创建自定义外观的android活动

Question

I have seen certain apps in play store that doesn't take full screen like the normal activities do. They take a portion of screen. I have tried to search a solution but as I am newbie, I don't know the exact words that are used for such kind of activities. How can I create such activities? Regards

Answer 1

These are using Transparent Activity . You can kind how to create transparent activities here and here .

For example

You could apply a transparent theme to the required activity. Create a new style in /res/values/style.xml

<resources>
<style name="iosTransparent">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:backgroundDimEnabled">false</item>
</style>
</resources>

Now Apply theme

<activity android:name="IosNotActivity" android:theme="@style/iosTransparent"></activity>

Make a layout like this (it is just a sample)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/opLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:gravity="bottom">

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/ios" 
        android:scaleType="fitXY"/>

</LinearLayout>

Gives output like this(this is scaled since i used just an image, you can use any layout you want)
