addtopicactivity.java

public class addtopicfragment extends actionbaractivity {  private toolbar mtoolbar; @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_ma);     setcontentview(r.layout.activity_main);      mtoolbar = (toolbar) findviewbyid(r.id.toolbar);     setsupportactionbar(mtoolbar);     getsupportactionbar().sethomebuttonenabled(true);     getsupportactionbar().setdisplayhomeasupenabled(true);  }  } 

i want when activity starts fragment navigation drawer functionalities disabled completely. able remove drawer icon still when swipe left drawer comes picture.

thanks.

add inside addtopicactivity second activity. lock swipe

for lock

mdrawerlayout.setdrawerlockmode(drawerlayout.lock_mode_locked_closed); 

for unlock

mdrawerlayout.setdrawerlockmode(drawerlayout.lock_mode_unlocked);
