App - Activity - Translucent Blur

Translucent Blur

テーマを使って透明にしています。 背景のボケは getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND); で指定

Java

普通

    protected void onCreate(Bundle icicle) {
        // Be sure to call the super class.
        super.onCreate(icicle);

        // Have the system blur any windows behind this one.
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
                WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

        // See assets/res/any/layout/translucent_background.xml for this
        // view layout definition, which is being set here as
        // the content of our screen.
        setContentView(R.layout.translucent_background);
    }

Layout

AndroidManifest.xml - テーマの指定
        <activity android:name=".app.TranslucentBlurActivity"
                android:label="@string/activity_translucent_blur"
                android:theme="@style/Theme.Transparent">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.SAMPLE_CODE" />
            </intent-filter>
        </activity>


styles.xml - 背景色指定
    <!-- Variation on our application theme that has a transparent
         background; this example completely removes the background,
         allowing the activity to decide how to composite.  Also here we
         force the translucency ourself rather than making use of the built-in
         translucent theme. -->

    <style name="Theme.Transparent">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Translucent</item>
        <item name="android:windowBackground">@drawable/transparent_background</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:colorForeground">#fff</item>
    </style>

完全に透明
colors.xml
