How to Implement Rounded Corners to a Mapfragment

Is there a way to implement rounded corners to a Mapfragment?

I haven't tried this, but I'd put a view with rounded corners and a transparent middle on top of the mapView / mapFragment.

That is, put the mapFragment and the rounded corner view in a FrameLayout with both filling the FrameLayout, then make the middle of the rounded corner view transparent.

For further clarification, you could do it in a layout as follows:-

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

<fragment
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/mapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/rounded_background"
    android:orientation="vertical" >
</LinearLayout>

</FrameLayout>

The rounded_background is a 9-patch with rounded corners and a transparent middle. E.g.

Add rounded corners in border in Maps Fragment and remove the Fragment background

try add this line to RelativeLayout or fragment

android:background="@drawable/map_border_2"

I hope it will work with you

Yes, it possible. Cover the MapFragment with another layout, and set for this layout a 9-patch background, that will cover it the way you want, take a look at this question I asked on the same topic not long ago:

Adding transparent rounded corners to google map

Well I guess you have stumbled on this question I asked regarding the same topic:

Is there a way to implement rounded corners to a Mapfragment?

But in this case I needed a solid color corners. I don't see an easy way to perform what you
ask for. There is no way to added rounded corners to the map "out of the box" so you will need to cover those corners with some other texture, typically it would be a 9-patch texture, that could stretch accordingly to the screen size.

You can take a look at this blog post on 9-patchs I wrote and maybe try to create a
semi-transparent texture that will fit you needs:

Round corners of MapFragment and ConstraintLayout in CardView

Enclosing the mapview in a cardview and changing the radius of the cardview can be a nice shot.

<android.support.v7.widget.CardView
    android:layout_width="300dp"
    android:layout_height="350dp"
    app:cardCornerRadius="12dp">
    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:cameraZoom="13"
        app:liteMode="true"
        app:mapType="normal" />
</android.support.v7.widget.CardView>

I really think your view hierarchy is quite nested and will amount to redundancy...(Good use of one Constraint layout can yield same interface, you have about 3). I guess you have to work on that.

Besides, you can add some margin to the map..., shift it from the edges. ( I hope that is what you want to achieve )

Using a Layout to Make Rounded Corners affect on image

well, with FrameLayout or RelativeLayout you can easily stack a second layer on top of you imageview like:

<FrameLayout
    android:layout_width="60dp"
    android:layout_width="60dp">
    <ImageView android:id="@+id/myimage"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:src="@drawable/myrealimage" />
    <ImageView android:id="@+id/my_roundedcorner_overlay"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:src="@drawable/myoverlaywithroundedcornersandtransparentcenter" />
</FrameLayout>

however, be warned this causes overdraw and makes your layout more complex.

You could also set the real image as a background to you ImageView and the overlay as the ImageViews src, however don't set a padding in this case (also loading images from the web with a library probably won't work anymore)

Cleanest solution is to create a custom widget extending ImageView and override its onDraw method, paint to the canvas using a bitmapshader, similar to http://www.curious-creature.org/2012/12/11/android-recipe-1-image-with-rounded-corners/ pretty much the same, but do it once and reuse as often as you want.

Bitmap image with rounded corners with stroke

This is one of solution in which you have to make round to your main layout background and inside keep your imageview with your desire image:

something like below:

back.xml

This will make your image to round corner

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
     <stroke android:width="1dp" android:color="#dd7b7a"/>
     <corners android:bottomRightRadius="10dp" android:bottomLeftRadius="10dp" 
     android:topLeftRadius="10dp" android:topRightRadius="10dp"/> 
     <solid android:color="#dd7b7a"/>
 </shape>

tile_mode.xml

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/background"
android:tileMode="repeat" />

layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
<LinearLayout 
     android:padding="4dip"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/back"
    android:gravity="center_horizontal"
    >
<LinearLayout  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
   android:background="@drawable/tile_mode"
    />
</LinearLayout>  
</LinearLayout>

After digging lots, I came across on of solution which already posted on stackoverflow

Changing Image as Rounded Corner

How to make an ImageView to have rounded corners

step1@

main.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        tools:context=".MainActivity" >

        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"

          />

    </RelativeLayout>

Step2@

Make one function which make rounded to your bitmap using canvas.

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int pixels) {
        Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap
                .getHeight(), Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final int color = 0xff424242;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
        final RectF rectF = new RectF(rect);
        final float roundPx = pixels;

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);

        return output;
    }

step3@

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageView image=(ImageView)findViewById(R.id.image);

        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.testing);

    image.setImageBitmap(getRoundedCornerBitmap(bitmap, 20));
