How to make a corner radius in android

I am trying to make a gridview that will have an image and text underneath with a corner radius effect. While this seems impossible. Here is my xml activity that is holding the gridview:

<ScrollView
    android:layout_width="match_parent"
    android:fillViewport="true"
    android:layout_height="match_parent">
    <GridView
        android:id="@+id/gridview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:columnWidth="140dp"
        android:padding="5dp"
        android:layout_marginTop="10dp"
        android:numColumns="auto_fit"
        android:verticalSpacing="5dp"
        android:horizontalSpacing="5dp"
        android:stretchMode="columnWidth"
        android:gravity="center"/>
</ScrollView>

Here is the xml adapter:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:app="http://schemas.android.com/apk/res-auto"
              android:orientation="vertical"
              android:layout_height="wrap_content"
              android:padding="2dp"
              android:layout_margin="20dp"
              android:background="@drawable/grid_corner_radius"
              android:layout_width="wrap_content">
    <ImageView
        android:layout_width="200dp"
        android:background="@drawable/cat_life"
        android:layout_height="160dp"/>

    <TextView
        android:layout_width="200dp"
        android:layout_height="40dp"
        android:id="@+id/credit_textView"
        android:gravity="center"
        android:text="Life"
        android:textColor="#FFFFFF"
        android:background="@color/colorPrimary"
        android:textSize="15dp"/>
</LinearLayout>

And finally, here is the magic code for the radius corner:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android" >
            <solid android:color="#C0C0C0"></solid>
            <corners android:radius="15dp"></corners>
        </shape>
    </item>
</selector>

And the result is the same:

See image. The clear edge of the rectangle is visible. What is the possible solution?

You can encapsulate your xml adapter with CardView and set cornerRadius for it. It should work.

Add compile 'com.android.support:cardview-v7:24.2.0'

gradle to your app.



<android.support.v7.widget.CardView xmlns:android="https://schemas.android.com/apk/res/android"
xmlns:card_view="https://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="2dp"
android:layout_margin="20dp"
card_view:cardCornerRadius="4dp">
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:layout_height="match_parent"
          android:layout_width="match_parent">
<ImageView
    android:layout_width="200dp"
    android:background="@drawable/cat_life"
    android:layout_height="160dp"/>

<TextView
    android:layout_width="200dp"
    android:layout_height="40dp"
    android:id="@+id/credit_textView"
    android:gravity="center"
    android:text="Life"
    android:textColor="#FFFFFF"
    android:background="@color/colorPrimary"
    android:textSize="15dp"/>
      </LinearLayout>    
</android.support.v7.widget.CardView>

try this code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_height="wrap_content"
    android:padding="2dp"
    android:layout_margin="20dp"
    android:background="@drawable/corners_layout"
    android:layout_width="wrap_content">
    <ImageView
        android:layout_width="200dp"
        android:layout_height="160dp"
        android:background="@drawable/corners_image"/>

    <TextView
        android:layout_width="200dp"
        android:layout_height="40dp"
        android:id="@+id/credit_textView"
        android:gravity="center"
        android:text="Life"
        android:textColor="#FFFFFF"
        android:background="@drawable/corners_text"
        android:textSize="15dp"/>
</LinearLayout>

Use this style for your layout:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/colorPrimaryJob"/>
    <corners android:radius="20dp"/>
</shape>


Use this style for text view:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/colorBlue"/>
    <corners android:bottomLeftRadius="20dp" android:bottomRightRadius="20dp"/>
</shape>

Use this style to view images:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/colorPrimaryJob"/>
    <corners android:topLeftRadius="20dp" android:topRightRadius="20dp"/>
</shape>
