Different font size of strings in the same TextView
...ativeSizeSpan.
Just get the dimension in pixels of the desired text size
int textSize1 = getResources().getDimensionPixelSize(R.dimen.text_size_1);
int textSize2 = getResources().getDimensionPixelSize(R.dimen.text_size_2);
and then create a new AbsoluteSpan based on the text
String text1 = "Hi"...
LPCSTR, LPCTSTR and LPTSTR
...i.e. a mutable T-string pointer, not an LPCTSTR. What you are doing is
1) convert string (a CString at a guess) into an LPCTSTR (which in practise means getting the address of its character buffer as a read-only pointer)
2) convert that read-only pointer into a writeable pointer by casting away it...
