The easiest way to remove it is to make your Activity extend the Activity class and not the AppCompatActivity.

删除它的最简单方法是使Activity扩展Activity类而不是AppCompatActivity。

That is do something like this:

这是做这样的事情:

public class MyActivity extends Activity {

}

What did you try?

你尝试了什么?

Just add this in styles.xml

只需在styles.xml中添加它即可

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

</style>

And

android:theme="@style/AppTheme"

in AndroidManifest.xml in application section.

在应用程序部分的AndroidManifest.xml中。

In your style file (res/values/styles.xml) is declared the style of your project.

在您的样式文件(res / values / styles.xml)中声明了项目的样式。

For example

例如

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
            <!-- Customize your theme here. -->
    </style>

Change "Theme.AppCompat.Light.DarkActionBar" with "Theme.AppCompat.Light.NoActionBar"

使用“Theme.AppCompat.Light.NoActionBar”更改“Theme.AppCompat.Light.DarkActionBar”

like this

喜欢这个

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
            <!-- Customize your theme here. -->
    </style>

The same can be achieved for Dark themes.

黑暗主题也可以实现同样的效果。

If you're on Android Studio, you'll have a choice to change the Theme from the preview windows without any code.

如果您使用的是Android Studio,则可以选择从预览窗口更改主题而无需任何代码。

may be late but i found a way too just remove the following code from your xml layout

可能会迟到但我发现一种方法也只是从你的xml布局中删除以下代码

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>
