Installation

====

```groovy

dependencies {

    compile 'com.loopeer.library:itemtouchhelperextension:1.0.6'

}

```

Usages

====

```java

mCallback = new ItemTouchHelperCallback();

mItemTouchHelper = new ItemTouchHelperExtension(mCallback);

mItemTouchHelper.attachToRecyclerView(mRecyclerView);

```

ItemTouchHelperCallback just set as Itemtouchhelper. Set your swipe content view **translationX** by moving in method **onChildDraw**

```java

public class ItemTouchHelperCallback extends ItemTouchHelperExtension.Callback {

    @Override

    public int getMovementFlags(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder) {

        return makeMovementFlags(0, ItemTouchHelper.START);

    }

    @Override

    public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {

        return false;

    }

    

    ...

    @Override

    public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {

        MainRecyclerAdapter.ItemBaseViewHolder holder = (MainRecyclerAdapter.ItemBaseViewHolder) viewHolder;

        holder.mViewContent.setTranslationX(dX);

    }

}

```

At last you can let your **viewholder implements Extension** to set swipe settling width

```java

@Override

public float getActionWidth() {

    return mActionContainer.getWidth();

}

```

This will use whole recyclerview width when you do not add the width

Additional Drag Feature

====

If you want to add drag item feature.You just do **super.onChildDraw** in method onChildDraw of the class **ItemTouchHelperCallback**. Just like bottom:

```java

  @Override

    public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {

        if (dY != 0 && dX == 0) super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);

       ...

    }

```

Click Action Button To Close Opened

====

If you want to close item after click action btn in the swipe item. You show add

```java

    mItemTouchHelperExtension.closeOpened();

```
