有人能看看这个code对我和帮助我试图从另一个显示数据类

Could someone have a look at this code for me and help me out with trying to display data from another class

TextView tv = (TextView)findViewById(R.id.bill_periodFrom);
tv.setText(itemisedbill.getperiodFrom());
tv = (TextView)findViewById(R.id.bill_periodTo);
tv.setText(itemisedbill.getperiodTo());
tv = (TextView)findViewById(R.id.bill_cost);
tv.setText(itemisedbill.getcost());
tv = (TextView)findViewById(R.id.bill_amountUsed);
tv.setText(itemisedbill.getamountUsed());

这是我遇到的麻烦的code的一小部分，日食说，itemisedbill在空

That's a small part of the code I'm having trouble with, eclipse says that itemisedbill in null
