Unable to remove Action Bar in Android tabLayout

I'm trying to get rid of the ActionBar in an android app.
here's the manifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
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>
</application>
and here's the styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- 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">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>
</resources>
I did change the AppTheme style to NoActionBar, but the emulator still shows the action bar, What am I missing ?

it's because you are setting wrong theme for your app,AppTheme parent should remove action bar
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="AppThemeNoActionBar">
<!-- 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="AppThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
</resources>

Remove android:theme="#style/AppTheme.NoActionBar from MainActivity entry in the manifest and then run your app.

stupidly enough, I didn't take a look at the main activity xml, which included an AppBarLayout widget, so I removed it and rearranged the layout, and now no action bar appears

Setting the ActionBar background colour to other than colorPrimary in XML

I have found similar questions but the answers did not work. I do not want to change the colorPrimary.
The ActionBar is not a ToolBar, so it does not exist in the activity's layout XML. The following did not work, and the bakground was still set to colorPrimary.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
<!-- Customize your theme here. -->
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:statusBarColor">#color/colorBlack</item>
<item name="android:colorBackground">#color/colorBlack</item>
</style>
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:backgroundStacked">#color/colorBlack</item>
<item name="android:backgroundSplit">#color/colorBlack</item>
<item name="android:background">#color/colorBlack</item>
</style>
</resources>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>

Programmatically you can do
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#YOUR_COLOR")));

colorprimarydark only work for the mainactivity,what should i do with it

this is my manifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:supportsRtl="true"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<service android:name="com.amap.api.location.APSService" />
<activity
android:name=".MainActivity"
android:label=""/>
<activity
android:name=".QueryActivity"
android:label="" />
<activity
android:name=".LoginActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".RegistActivity" />
<activity
android:name=".TaskListActivity"
android:label="" />
<activity
android:name=".TaskWatcherActivity"
android:label="" />
<activity
android:name=".DetailsActivity"
android:label="" />
</application>
i have set the style in style:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="colorControlNormal">#color/cpb_white</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#android:color/white</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
&style-v21:
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:fitsSystemWindows">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:navigationBarColor">#android:color/transparent</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:textSize">15sp</item>
<item name="android:colorControlNormal">#color/cpb_white</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
but only the mainactivity's status bar is in colorprimarydark,other activities' statusbar is in the color of their layout's background. so how can i make colorprimarydark work for every activity's status bar

Very easy and useful library for Tint Color use this library in every Activity set you status color.

Try to Use android:theme="#style/AppTheme" in each and every activity.
I think you solve your problem.

finally, i used the library for Tint Color to solve the problem, p.s.thasks to Jhaman Das.
And i found that the attr of statusBarColor would cover the effect of colorpromarydark, it is the drawlayout that can have the ideal effect. willing to get further discussion on this problem.

How to make my app name appear on the android:actionBarStyle?

I not sure what is happening.
It is okay when it was default, the word on the actionbar is gone when I apply the style for actionbar.

support actionbar menu styling

How does one style the Android ActionBar overflow menu (background color, text color, custom drawables etc.)?
I've been trying to do this with the following styles, but nothing seems to be taking any effect. Any help would be greatly appreciated.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:actionBarWidgetTheme">#style/MyActionBar</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="android:textColor">#android:color/holo_blue_light</item>
<item name="android:actionBarItemBackground">#android:color/holo_green_light</item>
<item name="android:actionMenuTextColor">#android:color/holo_green_dark</item>
</style>
</resources>
TIA!
BTW minSdk set to 14
AndroidManifest is
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app1.app1">
<application android:allowBackup="true"
android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Do you call it on AndroidManifest.xml file?
Example in my style.xml
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:background">#color/green_dark</item>
<item name="android:titleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
</style>
<style name="MyTheme.ActionBar.TitleTextStyle" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/white</item>
<item name="android:textStyle">bold</item>
</style>
and in menifestfile
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher1"
android:label="#string/app_name"
android:theme="#style/CustomActionBarTheme" >
<activity.....
For implement click listener, you need create option menu for this case.
