Codename one是TableModel中的一个循环

Question

我正试图在TableModel中放置一个循环，以循环arraylist中的所有项目，从而插入表中的所有行，这样我就可以将其添加到表单中，并向用户显示所有项目公共类ListArticlesForm扩展Form｛

public ListArticlesForm(Form previous) {
setTitle("List all articles");
SpanLabel sp = new SpanLabel();
sp.setText(ServiceTask.getInstance().getAllArticles().toString());
ArrayList<Articles> articles = ServiceTask.getInstance().getAllArticles();
TableModel model = new DefaultTableModel(new String[]{"name", "description", "label", "quantity", "rating", "rate"}, 
new Object[][]{
{
// I WANT TO PLACE A FOR HERE (this is showing only the first row ! 
articles.get(0).getName(), articles.get(0).getDescription(), articles.get(0).getLabel(), articles.get(0).getQuantity(), articles.get(0).getRating(), add(createStarRankSlider())
},});
Table table = new Table(model);
add(table);
getToolbar().addMaterialCommandToLeftBar("", FontImage.MATERIAL_ARROW_BACK, e -> previous.showBack());
}

}

Answer 1

不能在数组内创建一个数组作为for循环。你需要早点做一行。

Object[][] rows = new Object[articles.size()][];
for(int iter = 0 ; iter < rows.length ; iter++) {
rows[iter] = new Object[] {
articles.get(iter).getName(), articles.get(0).getDescription(), articles.get(0).getLabel(), articles.get(0).getQuantity(), articles.get(0).getRating(), add(createStarRankSlider())
};
}
TableModel model = new DefaultTableModel(new String[]{"name", "description", "label", "quantity", "rating", "rate"}, rows);

现在，在我运行项目后，除了排名星外，表行都会正确显示在表外和冒号内显示一个文本：创建星级的功能是：

private Slider createStarRankSlider(int id) {
Slider starRank = new Slider();
starRank.setEditable(true);
starRank.setMinValue(0);
starRank.setMaxValue(10);
int fontSize = Display.getInstance().convertToPixels(3);
Font fnt = Font.createTrueTypeFont("Handlee", "Handlee-Regular.ttf").
derive(fontSize, Font.STYLE_PLAIN);
Style s = new Style(0xffff33, 0, fnt, (byte) 0);
Image fullStar = FontImage.createMaterial(FontImage.MATERIAL_STAR, s).toImage();
s.setOpacity(100);
s.setFgColor(0);
Image emptyStar = FontImage.createMaterial(FontImage.MATERIAL_STAR, s).toImage();
initStarRankStyle(starRank.getSliderEmptySelectedStyle(), emptyStar);
initStarRankStyle(starRank.getSliderEmptyUnselectedStyle(), emptyStar);
initStarRankStyle(starRank.getSliderFullSelectedStyle(), fullStar);
initStarRankStyle(starRank.getSliderFullUnselectedStyle(), fullStar);
starRank.setPreferredSize(new Dimension(fullStar.getWidth() * 5, fullStar.getHeight()));
starRank.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent evt) {
ServiceTask.getInstance().UpdateRank(id,starRank.getIncrements());
Dialog.show("Success","thank you for rating our product",new Command("OK"));
}
});
return starRank;
}
