setVisibility(View.GONE) not working for textview
I am retrieving and displaying values from a database but all queries don't return the same number of columns so I have to hide the ones that are not required. java:

The xml for that element is:
<LinearLayout
android:id="@+id/linearLayout4"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="@+id/tit_fax"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight=".4"
android:text="FAX"
android:visibility="visible"
android:textSize="14dp" />
<TextView
android:id="@+id/fax"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight=".6"
android:visibility="visible"
android:text=" " />
</LinearLayout>
But it is still visible when it should have been gone

Also can happen (not this case) that the gone is ignored if the view is referenced by a group like this
<androidx.constraintlayout.widget.Group
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:constraint_referenced_ids="myTextView"
tools:visibility="visible" />

On my 4.1.2 device, TextView (it was actually an AutoCompleteTextView) did not want to accept setVisibility(View.GONE) because the box had focus. The problem was this was the last element on the screen, so I spent a while before I found an innocent target to shift the focus to. I had to use setFocusableInTouchMode(true) for that other view, because otherwise its requestFocus() was silently ignored, as well as the TextView's clearFocus().

v=(TextView)findViewById(R.id.fax);
v1=(TextView)findViewById(R.id.tit_fax);
keep this in globally then its work,no need to use View.VISIBLE,Keep the variable unique
Don't use this in your XML,because it get confused
android:visibility="visible"
