android - match_parent doesn't work for custom actionbar -

i try implement custom action bar. here xml:

<?xml version="1.0" encoding="utf-8"?> <framelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/action_bar">      <textview         android:layout_width="match_parent"         android:layout_height="match_parent"         android:text="test "/> </framelayout> 

and here java code:

public class customactionbaractivity extends appcompatactivity {     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         android.support.v7.app.actionbar actionbar = getsupportactionbar();          actionbar.setdisplayshowcustomenabled(true);         actionbar.setdisplayoptions(android.support.v7.app.actionbar.display_show_custom);         actionbar.setdisplayhomeasupenabled(false);         actionbar.setdisplayshowhomeenabled(false);         actionbar.setdisplayuselogoenabled(false);          view customview = getlayoutinflater().inflate(r.layout.action_bar, null);         actionbar.setcustomview(customview);         toolbar parent = (toolbar) customview.getparent();         parent.setcontentinsetsabsolute(0, 0);      } } 

the result is:

here result "developer options" > "show layout bounds"

as @muhannad fakhouri in comment pointed out. needed add layout params programatically. layout params ignored if layout inflated without specifying parent. here updated code:

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         android.support.v7.app.actionbar actionbar = getsupportactionbar();          actionbar.setdisplayshowcustomenabled(true);         actionbar.setdisplayoptions(android.support.v7.app.actionbar.display_show_custom);         actionbar.setdisplayhomeasupenabled(false);         actionbar.setdisplayshowhomeenabled(false);         actionbar.setdisplayuselogoenabled(false);          view customview = getlayoutinflater().inflate(r.layout.action_bar, null);         customview.setlayoutparams(new framelayout.layoutparams(framelayout.layoutparams.match_parent, framelayout.layoutparams.match_parent));         actionbar.setcustomview(customview);         toolbar parent = (toolbar) customview.getparent();         parent.setcontentinsetsabsolute(0, 0);      }
