Remove shadow below actionbar
提问by Micha? K
I use actionbarsherlock. The piece of code below is responsible for changing it's background to a custom one.
我使用 actionbarsherlock。下面的一段代码负责将其背景更改为自定义背景。
<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.ActionBar">
<item name="background">@drawable/actionbar_bg</item>
<item name="android:background">@drawable/actionbar_bg</item>
<...>
</style>
<style name="Theme.MyApp" parent="@style/Theme.Sherlock.Light">
<item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
<item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
<..>
</style>
And it works for actionbarsherlock (on versions below honeycomb). But in ICS I have a shadow below actionbar which I don't want. What is the style item to make it disappear?
它适用于 actionbarsherlock（在蜂窝以下的版本上）。但是在 ICS 中，我不想要的操作栏下方有一个阴影。让它消失的样式项是什么？

In order to remove the shadow add this to your app theme:
为了去除阴影，将其添加到您的应用主题中：
<style name="MyAppTheme" parent="android:Theme.Holo.Light">
<item name="android:windowContentOverlay">@null</item>
</style>
UPDATE:As @Quinny898 stated, on Android 5.0 this has changed, you have to call setElevation(0)on your action bar. Note that if you're using the support library you must call it to that like so:
更新：正如@Quinny898 所说，在 Android 5.0 上这已经改变了，你必须调用setElevation(0)你的操作栏。请注意，如果您正在使用支持库，则必须像这样调用它：
getSupportActionBar().setElevation(0);
回答by Sloosh
For Android 5.0, if you want to set it directly into a style use:
对于Android 5.0，如果你想直接设置成样式使用：
<item name="android:elevation">0dp</item>
and for Support library compatibility use:
和支持库兼容性使用：
<item name="elevation">0dp</item>
Example of style for a AppCompat light theme:
AppCompat 灯光主题的样式示例：
<style name="Theme.MyApp.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<!-- remove shadow below action bar -->
<!-- <item name="android:elevation">0dp</item> -->
<!-- Support library compatibility -->
<item name="elevation">0dp</item>
</style>
Then apply this custom ActionBar style to you app theme:
然后将此自定义 ActionBar 样式应用于您的应用程序主题：
<style name="Theme.MyApp" parent="Theme.AppCompat.Light">
<item name="actionBarStyle">@style/Theme.MyApp.ActionBar</item>
</style>
For pre 5.0 Android, add this too to your app theme:
对于 5.0 之前的 Android，也将其添加到您的应用主题中：
<!-- Remove shadow below action bar Android < 5.0 -->
<item name="android:windowContentOverlay">@null</item>

On Android 5.0 this has changed, you have to call setElevation(0) on your action bar. Note that if you're using the support library you must call it to that like so:
在 Android 5.0 上，这已更改，您必须在操作栏上调用 setElevation(0)。请注意，如果您正在使用支持库，则必须像这样调用它：
getSupportActionBar().setElevation(0);
It's unaffected by the windowContentOverlay style item, so no changes to styles are required
它不受 windowContentOverlay 样式项的影响，因此不需要更改样式

I have this same problem, and I have successfully solved this problem. All you have to do is just change the elevation to 0 floating point value in that activity in which you want to remove the elevation.
我有同样的问题，我已经成功解决了这个问题。您所要做的就是在要删除高程的活动中将高程更改为 0 浮点值。
If you want to change it in an activity called MyActivity.javaso you have to get the ActionBarfirst.
如果您想在名为MyActivity.javaso的活动中更改它，则必须获得第ActionBar一个。
First import the ActionBarclass
首先导入ActionBar类
import android.support.v7.app.ActionBar;
after importing you have to initialize a variable of action bar and set its elevation to 0.
导入后，您必须初始化操作栏的变量并将其高程设置为 0。
private ActionBar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
.
.
toolbar=getSupportActionBar();
toolbar.setElevation(0);
.
.
}
