I am new to Android. Now I have a problem about drawing borders on LinearLayout. I draw borders by following codes.
public class Borders{
int w;
int h;
public Borders(int x, int y){
w = x;
h = y;
}
public void drawBorderInImg(Canvas canvas){
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setStrokeWidth(10);
paint.setColor(Color.BLACK);
canvas.drawLine(0, 0, w, 0, paint);
canvas.drawLine(w, 0, w, h, paint);
canvas.drawLine(w, h, 0, h, paint);
canvas.drawLine(0, h, 0, 0, paint);
}
}
I create a boolean value and use onclickListener() to control it. By default, the value is false, so there is no border on the screen.
#Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
// operate.refresh(ShapeData.figureList1);
Borders borders = new Borders(img01.getWidth(), img01.getHeight());
if(img01DrawOrNot){
borders.drawBorderInImg(canvas);
}
And then I do
img01.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(img01DrawOrNot){
img01DrawOrNot = false;
} else{
img01DrawOrNot = true;
}
}
});
I set android:clickable=true in xml. It actually works. But, I need to postInvalidate() it. In fact, I can't refresh it because it contains some random shapes, when I do postInvalidate(), all views will change. How can it change automatically? So when I click, it will appear and when I click again, it will disappear. Could someone help me? Cheers!
if you like, try this.
(create this layout in your drawable folder)
layout_border.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

I want to add shadow around circular imageView.
Here is my code.
I want to make like this image
This is my .xml file
check this image.
activity_main.xml

this is round_image.xml:
<?xml version="1.0" encoding="utf-8"?>

android:width="80dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
I try some code for shadow effect but it's not working.
Hope this will help you:)
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#color/gray"/>
<!--shadow Color-->
</shape>
</item>
<item
android:left="0dp"
android:right="0dp"
android:top="0dp"
android:bottom="3dp">
<shape android:shape="oval">
<solid android:color="#color/lightgrey"/>//Background Color
</shape>
</item>
</layer-list>
Change the background Color and Shadow color as you want..
It is way simpler than you think. Your ImageView needs to appear rounded based on an oval background, as it is squared by default. Then you need to include elevation, and it will show as you expected. You cannot set the oval background transparent as it won't allow for
shadow elevation.
this is drawable/white_oval.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#android:color/white"/>
</shape>
</item>
</layer-list>
Now in your imageview, I am skipping here how you include your image
<ImageView
android:id="#+id/alert_icon"
android:layout_width="#dimen/alert_icon"
android:layout_height="#dimen/alert_icon"
android:contentDescription="#string/your_shadow_rulez"
android:background="#drawable/white_oval"
android:elevation="#dimen/elevation_fab" />
of course make sure your image view both width and height match. The bigger the elevation the larger the shadow
see how simple and nice this looks
Create a circle_shadow.xml file and use this code it work good for me. Make changes the radius according to your requirement.
circle_shadow.xml
<!-- Drop Shadow -->
<item>
<shape android:shape="oval">
<padding
android:bottom="1dp"

Before answering I want to give some advice. You just have to put title of your question in Google. I tried to search like circular imageview with shadow android:
Without use of Library:
Change android:color="#BDBDBD" in shape tag.
Your round_image.xml will be like:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#BDBDBD" />
<corners android:radius="2dp"/>
<size
android:height="80dp"
android:width="80dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
Using Library:
Have you tried this CircularImageView
You can use this library or if you don't want to use then get some code from this library inner res folder.
Thank you.
Here, I share my best practice to show a shadow effect to a circular image/resource with some details.
The above example image's icon is 56dp x 56dp and is cropped with a zoomed view so it may not look attractive but the results will show good on an actual device under the naked eye.
The above example is delivered by using:
Some amount of elevation, to let shadow.
Provide margin to the view almost double of elevation to fit the shadow.
Ensure the parent view provides the space almost double of elevation to fit the shadow.
Create and use an OutlineProvider to create the shadow.
Now here we begin with the code.
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="#dimen/margin_14dp"> // Point no. 3
<androidx.appcompat.widget.AppCompatImageView
android:id="#+id/img"
android:layout_width="#dimen/margin_56dp"
android:layout_height="#dimen/margin_56dp"
android:layout_margin="#dimen/margin_14dp" // Point no. 2
android:elevation="#dimen/margin_8dp" // Point no. 1
android:src="#drawable/ic_bell" />
</FrameLayout>
Let's proceed to point no. 4, here is the OutlineProvider class for a Circular Outline.
import android.graphics.Outline;
import android.view.View;
import android.view.ViewOutlineProvider;
public class CircularOutlineProvider extends ViewOutlineProvider {
#Override
public void getOutline(View view, Outline outline) {
outline.setRoundRect(0, 0, view.getWidth(), view.getHeight(), (view.getWidth() / 2F));
}
}
We left to use the OutlineProvider in our Java/Kotlin class to do the magic at runtime.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
findViewById(R.id.img).setOutlineProvider(new CircularOutlineProvider());
End of Magic Session!
For more experience and enhance details, please read the official article.
Add this xml code in your drawable layout and add it in your background:

I know there are many questions but it do not work out for me so i am posting this question:
I a adding a circular Imageview to my application, and i want some elevation/shadow to it so that it worked on all Api not only after 21. so what should i do?
this is my code:
xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

/>
</RelativeLayout>
this is mybackground in drawable :
<?xml version="1.0" encoding="utf-8"?>

</shape>
this is my code :
public class MainActivity extends AppCompatActivity {
Bitmap bmp;
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bmp = BitmapFactory.decodeResource(getResources(), R.drawable.frames);
bmp = getroundedBitmap(bmp);
ImageView iv = (ImageView) findViewById(R.id.imageView);

}*/
}
private Bitmap getroundedBitmap(Bitmap bmp) {
int targetwidth = 250;
int targetheight = 250;
Bitmap targetBitmap = Bitmap.createBitmap(targetwidth,targetheight,Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(targetBitmap);
Path path = new Path();
path.addCircle(((float) targetwidth - 1) / 2, ((float) targetheight - 1) / 2, Math.min(targetwidth, targetheight) / 2, Path.Direction.CCW);
canvas.clipPath(path);

p.setColor(Color.WHITE);
canvas.drawBitmap(bmp, new Rect(0, 0, bmp.getWidth(), bmp.getHeight()), new Rect(0, 0, targetwidth, targetheight), null);
return targetBitmap;
}
}
Please help me out. i ma working in android studio
Elevation cannot work before API 21 but you can have a work around by help of shadows. Create a shadow (circular in your case) in your mybackground drawable itself. Use layer-list as the parent element and gradient to create the shadow layer inside it.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<gradient android:startColor="#d1c4e9"
android:endColor="#android:color/transparent"
android:angle="270"/>
</shape>
</item>
<item android:right="1dp" android:left="1dp" android:bottom="3dp">
<shape android:shape="oval">
<solid android:color="#673ab7"/>
</shape>
</item>
</layer-list>
We can take ImageView Inside CardView,and height and width match with cardView
try once,it will work.
I'm using this code to draw a half in my app:
<?xml version="1.0" encoding="utf-8" ?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:left="35dp"
android:top="40dp"
android:bottom="40dp"
android:right="0dp">
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" android:innerRadius="30dp" android:thickness="0dp">
<solid android:color="#color/transparent"/>
<stroke android:width="3dp" android:color="#color/White"/>
</shape>
</item>
</layer-list>
output :
but i need something like below :
how to draw this ?
I would suggest to draw it through code.
1- Create class MyView and put below code.
public class MyView extends View {
public MyView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
#Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
float width = (float) getWidth();
float height = (float) getHeight();
float radius;
if (width > height) {
radius = height / 4;
} else {
radius = width / 4;
}
Path path = new Path();
path.addCircle(width / 2,
height / 2, radius,
Path.Direction.CW);
Paint paint = new Paint();
paint.setColor(Color.BLACK);
paint.setStrokeWidth(5);
paint.setStyle(Paint.Style.FILL);
float center_x, center_y;
final RectF oval = new RectF();
paint.setStyle(Paint.Style.STROKE);
center_x = width / 2;
center_y = height / 2;
oval.set(center_x - radius,
center_y - radius,
center_x + radius,
center_y + radius);
canvas.drawArc(oval, 90, 180, false, paint);
}
}
2-Initialize this class inside you activity or fragment:-
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new MyView(this));
}
Your can use a rectangle shape .xml file and edit the corners on one side only.
Example:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size android:height="30dp"
android:width="30dp"/>
<solid android:color="#color/black"/>
<corners android:topLeftRadius="15dp"
android:bottomLeftRadius="15dp"/>
</shape>
You can use <clip /> drawable in order to cut-off part of your circle.
http://developer.android.com/guide/topics/resources/drawable-resource.html#Clip
this is how i created my semi circle in a drawable xml file.
<size
android:width="180dp"
android:height="90dp"></size>
<corners
android:topLeftRadius="200dp"
android:topRightRadius="200dp"></corners>
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<size
android:width="180dp"
android:height="90dp"></size>
<corners
android:topLeftRadius="200dp"
android:topRightRadius="200dp"></corners>
<stroke android:width="5px" android:color="#color/black" />
</shape>
I try to create imageview with rounded corners.i searched and found xml code
<?xml version="1.0" encoding="utf-8"?>
<solid android:color="#00ffffff" />
<padding
android:bottom="6dp"
android:left="6dp"
android:right="6dp"
android:top="6dp" />
<corners android:radius="12dp" />
<stroke
android:width="6dp"
android:color="#ffffffff" />
and this is a my imageview xml code
<ImageView
android:id="#+id/slidemenuuserimage"
android:layout_width="90dp"
android:layout_height="90dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="16dp"
android:layout_marginLeft="14dp"
android:background="#drawable/frame" />
i have one problem.when i added background image programmatically i receive divirent result.
slidemenuuserimage=(ImageView)findViewById(R.id.slidemenuuserimage);
slidemenuuserimage.setBackgroundResource(R.drawable.myuserimg);
this is a my result
how i can add padding left or right programmatically.in my option this is a my problem
if anyone knows solution please help me
You can also do this programatically
public Bitmap roundCornerImage(Bitmap raw, float round) {
int width = raw.getWidth();
int height = raw.getHeight();
Bitmap result = Bitmap.createBitmap(width, height, Config.ARGB_8888);
Canvas canvas = new Canvas(result);
canvas.drawARGB(0, 0, 0, 0);
final Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setColor(Color.parseColor("#000000"));
final Rect rect = new Rect(0, 0, width, height);
final RectF rectF = new RectF(rect);
canvas.drawRoundRect(rectF, round, round, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.raw_IN));
canvas.drawBitmap(raw, rect, rect, paint);
return result;
}
Use it like
slidemenuuserimage.setImageBitmap(roundCornerImage(BitmapFactory.decodeResource(getResources(), R.drawable.yourImage),50)
Try out this shape
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#00ffffff"/>
<stroke android:width="3dp"
android:color="#ffffffff"/>
<padding android:left="1dp"
android:top="1dp"
android:right="1dp"
android:bottom="1dp"/>
<corners android:radius="30px"/>
</shape>
Code is here
you need to set src image, not background. So use setImageResource() not setBackgroundResource()
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:
