Question

I try to create not full screen Activity with transparency around it and use this layout XML:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:id="@+id/containerPageContainer">


    <FrameLayout
        android:id="@+id/informationContainer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" >

        <LinearLayout
            android:id="@+id/myContainer"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="center_horizontal"
            android:background="@drawable/rounder_corners"
            android:orientation="vertical"
            android:padding="10dp" >

        </LinearLayout>

    </FrameLayout>

</merge>  

And for rounded corners:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">

    <solid android:color="#FFFFFFFF" />
    <corners android:radius="10dp" />

</shape>

But have received this result with defects on corners, bottom and top sides:

Help me to fix it please.

Answer 1

I have found solution:

1) Create theme XML in res/values/:

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
  <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>

2) Rounded corners style drawable/rounded_corners.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">

    <solid android:color="#FFFFFFFF" />
    <corners android:radius="10dp" />

</shape>

3) Activity XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/qrCodeContainer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center_horizontal"
        android:background="@drawable/rounder_corners"
        android:orientation="vertical"
        android:padding="15dp"
        android:layout_margin="6dp" >

    </RelativeLayout>

</RelativeLayout>

4) Describe Activity in project manifest XML:

<activity
    android:name=".view.ViewCodeActivity"
    android:label="@string/app_name"
    android:theme="@style/Theme.Transparent">

</activity>
