java Android league应用程序不断崩溃

Question

需要一点帮助，创建一个应用程序，发送十个球队名称、赢得的比赛和平局的结果，并进行计算得出总积分，然后显示它们 但单击“继续”按钮后，应用程序总是崩溃。 这是代码，有什么错误的指南吗 非常感谢

package com.example.leaguetest;

import 安卓.app.Activity;
import 安卓.os.Bundle;
import 安卓.view.Menu;
import 安卓.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]);
    Win[4] = Integer.parseInt(SWin[4]);
    Win[5] = Integer.parseInt(SWin[5]);
    Win[6] = Integer.parseInt(SWin[6]);
    Win[7] = Integer.parseInt(SWin[7]);
    Win[9] = Integer.parseInt(SWin[8]);
    Win[9] = Integer.parseInt(SWin[9]);
    Win[10] = Integer.parseInt(SWin[10]);
    // Convert to from string to integer Draw
    Draw[1] = Integer.parseInt(SDraw[1]);
    Draw[2] = Integer.parseInt(SDraw[2]);
    Draw[3] = Integer.parseInt(SDraw[3]);
    Draw[4] = Integer.parseInt(SDraw[4]);
    Draw[5] = Integer.parseInt(SDraw[5]);

    Draw[7] = Integer.parseInt(SDraw[7]);
    Draw[8] = Integer.parseInt(SDraw[8]);
    Draw[9] = Integer.parseInt(SDraw[9]);
    Draw[10] = Integer.parseInt(SDraw[10]);


    //Calculation

    int Result1 = (Win[1]* 3)+Draw[1];



    TextView Result1T=(TextView)findViewById(R.id.TextView1);
    Result1T.setText(TeamName[1] );         

    TextView Result2T=(TextView)findViewById(R.id.TextView2);
    Result2T.setText( Result1);

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.display, menu);
    return true;

Java数组索引是基于零的

这行代码：

int [] Win = new int[10];

Delcares包含10个项目的数组。这些项目的索引范围为0。。九,

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]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]);   
}
