Android DataBinding BaseClass 설계

Toolbar (using DataBinding) Example

ToolbarConfiguration

• BaseObservable를 활용해서 툴바 tiitle, image 값

public class ToolbarConfiguration extends BaseObservable {
    private String title;
    @DrawableRes
    private Integer imageDrawable;
    private View.OnClickListener listener;

    @Bindable
    public String getTitle() {
        return title;
    }

    @Bindable
    public Integer getImageDrawable() {
        return imageDrawable;
    }

    @Bindable
    public View.OnClickListener getListener() {
        return listener;
    }

    public void setConfiguration(String title, Integer imageDrawable, View.OnClickListener listener) {
        this.title = title;
        this.imageDrawable = imageDrawable;
        this.listener = listener;
        notifyChange();
    }
}

Base Toolbar layout (xml)

• 필요한 xml에 include 이용해서 사용

<?xml version="1.0" encoding="utf-8"?>
<layout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:bind="http://schemas.android.com/apk/res-auto">

    <data>
        <import type="android.view.View"/>

        <variable
                name="config"
                type="com.android.libbase.databinding.configurations.ToolbarConfiguration"/>
    </data>

    <com.hugocastelani.waterfalltoolbar.WaterfallToolbar
            android:id="@+id/waterfall_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize">

        <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@android:color/white">
            <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:textColor="@android:color/black"
                    android:visibility="@{config.title != null || !config.title.isEmpty() ? View.VISIBLE : View.GONE}"
                    android:text="@{config.title}"/>

            <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="end|center_vertical"
                    android:layout_marginEnd="10dp"
                    android:background="?android:attr/selectableItemBackgroundBorderless"
                    bind:imgRes="@{config.imageDrawable}"
                    bind:navigationOnClickListener="@{config.listener}"/>
        </androidx.appcompat.widget.Toolbar>

</layout>

BaseRecyclerview(using DataBinding) Example

Sample Adapter

• Multi View Type 처리 가능
• Endless scroll (load more)

public class GenericRVAdapterTest extends GenericRVAdapter<RVModel, OnRecyclerPositionClickListener> {

    private static final int NEW_TYPE = 4;

    GenericRVAdapterTest(Context context, OnRecyclerPositionClickListener listener) {
        super(context, listener);
    }

    @Override
    public int getItemViewType(int position) {
        if (getItem(position) != null && position % 3 == 0) {
            return NEW_TYPE;
        }
        return super.getItemViewType(position);
    }

    @Override
    protected int getItemLayout(int viewType) {
        if (viewType == NEW_TYPE) {
            return R.layout.rv_item2;
        }
        return R.layout.rv_item;
    }

    @Override
    public void onBindView(ViewDataBinding binding, ItemViewHolder viewHolder, RVModel item, int viewType, @Nullable OnRecyclerPositionClickListener listener) {
        AdapterModel model = (AdapterModel) item;

        if (viewType != NEW_TYPE) {
            RvItemBinding rvItemBinding = (RvItemBinding) binding;
            rvItemBinding.setItem(model);
        }
        else {
            RvItem2Binding rvItem2Binding = (RvItem2Binding) binding;
            rvItem2Binding.setItem(model);
        }
    }
}

MainAcitivy

  mainBinding.recyclerview.setLayoutManager(new LinearLayoutManager(this));
    GenericRVAdapterTest adapter = new GenericRVAdapterTest(getBaseContext(), null);
    adapter.addAll(getItems());
    mainBinding.recyclerview.setAdapter(adapter);

    mainBinding.recyclerview.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
        }
    });

private List<RVModel> getItems() {
