public class Display extends Activity {

    //get the the BUNDLE inside the intent
    Bundle m = this.getIntent().getExtras();

    String [] TeamName = m.getStringArray("TeamName");
    String[] SWin = m.getStringArray("Win");
    String[] SDraw =  m.getStringArray("Draw");
    int [] Win = new int[10];
    int [] Draw = new int [10];

Answer 1

Java 数组索引从零开始。

这行代码：

int [] Win = new int[10];

删除包含 10 个项目的数组。这些项目的索引范围为 0..9。

这行代码：

Win[10] = Integer.parseInt(SWin[10]);

尝试为数组分配一个超出范围的值。我还怀疑在此之前访问 SWin[10] 会崩溃。

我想你想说的是：

for (int index = 0; index < (SWin.length) && (index < 10); index++)
{
   Win[index] = Integer.ParseInt(SWin[index]);   
}
