Highlights the last five lines with this error. When compiling displays the following:

 Error:(81, 25) error: no suitable constructor found for ActionBarDrawerToggle(MainActivity,DrawerLayout,int,int,int) constructor ActionBarDrawerToggle.ActionBarDrawerToggle(Activity,DrawerLayout,Toolbar,int,int) is not applicable (argument mismatch; int cannot be converted to Toolbar) constructor ActionBarDrawerToggle.<T>ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int) is not applicable (cannot infer type-variable(s) T (actual and formal argument lists differ in length)) where T is a type-variable: T extends Drawable,DrawerToggle declared in constructor <T>ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int)

    Try this

     mDrawerToggle = new ActionBarDrawerToggle( this, mDrawerLayout, android.R.string.ok, android.R.string.ok) { public void onDrawerClosed(View view) { supportInvalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { } };
    • This code is present, but the error is still highlighted ( - Cyril
    • ??? I gave a slightly different code, not the one you have in question. You have a mistake in that you are using the wrong ones, in the wrong order or the wrong number of arguments in the constructor ActionBarDrawerToggle - JuriySPb ā™¦
    • Thank you, figured out - Cyril
