老师视频教程结束了,但是游戏并未完成。下面便开始自己动手完善部分功能
需要完善的功能:
1、设置给定的数独数据数字不可改变
2、设置给定的数独数据数字和玩家填入的数字颜色不同,方便区分
3、判断填写后的数独是否符合数独游戏规则
解决方法:
1、设置给定的数独数据数字不可改变
我的思路,因为给定的数据数字是给定的,而数据是放在一个字符串里的,如下:0代表需要玩家输入的,非0则是给定的
1 private final String str = "061030020050008107000007034009006078003279500570300902190760000802400060640010250";
这样只需要在开一个整型数组来标记,0表示玩家需要填写的,1代表是系统给定的数独数据数字
在Game.java类中
实现根据数独数据字符串获得一个整型数组(isdata[]),
并给一个获取数组方法,
1 public int getIsData(int x,int y){ 2 return isdata[y*9+x]; 3 }
1 //根据字符串数据生成整型数组 2 public int[] fromPuzzleString(String str2) { 3 // TODO Auto-generated method stub 4 // shudu[] = new int[str2.length()]; 5 for(int i=0;i<shudu.length;i++) 6 { 7 shudu[i]=str2.charAt(i)-‘0‘; //吧字符转换为数字] 8 if(shudu[i]!=0) 9 { 10 isdata[i]=1; 11 } 12 } 13 14 return shudu; 15 }
若字符串某字符为‘0‘则整型数组对应数字0,若字符串某数字不为‘0‘则整型数组对应数字1,
然后在调用对话框的时候判断试下是不是玩家输入的单元格即可
1 if(game.getIsData(selectx,selecty)!=1) //如果不是系统初始给定的,则调用对话框,提供数字选择 2 { 3 SelectDialog seldia = new SelectDialog(getContext(),used,this); 4 seldia.show(); 5 }
2、设置给定的数独数据数字和玩家填入的数字颜色不同,方便区分
我的思路,因为给定的数据数字是给定的
1 private final String str = "061030020050008107000007034009006078003279500570300902190760000802400060640010250";
在Game.java类中
还是通过数组isdata[]
1 //根据字符串数据生成整型数组 2 public int[] fromPuzzleString(String str2) { 3 // TODO Auto-generated method stub 4 5 for(int i=0;i<shudu.length;i++) 6 { 7 shudu[i]=str2.charAt(i)-‘0‘; //吧字符转换为数字] 8 if(shudu[i]!=0) 9 { 10 isdata[i]=1; 11 } 12 } 13 14 return shudu; 15 }
在ShuduView类中
得到isdata[]整型数组,若为0,则表示该单元格是玩家填写的数字,用白色画笔构写数字
若为1,则表示该单元格是给定的数独数据的数字,用黑色画笔构写数字
具体代码:
1 //绘制数字-原始数据 2 Paint numberpaint_data = new Paint(); 3 numberpaint_data.setColor(Color.BLACK); //黑色字体 4 numberpaint_data.setStyle(Style.STROKE); 5 numberpaint_data.setTextSize((float) (height*0.75)); 6 numberpaint_data.setTextAlign(Align.CENTER);//居中对齐 7 //绘制数字-玩家填写数据 8 Paint numberpaint_new = new Paint(); 9 numberpaint_new.setColor(Color.WHITE); //白色字体 10 numberpaint_new.setStyle(Style.STROKE); 11 numberpaint_new.setTextSize((float) (height*0.75)); 12 numberpaint_new.setTextAlign(Align.CENTER);//居中对齐 13 14 FontMetrics fm = numberpaint_data.getFontMetrics(); 15 float x = width/2; 16 float y = height/2-(fm.ascent-fm.descent)/2;//获取画笔写数字的位置 17 // 计算文字高度 18 float fontHeight = fm.bottom - fm.top; 19 // 计算文字baseline 20 float textBaseY = height - (height - fontHeight) / 2 - fm.bottom; 21 //canvas.drawText("1", 3*width+x, textBaseY, numberpaint); 22 //绘制数字 23 for(int i=0;i<9;i++) 24 { 25 for(int j=0; j<9;j++) 26 { 27 if(game.getIsData(i, j)==1) 28 canvas.drawText(game.getTitlStringe(i,j), i*width+x, j*height+textBaseY, numberpaint_data); 29 else 30 canvas.drawText(game.getTitlStringe(i,j), i*width+x, j*height+textBaseY, numberpaint_new); 31 } 32 }
3、判断填写后的数独是否符合数独游戏规则
在给定初始数据时
1 private final String str = "061030020050008107000007034009006078003279500570300902190760000802400060640010250"; //初始化数据 2 private final String str_da = "761934825354628197928157634219546378483279516576381942195762483832495761647813259"; //答案数据
判断是否完成数独方法
1 private void judge() { 2 // TODO Auto-generated method stub 3 StringBuffer a = new StringBuffer((String) game.getStr_da()); 4 int[] b = game.getShuduku(); 5 StringBuffer c = new StringBuffer(); 6 for(int i=0;i<b.length;i++) 7 { 8 c.append(b[i]); 9 } 10 // String c= String.valueOf(b); 11 if(a.toString().equals(c.toString())) 12 { 13 AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); 14 builder.setTitle("~~通知~~"); 15 builder.setIcon(R.drawable.app_xin); 16 builder.setMessage("恭喜通关!!!"); 17 builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 18 @Override 19 public void onClick(DialogInterface arg0, int arg1) { 20 // TODO Auto-generated method stub 21 } 22 }); 23 AlertDialog dialog = builder.create(); 24 dialog.show(); //显示、 25 } 26 } 27 }
