我有一个Java表,TableModel.each row(element)
有一个ID。我想显示具体的ID。如何过滤这些元素?选定的ID可以更改。
例如:
public class L {
int id;
String name;
String family;
}
//----
private static final String[] columnNames = { "name","family"};
private static final Class[] columnClasses = {class.String.class,String.Class};
private Vector<L> list = Vector<L>();
list.add(new L(1,"A","b"));
.
.
.
list.add(new L(100,"AB","aa");
我想显示带有此ID的元素,例如{1 39 45 55 22}。
如何过滤这些ID?
答案 0 :(得分:3)
你可以使用RowFilter和TableRowSorter:
final int[] ids = new int[]{1, 39, 45, 55, 22};
RowFilter<Object, Object> filter = new RowFilter<Object, Object>() {
public boolean include(Entry entry) {
L currentObject = (L) (entry.getValue(0));
for(int i=0;i<ids.length;i++){
if(currentObject.getId()==ids[i]){
return true;
}
}
return false;
}
};
TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(model);
sorter.setRowFilter(filter);
yourTable.setRowSorter(sorter);
经过测试,它适用于我
希望这有帮助
