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. Here are codes snippets:

styles.xml:

    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

<!--

        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.

回答1:

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

回答2:

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!
