我希望获取数组中的所有值,并以不通过单个调用存储的方式将它们存储到listview中。 以下是我的代码,有人帮我修理吗? 是否有一个变量可以表示数组的所有内容
这是我的代码:
String[] TKA = new String[100];
JTable table;
Object tableData[][]={
{TKA[1],TKA[2],TKA[3],TKA[4],TKA[5]},
{TKA[6],TKA[7],TKA[8],TKA[9],TKA[10]},
{TKA[11],TKA[12],TKA[13],TKA[14],TKA[15]},
{TKA[16],TKA[17],TKA[18],TKA[19],TKA[20]},
{TKA[21],TKA[22],TKA[23],TKA[24],TKA[25]},
{TKA[26],TKA[27],TKA[28],TKA[29],TKA[30]},
{TKA[31],TKA[32],TKA[33],TKA[34],TKA[35]},
{TKA[36],TKA[37],TKA[38],TKA[39],TKA[40]},
{TKA[41],TKA[42],TKA[43],TKA[44],TKA[45]},
{TKA[46],TKA[47],TKA[48],TKA[49],TKA[50]},
{TKA[51],TKA[52],TKA[53],TKA[54],TKA[55]},
{TKA[56],TKA[57],TKA[58],TKA[59],TKA[60]},
{TKA[61],TKA[62],TKA[63],TKA[64],TKA[65]},
{TKA[66],TKA[67],TKA[68],TKA[69],TKA[70]},
{TKA[71],TKA[72],TKA[73],TKA[74],TKA[75]},
{TKA[76],TKA[77],TKA[78],TKA[79],TKA[80]},
{TKA[81],TKA[82],TKA[83],TKA[84],TKA[85]},
{TKA[86],TKA[87],TKA[88],TKA[89],TKA[90]},
{TKA[91],TKA[92],TKA[93],TKA[94],TKA[95]},
{TKA[96],TKA[97],TKA[98],TKA[99],TKA[100]},
};
String[] columnTitle = { "AA","BB","CC","DD","EE" };
table = new JTable(tableData , columnTitle);
JScrollPane jt = new JScrollPane(table);
add(jt);
jt.setBounds(10, 200, 700, 500);

创建一个新的TableModel
,用于定义您希望表格的显示方式。
<强>应用强>
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class StackExample {
public static void main(String[] args) {
MyTableModel model = new MyTableModel("This is some string that I want to show");
// Create a JTable and tell it to display our model
JTable table = new JTable(model);
// Display it all in a scrolling window and make the window appear
JFrame frame = new JFrame("FileTableDemo");
frame.getContentPane().add(new JScrollPane(table), "Center");
frame.setSize(600, 400);
frame.setVisible(true);
}
}
<强>的TableModel 强>
import javax.swing.table.AbstractTableModel;
public class MyTableModel extends AbstractTableModel {
private static final long serialVersionUID = 1L;
private String data;
String[] columnTitle = { "AA","BB","CC","DD","EE" };
public MyTableModel(String data) {
this.data = data;
}
@Override
public int getRowCount() {
return data.length() / 5;
}
@Override
public int getColumnCount() {
return 5;
}
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
return data.charAt((rowIndex * 5) + columnIndex);
}
@Override
public String getColumnName(int column) {
return columnTitle[column];
}
}

改为使用集合,然后转换为String[][]
:
ArrayList<String[]> temp = new ArrayList<String[]>();
int i = 0;
String innerArray;
while( i < TKA.length){
innerArray = new String[5];
for(int j = 0 ; j < innerArray.length ; j++){
innerArray[j] = TKA[i];
i++;
}
temp.add(innerArray);
}
String[][] result = temp.toArray(new String[0][0]);
