v7 widget toolbar not showing, why?

I am so close. I have the android studio project set up correctly with libs, the project compiles, and the emulators and device run the app. I am trying to get rid of the bottom button popup menu of older devices and replace with v7 appcompat toolbar. The old action bar is gone but the menu inflate still inflates to the old popup menu.
I start off using a splashscreen then the app main shows the database view activity. This means I have to dynamically load the toolbar.
My thinking now is the only place I have left to work out is the styles/themes or the order of setcontent(this) to display the main app/database view screen.
Also I dont have the correct emulator for the HTC evo device so the device buttons dont show. I believe this is why alot of developers post that the toolbar doesnt show. When I install apk on real device i can the use the menu button. This is how I am able to see that the menu is not in the toolbar. The emulator shows no buttons plus no toolbar so a developer on an emulator of newer devices would never see this.
I hope this enough to go on for any one to catch my pitfall here.
Thanks in advance.

public class TableMainLayout extends RelativeLayout {
public final String TAG = "TableMainLayout.java";

I have maybe the answer : you just get your toolbar before setContentView() method...
Just try this :
setContentView(new TableMainLayout(this));
Toolbar LrToolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(LrToolBar);
//getSupportActionBar().setDisplayShowHomeEnabled(true);
//LrToolBar.setNavigationContentDescription(getResources().getString(R.string.app_name));
Hope it will help you

Make your Toolbar layout like thie:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:background="#2196f3"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:minHeight="200dp" />
and in your Activity code replace the Toolbar LrToolBar = (Toolbar) findViewById(R.id.toolbar); with the:
Toolbar toolbar = LayoutInflater.from(this).inflate(R.layout.toolbar_layout_name, null)
setSupportActionBar(toolbar);
Hope it works.

Try this:
<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>
<item name="windowActionModeOverlay">true</item>
<item name="windowActionBar">false</item> //see this line
<item name="android:windowNoTitle">true</item>
</style>
Try setting <item name="windowActionBar">false</item>
I hope this helps!

you should create android resource directory with menu name then inside menu create action_bar.xml like this
<item
android:id="#+id/action_bar_refresh"
android:icon="#drawable/ic_refresh"
app:showAsAction="always"
android:title="test"/>
then in your activity override onCreateOptionMenu like below
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.action_bar,menu);
return super.onCreateOptionsMenu(menu);
}

Why my android application does not honor its style when deployed on actual device?

I have written an application for android API 14. When I am trying to run this app on emulator using Galaxy Nexus API 22, it shows fine, with all the colors and styles that I have programmed for. This is the screenshot:
But when I try to run it on my Asus Fonpad 7 that runs Android 5, it seems that non of my styles are honored. The application uses the default UI. Screenshot is as follows:
Can anyone help me with this? Please do let me know if any code snippets are required, since I am new to Android.

Update:
I installed the same application on Asus Fonpad 7 with Android 4.4.3 and Galaxy S3 with Android 4.3 and one both it was showing fine, with all the layouts customized. Any idea now?

try changing the style.xml to its default values given below, I guess your problem may be in the custom #drawables/resource_values you are using in style.xml
<resources>
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->

Why does Activity display Title yet by default?

From some doucment , I know ActionBarActivity display app title by default. I create a Activity with eclipse, I have set android:theme as android:Theme.Light, I find the Activity still display Title by default, why?

Try setting this to your activity declared in the manifest:
android:theme="#android:style/Theme.NoTitleBar"

//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//set content view AFTER ABOVE sequence (to avoid crash)
this.setContentView(R.layout.your_layout_name_here);
Be certain to put it before the call to setContentView(R.id.x), otherwise it will crash. The reason wasn't immediately obvious to me. 08-13 12:47:33.561 E/AndroidRuntime( 9125): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.myapp/com.myapp.SplashActivity}: android.util.AndroidRuntimeException: requestFeature() must be called before adding content

How can I get a multiline custom title on android?

I am working on a xamarin project (has no relevance here as far as I can tell - the android layout properties are the same)
I am using Window.SetFeatureInt (WindowFeatures.CustomTitle, ...) to set the title (2 "columns". I wish to make two rows of text though for my title. Is this possible? I have not had much success. I have an upper left, upper right and lower left and lower right TextViews to set.
My previous attempts have ended up with the TextViews overwriting each other.

Here I am designing a XML file with an image, text for title & button. This is the XML file. U can use it however you want, for a complete application or perticular activity.
In case of activity add this activity's theme tag. For multi line just use text view in side the below linear layout, set it as multline true.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="35dip"
android:gravity="center_vertical"
android:background="#android:color/darker_gray">
<ImageView
android:id="#+id/header"
android:background="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Window Text"
android:textColor="#android:color/black"
android:textStyle="bold"/>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
Create a theme in Custom_theme.xml,
<resources>
<style name="CustomWindowTitleBarBG">
<item name="android:background">#323331</item>
</style>
<style name="TitleBarTheme" parent="android:Theme">
<item name="android:windowTitleSize">35dip</item>
<item name="android:windowTitleBackgroundStyle"> #style/CustomWindowTitleBarBG</item>
</style>
Modify the AndroidManifest.xml file as follows for applying custom theme
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#style/TitleBarTheme" >
<activity
android:name=".CustomWindowTitle"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Now in main java file add “requestWindowFeature(Window.FEATURE_CUSTOM_TITLE)” &
“getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title)”
This is the code snippet for CustomWindowTitle.java
package com.example.android;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
public class CustomWindowTitle extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
}
}
