我不能在这里上传图像,所以这里是文件：

我的清单文件

    <activity
        android:name="com.application.DateList"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:screenOrientation="portrait"
        android:theme="@style/FullscreenTheme" >
    </activity>
</application>

</manifest>

我也试过这个,但同样的事情发生了

ColorDrawable draw = new ColorDrawable(R.color.grey);
getSupportActionBar().setBackgroundDrawable(draw);

我的颜色抽屉

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid
        android:color="@color/grey" />

</shape>

解决方法:

getSupportActionBar().setBackgroundDrawable(draw);

应该是,在你的情况下

getSupportActionBar().setBackgroundDrawable(getResources.getDrawable(R.drawable.your_drawable_name);

ColorDrawable的构造函数采用表示颜色的int,而不是颜色的id.使用instenad

ColorDrawable draw = new ColorDrawable(getResources().getColor(R.color.grey));

编辑：

关于style.xml,你需要带有和没有android前缀的项目：

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
   <item name="android:actionBarStyle">@style/ActionBarTheme</item>  
   <item name="actionBarStyle">@style/ActionBarTheme</item>
</style>

由于minSDK值,Lint可能会抱怨它.如果是,你可以添加工具：ignore =“NewApi”到具有android：前缀的项目.例如：

 <item name="android:actionBarStyle" tools:ignore="NewApi">@style/ActionBarTheme</item>
