EasyAdapter Based on Android Data Binding
RecyclerView is mostly used android widgets in the Android Project, for that you have to implement an Adapter which provides the items for the view. In most cases it require the same base logic, but require you to write everything again and again.so here is sollution for it.
- Reduce Boilerplate code to create adapter and holder.
- you can filter adapter without coding much.
- You wil have load more feature with progress bar at bottom.
- includes swipe to action.
- includes View Events callbacks (ClickEvent,CheckChangeEvent)
- and many more..
app > build.gradle
implementation 'com.github.mkrupal09:EasyAdapter:v2.0.5'root > build.gradle, add jitpack.io maven url in allprojects>repositories
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}inside app build.gradle add buildFeatures block(if not) and add dataBinding flag as mentioned below
android {
buildFeatures {
dataBinding true
}
}adapter = new EasyAdapter<Category, InflaterCategoryBinding>(R.layout.inflater_category) {
@Override
public void onBind(@NonNull InflaterCategoryBinding binding, @NonNull Category model) {
binding.tvName.setText(model.name);
}
}
class CategoryAdapter() :EasyAdapter<Category, InflaterCategoryBinding>(R.layout.inflater_category) {
override fun onBind(binding: InflaterCategoryBinding, model: Category) {
binding.apply {
tvName.text = model.name
cbCategory.isChecked = model.isSelected
}
}
}###java
public CategoryAdapter() {
super(R.layout.inflater_category);
}
@Override
public void onBind(@NonNull InflaterCategoryBinding binding, @NonNull Category model) {
binding.tvName.setText(model.name);
}//Override in Adapter
override fun onCreatingHolder(binding: InflaterCategoryBinding, easyHolder: EasyHolder) {
super.onCreatingHolder(binding, easyHolder)
binding.root.setOnClickListener(easyHolder.clickListener)
}adapter.setRecyclerViewItemClick { itemView, model ->
//Perform Operation here
}adapter.performFilter(newText,filter)
val filter= object : EasyAdapter.OnFilter<Category> {
override fun onFilterApply(filter: Any, model: Category): Boolean {
return model.name.toLowerCase().contains(filter.toString().toLowerCase())
}
override fun onFilterResult(filteredList: ArrayList<Category>?) {
adapter.clear(false)
adapter.addAll(filteredList, false)
adapter.notifyDataSetChanged()
}
}
adapter.setLoadMoreRes(R.layout.layout_progress)
adapter.setOnLoadMoreListener(binding.recyclerView, EasyAdapter.OnLoadMoreListener {
if (paging != -1) {
requestLoadMore() //Your Method
return@OnLoadMoreListener true // Returns True if you have more data
}
return@OnLoadMoreListener false // Return false if you don't have more data
})
adapter.enableSwipeAction(binding.recyclerView)override fun onCreatingHolder(binding: InflaterCategoryBinding, easyHolder: EasyHolder) {
binding.llDelete.post {
easyHolder.setEnableSwipeToDelete(binding.llCategory, 0, binding.llDelete.measuredWidth)
}
}
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
//Swipe Reveal Layout
<LinearLayout
android:id="@+id/llDelete"
android:padding="10dp"
android:layout_gravity="end"
android:background="@android:color/holo_red_dark"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@android:drawable/ic_input_delete" />
</LinearLayout>
//Your container
<LinearLayout
android:background="@android:color/white"
android:id="@+id/llCategory"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="horizontal"
android:padding="5dp"/>
</FrameLayout>adapter.setOnDataUpdateListener {
if (it.size <= 0) {
Toast.makeText(this@MainActivity, "No Data Found", Toast.LENGTH_SHORT).show()
}
}We've Created EasySpinner where you can use your EasyAdapter
No need to write ArrayAdapter or CustomArrayAdapter and you'll have lots of features from EasyAdapter.
<easyadapter.dc.com.library.EasySpinner
android:background="@drawable/rect_background"
android:id="@+id/easyspinner"
android:layout_width="220dp"
android:layout_height="wrap_content"
android:textColor="@android:color/black"
android:drawableRight="@android:drawable/arrow_down_float"
android:textColorHint="@android:color/black"
android:padding="10dp"
android:hint="Select Name" />
Setting adapter to EasySpinner
binding.easyspinner.setAdapter(adapter)you can use spinner as autocomplete textview by using
binding.easyspinner.enableAutoCompleteMode { easySpinner, text ->
adapter.performFilter(text, filter)
}
That's it... you will have spinner adapter.
Use tools attribute for previewing Layout, so you don't need to always run application
recyclerview
tools:listitem="@layout/inflater_category"
tools:itemCount="5"
tools:orientation="horizontal"
app:layoutManager="android.support.v7.widget.GridLayoutManager"
layout
tools:text="Sample Text"
tools:visibility="VISIBLE"
tools:background="@color/colorPrimary"android predefine sample data
tools:text="@tools:sample/cities,first_names,us_phones,lorem,lorem/random"
tools:background="@tools:sample/backgrounds/scenic"
tools:src="@tools/avatars"custom sample data
To create your fake/sample data folder,
just right click on the “app” folder then “new > Sample Data directory” <br />
create new file with "filename" and write each text by new lines
file contains -
Georgia <br />
Illinois <br />
Paris <br />
London <br />
so it will randomly pick names and display in layout by
tools:text="@sample/filename" https://github.com/alex-townsend/SwipeOpenItemTouchHelper
without this person cannot achieve swipe action in recyclerview
