通过了几个月坚持不懈的努力，我们组也终于完成了最终成果。关于趣拼图，我们从最初的界面设计到现在的完成，其中也经历了许多，也遇到了很多问题，但我们也都解决了，也从中了解到完成一个项目有多不容易，也从中体会到了团体合作的重要性，下面就先展示一下关于中等的拼图的代码经，这是经过修改最多的一个部分。

     
         
              
               
                  
                       
                        
                    
                   
                       
                        
                    
                
           
          
          
          
             
              
              
              
              
              
              
              
              
              
              
              
              
              
              
              
          
      
     以及JAVA代码：

public class GameZnptZhongDengActivity extends Activity implements View.OnClickListener,Chronometer.OnChronometerTickListener  {
     int bc_gezi = 4;    Button [][] gezi = new Button [bc_gezi][bc_gezi];    Game2GeziYiDong yidong_zd = new Game2GeziYiDong();    TextView text_step , gameOver , overStep;    Chronometer timer;    int step , time = -2;    int sign;    int [][] Init_gz = {
                    {8,1,15,11,14,5,2,12,3,13,10,4,9,7,6},                   {15,13,11,2,8,6,9,7,14,4,12,5,3,10,1},                   {8,12,11,2,9,15,7,14,3,6,1,5,4,13,10},                   {4,9,2,8,6,1,12,10,13,7,14,15,5,3,11},                   {7,13,6,14,12,8,9,10,5,4,11,15,1,3,2},                   {13,6,14,9,3,12,2,11,7,15,8,10,5,1,4},                   {15,5,1,14,6,11,2,4,13,7,12,9,3,10,8},                   {10,9,1,8,13,5,11,7,3,14,4,12,6,2,15},                   };    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);       getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  WindowManager.LayoutParams.FLAG_FULLSCREEN);       requestWindowFeature(Window.FEATURE_NO_TITLE);       setContentView(R.layout.game2zhongdeng);       gezi[0][0]=(Button)findViewById(R.id.game2_ZD_num1);       gezi[0][1]=(Button)findViewById(R.id.game2_ZD_num2);       gezi[0][2]=(Button)findViewById(R.id.game2_ZD_num3);       gezi[0][3]=(Button)findViewById(R.id.game2_ZD_num4);       gezi[1][0]=(Button)findViewById(R.id.game2_ZD_num5);       gezi[1][1]=(Button)findViewById(R.id.game2_ZD_num6);       gezi[1][2]=(Button)findViewById(R.id.game2_ZD_num7);       gezi[1][3]=(Button)findViewById(R.id.game2_ZD_num8);       gezi[2][0]=(Button)findViewById(R.id.game2_ZD_num9);       gezi[2][1]=(Button)findViewById(R.id.game2_ZD_num10);       gezi[2][2]=(Button)findViewById(R.id.game2_ZD_num11);       gezi[2][3]=(Button)findViewById(R.id.game2_ZD_num12);       gezi[3][0]=(Button)findViewById(R.id.game2_ZD_num13);       gezi[3][1]=(Button)findViewById(R.id.game2_ZD_num14);       gezi[3][2]=(Button)findViewById(R.id.game2_ZD_num15);       gezi[3][3]=(Button)findViewById(R.id.game2_ZD_num16);       text_step=(TextView)findViewById(R.id.znpt_zd_step);       gameOver=(TextView)findViewById(R.id.game2_zd_Over);       overStep=(TextView)findViewById(R.id.game2_zd_time_step);        timer     = (Chronometer)findViewById(R.id.myTimer);       yidong_zd.setGezi(gezi);       timer.setOnChronometerTickListener(this);       int num = (int)(Math.random()*Init_gz.length);       for( int i = 0 ; i < bc_gezi ; i ++ ){
           for( int j = 0 ; j < bc_gezi ; j ++  ){
              gezi[i][j].setOnClickListener(this);             if( i == (bc_gezi-1) && j == (bc_gezi-1) ){
                 continue;             }             gezi[i][j].setText(Integer.toString(Init_gz[num][i*bc_gezi+j]));          }       }    }    public void onChronometerTick(Chronometer chronometer){
        time ++;    }    public void onClick(View view){
        for( int i = 0 ; i < bc_gezi ; i ++ ){
           for( int j = 0 ; j < bc_gezi ; j ++  ){
              if(view == gezi[i][j]){
                 if(yidong_zd.move(bc_gezi,i,j)){
                    step ++;                   text_step.setText(Integer.toString(step));                   if(sign == 0){
                       timer.setBase(SystemClock.elapsedRealtime());   //���û�׼ʱ��                      timer.start();                      sign = 1;                   }                   if(yidong_zd.judge(bc_gezi)){
                       //  ��Ϸ����                      gameOver.setText("��Ϸ����");                      overStep.setText("���ò���Ϊ"+Integer.toString(step)+"����ʱ��Ϊ"+Integer.toString(time));                      gezi[bc_gezi-1][bc_gezi-1].setText("-1");                   }                }             }          }       }    } }

这就是最后修改好的中等程度代码，改完了的是没有问题的。
