java.lang.NoSuchMethodError: android.widget.LinearLayout$LayoutParams

Question

TextView tv = new TextView(getActivity());
                LayoutParams tvLp = new LayoutParams((new LayoutParams(
                        0, LayoutParams.WRAP_CONTENT,1f)));
                tvLp.gravity = (Gravity.BOTTOM);
                tv.setLayoutParams(tvLp);

When I run the above code in pre-Kitakat devices I am getting No such method error. I found this solution Android: java.lang.NoSuchMethodError on LinearLayout$LayoutParams.<init> in which the below code is used to avoid such error. But using the below solution, I cannot programmatically set gravity,layout weights etc. Is there any workaround to solve this?

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams((ViewGroup.MarginLayoutParams)(new    LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)));

What do you mean by "cannot programmatically set gravity,layout weights etc", does it crash? Please be more specific — Marcus

LayoutParams tvLp = new LayoutParams((new LayoutParams(
                        0, LayoutParams.WRAP_CONTENT,1f)));

the copy constructor, the one that takes a LayoutParams as object, was introduced with api level 19. But you can use this, that is part of the sdk since api 1.

 LayoutParams tvLp = new LayoutParams(
                            0, LayoutParams.WRAP_CONTENT,1f);
