Custom shaped Linearlayout with curved side in android

问题

I am trying to make a custom shaped linearlayout like below

I am trying to make only one side curved. Tried with corner radius but it doesn't give the same look as above.

Already tried this background shape as below :-

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#3F51B5" />

    <padding
        android:bottom="7dp"
        android:left="7dp"
        android:right="7dp"
        android:top="7dp" />

    <corners
        android:bottomLeftRadius="50dp"
        android:bottomRightRadius="50dp"
        android:topLeftRadius="0dp"
        android:topRightRadius="0dp" />
</shape>

it rounds only corners and on increasing the value shape is not preserved it gets too circular. I WANT CURVED line and not rounded corners

Create a shape file in drawable folder e.g: my_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
   <corners
      android:bottomLeftRadius="100dp"
      android:bottomRightRadius="100dp"
      android:topLeftRadius="0dp"
      android:topRightRadius="0dp" />
   <padding
      android:bottom="0dp"
      android:left="0dp"
      android:right="0dp"
      android:top="0dp" />
   <stroke
      android:width="0.5dp"
      android:color="@color/theme_red" />
  <solid android:color="@color/white" />
</shape> 

then add this shape in your layout as a background. e.g:

<LinearLayout
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:background="@drawable/my_shape"
     android:orientation="horizontal">             
</LinearLayout>

Its very late already but this is for future seekers. I think vector drawables are the most perfect solution for this. Use below vector as background to get custom shaped bottom curved layout.

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportHeight="100.0"
android:viewportWidth="200.0">
<path
    android:fillColor="#YOUR_FAVORITE_COLOR"
    android:pathData="M200,0H0v4.5h0v75.8h0c17.8,10.2 56,17.2 100.5,17.2c44.5,0 81.6,-7 99.5,-17.2h0V4.5h0V0z" />

what i did is create a drawable allowaccess_button_normal.xml

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

    <item>
        <shape android:shape="oval">
            <solid android:color="@color/colorPrimary"/>
        </shape>
    </item>

</selector>

Try below layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#fefefe"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:background="@color/colorPrimary"
        android:layout_height="110dp">
    </RelativeLayout>

    <ImageView
        android:layout_marginTop="85dp"
        android:src="@drawable/allowaccess_button_normal"
        android:layout_width="match_parent"
        android:layout_height="50dp" />


</RelativeLayout>

 <layer-lisxmlns:android="http://schemas.android.com/apk/res/android">

   <item  android:top="175dp">

    <shape android:shape="oval">

     <gradient
        android:angle="135"
        android:startColor="#f56f2c"
        android:endColor="#fa9f46"/>

   </shape>
  </item>


  <item android:bottom="40dp">

   <shape android:shape="rectangle">

    <gradient
        android:angle="135"
        android:startColor="#f56f2c"
        android:endColor="#fa9f46"/>

   </shape>
 </item>
</layer-list>

you can set the dimension in the value -dimension.xml fime and then set it in your xml of your linearlayout it will give the following like this

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
   android:color="#FFFF00" />
<padding android:left="7dp"
    android:top="7dp"
    android:right="7dp"
    android:bottom="7dp" />

just make a xml file in your drawable set the dimensio u need and then call it by your linear layout
