New Lib tableviewutil; reduce number of required app specific Classes; added generic parameter POJO; Updated Demo-App

[k3b]

The current implementation at https://github.com/evrencoskun/TableView
requires a lot of copy&paste from example code to use the TableView in a clientapp.

Product vision: reduce the amount of (copied) code to integrate TableView into a clientapp.

• all app specific data comes from tableview independent POJOs (i.e. List<MySamplePojo> from TestData.createSampleData())
• all info how the POJO is displayed in the tableview comes from ColumnDefinition (i.e. List<ColumnDefinition<MySamplePojo>> from TestData.createColumnDefinitions())
• no more need to implement app-specific XxxViewHolder, XxxModell for Cell, Column, RowHeader
• no more need to implement app-specific TableViewAdapter, TableViewModel
• no more need to define app specific layout for table_view_Xxx_layout.xml for Cell, Column, RowHeader
• Instead of the app-specific classes/layouts (mentioned in "no more need") there are generic, app-independant in the new modul tableviewutil.
• For legacy apps the tableview lib can be used as before.

Additional Requirements

• java-8 lamda expressions to define column values and custom cell-view(-holders). See createColumnDefinitions() in TestData.java

Some differences between old and new style app that uses tableview

old style:

build.gradle dependencies:

implementation "com.evrencoskun.library:tableview:$tableview_version"

Mainfragment.java

private void initializeTableView(TableView tableView){
    // Create TableView Adapter
    mTableAdapter = new MyTableAdapter(getContext());
    tableView.setAdapter(mTableAdapter);

    // Create listener
    tableView.setTableViewListener(new MyTableViewListener(tableView));
}

Define app specific classes and resources

• MainFragment.java

• MainActivity.java

• MainViewModel.java

• MyTableViewModel.java

• ColumnHeaderViewHolder.java

• MyTableAdapter.java

• CellModel.java

• RowHeaderViewHolder.java

• MyTableViewListener.java

• ColumnHeaderModel.java

• GenderCellViewHolder.java

• MoneyCellViewHolder.java

• RowHeaderModel.java

• CellViewHolder.java

• ic_down.xml

• ic_up.xml

• activity_main.xml

• fragment_main.xml

• tableview_cell_layout.xml

• tableview_column_header_layout.xml

• tableview_corner_layout.xml

• tableview_gender_cell_layout.xml

• tableview_money_cell_layout.xml

• tableview_row_header_layout.xml

new style:

build.gradle dependencies:

implementation "com.evrencoskun.library:tableview:$tableview_version"
implementation "com.evrencoskun.library:tableviewutil:$tableview_version"

Mainfragment.java

private void initializeTableView(TableView tableView){
    List<ColumnDefinition<MySamplePojo>> columnDefinitions = TestData.createColumnDefinitions();
    List<MySamplePojo> pojos = TestData.createSampleData();
    // Create TableView View model class  to group view models of TableView
    TableViewModel<MySamplePojo> tableViewModel = new TableViewModel(columnDefinitions, pojos);

    // Create TableView Adapter
    TableViewAdapter<MySamplePojo> tableViewAdapter = new TableViewAdapter<>(columnDefinitions);

    tableView.setAdapter(tableViewAdapter);
    tableView.setTableViewListener(new MyTableViewListener(tableView));

    // Create an instance of a Filter and pass the TableView.
    //mTableFilter = new Filter(tableView);

    // Load the dummy data to the TableView
    tableViewAdapter.setAllItems(tableViewModel.getColumnHeaderList(), tableViewModel
            .getRowHeaderList(), tableViewModel.getCellList());

}
