Hexagon shaped ProgressBar

I am trying to make a game where a user gains experience points and his level increases as shown in the image below.
I was thinking of achieving this with the use of progress bar,but I am not able to make a progress bar with the shape of a Hexagon.
The yellow line should increase as the users points increase.
Can anyone give me ideas on how I can achieve this??(I tried Custom ProgressBar,but it did not work.)
Thanks.

I managed to change the code that Nilesh mentioned and made a progressbar which did not have any curves.
This works fine for me.
Now I just have to figure out how to insert the image inside the progressbar. :p

I am unable to use circle image view in android studio

I have added dependence compile 'de.hdodenhof:circleimageview:2.0.0'
my xml file is

still I am getting runtime exception
error inflating class on this line "de.hdodenhof.circleimageview.CircleImageView"

In your xml Layout use like below
<com.example.myproject.CircularImageView
android:id="#+id/profile_pic_round"
android:layout_width="#dimen/width_150dp"
android:layout_height="#dimen/height_150dp"
android:layout_gravity="center"
android:layout_margin="#dimen/margin_all_side_20dp"
android:src="#drawable/provider" />
Then in your java file initialize your imageview regularly like below:
ImageView profilePictureImg = (ImageView)
view.findViewById(R.id.profile_pic_round);
And you can use this class in your utility package or wherever you want:
import android.content.Context;

int w = getWidth(), h = getHeight();

canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {

if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius, false);
else
finalBitmap = bitmap;
Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
finalBitmap.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, finalBitmap.getWidth(), finalBitmap.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#000000"));

android triangle shape background not visible in imageview

I want to give a triangle background for the imageview in the application.The width is 40dp and height 23dp for the imageview.But it doesnot show the background.I changed the width and height of imageview to match parent.Then the background was visible.
Below is the drawable for creating triangular shape.

display image from url in rounded imageview android

I want to display my images in listview where the imageview is rounded, i serached in the net and in stackoverflow i just found that they use bitmap or i dont like to use it because i'm getting my information from webservice. is there any method or exemple to display it in this way.
this is how i display my images rectangle border
mLoader.DisplayImage(mylink + ArrayListComment.get(position).getImage(), holder.imageView);
}
if(ArrayListComment.get(position).getImage().contains(".png") {
mLoader.DisplayImage(ArrayListComment.get(position).getImage(), holder.imageView);
}

For rounded ImageView use RoundedImageView.
For display image from url use Picasso.

Create a new rounded.xml under drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<stroke
android:width="10dp"
android:color="#FFffffff" />
<solid android:color="#00000000" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
</item>
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke
android:width="10dp"
android:color="#FFffffff" />
<solid android:color="#00000000" />
<corners android:radius="30dp" />
</shape>
</item>
</layer-list>
and use it in your xml image view like this:
android:src="#drawable/rounded" and set the image background as you want it to be, it will be in a rounded shape
I hope this will help

Yes, you can od it by customizing your Imageview. Please check out my customImageview class Which may help you.enter code here.

#Override
protected void onDraw(Canvas canvas) {

}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(),
Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2 + 0.7f,
sbmp.getHeight() / 2 + 0.7f, sbmp.getWidth() / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}

Try this,
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.RectF;
import android.graphics.Bitmap.Config;
import android.graphics.PorterDuff.Mode;
public class ImageHelper {
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;
}
}
You will have to customise your image loader.
EDIT:
If you dont want to create a copy of a bitmap, you can use a bitmap shader.
See this blog,
http://www.curious-creature.com/2012/12/11/android-recipe-1-image-with-rounded-corners/
See the RoundedImageView for implementation.

Try this link
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if(bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(),
sbmp.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xffa19774;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2+0.7f, sbmp.getHeight() / 2+0.7f,
sbmp.getWidth() / 2+0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(android.graphics.PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;

rounded Image has black square around it

i have a rectangular image that i convert to a circle, then i set that image to the imageview. however i get a black square around the circular image. I need it to match the rest of the layout which is white.Can anyone explain why?
the layout below is part of a much larger layout that is used as the layout for the listview. I tried this code alone in a different app and it worked fine. The default color of the xml layout was white in that app so maybe it is still drawing the square but i just cant see it? The default color of the xml in my original app is black. could that be causing the problem?
here is part of the layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="horizontal" >
<RelativeLayout
