Error inflating class android.support.v7.widget.Toolbar in Android

Question

I'ved looked at a ton of SO questions and tried implementing them. Can't seem to figure this one one, it was working yesterday, but not anymore.

gradle:

android {
compileSdkVersion 23
buildToolsVersion "23.0.0 "

dexOptions {
    javaMaxHeapSize "4g"
}

defaultConfig {
    minSdkVersion 16
    multiDexEnabled true
    targetSdkVersion 23
}
dependencies {
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:cardview-v7:23.0.0'
compile 'com.android.support:design:23+'
compile 'com.android.support:multidex:1.0.1'
compile 'com.android.support:recyclerview-v7:23.0.0'

Answer 1

This is what worked specifically for me. My problem had nothing to do with themes but rather the right compile versions of the dependencies and targetSdkVersion. Updated the gradle file below. Changed the

Original Gradle

compile 'com.android.support:support-v4:24.0.0-alpha2'

Changed:

compile 'com.android.support:support-v4:23.0.0'

Essentially the issue was my this version of the library did not match with the others and the minsdkversion, so something didn't mesh well. Once i updated all the dependencies (specifically from google design library) to match each other, it worked.

Answer 2

<style name="AppTheme" parent="@style/Theme.AppCompat.NoActionBar">
  <item name="windowActionBar">false</item>
  <item name="android:windowNoTitle">true</item>
</style>

Try with this theme snip

Answer 3

I had a similar issue in the past. The android:theme was the issue, on the Toolbar or on the AppBarLayout.

Edit: code example

<android.support.v7.widget.Toolbar
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

Option2:

<style name="MyToolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">@color/colorPrimary</item>
</style>
