AutoDroid automates some common Android development tasks

1. RecyclerView

RecylerView is awesome, but it require you to create several boilerplate code just to make it work – such as

  1. Create an Adapter class
  2. Create a ViewHolder class
  3. Declare and initialize the ViewHolder with all the views
  4. Implement Adapter methods such as
    1. onCreateViewHolder
    2. onBindViewHolder - Bind each of the views in ViewHolder with the data

In Code it looks something like -

    override fun onCreate(savedInstanceState: Bundle?) {
        viewManager = LinearLayoutManager(this)
        viewAdapter = MyAdapter(dataSet)
        recyclerView = findViewById<RecyclerView>( {
            layoutManager = viewManager

            adapter = viewAdapter

 * Adapter for the recycler view
class MyAdapter(private val myDataset: MutableList<MyData>) : RecyclerView.Adapter<MyAdapter.ViewHolder>() {

    private var onClickListener: View.OnClickListener? = null;

     * View holder for recycler view
    class ViewHolder(mainView: View, private val onClickListener: View.OnClickListener) : RecyclerView.ViewHolder(mainView) {

         * Keep hold of the first name text view
        val firstName: TextView = mainView.findViewById(

         * Keep hold of the second name text view
        val secondName: TextView = mainView.findViewById(

         * Keep hold of the image view for image resource
        val imageResource: ImageView = mainView.findViewById(

         * Keep hold of the add button to add click listener
        val addBtn: Button = mainView.findViewById(

         * Keep hold of the remove button to add click listener
        val removeBtn: Button = mainView.findViewById(

        init {
            //add the click listeners
            addBtn.setOnClickListener { onClickListener.onClick(addBtn) }
            removeBtn.setOnClickListener { onClickListener.onClick(removeBtn) }

    fun setOnClickListener(onClickListener: View.OnClickListener) {
        this.onClickListener = onClickListener

     * Create the view holder
    override fun onCreateViewHolder(parent: ViewGroup,
                                    viewType: Int): MyAdapter.ViewHolder {
        return ViewHolder(LayoutInflater.from(parent.context)
                .inflate(R.layout.my_text_view, parent, false),
                View.OnClickListener {

     * Bind the view holder with the data
    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        //bind the first name with the data
        holder.firstName.text = myDataset[position].firstName

        //bind the second name with the data
        holder.secondName.text = myDataset[position].secondName

        //bind the image using picaso

    override fun getItemCount(): Int {
        return myDataset.size

With AutoDroid, all you have to do is :

//Set the adapter to the AutoDroid auto generated class
recyclerView.adapter = MyDataAdapter(Pager(listDataProvider))

To use AutoDroid, simply annotate your data class for the recycler as follows

@ItemLayoutRes(layoutID = R.layout.itemView)
data class MyData(@ItemIdRes(viewID = val firstName: String,
                  @ItemIdRes(viewID =, itemType = ItemType.IMAGE) val imageResource: Int)

AutoDroid will generate the Adapter for you (In this case MyDataAdapter). Simply set this as the adapter of your recycler view.

See example

That’s it!

Getting AutoDroid

    kapt 'com.josesamuel: autodroid:1.0.0'
    implementation 'com.josesamuel:pager:1.0.4'
    //Add Picaso if the any data binding uses Image type
    implementation 'com.squareup.picasso:picasso:2.71828'
