Easy view holder for android

A simple library to use view holders with less boilerplate.

Embed via Gradle

Add the repository

repositories {
    // ...
    maven { url 'https://jitpack.io' }
    // ...
}

Add the dependency

dependencies {
    // ...
    compile 'com.github.michiruf:android-easyviewholder:0.2'
    // ...
}

How to use ListView Adapter

Initialize the adapter

HolderArrayAdapter<Item> adapter = new HolderArrayAdapter<Item>(getActivity(), R.layout.your_item_layout) {
    @Override
    protected ViewHolder<Item> constructHolder(View view) {
        return new ItemHolder(view);
    }
};
listView.setAdapter(adapter);

Build your holder implementing the ViewHolder interface

protected class ItemHolder implements HolderArrayAdapter.ViewHolder<Item> {

    protected TextView textView;

    public ItemHolder(View view) {
        // Find the views and bind them to the fields
    }

    @Override
    public void apply(Item item, int position) {
        // Apply your changes. For example:
        textView.setText(item.getName());
    }
}

Jow to use RecyclerView Adapter

Initialize the adapter

RecyclerHolderArrayAdapter<Item> adapter = new RecyclerHolderArrayAdapter<Item>(R.layout.your_item_layout) {
    @Override
    protected ViewHolder<Item> constructHolder(View view) {
        return new ItemHolder(view);
    }
};
recyclerView.setAdapter(adapter);

Build your holder extending RecyclerHolderArrayAdapter.ViewHolder class

class ItemHolder extends RecyclerHolderArrayAdapter.ViewHolder<Item> {

    protected TextView textView;

    ItemHolder(View view) {
        super(view);
        // Find the views and bind them to the fields
    }

    @Override
    public void apply(Item item, int position) {
        // Apply your changes. For example:
        textView.setText(item.getName());
    }
}

UPDATE: Since the RecyclerView does not support OnItemClickListeners v0.5 will support this.
