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

Question

I have moved my app from using actionbar to toolbar however end up with the error (full error at bottom). My code:

My Activity:

public class MapsActivity extends ActionBarActivity implements LocationListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        ...
        mDrawerLayout.setDrawerListener(mDrawerToggle);

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

    if (toolbar != null)
    {
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setElevation(0); // or other
    }

        ...
    }
...
}

v21/style.xml

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- your app's theme inherits from the Material theme -->
    <style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
        <item name="windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
        <!-- Main theme colors -->
        <!--   your app branding color for the app bar -->
        <item name="android:colorPrimary">@color/primary</item>
        <!--   darker variant for the status bar and contextual app bars -->
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        <item name="android:navigationBarColor">@color/primary</item>

        <!--   theme UI controls like checkboxes and text fields -->
        <item name="android:colorAccent">@color/accent</item>
    </style>
</resources>

style.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

</resources>

gradle dependency

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:6.5.87'
    compile 'com.android.support:appcompat-v7:21.0.3'
}

my XML layout (after changes made by answer)

android:layout_width="match_parent"

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    />

<android.support.v4.widget.DrawerLayout

<!-- The main content view -->
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        </RelativeLayout>

<!-- The navigation drawer -->

Answer 1

replace your parent theme to @style/Theme.AppCompat.NoActionBar

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