Solution

I think is because your style is :

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

Try with:

<style name="AppTheme" parent="Theme.AppCompat.Light">

UPDATE:

Your logcat says:

This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

You must be calling Window.FEATURE_ACTION_BAR in your activity and you haven't post your java code and after looking at the code in your main_activity.xml I belive that you're using the toolbar, not the action bar, so maybe the answer I gave to you wouldn't work, and looking at this, this and this I think that you should put this instead of what I said before:

<item name="windowActionBar">false</item>
