RecyclerView万能的Adapter

RecyclerView万能的Adapter

如果使用了Data Binding Library框架,并使用了RecyclerView.可以使用这个Adapter

不用在为每一个不同的布局写单独的Adapter

功能

添加HeaderView和FooterView

Item的Click事件处理

也可以添加额外的逻辑处理

使用

RecyclerView.setAdapter

item.xml

<?xml version="1.0" encoding="utf-8"?>
<layout>

<data>
<import type="android.view.View"/>
<variable
name="yourVariable"
type="yourpacket.mode.XXX"/>

</data>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
.....................
android:text="@{yourVariable.xxx}"
.....................
>
</LinearLayout>

</layout>

DataBindingRecyclerViewAdapter adapter = new DataBindingRecyclerViewAdapter
(mContext,R.layout.item,BR.yourVariable,variableList);
mRecyclerView.setAdapter(adapter);

setOnItemClick

adapter.setOnItemCkickListener(new DataBindingRecyclerViewAdapter.ItemClickListener(){
@Override
public void itemClick(View view, int position) {
//..................
}
});

addHeader And addFooter

mRecyclerView.setAdapter(adapter);
.....
LayoutInflater inflater = LayoutInflater.from(getContext());
View footerView = inflater.inflate(R.layout.recycler_view_load_more,binding.recyclerView,false);
adapter.addFooterView(footerView);
adapter.notifyDataSetChanged();

LayoutInflater inflater = LayoutInflater.from(getContext());
View footerView = inflater.inflate(R.layout.recycler_view_load_more,binding.recyclerView,false);
adapter.addFooterView(footerView);
mRecyclerView.setAdapter(adapter);

额外的逻辑处理

如果只给item添加一个variable还不够的话可以另外添加

adapter.setOnBindingViewHolderListener(new DataBindingRecyclerViewAdapter.OnBindingViewHolderListener() {
@Override
public void onHolderBinding(DataBindingRecyclerViewAdapter.DataBindingViewHolder holder, int position) {
ViewDataBinding binding = DataBindingUtil.getBinding(holder.itemView);
binding.setVariable(BR.presenter,new MyPresenter());

}
});

item.xml

<?xml version="1.0" encoding="utf-8"?>
<layout>

<data>
<import type="android.view.View"/>
<variable
name="yourVariable"
type="yourpacket.mode.XXX"/>
<variable
name="presenter"
type="yourpacket.MyPresenter"/>
</data>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView
.....................
android:text="@{yourVariable.xxx}"
.....................
>
<Button
android:id="@+id/txtEdit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="@{userCode.equals(story.createUCode)?View.VISIBLE:View.GONE}"
android:onClick="@{(view)->presenter.edit(view,yourVariable)}"
android:text="EDIT"/>
<Button
android:id="@+id/txtDelete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="@{userCode.equals(story.createUCode)?View.VISIBLE:View.GONE}"
android:onClick="@{(view) -> presenter.delete(view,yourVariable)}"
android:text="DELETE"/>

</LinearLayout>

</layout>
