When the layout visibility is set to GONE, you don’t see my spinner, which is outside the layout

In my XML, I have a “Select Operator” counter, and then a line layout containing some Editing Texts, and again a “Spinner” Select Region.

Below the layout, I have an edit text and a button. On the Press button, even to set the layout visibility as GONE or VISIBLE.

When I set the visibility as GONE, I can see the "Select Operator" counter, but when I set the visibility as VISIBLE, I do not see my counter. I do not know why this is happening.

Can someone tell me where the problem is.

My XML:

My Java file:

    l_TNEB = (LinearLayout) getActivity().findViewById(R.id.llayout_electricity_TNEBLAYOUTl);
        b_paybill = (Button) getActivity().findViewById(R.id.blayout_electricity_RECHARGEbt);

        b_paybill.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if(l_TNEB.getVisibility()== View.VISIBLE)
                {
                    l_TNEB.setVisibility(View.GONE);
                }else {
                    l_TNEB.setVisibility(View.VISIBLE);
                }
            }
        });

You can see the Spinner operator

As Mahesh B said,

Linear Layout "Wrap_Content" "Remove Gravity". .
