二 错误代码还原规则

if…else 语句:

反编译代码

if (paramBoolean)
        paramTextView.setTextColor(-16727809);
       while (true)
       {
         return;
         paramTextView.setTextColor(-1315861);
       }

 还原后

      if (paramBoolean)
         {
           paramTextView.setTextColor(-16727809);
         }
         else
         {
            paramTextView.setTextColor(-1315861);
         }  

会把if ..esle 反编译成 if …while(true)结构.

反编译代码

 if (paramInt1 != 1)
        break label185;
      if (this.countChild_1 == null)
      {
        this.countChild_1 = new PokerCountChild(this.mContext);
        this.countChild_1 = new PokerCountChild(this.mContext);
        this.countChild_1.setPosition((int)(0.83D * BaseGameActivity.screenWidth

 - this.countChild_1.getWidth()), (int)(0.2D * BaseGameActivity.screenHeight));
        this.countChild_1.setCount(paramInt2);
        addOneChild(this.countChild_1);
        if (paramInt2 == 0)
          this.countChild_1.setAlpha(0);
      }
      this.countChild_1.setCount(paramInt2);
    }
    label185: 
    do
      return;
    while (paramInt1 != 2);
    if (this.countChild_2 == null)
    {
      this.countChild_2 = new PokerCountChild(this.mContext);
      this.countChild_2 = new PokerCountChild(this.mContext);
      this.countChild_2.setPosition((int)(0.17D * BaseGameActivity.screenWidth),

 (int)(0.2D * BaseGameActivity.screenHeight));
      this.countChild_2.setCount(paramInt2);
      addOneChild(this.countChild_2);
      if (paramInt2 == 0)
        this.countChild_2.setAlpha(0);
    }
    this.countChild_2.setCount(paramInt2);

还原

 if(i == 1)
            {
                if(countChild_1 == null)
                {
                    countChild_1 = new PokerCountChild(mContext);
                    countChild_1 = new PokerCountChild(mContext);
                    countChild_1.setPosition((int)(0.83D * 

(double)BaseGameActivity.screenWidth - (double)countChild_1.getWidth()), 

(int)(0.2D * (double)BaseGameActivity.screenHeight));
                    countChild_1.setCount(j);
                    addOneChild(countChild_1);
                    if(j == 0)
                        countChild_1.setAlpha(0);
                }
                countChild_1.setCount(j);
            } else
            if(i == 2)
            {
                if(countChild_2 == null)
                {
                    countChild_2 = new PokerCountChild(mContext);
                    countChild_2 = new PokerCountChild(mContext);
                    countChild_2.setPosition((int)(0.17D * 

(double)BaseGameActivity.screenWidth), (int)(0.2D *

 (double)BaseGameActivity.screenHeight));
                    countChild_2.setCount(j);
                    addOneChild(countChild_2);
                    if(j == 0)
                        countChild_2.setAlpha(0);
                }
                countChild_2.setCount(j);
                return;
            }
会将语句倒序,出现break label结构

反编译代码
 
jd-gui有时会将whilei语句翻译成if,此处要将if改成while

switch语句

反编译代码

   switch (this.mBand)
    {
     default:
     case 0:
     case 1:
     case 2:
    }
    while (true)
    {
      return;
      this.mBand.setText("FM1");
      continue;
      this.mBand.setText("FM2");
      continue;
      this.mBand.setText("AM");
    }
还原

switch (mBand)
    {
     case 0:
      mBand.setText("FM1");
      break;
     case 1:
       mBand.setText("FM2");
       break;
     case 2:
       mBand.setText("AM");
       break;
     default:
    }

switch规则就是一个continue对应一个case.要注意是是要外层的continue才算数,在if里的continue不算
