android - Why it won't detect onTouch? -

my actionbar called pressing "menu button" this. , it's working fine

@override public boolean onkeydown(int keycode, keyevent event) { if(keycode == keyevent.keycode_menu){     if (mactionbar.isshowing()) {         mactionbar.hide();     }     else {         mactionbar.show();     } }else if(keycode == keyevent.keycode_back){     webview  mywebview = (webview)findviewbyid(r.id.webview1);     mywebview.goback(); } return true; }        

when user touches screen while actionbar shown, actionbar should disappear.
won't detect ontouch event. why?

public boolean ontouch(view view, motionevent event) {       switch(event.getaction() & motionevent.action_mask) {       case motionevent.action_down:             if (mactionbar.isshowing()) {                 mactionbar.hide();             }       case motionevent.action_up:         break;       case motionevent.action_pointer_up:         break;       }       return true;     } 

update:

view.ontouchlistener mdelayhidetouchlistener = new view.ontouchlistener(){ public boolean ontouch(view view, motionevent event) {       switch(event.getaction() & motionevent.action_mask) {       case motionevent.action_down:             if (mactionbar.isshowing()) {                 mactionbar.hide();             }       case motionevent.action_up:         break;       case motionevent.action_pointer_up:         break;       }       return true;     }  }; 

it still won't work:(

change return value false

 return false;
