ActionBar未在API 16中显示

Question

I'm a beginner, I have made an app which contains navigation drawer along with the action bar in mainactivity.It worked perfectly on API 23 but in API 16, action bar isn't showing up.I searched many links on "actionbar not displaying" but they were having problems below API 11/8.After API 11, I think AppCompat should work (which I have used) Here are images

Here is my styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <style name="AppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
        <item name="windowNoTitle">true</item>
    </style>
    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.portus.yehchina">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".RegistrationActivity"
            android:label="@string/title_activity_registration"
            android:theme="@style/AppTheme"></activity>
    </application>

</manifest>

At first , According to your requirement please remove this line from manifest

android:theme="@style/AppTheme.NoActionBar"

My Suggestion , Use Toolbar instead of ActionBar .
