public class DataGridView extends LinearLayout

DataGridView can be used to display a list or table of data records providing features like pagination.

Its takes a List of Maps that contains data and renders each row using a set of ColumnInterface presenting data in the form of a table.

The minimal code needed to use DataGridView is as follows:

dataGridView = (DataGridView) findViewById(R.id.data_view);
dataGridView.setPageSize(3);
List data = "...;
dataGridView.setData(data);

Its also possible to override which columns are used in the grid and customize those columns as one wishes.

Assuming in the data provided to the gridview looks like this

[{“first_name”:”jake”, “age”:”4”}, {“first_name”:”joan”, “age”:”6”}, ]

The ealier example will render both the firstname and age column on the grid we can tell the gridview to only render the firstname by DataGridView.setColumns(Map) as shown below:

Map cols = new HashMap();
cols.put("first_name", new Column(this,"first_name","First Name"));
dataGridView.setColumns(cols);
