android - how to use the values obtained from onmeasure in a separate thread -

i using omeasure method find width of vew , returning correct values.

protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {           parentwidth = measurespec.getsize(widthmeasurespec);         parentheight = measurespec.getsize(heightmeasurespec);         this.setmeasureddimension(                 parentwidth, parentheight);         //log.d("measure", "width = " + parentwidth + ", height = "                  //+ this.getmeasuredheight());     } 

now want use value parentwidth in following if statement

public void run() {     a.flag2=true;     while(a.flag2)     {            try         {             sleep(200);         }         catch(exception e)         {         }      if(!a.flag1)     {         a.leftx+=10;         a.rightx+=10;         if(!a.flag3)         {             a.strt-=15;             a.arc+=15;         }            else         {             a.strt+=15;             a.arc-=15;         }      }      if(a.flag1)     {         a.leftx-=10;         a.rightx-=10;         if(!a.flag3)             a.arc+=15;         if(a.flag3)             a.arc-=15;     }         if(a.rightx==432)     {          a.topy+=60;         a.bottomy+=60;         a.flag1=true;         a.strt=180;         a.arc=315;       }      if(a.leftx==0)     {         a.topy+=60;         a.bottomy+=60;         a.flag1=false;         a.strt=45;         a.arc=315;      }     if(a.bottomy>=660)     {         a.topy=60;         a.bottomy=120;     }      if(a.strt==0 || a.arc==360)     {         a.flag3=true;     }      if(a.strt==45 || a.arc==315)     {         a.flag3=false;     }     if(a.n3==a.rightx&&a.n5==(a.topy+a.bottomy)/2)     {         a.i+=1;         int low=1;         int high=10;          a.n=a.r.nextint(high-low);         a.n3=(a.n*10)+150;         a.n5=(a.n*60)+90;          a.f1=(float)a.n3;         a.f2=(float)a.n5;        }     a.postinvalidate();     } } } 

this if statement defined inside thread class.but somehow value of parentwidth not being read her.if harcode "a.rightx==432" works.but dont want hardcode it. how should value of parentwidth in thread?
