Android set margin of textview programmatically

When I try to set a margin with this code:

 @Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
RelativeLayout.LayoutParams params;
TextView login = (TextView) findViewById(R.id.textView2);
int text_height = login.getHeight();
int text_whidth= login.getWidth();
params = new RelativeLayout.LayoutParams((int)login.getLayoutParams().WRAP_CONTENT, (int)login.getLayoutParams().WRAP_CONTENT);
        params.setMargins(0, 500, 0, 0);

login.setLayoutParams(params);

}

The app crashes on start. How can I set margin without it crashing my app?

Thanks for your help.

here is Method for you, just need to pass parameters 

public static void setMargin(View view, int left, int right, int top, int bottom) {
    ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) 
    view.getLayoutParams();
    params.setMargins(left, top, right, bottom);
    view.setLayoutParams(params);
}

where First Parameter view is Your TextView.

LayoutParams having setMargins method and then set params to setLayoutParams() method of TextView.

LinearLayout.LayoutParams params = new 
LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(10,10,10,10); // setMargins(left, top, right, bottom)
textView.setLayoutParams(params);

Try to replace the following line:

params = new RelativeLayout.LayoutParams((int)login.getLayoutParams().WRAP_CONTENT, (int)login.getLayoutParams().WRAP_CONTENT);

with this one:

params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
