                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Log.d("readtype",""+readtype);
                    if(readtype==0)
                    {
                        readLayout.setVisibility(View.GONE);
                        btnReadMore.setText("READ MORE");
                        btnReadMore.setBackgroundResource(drawable.readmore);
                        readtype=1;

                    }
                    else
                    {
                        readLayout.setVisibility(View.VISIBLE);
                        btnReadMore.setText("READ LESS");
                        btnReadMore.setBackgroundResource(drawable.readless);                   
                        readtype=0;
                    }
                }
            });
            btnBack.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    finish();
                }
            });
            return PagerView;
        }

        @Override
        public void destroyItem(final View arg0, final int arg1,
                final Object arg2) {
            ((ViewPager) arg0).removeView((View) arg2);

        }

        @Override
        public boolean isViewFromObject(final View arg0, final Object arg1) {
            return arg0 == ((View) arg1);

        }

        @Override
        public void finishUpdate(View arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void restoreState(Parcelable arg0, ClassLoader arg1) {
            // TODO Auto-generated method stub

        }

        @Override
        public Parcelable saveState() {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public void startUpdate(View arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return SubMenuIdList.size();
        }

    }

Can anyone please help me up.

i think your code is right. have you tried to set the visibility with int?

setVisibility(0) -> visible  or setVisibility(View.VISIBLE)
setVisibility(4) -> invisible or setVisibility(View.INVISIBLE)
setVisibility(8) -> gone or setVisibility(View.GONE)
