Question

需要一些帮助，创建一个应用程序，发送十个团队名称的结果，赢得和绘制的游戏进行计算以计算总分然后应该显示它们但点击继续按钮后，应用程序始终崩溃。下面的代码是什么指南什么都出错了非常感谢

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;


public class Display extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_display);

    //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];


    // Convert to from string to integer Win
    Win[1] = Integer.parseInt(SWin[1]);
    Win[2] = Integer.parseInt(SWin[2]);
    Win[3] = Integer.parseInt(SWin[3]);

Java数组索引基于零。

这行代码：

int [] Win = new int[10];

Delcares包含10个项目。这些项目的索引范围为0..9。

这行代码：

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

尝试为数组指定超出范围的值。我还怀疑在此之前访问SWin [10]崩溃了。

我想你想说的是：

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