How do I show only two digits after decimal

Question

I am getting Value for mGTotal like: 179.257856

but now I just want to show only two digits after decimal, like: 179.25

    @Override
    protected void onResume() 
    {
        super.onResume();
        if (Constants.mItem_Detail.size() == 0) 
        {
            return;
        }

        Double mGTotal = Double.parseDouble(Constants.mItem_Detail.get(0).get(SingleProductActivity.KEY_TOTAL));
        for (int i = 1; i < Constants.mItem_Detail.size(); i++) 
        {   
        mGTotal = mGTotal + Double.parseDouble(Constants.mItem_Detail.get(i).get(SingleProductActivity.KEY_TOTAL));
        }
        mGrandTotal = String.valueOf(mGTotal);
        mTxtViewGrandTotal.setText(mGrandTotal);
        myTextVeiwGrandTotal.setText(mGrandTotal);
        mTotal = String.valueOf(Constants.mItem_Detail.size());
        mItems.setText(mTotal);

}
}

use Decimalformat

DecimalFormat df = new DecimalFormat("#.##");
System.out.println(df.format("179.257856"));// which gives result as 179.25

You are very close to your answer, I guess below line will work for you:

 mTxtViewGrandTotal.setText(new DecimalFormat("##.##").format(mGTotal));

and complete method should look like this:

   @Override
    protected void onResume() 
    {
        super.onResume();
        if (Constants.mItem_Detail.size() == 0) 
        {
            return;
        }

        Double mGTotal = Double.parseDouble(Constants.mItem_Detail.get(0).get(SingleProductActivity.KEY_TOTAL));
        for (int i = 1; i < Constants.mItem_Detail.size(); i++) 
        {   
        mGTotal = mGTotal + Double.parseDouble(Constants.mItem_Detail.get(i).get(SingleProductActivity.KEY_TOTAL));
        }
        mGrandTotal = String.valueOf(mGTotal);
        mTxtViewGrandTotal.setText(mGrandTotal);
        myTextVeiwGrandTotal.setText(mGrandTotal);
        mTxtViewGrandTotal.setText(new DecimalFormat("##.##").format(mGTotal));
        mTotal = String.valueOf(Constants.mItem_Detail.size());
        mItems.setText(mTotal);

}
