Do Not Request Window.FEATURE_ACTION_BAR And Set WindowActionBar To False In Your Theme To Use A Toolbar Instead

I'm having this issue when I applied the toolbar into my app and it crashed when I try to run the app.I used all previous post but no luck. Here is my code : Style.xml

Solution 1:

Your theme should look like this, and remove @style/:

<style name="MyMaterialTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
    ...
</style>

Then, do not define the theme in <application/> tag. Define it only with activity you want to use the material design theme, i.e. in <activity> tag.

If your activity extends PreferenceActivity, AppCompatActivity, or ActionBarActivity, which you want to begin the transaction with PreferenceFragment, change your theme to:

<style name="MyMaterialTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">true</item>
    ...
</style>

And remove this line from your Toolbar:

android:theme="@style/ToolBarStyle"
