Simple Android RecyclerView example

Question

I\'ve made a list of items a few times using Android\'s RecyclerView, but it is a rather complicated process. Going through one of the numerous tutorials online

Answer 1

Based on different sources I have created Simple Implementation of RecyclerView using a Simple Library.

Add this line in build.gradle

implementation 'com.hereshem.lib:awesomelib:2.0.1'

AddCreate a RecyclerView by adding MyRecyclerView in activity_main.xml with

Now in the MainActivity, Create a ViewHolder by passing the name of Class that needs to bind

public static class EVHolder extends MyViewHolder {
    TextView date, title, summary;
    public EVHolder(View v) {
        super(v);
        date = v.findViewById(R.id.date);
        title = v.findViewById(R.id.title);
        summary = v.findViewById(R.id.summary);
    }
    @Override
    public void bindView(Events c) {
        date.setText(c.date);
        title.setText(c.title);
        summary.setText(c.summary);
    }
}

Create Items list variable and adapters with very few lines by passing items, class and layout in the adapter

List items = new ArrayList<>();
MyRecyclerView recycler = findViewById(R.id.recycler);
RecyclerViewAdapter adapter = new RecyclerViewAdapter(this, items, EVHolder.class, R.layout.row_event);
recycler.setAdapter(adapter);

ClickListener can be added with following lines

recycler.setOnItemClickListener(new MyRecyclerView.OnItemClickListener() {
    @Override
    public void onItemClick(int position) {
        Toast.makeText(MainActivity.this, "Recycler Item Clicked " + position, Toast.LENGTH_SHORT).show();
    }
});

Its all done.

More example and implementation can be found here . Hope this helps !!!
