How can I create curved view?

I am working on cinema tickets application and now I need to create a curved view with blur shadow like this :
Is there a way of achieving this?
I have tried rotating image in x axis (-45%) but it is not what i need

as per #naggab's comment you should include image for this
but also I try to achieve this using below code
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#color/white" />
<size
android:width="450dp"
android:height="110dp" />
</shape>
</item>
<item android:top="50dp">
<shape android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
</shape>
</item>
<item android:top="20dp">
<shape android:shape="oval">
<solid android:color="#color/colorPrimary" />
<size
android:width="450dp"
android:height="110dp" />
</shape>
</item>
<item android:top="50dp">
<rotate
android:fromDegrees="4"
android:toDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
</shape>
</rotate>
</item>
<item android:top="50dp">
<rotate
android:fromDegrees="-4"
android:toDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
</shape>
</rotate>
</item>
</layer-list>

Radius in making border is given from inside instead of outside?

I am using below XML for creating border for a TextView.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item android:bottom="1dp">
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item
android:bottom="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item
android:bottom="2dp"
android:left="2dp"
android:right="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<solid android:color="#color/white" />
<corners android:radius="#dimen/padding_4dp"/>
</shape>
</item>
</layer-list>
When I give radius as <corners android:radius="#dimen/padding_4dp"/>, it gives radius to corners but from inside, not from outside. So, as a result, corners remain sharp from outside. Like below:
Am I doing wrong somewhere?

Other items you have added in layer-list are missing corners, add it as below
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item android:bottom="1dp">
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
<corners android:radius="#dimen/padding_4dp"/>
</shape>
</item>
<item
android:bottom="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<solid android:color="#color/dark_gray" />
<corners android:radius="#dimen/padding_4dp"/>
</shape>
</item>
<item
android:bottom="2dp"
android:left="2dp"
android:right="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<solid android:color="#color/white" />
<corners android:radius="#dimen/padding_4dp"/>
</shape>
</item>

For the remaining two item also add a corner radius.

Android banner ribbon using shape

I am trying to figure out how I would stack shapes so I can create the following ribbon(Pink/White/Pink/White/Pink part). I will then be using this as a background for my textview.

I figured it out using a layer-list
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="2dp" android:height="2dp"/>
</shape>
</item>
<item android:top="2dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFFFF" />
<size android:width="1dp" android:height="1dp"/>
</shape>
</item>
<item android:top="3dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="20dp" android:height="20dp"/>
</shape>
</item>
<item android:top="23dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFFFF" />
<size android:width="1dp" android:height="1dp"/>
</shape>
</item>
<item android:top="24dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="2dp" android:height="2dp"/>
</shape>
</item>
</layer-list>
