setSupportActionBar toolbar cannot be applied to (android.widget.Toolbar) error

Question

I've been looking for an answer and I've tried many possible solutions, but nothing seems to work..

I'm trying to setup a Material Action Bar following this tutorial.

Here's my code:

tool_bar.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/ColorPrimary"
    android:elevation="4dp">

</android.support.v7.widget.Toolbar>

activity.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF">
    <!-- The main content view -->
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include
            android:id="@+id/app_bar"
            layout="@layout/tool_bar" />
    </RelativeLayout>
    <!-- Navigation Drawer -->
    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="220dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="#1C1C1C"
        android:divider="@android:color/darker_gray"
        android:dividerHeight="1dp" />

</android.support.v4.widget.DrawerLayout>

And finally my activity.java:

import android.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toolbar;


public class rutaActivity extends ActionBarActivity {

private Toolbar toolbar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_ruta);

        getSupportActionBar().hide();//Ocultar ActivityBar anterior

        toolbar = (Toolbar) findViewById(R.id.app_bar);
        setSupportActionBar(toolbar); //HERE'S THE PROBLEM !!!!

Error:

setSupporActionBar (android.support.v7.widget.Toolbar) in ActionBarActivity cannot be applied to (android.widget.Toolbar)

How can I fix this?

In your Activity.java import android.support.v7.widget.Toolbar instead of android.widget.Toolbar:

import android.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.Toolbar;


public class rutaActivity extends AppCompactActivity {

private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ruta);

    getSupportActionBar().hide();//Ocultar ActivityBar anterior

    toolbar = (Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar); //NO PROBLEM !!!!

Update:

If you are using androidx, replace

import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;

with newer imports

import androidx.appcompat.widget.Toolbar;
import androidx.appcompat.app.AppCompatActivity;

Use `AppCompatActivity` instead of `ActionBarActivity` as Google has depreciated it. — nyxaria, Aug 09 '15 at 17:25

In using toolbar you should extends AppCompatActivity and

import android.support.v7.widget.Toolbar

Extends `AppCompatActivity` gave me the clue I was missing. – Francisco Romero Aug 24 '16 at 11:53

For adding a ToolBar that supports Material Design, the official documentation directions are probably the best to follow.

Add the v7 appcompat support library.

Make your activity extend AppCompatActivity.

public class MyActivity extends AppCompatActivity {
  // ...
}

Declare NoActionBar in the Manifest.

<application
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"
    />

Add a toolbar to your activity's xml layout.

<android.support.v7.widget.Toolbar
   android:id="@+id/my_toolbar"
   android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
   ...
   />

Call setSupportActionBar in the activity's onCreate.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
    setSupportActionBar(myToolbar);
}

Note: You will have to import the following in the activity.

import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

Forgot to extend AppCompatActivity and was getting an Unresolved Reference on setSupportActionBar. Thanks! — Mike Miller, Oct 12 '17 at 20:10

With the addition of androidx in Studio 3.0+ the Toolbar compatibility is now in a new library, accessible like this

import androidx.appcompat.widget.Toolbar

Certify that your Manifest declaration includes android:theme="@style/AppTheme.NoActionBar" tag, like the following:

<activity
    android:name=".PointsScreen"
    android:theme="@style/AppTheme.NoActionBar">
</activity>

Adding import android.support.v7.widget.Toolbar to the import list resolve this issue.

Then add the toolbar widget layout file:

<android.support.v7.widget.Toolbar
    android:id="@+id/list_toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="?attr/actionBarTheme"
    />

In onCreate method of java code

//call to

Tootbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar);

ToolBar's name can easily be changed using

android:label="My Activity"

in your Manifest File. I just going through Manifest & found

android:label

Helps to change according to the specific activity, Hope you'll give it a try

I was using previously this code:

Toolbar toolbar =  findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

and extended AppCompatActivity also but I was getting the same error. So in place of using Toolbar class, I have imported the below class and it worked for me:

android.support.v7.widget.Toolbar
