java - CSS 仅应用于奇数行

Question

我有一个填充了 Samples 对象的 TableView 。如果 Samples 对象的属性 = true，我想填充 TableRow。我使用了基于 jewelsea 的这个答案的方法:Disable TableRow based on data

int i = 0;
if (tblSamples.getItems().size() > 0) {
    for (Node n : tblSamples.lookupAll("TableRow")) {
        if (n instanceof TableRow) {
            TableRow row = (TableRow) n;
            row.getStyleClass().removeAll("hasMastitisRow");

            if (tblSamples.getItems().get(i).getClinicalMastitis()) {
                row.getStyleClass().add("hasMastitisRow");
            }
            i++;

            if (i == tblSamples.getItems().size()) {
                break;
            }
        }
    }
}

CSS:

.hasMastitisRow {  
    -fx-control-inner-background: linear-gradient(#FFFFFF 85%, red 100%);
}

但是，它只适用于奇数行，偶数行似乎不起作用？

编辑:当 CSS 应用于偶数行时(在奇数行我没有错误)，我似乎也遇到了以下错误:

编辑: 新方法但结果相同(应用于奇数行，而不是偶数行):

tc_Samples_Quarter.setCellFactory(new Callback<TableColumn<Samples, String>, TableCell<Samples, String>>() {
        @Override
        public TableCell<Samples, String> call(TableColumn<Samples, String> soCalledSampleRowStringTableColumn) {
            return new TableCell<Samples, String>() {
                @Override
                public void updateItem(final String item, final boolean empty) {
                    super.updateItem(item, empty);
                    this.getTableRow().getStyleClass().remove("hasMastitisRow");
                    if (item != null) {
                        setText(item);
                        this.getTableRow().getStyleClass().add("hasMastitisRow");
                    } else {
                        setText(null);
                    }
                }
            };
        }
    });

对您的一些代码感到好奇。首先，您要像这样获取节点:

for (Node n : tblSamples.lookupAll("TableRow")) {

然后你做一个检查实例看看它是否是一个 TableRow

if (n instanceof TableRow) {

有必要吗？ lookupAll 是否有可能返回不是 TableRow 的节点？如果是这样，那么一种可能性是 i 索引的增量仅发生在 if (n instanceof TableRow) 内部，所以 i仅当它是 TableRow 时才递增。 i 是否与索引中的元素不匹配，因为它跟不上循环？
