Set Round Corner image in ImageView

Question

I have searched more on websites and got many suggestions like below

• Changing background with custom style to set the corner radius and padding ( Getting image as rectangle and background as rounded corner)

• Changing Given image to Bitmap by decoding the image and cropping functionality by passing this bitmap and width ( its taking more time to load)

I have checked the WhatsApp Chat history list and it has rounded corner images but its loaded with minimum time.

Could you please suggest me the best way to create listview template with rounded images as in WhatsApp?

I am expecting to change the image with rounded corner by setting the style details in xml page. (image width and height is 60 dp, also my listview having around 60 items)

How are you setting the ImageView? From resource or do you download the bitmap from somewhere else? – Viscardi

stackover flow already have an answer refer this #2460416 – Mogul

@bGorle: yes i tried this and its taking more time to load images – Ultramicroscope

use android.support.v4.graphics.drawable.RoundedBitmapDrawable – Chevy

Check this now we have ShapeableImageView to make circular or rounded imageView https://mcmap.net/q/50039/-imageview-rounded-corners-duplicate – Restrain

Answer 1

The Material Components Library provides the new ShapeableImageView.
Just use a layout like:

  <com.google.android.material.imageview.ShapeableImageView
      ...
      app:shapeAppearanceOverlay="@style/roundedCorners"
      app:srcCompat="@drawable/...." />

With the shapeAppearanceOverlay attribute you can apply a custom shape, in this case rounded corners:

  <style name="roundedCorners" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">xxdp</item>
  </style>

*Note: it requires at least the version 1.2.0-alpha03.

Answer 2

The answer from sats is worked. But RoundedBitmapDrawable cannot be applied to an ImageView with scaleType: centerCrop.

An updated.

If you are using Android API at level 21. We have a simple solution here.

1st, create drawable as background for the imageview

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="@android:color/white" />

<stroke
    android:width="1dp"
    android:color="@color/colorWhite" />
</shape>

Next, change ImageView's property setClipToOutline to true. And set rounded drawable as ImageView's background.

That's it.

In my demo, I using this method for rounded imageview. Can find it here cuberto's dialog

Attribute clipToOutline is only used in API level 31 and higher not 21 – Morley

@AbdulWaheed No, it added at 21, developer.android.com/reference/android/view/… – Quartering

Yes maybe you're right. The android studio was showing me this warning I don't know why. – Morley

Answer 3

Put imageView in CardView and set CornerRadius for CardView

<android.support.v7.widget.CardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:cardCornerRadius="8dp"
        app:cardElevation="0dp">

        <ImageView
            android:id="@+id/imgTourismHr"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scaleType="fitXY" />

    </android.support.v7.widget.CardView>

this is the only solution worked for me for transparent rounded corners – Tanner

Answer 4

you can use the standard API's provided by Google to create a circular ImageView.

ImageView imageView = (ImageView) findViewById(R.id.circleImageView);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(getResources(), bitmap);
roundedBitmapDrawable.setCircular(true);
imageView.setImageDrawable(roundedBitmapDrawable);

Also refer https://www.youtube.com/watch?v=zVC-YAnDlgk

Nolly

Thanks this look like works for me but the only problem I'm having is the second parameter of decodeResource. I have a imageUrl which loads the image. how do I achieve this in this case ? – Lapointe

Answer 5

See the rounded rectangle image Output with Rounded Corner border

Now to Set Rounded Rectangle Image with rounded Border.

You Can Simple Declare CardView inside CardView With app:cardCornerRadius="30dp", app:cardUseCompatPadding="true", app:cardElevation="0dp".

See the Below Xml Code

            <androidx.cardview.widget.CardView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                app:cardCornerRadius="30dp"
                app:cardUseCompatPadding="true"
                app:cardElevation="0dp"
                android:layout_margin="5dp"
                >
                <ImageView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:src="@drawable/temp"
                    android:scaleType="fitXY"
                    android:layout_gravity="center"
                    />
            </androidx.cardview.widget.CardView>

Change cardCornerRadius according to your need

<androidx.cardview.widget.CardView
    android:layout_width="120dp"
    android:layout_height="120dp"
    android:layout_gravity="center"
    app:cardCornerRadius="20dp">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/sample"
            android:scaleType="centerCrop"/>

    </LinearLayout>
</androidx.cardview.widget.CardView>

Answer 7

We can use the CardView widget that is provided by androidx for this problem solution.

The code is the following.

<RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content">
                <LinearLayout
                    android:id="@+id/avatar_layout"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginBottom="@dimen/padding_20"
                    android:background="@drawable/roundimage">

                    <androidx.cardview.widget.CardView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:orientation="vertical"
                        app:cardCornerRadius="50dp"
                        app:cardElevation="0dp">

                        <ImageView
                            android:id="@+id/avatar"
                            android:layout_width="100dp"
                            android:layout_height="100dp"
                            android:padding="@dimen/padding_5"
                            android:scaleType="fitXY"
                            android:src="@drawable/launch_icon" />

                    </androidx.cardview.widget.CardView>
                </LinearLayout>

                <ImageView
                    android:id="@+id/avatar_edit"
                    android:layout_width="@dimen/padding_30"
                    android:layout_height="@dimen/padding_30"
                    android:src="@drawable/edit_profile_btn"
                    android:clickable="true"
                    android:layout_alignEnd="@id/avatar_layout"/>
</RelativeLayout>

Answer 8

Did you check 9 patch technique in android?

If you are trying to create something like whats app bubble chats with rounded corners I suggest you to use this technique instead of using XML Bitmap Decoder.

here is an example : Link

according to this example you can use 9 patch generators to create your own custom shapes and bitmap images that automatically resize to accommodate the contents of the view and the size of the screen. Selected parts of the image are scaled horizontally or vertically based indicators drawn within the image.

kotlin solution:

class RoundedCornerImageView(context: Context?, attrs: AttributeSet?) : 
androidx.appcompat.widget.AppCompatImageView(context, attrs) {

private val path: Path? = Path()
private var cornerRadius: Int = 0
private var roundedCorner: Int = 0

init {
    val a: TypedArray = context!!.obtainStyledAttributes(attrs, R.styleable.RoundedCornerImageView)
    cornerRadius = a.getDimensionPixelSize(R.styleable.RoundedCornerImageView_radius, 0)
    roundedCorner = a.getInt(R.styleable.RoundedCornerImageView_corner, 0)
    a.recycle()
}

override fun onDraw(canvas: Canvas?) {
    if (!path!!.isEmpty){
        canvas!!.clipPath(path)
    }
    super.onDraw(canvas)
}

override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) {
    super.onSizeChanged(w, h, oldw, oldh)
    setPath()
}

private fun setPath() {
    path!!.rewind()

    val radii = FloatArray(8)

    Log.d(TAG, "setPath : $roundedCorner")

    when(roundedCorner){
        0 ->{
            // all side
            for(i in 0 until 8)
                radii[i] = cornerRadius.toFloat()
        }

        1 ->{
            //top left
            radii[0] = cornerRadius.toFloat()
            radii[1] = cornerRadius.toFloat()
        }

        2 ->{
            //top right
            radii[2] = cornerRadius.toFloat()
            radii[3] = cornerRadius.toFloat()
        }

        3 ->{
            //bottom right
            radii[4] = cornerRadius.toFloat()
            radii[5] = cornerRadius.toFloat()

        }

        4 ->{
            //bottom left
            radii[6] = cornerRadius.toFloat()
            radii[7] = cornerRadius.toFloat()

        }

        5 ->{
            //left
            radii[0] = cornerRadius.toFloat()
            radii[1] = cornerRadius.toFloat()
            radii[6] = cornerRadius.toFloat()
            radii[7] = cornerRadius.toFloat()

        }

        6 ->{
            //right
            radii[2] = cornerRadius.toFloat()
            radii[3] = cornerRadius.toFloat()
            radii[4] = cornerRadius.toFloat()
            radii[5] = cornerRadius.toFloat()

        }

        7 ->{
            //top
            radii[0] = cornerRadius.toFloat()
            radii[1] = cornerRadius.toFloat()

            radii[6] = cornerRadius.toFloat()
            radii[7] = cornerRadius.toFloat()

        }
    }  
    path.addRoundRect(RectF(0F,0F,width.toFloat(),
                      height.toFloat()),
                      radii,Path.Direction.CW)
}

}

don't forget to add this in your attr.xml file

<declare-styleable name="RoundedCornerImageView">
    <attr name="radius" format="dimension"/>
    <attr name="corner">
       <flag name="topLeft" value="1"/>
       <flag name="topRight" value="2"/>
       <flag name="bottomRight" value="3"/>
       <flag name="bottomLeft" value="4"/>
       <flag name="left" value="5"/>
       <flag name="right" value="6"/>
       <flag name="top" value="7"/>
       <flag name="bottom" value="8"/>

Use the ShapeableImageView from material package

<com.google.android.material.imageview.ShapeableImageView
        android:layout_height="150dp"
        android:layout_width="150dp"
        android:layout_margin="10dp"
        android:scaleType="centerCrop"
        app:srcCompat="@drawable/photo"
        app:shapeAppearanceOverlay="@style/circleImageStyle"/>

And add the below style in themes.xml

   <style name="circleImageStyle" parent="ShapeAppearance.MaterialComponents.MediumComponent">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>

Quick solution for anyone using Glide in loading network images, which is using RequestOptions.circleCropTransform():

Glide.with(context)
     .load(imageUrl)
     .apply(RequestOptions.circleCropTransform())
     .into(object : CustomViewTarget<ImageView, Drawable>(imageView) {
            override fun onLoadFailed(errorDrawable: Drawable?) {
            }
            override fun onResourceCleared(placeholder: Drawable?) {
            }
            override fun onResourceReady(resource: Drawable, transition: Transition<in Drawable>?) {
                imageView.setImageDrawable(resource)
            }
