show data in table view in android

Question

I want to get data from database in my android table view.

Should I use loop? Is static good for this?

We could imagine a custom component for android : the TableView.

Its code would be something like :

public class TableView extends TableLayout {

    public TableView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TableView(Context context) {
        super(context);
    }

    public void setAdapter(TableAdapter adapter) {
        removeAllViews();

        for (int row = 0; row < adapter.getRowCount(); row++) {
            TableRow tableRow = new TableRow(getContext());
            TableLayout.LayoutParams params = new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
            tableRow.setLayoutParams(params);
            addView(tableRow);
            for (int column = 0; column < adapter.getColumnCount(); column++) {
                View cell = adapter.getView(row, column);
                tableRow.addView(cell);
                TableRow.LayoutParams cellParams = (android.widget.TableRow.LayoutParams) cell.getLayoutParams();
                cellParams.weight = adapter.getColumnWeight(column);
                                    cellParams.width = 0;
            }
        }
    }
}

And it would use an adapter like this :

public interface TableAdapter {
    int getRowCount();

    int getColumnWeight(int column);

    int getColumnCount();

    T getItem(int row, int column);

    View getView(int row, int column);
}
