Call to setLayoutParams(...) crashes my app - why?

[Gregary Boyles]

The call to setLayoutParams(...) is causing my app to crash.
If I comment out the line of code in bold then my app run as normal.
What am I doing wrong?

ViewGroup.MarginLayoutParams marginParams = new ViewGroup.MarginLayoutParams(m_textviewStatusCurrent.getLayoutParams());
marginParams.leftMargin -= m_nOffset;
m_textviewStatusCurrent.setLayoutParams(marginParams);

This doesn't work either.

RelativeLayout.LayoutParams layoutparams = (RelativeLayout.LayoutParams)m_textviewStatusCurrent.getLayoutParams();
layoutparams.leftMargin -= m_nOffset;
m_textviewStatusCurrent.setLayoutParams(layoutparams);

In order for someone to help with this you need to show the stack trace from the Logcat output.
And you need to show a bit more code than the above.
Plus there's no code line shown in bold.

To establish why your app crashed, we need to know what exception it generated. This will be shown in the stack trace, displayed in the Logcat view.
