rounded Imageview in android eclipse? - android

I rounded Image View but the picture of Image view not round?
I use eclipse and XML
What do I do? see this picture:

You can use this
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
RoundedBitmapDrawable circularBitmapDrawable = RoundedBitmapDrawableFactory.create(getResources(), bitmap);
circularBitmapDrawable.setCircular(true);
userImage.setImageDrawable(circularBitmapDrawable);

The problem with your ImageView is that your ImageViews background is Rounded but the Image you set in your android:src="" is not rounded, thats why you are getting a Image like that
I was looking for a rounded ImageView too a few days ago and i found this to make any ImageView rounded without using any Library
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP
&& drawable instanceof VectorDrawable) {
((VectorDrawable) drawable).draw(canvas);
b = Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas();
c.setBitmap(b);
drawable.draw(c);
}
else {
b = ((BitmapDrawable) drawable).getBitmap();
}
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
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 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(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
But if you want to use a Library check this out https://github.com/vinc3m1/RoundedImageView

Use image as .png format then only image background transparent and image show inside the round.

Anchor ImageView inside Collapsing Toolbar

Well I have implemented imageview to Collapsing toolbar using the answer provided by Sanjeet Ajnabee on Anchor ImageView to Collapsing Toolbar . The implementation worked fine but now what i want is to add the edit button inside the profile picture so that i can browse the gallery from that button. please help.
This is my code
public class FloatingActionImageView extends FloatingActionButton {
public FloatingActionImageView(Context context) {
super(context);
}
public FloatingActionImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public FloatingActionImageView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sBmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
float factor = smallest / radius;
sBmp = Bitmap.createScaledBitmap(bmp, (int) (bmp.getWidth() / factor), (int) (bmp.getHeight() / factor), false);
} else {
sBmp = bmp;
}
Bitmap output = Bitmap.createBitmap(radius, radius,
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, radius + 5, radius + 5);
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(radius / 2,
radius / 2, radius / 2, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(sBmp, rect, rect, paint);
return output;
}
#Override
protected void onDraw(#NonNull Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = null;
if (b != null) {
bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
} else {
BitmapDrawable bitmapDrawable = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
bitmapDrawable = ((BitmapDrawable) getResources().getDrawable(R.drawable.ic_hospital, null));
} else {
bitmapDrawable = ((BitmapDrawable) getResources().getDrawable(R.drawable.ic_hospital));
}
if (bitmapDrawable != null) {
bitmap = bitmapDrawable.getBitmap();
}
}
int w = getWidth();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
}
And this is my layout
<com.example.cripes.rsnepal.FloatingActionImageView
android:layout_height="100dp"
android:layout_width="100dp"
app:layout_anchor="#id/appbarProfile"
app:layout_anchorGravity="bottom|end"
android:src="#drawable/ic_hospital"
android:layout_margin="#dimen/fab_margin"
android:clickable="true" />

How to define a triangle layout like this image in android?

How to create a layout like shown in image?
I think you can use android:rotation="-45" to put over the image a crossed component and make this effect.
Use this code :
1. Create TriangleImageView.java class in Java folder :
public class TriangleImageView extends ImageView {
public TriangleImageView(Context ctx, AttributeSet attrs) {
super(ctx, attrs);
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
Bitmap finalBitmap;
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);
Paint paint = new Paint();
final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
finalBitmap.getHeight());
Point point1_draw = new Point(75, 0);
Point point2_draw = new Point(0, 180);
Point point3_draw = new Point(180, 180);
Path path = new Path();
path.moveTo(point1_draw.x, point1_draw.y);
path.lineTo(point2_draw.x, point2_draw.y);
path.lineTo(point3_draw.x, point3_draw.y);
path.lineTo(point1_draw.x, point1_draw.y);
path.close();
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawPath(path, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(finalBitmap, rect, rect, paint);
return output;
}
}
In Acitivity Use this code :
private imageViewTriangle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageViewTriangle=(ImageView)findViewById(R.id.imageView_triangle);
Bitmap icon = BitmapFactory.decodeResource(getResources(), R.drawable.images);
imageViewTriangle.setImageBitmap(icon);
}
Output is :
Modify it as your need.
Note : ImageView is define in comment because it give me trouble to improve formatting ..
As stated above you can restructure the custom image class as the code below
public class ProfileImageView extends AppCompatImageView{
public ProfileImageView(Context context) {
super(context);
}
public ProfileImageView(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
public ProfileImageView(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w,this.getLayoutParams().width,this.getLayoutParams().height);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius, int dimension_w, int dimension_h) {
Bitmap finalBitmap;
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(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
Paint paint = new Paint();
final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
finalBitmap.getHeight());
Log.e("Profile",""+dimension_w);
Point point1_draw = new Point(0, 0);
Point point2_draw = new Point(dimension_w, 0);
Point point3_draw = new Point(dimension_w, (dimension_h/2));
Point point4_draw = new Point(0, dimension_h);
Path path = new Path();
path.moveTo(point1_draw.x, point1_draw.y);
path.lineTo(point2_draw.x, point2_draw.y);
path.lineTo(point3_draw.x, point3_draw.y);
path.lineTo(point4_draw.x, point4_draw.y);
path.lineTo(point1_draw.x, point1_draw.y);
path.close();
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawPath(path, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(finalBitmap, rect, rect, paint);
return output;
}
}

Null Pointer Exception on Rounded Image View

I have designed a separate image view class for rounded image. But When I am fetching image from facebook (profile picture). It throws Null Pointer Exception.
Process: com.moblit.fooddragon, PID: 605
java.lang.NullPointerException

Adding white border and shadow to Custom Android ImageView

I know this question has been asked before but I have struggled to come up with a solution.
I have a custom ImageView with complete rounded corners which is done programmatically.
I have something like this
But I want to get to something like this:
Here is my custom ImageView class.
#SuppressLint("NewApi")
public class MLRoundedImageView extends ImageView {
private Context context;
public MLRoundedImageView(Context context) {
super(context);
this.context = context;
}
public MLRoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
}
public MLRoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
this.context = context;
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
#SuppressLint("NewApi")
public Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
float factor = smallest / radius;
sbmp = Bitmap.createScaledBitmap(bmp, (int)(bmp.getWidth() / factor), (int)(bmp.getHeight() / factor), false);
} else {
sbmp = bmp;
}
Bitmap output = Bitmap.createBitmap(radius, radius,
Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xffa19774;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, radius, radius);
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(radius / 2 + 0.7f,
radius / 2 + 0.7f, radius / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
I know there is just a few extra I need to add i don't want to recreate the entire class as my project is heavily depended on it.
Thanks in advance!
Use layer list:
http://developer.android.com/guide/topics/resources/drawable-resource.html#LayerList
Basically create a white circle with the dimension you want and use layer list to create it under the picture

How to convert ImageView into Rounded Shape?

I am using following code for converting ImageView into rounded iage, but gettin error at "Mode.SRC_IN" . Need help. Thank you in advance.
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;
}
Use this class:
public class RoundedImageView extends ImageView {
private Paint objPaint = new Paint();
public RoundedImageView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth(), h = getHeight();
Log.i("TAG", "Bitmap Width:" + w);
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
objPaint.setAntiAlias(true);
objPaint.setDither(true);
canvas.drawBitmap(roundBitmap, 0, 0, objPaint);
}
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(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
now in xml file:
<path to your class
android:id="#+id/iv_leaderboard_profile_icon"
android:layout_width="#dimen/lederboard_image_size"
android:layout_height="#dimen/lederboard_image_size"
android:src="#drawable/ic_launcher" />
here
path= com.example.view.RoundedImageView
something like that.
hope you understand, thank you.
Romain guy has an excellent blog post about achieving rounded corners on ImageViews here
For PorterDuffXfermode, you have to write import android.graphics.PorterDuffXfermode;
For Config.ARGB_8888, you have to write import android.graphics.Bitmap.Config;
Otherwise Direct press CTRL + SHIFT + O to organize imports.
A new class is introduced in android.support.v4. Which provides you the circled image which any customization.
RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(mContext.getResources(), bitmap);
roundedBitmapDrawable.setCornerRadius(pixels);
imageView.setImageDrawable(roundedBitmapDrawable);
I would recommend to make use of it.
