Bitmap with rounded convers - android

I want to make Bitmap rounded, but in result bitmap I have only left-top , and left-bottom corners become rounded. How to make all corners rounded?
#Override
public Bitmap transform(Bitmap source) {
Bitmap output = Bitmap.createBitmap(source.getWidth(), source.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int cornerSizePx = 28;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, source.getWidth(), source.getHeight());
final RectF rectF = new RectF(rect);
// prepare canvas for transfer
paint.setAntiAlias(true);
paint.setColor(0xFFFFFFFF);
paint.setStyle(Paint.Style.FILL);
canvas.drawARGB(0, 0, 0, 0);
canvas.drawRoundRect(rectF, cornerSizePx, cornerSizePx, paint);
// draw source
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(source, rect, rect, paint);
return output;
}
Here is my source bitmap:
Here is result Bitmap
But I expected this:

Make Custom ImageView
Create Java class name CutomImageView.
Paste Following Code into that class.
public class CustomImageView extends ImageView {
public static float radius = 25.0f;
public CustomImageView(Context context) {
super(context);
}
public CustomImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onDraw(Canvas canvas) {
//float radius = 36.0f;
Path clipPath = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
clipPath.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(clipPath);
super.onDraw(canvas);
}}
In layout use this
<your package name.CustomImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/thumbimg"
android:layout_marginTop="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:visibility="gone"
/>

<?xml version="1.0" encoding="utf-8"?>
<item android:state_pressed="true">
<shape >
<solid android:color="#color/colorPrimaryDark"/>
<corners
android:radius="30dp"/>
</shape>
</item>
<item android:state_focused="true" >
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#color/colorPrimaryDark"/>
<corners
android:radius="30dp"/>
</shape>
</item>
<item android:state_focused="false" >
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#color/colorPrimary"/>
<corners
android:radius="30dp"/>
</shape>
</item>
<item android:state_pressed="false" >
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#color/colorPrimary"/>
<corners
android:radius="30dp"
/>
</shape>
</item>
put this code inside a new drawable file then use this new drawable file as a background of your image

How to draw segment of circle at the bottom of view [android]?

My activity should look like this:
I'm not sure what's the best way to show the segment of the circle between top and bottom views.
I'd like to avoid saving the segment as image.
Is there a way to show it using drawable xml (I've tried to achieve this using oval, but I don't know how to make is so "flat")?
Maybe drawing on canvas?
I think option 3 is the best, you can control exactly what you're drawing but you don't loose OOP karma points
OPTION 1
You can create a custom View for your top View and implement the drawing yourself like this, I'm subclassing RelativeLayout here but you can subclass whatever View you want
public class CurveBgRelativeLayout extends RelativeLayout {
public CurveBgRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
private Path path;
private Paint paint;
#Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setStyle(Paint.Style.FILL);
paint.setColor(0xffff0000);
path = new Path();
float horizontalOffset = w * .8f;
float top = -h * .8f;
float bottom = h;
RectF ovalRect = new RectF(-horizontalOffset, top, w + horizontalOffset, bottom);
path.lineTo(ovalRect.left, top);
path.arcTo(ovalRect, 0, 180, false);
path.setFillType(Path.FillType.INVERSE_EVEN_ODD);
}
#Override
protected void onDraw(Canvas canvas) {
if (path != null)
canvas.drawPath(path, paint);
super.onDraw(canvas);
}
}
and then in your xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.CurveBgRelativeLayout
android:layout_width="match_parent"
android:background="#ffffffff"
android:layout_height="0dp"
android:layout_weight="1"/>
<View
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#ffff0000"
/>
</LinearLayout>
OPTION 2
You can create an xml drawable as a background for your top View, the only problem here is that the horizontal stretch of the circle is given with a size in dp, so it's not relative to the View's size
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:height="40dp"
android:gravity="bottom">
<shape android:shape="rectangle">
<solid android:color="#ffff0000" />
</shape>
</item>
<item
android:width="500dp"
android:height="60dp"
android:gravity="bottom|center_horizontal"
android:top="-40dp">
<shape android:shape="oval">
<solid android:color="#ffffffff" />
</shape>
</item>
<item
android:height="30dp"
android:bottom="30dp"
android:gravity="bottom">
<shape android:shape="rectangle">
<solid android:color="#ffffffff" />
</shape>
</item>
</layer-list>
OPTION 3
public class CurveBottomDrawable extends Drawable {
private Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
private Path path = new Path();
public CurveBottomDrawable(int color) {
paint.setStyle(Paint.Style.FILL);
paint.setColor(color);
}
#Override
public void draw(#NonNull Canvas canvas) {
paint.setStyle(Paint.Style.FILL);
paint.setColor(0xffff0000);
path.reset();
Rect bounds = getBounds();
float horizontalOffset = bounds.width() * .8f;
float top = -bounds.height() * .8f;
float bottom = bounds.height();
RectF ovalRect = new RectF(-horizontalOffset, top, bounds.width() + horizontalOffset, bottom);
path.lineTo(ovalRect.left, top);
path.arcTo(ovalRect, 0, 180, false);
path.setFillType(Path.FillType.INVERSE_EVEN_ODD);
canvas.drawPath(path, paint);
}
#Override
public void setAlpha(#IntRange(from = 0, to = 255) int alpha) {
paint.setAlpha(alpha);
}
#Override
public void setColorFilter(#Nullable ColorFilter colorFilter) {
paint.setColorFilter(colorFilter);
}
#Override
public int getOpacity() {
return PixelFormat.TRANSPARENT;
}
}
and then set it programmatically
myView.setBackground(new CurveBottomDrawable(0xffff0000));

How can I set a background image with rounded corners

I want to create a background that is an image and also give it rounded corners. I have the following code. the background image shows but there is no rounded corners.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<corners android:radius="20dp" />
</shape>
</item>
<item>
<bitmap
android:src="#drawable/tabs_pattern_diagonal"
android:tileMode="repeat" />
</item>
</layer-list>
I have tried changing the order of the times but it made no difference
edit
I dont have an imageview. this layerlist is being applied as a background to a linearlayout
You can use this library if you don't want to implement rounded corners yourself.
You can try following :
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
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 = 12;
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;
}

You can also refer to article by Romain Guy
try this:
<item>
<shape android:shape="rectangle" android:padding="10dp" >
<corners
android:bottomRightRadius="15dp"
android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp"/>
</shape>
</item>
<item>
<bitmap
android:src="#drawable/tabs_pattern_diagonal"
android:tileMode="repeat" />
</item>
</layer-list>

Image not cropping

I am setting a background image to LinearLayout like this:
1.back_xml:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/back" >
</item>
<item>
<shape>
<solid/>
<stroke android:width="1dip" android:color="#225786" />
<corners android:radius="10dip"/>
<padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
</shape>
</item>
2. tile.xml
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/pie_chart_background"
android:tileMode="repeat">
</bitmap>
now I am setting the back.xml as a background to LinearLayout it works fine.
I need to have a image with rounded corners and also a border to it.But i only have the border with rounded corners and not the image what is the problem in my code am i missing something?
this is how my image looks:
After spending hours of time behind your issue, finally I achieved, hope now it will give you same result as you want, please go through below code and let me know whether its works or not?
Pass appropriate parameter to below function to get rounded corner with your desire color border.
public static Bitmap getRoundedCornerImage(Bitmap bitmap, int cornerDips, int borderDips, Context context) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int borderSizePx = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (float) borderDips,
context.getResources().getDisplayMetrics());
final int cornerSizePx = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (float) cornerDips,
context.getResources().getDisplayMetrics());
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
paint.setAntiAlias(true);
paint.setColor(0xFFFFFFFF);
paint.setStyle(Paint.Style.FILL);
canvas.drawARGB(0, 0, 0, 0);
canvas.drawRoundRect(rectF, cornerSizePx, cornerSizePx, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
paint.setColor((Color.RED)); // you can change color of your border here, to other color
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth((float) borderSizePx);
canvas.drawRoundRect(rectF, cornerSizePx, cornerSizePx, paint);
return output;
}
main.xml

try your back.xml some thing like like this instead of giving a rectangle background image.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#ff00ff >

<item>
<shape android:shape="rectangle" >
<solid/>
<stroke android:width="1dip" android:color="#225786" />

Another alternative to what Raj has posted is to use a background image with transparency at the corner.
The BEST solution, as your background is simple, is to use a 9-patch, which is the Android-native solution to the majority of background images: http://developer.android.com/guide/topics/graphics/2d-graphics.html#nine-patch, which is similar in style to how some website backgrounds are drawn.
Android also has it's own 9-patch creator bundled with the sdk: http://developer.android.com/tools/help/draw9patch.html, so it's easy enough to edit your own png files, then apply the 9-patch to the layout. The advantage of 9-patches is that they also handle the resizing the UI for you, meaning you won't encounter as many problems when using your app on different screens
Use your shape in combination with an image with rounded corners.
You can use AndroidQuery to load the image with rounded corners.
See http://code.google.com/p/android-query/wiki/ImageLoading#Rounded_Corner
String url ="http://www.vikispot.com/z/images/vikispot/android-w.png";
ImageOptions options = new ImageOptions();
options.round = 15;
aq.id(R.id.image).image(url, options);
I think you should have done it like this.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="#color/back" />
<stroke android:width="1dip" android:color="#225786" />
<corners android:radius="10dip"/>
<padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
</shape>
</item>
If the background is not a color but it is a bitmap, you should follow this beautiful guide
http://www.curious-creature.org/2012/12/11/android-recipe-1-image-with-rounded-corners/
Solution 1
create a 9-patch image for the border. the middle of the image should be transparent.
use a RelativeLayout as a parent and put your image LinearLayout at the bottom. set the border 9-patch as the background to another linear layout and place it on top of the image LinearLayout. Then it will cover the corners and you will get the expected result.
Solution 2
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
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 = 12;
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;
}

Bitmap image with rounded corners with stroke

I have a image with sharp edges.
the 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">
</bitmap>
the back.xml
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/tile_mode" />
<item>
<shape>
<solid/>
<stroke android:width="1dip" android:color="#225786" />
<corners android:radius="10dip"/>
<padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
</shape>
</item>
layout.xml
<LinearLayout
android:id="#+id/frame1"
android:background="#drawable/back"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</LinearLayout>
I am setting the image as a background to this layout and drawing a border to it but the problem is the image is square with sharp edges and the border which I am drawing in the xml is rounded corners. So how to make the image also with rounded corners?
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));
Pass original bitmap to the following function and you will get a rounded bitmap as result :) . Hope this helps someone.
public Bitmap getRoundedBitmap(Bitmap bitmap) {
Bitmap resultBitmap;
int originalWidth = bitmap.getWidth();
int originalHeight = bitmap.getHeight();
float r;
if (originalWidth > originalHeight) {
resultBitmap = Bitmap.createBitmap(originalHeight, originalHeight,
Bitmap.Config.ARGB_8888);
r = originalHeight / 2;
} else {
resultBitmap = Bitmap.createBitmap(originalWidth, originalWidth,
Bitmap.Config.ARGB_8888);
r = originalWidth / 2;
}
Canvas canvas = new Canvas(resultBitmap);
final Paint paint = new Paint();
final Rect rect = new Rect(ConstsCore.ZERO_INT_VALUE,
ConstsCore.ZERO_INT_VALUE, originalWidth, originalHeight);
paint.setAntiAlias(true);
canvas.drawARGB(ConstsCore.ZERO_INT_VALUE, ConstsCore.ZERO_INT_VALUE,
ConstsCore.ZERO_INT_VALUE, ConstsCore.ZERO_INT_VALUE);
canvas.drawCircle(r, r, r, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return resultBitmap;
}
ok let's try in below way
<?xml version="1.0" encoding="utf-8"?>
<shape
android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="30dp"/>
<stroke android:width="2dp" android:color="#000000"/>
</shape>
<LinearLayout
android:id="#+id/frame1"
android:background="#drawable/corner_background"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background"
/>
</LinearLayout>
RobinHood's answer worked for me with one change due to an error I was receiving about variable assignment.
I had to change the line:
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
To this line:
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
Making my complete code this:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
TextView textViewTitle = (TextView) findViewById(R.id.MYTEXTIDHERE);
textViewTitle.setText("Some Text");
ImageButton imageButtonSetter = (ImageButton) findViewById(R.id.MYIMAGEIDHERE);
Bitmap myBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.MYIMAGENAMEHERE);
imageButtonSetter.setImageBitmap(getRoundedCornerBitmap(myBitmap, 40));
}
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(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}
Actually, there is a library that I made which meet your needs exactly, and you don't have to bother with those xml files.
https://github.com/pungrue26/SelectableRoundedImageView
With this open-source project, You can set different radii on each corners, and set borders(width and colors), and etc. like below. I hope it may help you.
try your back.xml something 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="#ffffffff"/>
<stroke android:width="3dp"
android:color="#ff000000"
/>
<padding android:left="1dp"
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
/>
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
I had a similar problem today only my image was a Google map. you actually have to hide the corners and the way to do that is to create a 9Patch as the following one:
and apply it as a background over all your layout or another layout covering your layout.
Take a look at the following link for more information:
Is there a way to implement rounded corners to a Mapfragment?
I have actully went to this site: http://www.sumopaint.com/app/
and painted it all by hand you can take my example and change the colors to your liking.
you would probably need the next one:
you can get more information on how to create 9Patchs in the following links:

And i have image button_blue_bg with gradient with 1px width.
When i set button background i get next image
As you can see i have background not clipped with rounded border.
How i need modificate xml for background gradient image be not outside border?
I understand why it happended, because i use layers - so this like sandwich- but i also programming on objective c, and there it's also use layers. But in Apple it's wotks fine.
i use this.... First a Layer for the basic definition, set this layer as backgound of your layout:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke android:width="0.2dp" android:color="#color/anycolor" />
<corners android:radius="10dp" > </corners>
</shape>
</item>
<item>
<bitmap android:src="#drawable/imgback" />
</item>
</layer-list>
i use this function for making round corners:
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
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 = 12;
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 ;
}
and finaly, the code in the activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
// i use a Relative Layout
RelativeLayout rl = (RelativeLayout) findViewById(R.id.rlmenu);
// Obtain then backgroud of RelativeLayout
LayerDrawable layer = (LayerDrawable) rl.getBackground();
// obtain the image set in the Layer
BitmapDrawable bg = (BitmapDrawable) layer.getDrawable(1);
// create a new BitmapDrawable from the function
Drawable d =new BitmapDrawable(getRoundedCornerBitmap(bg.getBitmap()));
// set the new roundcorner image in the layer
layer.setDrawableByLayerId(1, d);
rl.setBackgroundDrawable(d);
}
A 9-patch would be perfect for your situation
