Question

In my application  I have 2 LinearLayout s right above each other  Via a menu option  I want to be able to make the bottom one disappear  and have the top one drop down over the disappeared LinearLayout   The problem is  I have no idea on how to do this in Java   It doesn t have to be animated  I want to hide the Layout on return of another activity  the menu   in OnActivityResult  The menu activity sets a boolean on which I check in OnActivityResult  and according to it s value I determine if I need to hide or show the bottom Layout      Only change value if it is different from what it was  if mUseVolumeButtonAsPTT    resultData getBoolean  UseVolumeButtonAsPTT         mUseVolumeButtonAsPTT   resultData getBoolean  UseVolumeButtonAsPTT        if  mUseVolumeButtonAsPTT              Hide lower LinearLayout        else              Show lower LinearLayout            Can anybody give me a hint or a link on how I should do this

Kotlin Solution view isVisible   true view isInvisible   true view isGone   true     For these to work  you need to use androidx and import  import androidx core view isVisible    or isInvisible isGone  Kotlin Extension Solution If you d like them to be more consistent length  work for nullable views  and lower the chance of writing the wrong boolean  try using these custom extensions     Example view hide    fun View  show         if  this    null  return     if   isVisible  isVisible   true    fun View  hide         if  this    null  return     if   isInvisible  isInvisible   true    fun View  gone         if  this    null  return     if   isGone  isGone   true    To make conditional visibility simple  also add these  fun View  show visible  Boolean        if  visible  show   else gone      fun View  hide hide  Boolean        if  hide  hide   else show      fun View  gone gone  Boolean   true        if  gone  gone   else show

You can call view setVisibility View GONE  if you want to remove it from the layout   Or view setVisibility View INVISIBLE  if you just want to hide it   From Android Docs      INVISIBLE      This view is invisible  but it still takes up space for layout purposes  Use with setVisibility int  and android visibility       GONE      This view is invisible  and it doesn t take any space for layout purposes  Use with setVisibility int  and android visibility
