    new LinearLayout.LayoutParams(WRAP_CONTENT, WRAP_CONTENT);

and I

Answer 1

You can use like this one:

LinearLayout myll = (LinearLayout) findViewById(R.id.yourLinearLayout);
myll.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT));
myll.setOrientation(LinearLayout.VERTICAL);

Answer 2

A working sample below (it's LayoutParams.WRAP_CONTENT, NOT LinearLayout.WRAP_CONTENT)

myLayout.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
myLayout.setLayoutParams(layoutParams);

Answer 3

You need to instance LinearLayout. After that you can call setOrientation()

LinearLayout myLayout = ...;
myLayout.setLayoutParams(new LayoutParams(LinearLayout.WRAP_CONTENT, LinearLayout.WRAP_CONTENT);
myLayout.setOrientation(LinearLayout.VERTICAL);

That should do the job :)

For more infos check the Android API.

Answer 4

Simply use as follow :-

LinearLayout mlayout = new LinearLayout(context);
mlayout.setOrientation(2);

2 means Vertical, 1 is used for horizontal.

Answer 5

You can't change LinearLayout's orientation using its LayoutParams. It can be done only with a LinearLayout object.

LinearLayout layout = /* ... */;
layout.setOrientation(LinearLayout.VERTICAL);

Answer 6

In case anyone else arrives here like me looking for the answer for Xamarin, the equivalent is:

LinearLayout layout = /* ... */;
layout.Orientation = Orientation.Vertical;
layout.LayoutParameters = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MatchParent, LinearLayout.LayoutParams.WrapContent);
