Error inflating class android.support.v7.widget.Toolbar?

I am trying to get Material Design for my App by following this method.

Whenever I run the App it shows the following error:

> Error inflating class android.support.v7.widget.Toolbar.

I checked whether I have added the appcompat properly. But it is all Correct to me. So please tell me what am I doing wrong ?

If you are using new androidx implementations, when typing Toolbar, the Studio will autocomplete it to android.support.v7.widget.Toolbar, but you should use androidx.appcompat.widget.Toolbar instead, otherwise you will get this error.

Sorry Guys. I have solved this Issue long ago. I did a lot of changes. So I can't figure out which one does the trick.

1. I have changed the id as suggested by Jared Burrows.

2. Removed my support library and cleaned my project and Re added it.

3. Go to File -> Invalidate Caches/Restart.

Hope it works.

This is how my code looks now

 </style>

This happened to me when I tried to use my older code in new android with androidx implementations. change your XML definition to;

<androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
            app:titleTextColor="@android:color/white" />

then in your java code;

import androidx.appcompat.widget.Toolbar;

I was able to solve this problem by replacing the following:

In the Toolbar layout, replace everything which is like this:

android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"

with

android:minHeight="@dimen/abc_action_bar_default_height_material"
android:background="@color/myColor"

I have solved this Issue by this blog:http://android-developers.blogspot.com/2014/10/appcompat-v21-material-design-for-pre.html

The problem is you use the wrong theme,you can choose theme that like Theme.AppCompat.NoActionBar, in my project,it works.

I hope to help you。

I had the same issue as i was using the 23.2.0 version of AppCompat Library. I updated the suppport library to 23.2.1 and the problem was solved.

This Issue of Toolbar has been resolved in 23.2.1

Please read this Google Blog post: http://android-developers.blogspot.com/2014/10/appcompat-v21-material-design-for-pre.html

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

Also, you are giving it the same "ID" twice, please remove the "id" from your include:

<include android:id="@+id/toolbar" layout="@layout/toolbar" />

I face the same problem but that was after I had updated to appcompatv23.2.0. I tried all the above suggestions but dint work. Then I proceeded to my Gradle file and replaced:

dependencies {
compile 'com.android.support:appcompat-v7:23.2.0’
compile 'com.android.support:design:23.2.0'

}

with:

dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
}

Rebuild the project and the issue was gone. It could be an issue with app compact v23.2.0, hopefully a better solution coming up so we can work with the new update.

Hope this helps. Thank you.

I have fixed this problem by modifying app build.gradle file.

For Gradle Plugin 2.0+

 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
    }  
 }  

For Gradle Plugin 1.5

 android {  
   defaultConfig {  

     generatedDensities = []  
  }  

  aaptOptions {  
    additionalParameters "--no-version-vectors"  
  }  
 } 

I know this is an old question, but I recently ran into this same issue. It ended up being a Proguard problem (when I set minifyEnabled to false it stopped happening.)

To stop it, with proguard enabled, I added the following to my proguard rules file, thanks to a solution I found elsewhere (after discovering that the problem was proguard)

-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

Not sure if they're necessary, but I also added these lines:

-keep class com.google.** { *; }
-keep interface com.google.** { *; }

I faced with same problem. Solution that worked for me. If you use v7.Toolbar you must use theme extended from Theme.AppCompat.* You can't use theme extended from android:Theme.Material.* because they have different style attributes.

Hope it will helpful.

To fix this problem . first you must add latestandroid-support-v7-appcompat from the \sdk\extras\android\support

1. Close the main project.
2. Remove the android-support-v7-appcompat .
3. Restart the Eclipse.
4. Add the android-support-v7-appcompat .
5. Clean,To build the project.
6. Then open the main project and build all the projects.
7. The error still remains. Restart eclipse. That's it.

That works for me and I will strongly recommend you to use Android Studio.

I removed these lines as below :

before :

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar1"
    android:layout_width="match_parent"
    android:layout_height="@attr/actionBarSize"
    android:minHeight="@attr/actionBarSize"
    android:layout_alignParentTop="true" >

after :

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar1"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_alignParentTop="true" >

Instead of "@attr/actionBarSize" put specific dimens it works for me.

This worked for me: Add compile 'com.android.support:appcompat-v7:21.0.3' to the gradle. Change the sdk target to 21. Hope it works for you!

For me it worked after I did:

• Cleaning solution.
• Deleting the app from the phone I've debugged it at.
• Closing Visual Studio.
• Deleting folders /bin/ and /obj/ in android projects.
• Launching solution again.

None of the above solutions worked for me.

I didn't have a toolbar in my project, but got the same error.

I cleaned up the project, uninstalled the app. Then I ran a gradlew build --refresh-dependencies, and found out there were some onclick events without corresponding code in the xml files.

I removed them, rebuilt the project, and it worked.

The dependencies didn't seem like were updated, but that's another story.

In the case of Xamarin in VS, you must add

Theme = "@style/MyThemesss"

to youractivity.cs.

I add this and go on.

In my case I was getting this error in Inflation exception on Imageview, in the lower versions and lollipop OS.

I resolved this exception when moving all image file in drawable v-24 folder to drawable folder.

I had issues including toolbar in a RelativeLayout, try with LinearLayout. If you want to overlay the toolbar, try with:

 <RelativeLayout>

    <LinearLayout>
      --INCLUDE tOOLBAR--
    </LinearLayout>
 
    <Button></Button>

 </RelativeLayout>

I don't understand why but it works for me.

It is unclearly why this error happened with me but I solved. I used same layout, in-line or using include, both of them cause NPE error. So I think it's not layout issue.

I had an abstract class call BaseActivity extends ActionBarActivity which have initActionBar() method. I override and call this method in OnCreate of child class. Something like that:

android.support.v7.app.ActionBar mActionBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_book_appointment);
    
    // Inject View using ButterKnife
    ButterKnife.inject(this);
    
    // Init toolbar & status bar
    initActionBar();
}

@Override
protected void initActionBar() {
    super.initActionBar();

    setSupportActionBar(mToolBar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    mActionBar = getSupportActionBar();
    mActionBar.setDisplayHomeAsUpEnabled(true);
    mActionBar.setHomeButtonEnabled(true);
}

I HAD NPE ERROR WITH ABOVE CODE. I DON'T KNOW WHY I'M WRONG. I SOLVE BY BELOW CODE AND IT'S LOOK SAME.

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_book_appointment);
    ButterKnife.inject(this);

    setSupportActionBar(mToolBar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    mActionBar = getSupportActionBar();
    mActionBar.setDisplayHomeAsUpEnabled(true);
    mActionBar.setHomeButtonEnabled(true);

    initActionBar();
}

@Override
protected void initActionBar() {
    super.initActionBar();
}

In my case, a problem was in calling inflater.inflate(R.layout.some_layout, null). Null as ViewGroup parameter was the problem.

The solution to the problem for me was found in the XML document for my Main Activity. Originally my toolbar was <android.support.v7.widget.Toolbar. To resolve this I changed it to <android.widget.Toolbar. I do not know why this worked though. Does anyone have any insight as to why?

Problem was for pre-lolipop devices. I was able to solve this problem by replacing the following:

In the Toolbar layout, replace everything which is like this:

android:layout_height="?android:attr/actionBarSize"
android:background="?android:attr/colorPrimary"

with

android:layout_height="?attr/actionBarSize"
android:background="@color/colorPrimary"

For me, the error was that I had:

    <android:support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>

instead of:

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>

Specifically, I had a colon between "android" and "support" on the first line instead of a period.
