how disable rotation animation on clicking 'navigation drawer indicator' ( hamburger icon) ? i'm using htc model on geny motion emulator(1 gb ram). on clicking navigation drawer icon, there slight lag on nav panel sliding (opening , closing). so,i think, disabling animation make sliding smoother. (i'm using navigation drawer default template) you can use setdrawerslideanimationenabled(boolean) enable or disable drawer arrow animation when drawer position changes. example of be: // installs drawer toggle drawertoggle = new actionbardrawertoggle(this, drawerlayout, r.string.drawer_open, r.string.drawer_close); // disables animation drawertoggle.setdrawerslideanimationenabled(false);
