Hide part of activity_main.xml if keyboard is open (Android) -


i have following activity_main.xml shown @ bottom. there, coordinatorlayout , 2 linearlayouts occur. first linearlayout1 has edittext input text, button send it. second 1 has 2 other buttons.

if click edittext, keyboard shows , makes in linearlayout2 barely visible. so, want hide both buttons in last layout when keyboard open.

i found out use android:windowsoftinputmode="statehidden" may trick, in connection activities in androidmanifest.xml. want use inner second linear layout. tried use there, no success.

in addition, handle in xml , keep mainactivity-code clean. possibilities this? 

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android">     ...     <android.support.design.widget.coordinatorlayout>         <android.support.v7.widget.recyclerview/>     </android.support.design.widget.coordinatorlayout>      <linearlayout>         <edittext/>         <button android:id="@+id/button_send"/>     </linearlayout>      <linearlayout>         <button/>         <button/>     </linearlayout>  </linearlayout>

we had same issue in past have put observable on full layout object try , let me know

/*hide button when keyboard open*/ view.getviewtreeobserver().addongloballayoutlistener(new viewtreeobserver.ongloballayoutlistener() {     @override     public void ongloballayout() {         rect r = new rect();         view.getwindowvisibledisplayframe(r);          int heightdiff = view.getrootview().getheight() - (r.bottom - r.top);          if (heightdiff > 244) { // if more 100 pixels, keyboard...             //ok know keyboard up...             buttonlayout.setvisibility(view.gone);           } else {             //ok know keyboard down...             buttonlayout.setvisibility(view.visible);           }     } });
