TableView using Recyclerview (Android)

A sample Android Studio Project showing using a Recyclerview as a Table View.

How the Height of Row works

The Height of row is determined by the cell, which has maximum multiline content. In this sample that cell is given wrap_content and other cells are given match_parent. I've got to find a way to dynamically check this later.

Upgraded to Kotlin (38% code reduction :))

(older java version can be found here

Here's the preview

Code Snippets

Here's the Recyclerview xml in the main layout.

<!-- Table View-->
<HorizontalScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent">

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerViewMovieList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:nestedScrollingEnabled="false"
    tools:listitem="@layout/table_list_item" />

</HorizontalScrollView>

Here's the Recyclerview Adapter onBinding (all other stuffs are the same)

Kotlin Version

val rowPos = holder.adapterPosition

if (rowPos == 0) {
    // Header Cells. Main Headings appear here
    holder.itemView.apply {
        setHeaderBg(txtMovieName)
        txtMovieName.text = "Name"
    }
} else {
    val modal = movieList[rowPos - 1]

    holder.itemView.apply {
        setContentBg(txtMovieName)
        txtMovieName.text = modal.movieName
    }
}

Click to see the example in Java.

@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
    RowViewHolder rowViewHolder = (RowViewHolder) holder;

    int rowPos = rowViewHolder.getAdapterPosition();

    if (rowPos == 0) {
        // Header Cells. Main Headings appear here
        rowViewHolder.txtRank.setBackgroundResource(R.drawable.table_header_cell_bg);
        rowViewHolder.txtMovieName.setBackgroundResource(R.drawable.table_header_cell_bg);
        rowViewHolder.txtYear.setBackgroundResource(R.drawable.table_header_cell_bg);
        rowViewHolder.txtCost.setBackgroundResource(R.drawable.table_header_cell_bg);

        rowViewHolder.txtRank.setText("Rank");
        rowViewHolder.txtMovieName.setText("Name");
        rowViewHolder.txtYear.setText("Year");
        rowViewHolder.txtCost.setText("Budget (in Millions)");
    } else {
        MovieModal modal = movieList.get(rowPos-1);

        // Content Cells. Content appear here
        rowViewHolder.txtRank.setBackgroundResource(R.drawable.table_content_cell_bg);
        rowViewHolder.txtMovieName.setBackgroundResource(R.drawable.table_content_cell_bg);
        rowViewHolder.txtYear.setBackgroundResource(R.drawable.table_content_cell_bg);
        rowViewHolder.txtCost.setBackgroundResource(R.drawable.table_content_cell_bg);

        rowViewHolder.txtRank.setText(modal.getRank()+"");
        rowViewHolder.txtMovieName.setText(modal.getMovieName());
        rowViewHolder.txtYear.setText(modal.getYear()+"");
        rowViewHolder.txtCost.setText(modal.getBudgetInMillions()+"");
    }
}

@Override
public int getItemCount() {
    return movieList.size()+1; // one more to add header row
}

Motivation

While searching for TableView plugins, I found out that many of the Tableviews are really hard to setup and customize. So had to make one using Recyclerview, for adjusting the row height based on the content text.
