Android - Drawable with Rounded Corners at the Top Only

Android - drawable with rounded corners at the top only

Try giving these values:

 <corners android:topLeftRadius="6dp" android:topRightRadius="6dp"
         android:bottomLeftRadius="0.1dp" android:bottomRightRadius="0.1dp"/>

Note that I have changed 0dp to 0.1dp.

EDIT: See Aleks G comment below for a cleaner version

how to round only top two corners in my case

    <solid android:color="#FFFFFF" />
    <stroke
        android:width="3dp"

    <corners android:topLeftRadius="10dp" android:topRightRadius="10dp"
        android:bottomLeftRadius="0dp" android:bottomRightRadius="0dp"/>
    <padding
        android:bottom="0dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp" />
</shape>

Android: how to clip only top rounded corners

I've managed to get this working by creating a custom ViewOutlineProvider and using that instead of a background value

ViewOutlineProvider mViewOutlineProvider = new ViewOutlineProvider() {
    @Override
    public void getOutline(final View view, final Outline outline) {
        float cornerRadiusDP = 16f;
        float cornerRadius = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, cornerRadiusDP, getResources().getDisplayMetrics());
            outline.setRoundRect(0, 0, view.getWidth(), (int)(view.getHeight() + cornerRadius), cornerRadius);
        }
};
scrollView.setOutlineProvider(mViewOutlineProvider);
scrollView.setClipToOutline(true);

ImageView with only bottom or top corners rounded

Here is the another way to do this using Material Design ShapeableImageView

Create one theme for shape and cornerFamily

<style name="ImageView.Corner" parent="">
        <item name="cornerSizeTopRight">8dp</item>
        <item name="cornerSizeTopLeft">8dp</item>
        <item name="cornerSizeBottomLeft">0dp</item>
        <item name="cornerSizeBottomRight">0dp</item>
        <item name="cornerFamily">rounded</item>
    </style>

Now add ShapeableImageView in XML:

<com.google.android.material.imageview.ShapeableImageView
     android:layout_width="75dp"
     android:layout_height="75dp"
     app:layout_constraintBottom_toBottomOf="parent"
     app:layout_constraintStart_toStartOf="parent"
     app:layout_constraintTop_toTopOf="parent"
     app:srcCompat="@drawable/temp_product_image"
     app:shapeAppearanceOverlay="@style/ImageView.Corner"/>

I you want to full rounded ShapeableImageView:

<style name="ImageView.Round" parent="">
  <item name="cornerSize">50%</item>
</style>

Full Rounded Output:

That's it Happy Coding :).

How to create a layout with rounded corners on only the top or bottom half?

You can achieve this using material cardview. Here's the xml code of the full layout file:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<com.google.android.material.card.MaterialCardView
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_margin="10dp"
    app:cardCornerRadius="30dp"
    app:layout_constraintDimensionRatio="1:1"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <ImageView
            android:id="@+id/image"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:background="#406cca"
            android:visibility="visible" />

        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:background="#fb7500" />

    </LinearLayout>

</com.google.android.material.card.MaterialCardView>

</androidx.constraintlayout.widget.ConstraintLayout>

Remember, if the image is not there, just make the visibility of that particular imageview in your recyclerview to View.GONE in your code.

I hope you understood. If any queries, put a comment!

Here a pic of what this code looks like:
