我想为我的活动设置半透明背景,但是按钮和图像等活动的内容应该正常显示。
我正在使用minSdkVersion 17,我的活动扩展了AppCompatActivity。
我应该使用什么样的样式功能来实现我的目标?

Add the following style in your res/values/styles.xml file (if you don’t have one, create it.) Here’s a complete file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
</resources>
(The value @color/transparent is the color value #00000000 which I put in the res/values/color.xml file. You can also use @android:color/transparent in later Android versions.)
Then apply the style to your activity, for example:
<activity android:name=".SampleActivity" android:theme="@style/Theme.Transparent">
...
</activity>

您可以将活动背景更改为 -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#27ffffff"/>
