android - How to make views visible per button click -

i developing app calculation. consists of horizontal linearlayout , each layout has 2 edit text , and spinner. want make in such way user can add layouts button click when needs add more details.

in xml set android:visibility="gone" , in java set onclick method make "gone" linear layout view.visible. worked makes linear layouts appear once click + button. want them appear 1 after other (one appear , others remain "gone" until click button again)

you can use layout inflater.

create resource file in add layout , widgets required e.g item_resource.xml

 <?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" >  <linearlayout     android:id="@+id/linear"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:orientation="vertical" />     <button     android:id="@+id/btn"     android:layout_width="wrap_content"     android:layout_height="wrap_content"      />    <!-- other layout elements required -->  </linearlayout> 

then inflate above layout pragmatically on onclick event

  layoutinflater inflater = (layoutinflater)context.getsystemservice   (context.layout_inflater_service);   view view = inflater .inflate(r.layout.item_resource,null);   button button =(button)view.findviewbyid(r.id.btn);   button.settext("  ");   // set value 

add view main layout e.g

 linearlayout mylayout=(linearlayout)findviewbyid(r.id.xx);  mylayout.add(view);
