I'm working on a project in android studio, I'm trying to put the navigation drawer icon but I receive this error: 'cannot find symbol R.mipmap.if_drawer', I've tried placing it in the drawable but the same error is thrown for symbol 'R.drawable. ic_drawer'

After cleaning and rebuliding, I get the following message:

Error:(32, 26) error: no suitable constructor found for ActionBarDrawerToggle(MainActivity,DrawerLayout,int,int,int) constructor ActionBarDrawerToggle.ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int) is not applicable (cannot instantiate from arguments because actual and formal argument lists differ in length) constructor ActionBarDrawerToggle.ActionBarDrawerToggle(Activity,DrawerLayout,Toolbar,int,int) is not applicable (actual argument int cannot be converted to Toolbar by method invocation conversion) constructor ActionBarDrawerToggle.ActionBarDrawerToggle(Activity,DrawerLayout,int,int) is not applicable (actual and formal argument lists differ in length) where T is a type-variable: T extends Drawable,DrawerToggle declared in constructor ActionBarDrawerToggle(Activity,Toolbar,DrawerLayout,T,int,int)

Answer 1

on checking through the errors the IDE was throwing and suggestions it gave, the following was what I learnt: there are two constructors for the ActionBarDrawerToggle:

1. ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int drawerOpenContentDescription, int drawerClosedContentDescription)
2. ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int drawerOpenContentDescription, int drawerClosedContentDescription)

I used the 2nd constructor with 4 parameters and the navigation drawer worked fine without placing the 'ic_drawer' icon, instead, it is replaced with a back arrow.

Answer 2

There are two ActionBarDrawerToggle classes. Which is of

1. v4
2. v7

It is a common problem of ambiguity.

Solution

---

Remove third argument from the constructor solves the problem.

---

drawerListener = new ActionBarDrawerToggle(
this,
drawerLayout,
// R.drawable.ic_drawer, <== delete this argument
R.string.drawer_open,
R.string.drawer_close
) {
            @Override
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                Toast.makeText(MainActivity.this,"Drawer Open", Toast.LENGTH_LONG).show();
            }

            @Override
            public void onDrawerClosed(View drawerView) {
                super.onDrawerClosed(drawerView);
                Toast.makeText(MainActivity.this, "Drawer Closed", Toast.LENGTH_LONG).show();
            }
        };

After A lot of searching I have this.

Try to rebuild your project. And do a double check if you got the right name. Uppercases do also count for the name. And what is the extension of the file? If this above didn't help use this code:

drawerListener = new ActionBarDrawerToggle(this, drawerLayout,
                 getDrawable(R.mipmap.ic_drawer),
                 getString(R.string.drawer_open),
                 getString(R.string.drawer_close)){}

Answer 4

Please Clean Your Project & Rebuild .
