How to create a dynamic table of data in android?

Question

I've looked around at tutorials for TableLayouts and other such things, but all of it seems to be programmed as a static number of rows with textview's. I'm wondering if it would be possible to create a simple table of data, with 3 columns and a variable set of rows I can add/remove items from in the Java code.

Basically, have something like this:

DATA DATA DATA
row1 data data
row2 data data

and fill this table with data from an object array in the activity's Java class. Later, if I want to add another object, it will just create another row.

For instance, if I have this in java:

Class data{
    public data(String d1, String d2, String d3){
     data1=d1;
     data2=d2;
     data3=d3;
}
}

and this in the activity class:

Class activity{
data info[] = {
new data("row1", "row1", "row1"), new data("row2","row2","row2"),
new data("row3","row3","row3")};
}
}

And I will use a for loop to add this data into the table in the activity, regardless of how many rows I need for all of it to be fit. If I add a new object of row4, it will just add another row, and end with:

row1 row1 row1
row2 row2 row2
row3 row3 row3

I hope I haven't been too vague... Thanks in advance, fellas! :)

If you want to have a completely dynamic table as you are used to by ListView or RecyclerView there is the table view on GitHub.

Your code will look like this:

String[][] myData = new String[][] { {"row1", "row1", "row1"},
                                     {"row2", "row2", "row2"},
                                     {"row3", "row3", "row3"} };

TableDataAdapter<String[]> myDataAdapter = 
        new SimpleTableDataAdapter(getContext(), myData);
TableHeaderAdapter myHeaderAdapter = 
        new SimpleTableHeaderAdapter(getContext(), "Header1", "Header2", "Header3");

TableView<String[]> table = findViewById(R.id.table);
table.setDataAdapter(myDataAdapter);
table.setHeaderAdapter(myHeaderAdapter);

Because the data is managed in a model you can update the table very easily.

myDataAdapter.getData().add(new String[]{"row4", "row4", "row4"});
myDataAdapter.getData().add(new String[]{"row5", "row5", "row5"});
myDataAdapter.notifyDatasetChanged();

As the table provides a lot of customization and styling possibilities result could look like this: (or completely different)
