android自己写的时间轮片算法错那里了？

Java code

package com.sime;import java.util.Random;import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.text.Layout;import android.view.ViewGroup.LayoutParams;import android.widget.LinearLayout;import android.widget.ProgressBar;import android.widget.TextView;import android.widget.Toast;public class RunscActivity extends Activity {    private int jcbt;    private int cput;    private int timeout=0;    private int s=0;     LinearLayout layout;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.runnables);       layout = (LinearLayout) findViewById(R.id.layoutBackground);         jcbt= this.getIntent().getExtras().getInt("jcbtnumber");         cput=this.getIntent().getExtras().getInt("cputimes");           final ProgressBar a[]=new ProgressBar[10];           final int b[]={10,20,30,40};           final Runnable  uirun[]=new Runnable[10];          for(int i=0;i<jcbt;i++)          {                                       ProgressBar bar =  new ProgressBar(this,null,android.R.attr.progressBarStyleHorizontal);             layout.addView(bar, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));              Runnable callback= new Runnable()              {                @Override                public void run() {                    // TODO Auto-generated method stub                    a[s++].incrementProgressBy(b[s++]);                }                                };             a[i]=bar;              uirun[i]=callback;                       }                                       final Handler handler=new Handler();             final Thread thread=new Thread()             {                              @Override                 public void run()                 {                                      try {                                              for(int m=0;m<10;m++)                     {                         Toast.makeText(getApplicationContext(), "第"+(m+1)+"次轮转",                                   Toast.LENGTH_SHORT).show();                         for(int i=0;i<jcbt;i++)                         {                                                                               Thread.sleep(1000);                             handler.post(uirun[i]);                             Toast.makeText(getApplicationContext(), "执行进程"+i,                                    Toast.LENGTH_SHORT).show();                                                      }                                                                       }                     }                     catch (InterruptedException e){                        // TODO Auto-generated catch block                        e.printStackTrace();                    }                                                                            }                              };              thread.start();                                                   }                 }

错误就是

错在何处呢？jcbt和cput都是我从另一个界面传过来的整数

[解决办法]
Android中不能在子线程中来刷新UI线程：
你把 Toast.makeText的调用放在UI线程就可以了
