我必须实现一个JTable，其中必须选择一行（总是）。不允许空选择。我在初始化期间选择了第一行：
table.setRowSelectionInterval(0, 0);
另外，我正在使用
table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
但是用户仍然可以使用CLick + Ctrl取消选择一行。
最简单的方法是确保在表格中始终选择一行（exaclty）？
答案 0 :(得分：20)
如果您创建了JTable实例，只需使用：
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/searchField" android:layout_row="0" android:layout_column="0"
android:drawableLeft="@drawable/search"
android:background="@drawable/rounded_edittext" android:minHeight="50dp"/>
答案 1 :(得分：15)
现在，您可以添加MouseListener s，SelectionListener s，KeyListener和密钥绑定来尝试解决此问题。或者，你可以解决问题的核心。
ListSelectionModel负责管理选择细节。
您可以为行选择提供自己的ListSelectionModel
public class ForcedListSelectionModel extends DefaultListSelectionModel {
public ForcedListSelectionModel () {
setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
}
@Override
public void clearSelection() {
}
@Override
public void removeSelectionInterval(int index0, int index1) {
}
}
只需将它设置在你的桌子上......
table.setSelectionModel(new ForcedListSelectionModel());

最简单的方法是确保一个（exaclty）行总是如此 选中表？
有三种（基本上）选择类型
JTable.setRowSelectionAllowed(boolean);
JTable.setColumnSelectionAllowed(boolean);
JTable.setCellSelectionAllowed(boolean);
修改
也适合我
int row = table.getSelectedRow();
if ((row > -1)) {
table.setRowSelectionInterval(row, row);
}
}
答案 3 :(得分：1)
我会使用JTable#setRowSelectionAllowed，因为它可以确保选择一行。
答案 4 :(得分：0)
此代码将其更改回所需的索引，并为用户提供永不更新的外观。
