CymChad/BaserecyclerViewAdapterhelper framework
CymChad/BaserecyclerViewAdapterhelper framework
1 Overview
CymChad/BaserecyclerViewAdapterhelper (hereinafter referred to as Brvah) is an open source library used to simplify the use of RecyclerView in Android.It provides some commonly used functions and methods to make developers more conveniently operate and manage RecyclerView.
2. Installation
Use the BRVAH library in your Android project, you need to add the following dependencies to the project's Build.gradle file:
gradle
implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:3.0.4'
3. Configuration
The configuration of the BRVAH library is divided into two steps: layout configuration and adapter configuration.
-Layout configuration
First, add the RecyclerView control to your layout file:
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Create a Item layout file to define the style of the column item.For example, create a layout file called "item_layout.xml"::
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Item Text" />
</LinearLayout>
-The adapter configuration
In your Activity or Fragment, create a adapter class to manage data and views of RecyclerView.First, create a viewholder class to save the view of the list item and bind the data:
public class MyViewHolder extends BaseViewHolder {
public MyViewHolder(View view) {
super(view);
}
public void bindData(String item) {
TextView textView = getView(R.id.textView);
textView.setText(item);
}
}
Then, create a adapter class, inherit the Basequickadapter, and rewrite the corresponding method:
public class MyAdapter extends BaseQuickAdapter<String, MyViewHolder> {
public MyAdapter(List<String> data) {
super(R.layout.item_layout, data);
}
@Override
protected void convert(MyViewHolder viewHolder, String item) {
viewHolder.bindData(item);
}
}
Finally, set up RecyclerView and adapter in your Activity or Fragment:
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
MyAdapter Adapter = New MyAdapter (Data); // Data is a list of data
recyclerView.setAdapter(adapter);
4. Use
After completing the installation and configuration, you can use the BRVAH library through the following steps:
- adding data
adapter.addData("New Item");
- delete data
adapter.remove (2); // Delete the item with the index of 2
- update data
adapter.setdata (1, "updated item"); // Update indexes 1
-Click on the event
adapter.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
// Treat the click event
}
});
For more functions and methods, please refer to the official documentation of BRVAH.
Through the above installation and configuration steps, you can successfully use CymChad/BaserecyclerViewAdapterhelper framework to simplify the use of RecyclerView, improve development efficiency, and achieve some common functions.I hope this article can help you.
