EasyAdapter
v2.0.5
RecyclerView は主に Android プロジェクトで Android ウィジェットとして使用されます。そのためには、ビューの項目を提供するアダプターを実装する必要があります。ほとんどの場合、同じ基本ロジックが必要ですが、すべてを何度も何度も記述する必要があります。そこで、ここにその解決策を示します。
アプリ > build.gradle
implementation ' com.github.mkrupal09:EasyAdapter:v2.0.5 'root > build.gradle、すべてのプロジェクト > リポジトリに jitpack.io Maven URL を追加します
allprojects {
repositories {
.. .
maven { url ' https://jitpack.io ' }
}
}アプリの build.gradle 内に buildFunction ブロックを追加し (そうでない場合)、下記のように dataBinding フラグを追加します。
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()
}
}EasyAdapter を使用できる EasySpinner を作成しました
ArrayAdapter や CustomArrayAdapter を記述する必要はなく、EasyAdapter の多くの機能を利用できます。
< 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 " />
アダプターを EasySpinner に設定する
binding.easyspinner.setAdapter(adapter)を使用すると、スピナーをオートコンプリートテキストビューとして使用できます
binding.easyspinner.enableAutoCompleteMode { easySpinner, text ->
adapter.performFilter(text, filter)
}
以上です...スピナーアダプターが完成します。
レイアウトのプレビューには tools 属性を使用するため、常にアプリケーションを実行する必要はありません
リサイクルショップビュー
tools:listitem="@layout/inflater_category"
tools:itemCount="5"
tools:orientation="horizontal"
app:layoutManager="android.support.v7.widget.GridLayoutManager"
レイアウト
tools:text="Sample Text"
tools:visibility="VISIBLE"
tools:background="@color/colorPrimary"アンドロイドの事前定義サンプルデータ
tools:text="@tools:sample/cities,first_names,us_phones,lorem,lorem/random"
tools:background="@tools:sample/backgrounds/scenic"
tools:src="@tools/avatars"カスタムサンプルデータ
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" 変更履歴
