Android应用标头广告显示 [英] Android app masthead display

问题描述

我使用Android Studio 2.3.3创建了一个应用，选择空活动模板".创建它之后，我去了将背景色更改为诸如colorAccent之类的东西，并且还在colors.xml中将colorPrimary更改为colorAccent.

I have created an app using Android Studio 2.3.3, choosing Empty Activity Template. After its creation I went and changed the background color to something like colorAccent and I also changed the colorPrimary to colorAccent in colors.xml.

现在，当我运行该应用程序时，出现了以下模拟器显示.

Now, when I ran the app, following emulator display appeared.

如您所见，它显示我的应用程序名称，后跟黑线. 我不明白这条黑线是从哪里来的，我该如何摆脱呢?

As you can see, it displays my app name, followed by a dark line. I don't understand where this dark line has come from and how can I get rid of this?

但是，这条黑线在Android Studio设计模式下不会出现(请参见下面的屏幕截图).

However, this dark line does not appear in Android Studio design mode (see screenshot below).

推荐答案

这是操作栏的阴影，我的朋友 要删除此阴影，请在 res/values/style

it is shadow of action bar my friend to remove this shadow add below lines to your theme under res/values/style

<style name="MYTheme" parent="android:Theme.Holo.Light">
    <item name="colorPrimary">@color/colorWhite</item>
    <item name="colorPrimaryDark">@color/colorWhite</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowContentOverlay">@null</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

现在将其添加到清单文件中

now add this in manifest file this to your activity

<activity
android:name=".YourActivity"
android:theme="@style/MYTheme"/>

或尝试

    getSupportActionBar().setElevation(0);
