height="?android:attr/actionBarSize"android:background="@android:color/transparent"app:logo="@drawable/ic_menu"> <TextViewandroid:id="@+id/text_title"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"android:text="14 Feb, 2016"android:textColor="@android:color/white"android:textSize="20sp" /> </android.support.v7.widget.Toolbar> <com.yalantis.beamazingtoday.ui.widget.BatRecyclerView android:id="@+id/bat_recycler_view"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_gravity="center_horizontal"app:add_button_color="@drawable/selector_button_add"app:hint="@string/str_add_goal"app:radio_button_res="@drawable/selector_radio_button" /> </LinearLayout>Create BatListener
privateBatListenermListener = newBatListener(){@Overridepublicvoidadd(Stringstring){mGoals.add(0, newGoal(string)); mAdapter.notify(AnimationType.ADD, 0)} @Overridepublicvoiddelete(intposition){mGoals.remove(position); mAdapter.notify(AnimationType.REMOVE, position)} @Overridepublicvoidmove(intfrom, intto){if (from >= 0 && to >= 0){//if you use 'BatItemAnimator'mAnimator.setPosition(to); BatModelmodel = mGoals.get(from); mGoals.remove(model); mGoals.add(to, model); mAdapter.notify(AnimationType.MOVE, from, to); if (from == 0 || to == 0){mRecyclerView.getView().scrollToPosition(Math.min(from, to))} } } };Create BatAdapter. Pass to its constructor list of models and BatListener. Note that your model should implement BatModel interface
mAdapter = newBatAdapter(mGoals = newArrayList<BatModel>(){{add(newGoal("first")); add(newGoal("second")); add(newGoal("third")); add(newGoal("fourth")); add(newGoal("fifth")); add(newGoal("sixth")); add(newGoal("seventh")); add(newGoal("eighth")); add(newGoal("ninth")); add(newGoal("tenth"))}}, mListener); mAdapter.setOnItemClickListener(newOnItemClickListener(){@OverridepublicvoidonClick(BatModelitem, intposition){Toast.makeText(ExampleActivity.this, item.getText(), Toast.LENGTH_SHORT).show()} });Initialize your recycler view
mRecyclerView.getView().setLayoutManager(newLinearLayoutManager(this)); mRecyclerView.getView().setAdapter(mAdapter); ItemTouchHelperitemTouchHelper = newItemTouchHelper(newBatCallback(this)); itemTouchHelper.attachToRecyclerView(mRecyclerView.getView()); mRecyclerView.setAddItemListener(mListener);You can use BatItemAnimator to animate list items just like in our demo:
mAnimator = newBatItemAnimator(); mAdapter = newBatAdapter(mGoals = newArrayList<BatModel>(){{add(newGoal("first")); add(newGoal("second")); add(newGoal("third")); add(newGoal("fourth")); add(newGoal("fifth")); add(newGoal("sixth")); add(newGoal("seventh")); add(newGoal("eighth")); add(newGoal("ninth")); add(newGoal("tenth"))}}, mListener, mAnimator); mRecyclerView.getView().setItemAnimator(mAnimator);You need to pass the animator instance to BatRecyclerView and to BatAdapter. Also it's necessary to pass the position of the moved item in move() callback:
@Overridepublicvoidmove(intfrom, intto){if (from >= 0 && to >= 0){mAnimator.setPosition(to); BatModelmodel = mGoals.get(from); mGoals.remove(model); mGoals.add(to, model); mAdapter.notify(AnimationType.MOVE, from, to); if (from == 0 || to == 0){mRecyclerView.getView().scrollToPosition(Math.min(from, to))} } }For more usage examples please review sample app
- Cursor fixed.
cursor_drawableattribute andsetCursorDrawable(@DrawableRes int res)method added. Should be used instead ofcursor_colorattribute andsetCursorColor(@ColorInt int color)method respectively
We’d be really happy if you could send us links to your projects where you use our component. Just send an email to [email protected] And do let us know if you have any questions or suggestion regarding the animation.
P.S. We’re going to publish more awesomeness wrapped in code and a tutorial on how to make UI for iOS (Android) better than better. Stay tuned!
