Android magnify view and draw as bitmap

I've a camera and from this I take a photo and save a bitmap. Overlayed to this, there's a view pager, with different layouts. When I take a photo, I want to save the current overlayed layout too.
The problem is that photo and layout are both saved, the layout fix correctly in the bitmap area, but it's smaller in respect as was in the preview camera. I need to magnify the layout (to look as it was before to the photo) and to save it in my bitmap.
Before to take photo:
After (it's ok that the button is still there, it's just a test):
My code:
Bitmap cameraBitmap = BitmapFactory.decodeByteArray
(data, 0, data.length);
int wid = cameraBitmap.getWidth();
int hgt = cameraBitmap.getHeight();
bitmap = Bitmap.createBitmap
(wid, hgt, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawBitmap(cameraBitmap, 0f, 0f, null);
ViewPager pager = (ViewPager) main_activity.findViewById(R.id.pager);
ScreenSlidePagerAdapter a = (ScreenSlidePagerAdapter) pager.getAdapter();
ScreenSlidePageFragment currFrag = (ScreenSlidePageFragment) a.instantiateItem(pager, a.getFocusedPage());
View currView = currFrag.getView();
Rect rect = new Rect();
rect.set(0, 0, wid, hgt);
//Measure the view at the exact dimensions (otherwise the text won't center correctly)
int widthSpec = View.MeasureSpec.makeMeasureSpec(rect.width(), View.MeasureSpec.EXACTLY);
int heightSpec = View.MeasureSpec.makeMeasureSpec(rect.height(), View.MeasureSpec.EXACTLY);
currView.measure(widthSpec, heightSpec);
//Lay the view out at the rect width and height
currView.layout(0, 0, rect.width(), rect.height());
//Translate the Canvas into position and draw it
canvas.save();
canvas.translate(rect.left, rect.top);
currView.draw(canvas);
canvas.restore();

Why not create the bitmap with porportions. To do so, you need to create a Scalable Bitmap, and make the width like 1/4 of the screen and the height one fourth of the screen height.
To do so, first in the onCreate() method, also add in the following code to get the screenWidth and Height. -
metrics = getResources().getDisplayMetrics();
display = getWindowManager().getDefaultDisplay();
dpi = metrics.densityDpi;
size = new Point();
display.getSize(size);
screenWidth = size.x;
screenHeight = size.y;
To create a scalable bitmap use the following code, but remember to set the width and height values porportional such as the following --
public static int height = MainActivity.screenWidth* 4/10;
public static int width = MainActivity.screenWidth* 4/10;
bg = BitmapFactory.decodeResource(getResources(), R.drawable.bg);
if (width + heigt > 0) {
bg = Bitmap.createScaledBitmap(bg,
(width), (heigt),
false);
}
Also, to make sure the drawable images stay in quality, make sure to create seperate drawable folders, such as 'xxhdpi,and hdpi.'Refer to http://developer.android.com/guide/practices/screens_support.html. Hope that helps. Good luck.

I created a new bitmap with the view and I merged it with the previous bitmap, the result was good:
Bitmap cameraBitmap = BitmapFactory.decodeByteArray
(data, 0, data.length);
int wid = cameraBitmap.getWidth();
int hgt = cameraBitmap.getHeight();
bitmap = Bitmap.createBitmap
(wid, hgt, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawBitmap(cameraBitmap, 0f, 0f, null);
ViewPager pager = (ViewPager) main_activity.findViewById(R.id.pager);
ScreenSlidePagerAdapter a = (ScreenSlidePagerAdapter) pager.getAdapter();
ScreenSlidePageFragment currFrag = (ScreenSlidePageFragment) a.instantiateItem(pager, a.getFocusedPage());
View currView = currFrag.getView();
Bitmap viewBitmap = CustomUtil.loadBitmapFromView(currView);
viewBitmap = Bitmap.createScaledBitmap(viewBitmap, wid, wid, false);
canvas.drawBitmap(viewBitmap, 0f, (hgt-wid)/2 /* to center my square view in my rectangular original bitmap */, null);
An utility method:
public static Bitmap loadBitmapFromView(View view) {
int width = view.getWidth();
int height = view.getHeight();
int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY);
//Cause the view to re-layout
view.measure(measuredWidth, measuredHeight);
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
//Create a bitmap backed Canvas to draw the view into
Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
//Now that the view is laid out and we have a canvas, ask the view to draw itself into the canvas
view.draw(c);
return b;
}

Create bitmap overlay with some information

I've created a Bitmap [Thumbnail] which is fetched after picking a video from gallery.
Snippet:-
bm= ThumbnailUtils.createVideoThumbnail(currentFileUri.getPath(), MediaStore.Video.Thumbnails.MICRO_KIND);
I'm putting these bitmap in Gallery adapter which is meant from images only, tht's y i'm creating thumbnail of Video and putting there. But
I want to show some difference between image and video in Gallery Strip which can be done by overlaying VideoThumbnail with something like Play Option.
Tried to OverLay my Bitmap with Small Play Icon but it throws NullPointerException on Bitmap.CreateScaledBitmap(..)
Snippet:-
bm= ThumbnailUtils.createVideoThumbnail(currentFileUri.getPath(), MediaStore.Video.Thumbnails.MICRO_KIND);
Bitmap change = null;
Bitmap border = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_media_play);
int width = bm.getWidth();
int height = bm.getHeight();
change = Bitmap.createScaledBitmap(change, width, height, false);
Canvas canvas = new Canvas(change);
Bitmap scaledBorder = Bitmap.createScaledBitmap(border,width/2,height/2, false);
canvas.drawBitmap(scaledBorder, 0, 0,null);
Adding that newly Overlay Created bitmap on my adapter.
AddIPDActivity.this.data.add(bm);

Created Overlay BitMap with LayerDrawable
Bitmap on which overlay need to be done.
bm = ThumbnailUtils.createVideoThumbnail(currentFileUri.getPath(),MediaStore.Video.Thumbnails.MICRO_KIND);
LayerDrawable applied on Bitmap with custom image on it.
Resources r = getResources();
Drawable[] layers = new Drawable[2];
layers[0] = new BitmapDrawable(bm);
layers[1] = r.getDrawable(android.R.drawable.ic_media_play);
LayerDrawable layerDrawable = new LayerDrawable(layers);
Added Bitmap on Gallery - Adapter.
this.data.add(drawableToBitmap(geSingleDrawable(layerDrawable))); //data is adapter for Gallery.
Converting LayerDrawable into BitMap:-
LayerDrawable -> Drawable -> BitMap
public static Drawable geSingleDrawable(LayerDrawable layerDrawable){
int resourceBitmapHeight = 136, resourceBitmapWidth = 153;
float widthInInches = 0.9f;
int widthInPixels = (int)(widthInInches * SmartConsultant.getApplication().getResources().getDisplayMetrics().densityDpi);
int heightInPixels = widthInPixels * resourceBitmapHeight / resourceBitmapWidth;
int insetLeft = 10, insetTop = 10, insetRight = 10, insetBottom = 10;
layerDrawable.setLayerInset(1, insetLeft, insetTop, insetRight, insetBottom);
Bitmap bitmap = Bitmap.createBitmap(widthInPixels, heightInPixels, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
layerDrawable.setBounds(0, 0, widthInPixels, heightInPixels);
layerDrawable.draw(canvas);
BitmapDrawable bitmapDrawable = new BitmapDrawable(SmartConsultant.getApplication().getResources(), bitmap);
bitmapDrawable.setBounds(0, 0, widthInPixels, heightInPixels);
return bitmapDrawable;
}
public static Bitmap drawableToBitmap (Drawable drawable) {
if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable)drawable).getBitmap();
}
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}

u r getting NPE because
Bitmap change = null;
change = Bitmap.createScaledBitmap(change, width, height, false);
change is always null. U r passing a null value.So, before passing change as a parameter of createScaledBitmap(parameters) assign a bitmap to change after that call this
change = Bitmap.createScaledBitmap(change, width, height, false);

merge two images (one image is transparent without face , second image is only face which coming from sdcard)

I have a two image one image is containing body without face and one image contain with face only...
now I want to merge this two images.... the first image which contain only body without face is in that the face is transparent.....
So how can I detect that transparent area and place face over there in transparent area?
I am combining two images with below code.. but it is not proper way to place face over transparent area
My code is given below,
public Bitmap combineImages(Bitmap c, Bitmap s) {
Bitmap cs = null;
int width, height = 0;
if (c.getWidth() > s.getWidth()) {
width = c.getWidth() + s.getWidth();
height = c.getHeight();
} else {
width = s.getWidth() + s.getWidth();
height = c.getHeight();
}
cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas comboImage = new Canvas(cs);
comboImage.drawBitmap(c, 0f, 0f, null);
comboImage.drawBitmap(s, 0f, 0f, null);
return cs;
}

Merge two or more images in android by using Canvas its simple to merge image by using below code,
first create bitmap for particular image which you want to merge it.
get X and Y axis position for which area you want to merge images.
mComboImage = new Canvas(mBackground);
mComboImage.drawBitmap(c, x-axis position in f, y-axis position in f, null);
mComboImage.drawBitmap(c, 0f, 0f, null);
mComboImage.drawBitmap(s, 200f, 200f, null);
mBitmapDrawable = new BitmapDrawable(mBackground);
Bitmap mNewSaving = ((BitmapDrawable)mBitmapDrawable).getBitmap();
set this new bitmap in imageview.
imageView.setImageBitmap(mNewSaving);
Here in this method two image bitmap combine in one bitmap which return bitmap of new merge image.Also save this image on sdcard.As below code
public Bitmap combineImages(Bitmap c, Bitmap s) {
Bitmap cs = null;
int width, height = 0;
if(c.getWidth() > s.getWidth()) {
width = c.getWidth();
height = c.getHeight() + s.getHeight();
} else {
width = s.getWidth();
height = c.getHeight() + s.getHeight();
}
cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas comboImage = new Canvas(cs);
comboImage.drawBitmap(c, new Matrix(), null);
comboImage.drawBitmap(s, new Matrix(), null);
// this is an extra bit I added, just incase you want to save the new image somewhere and then return the location.
return cs;
}
}

Here is the proper way to merge two bitmaps:
public Bitmap combineImages(Bitmap topImage, Bitmap bottomImage) {
Bitmap overlay = Bitmap.createBitmap(bottomImage.getWidth(), bottomImage.getHeight(), bottomImage.getConfig());
Canvas canvas = new Canvas(overlay);
canvas.drawBitmap(bottomImage, new Matrix(), null);
canvas.drawBitmap(topImage, 0, 0, null);
return overlay;
}

Overlay Bitmap over another Android

hello guys i'm trying to get an image(Frame from resources) to overlay it over the original bitmap. so far i couldn't make my Bitmap goes into the frame as the frame always empty. the original bitmap is now showing inside the frame.
here is my code that i'm using to accomplish this.
Canvas canvas = new Canvas();
Bitmap border = null;
Bitmap scaledBorder = null;
border = BitmapFactory.decodeResource(getResources(), R.drawable.frame1);
int width = bmp.getWidth();
int height = bmp.getHeight();
scaledBorder = Bitmap.createScaledBitmap(border,width,height, false);
canvas.drawBitmap(scaledBorder, 0, 0, new Paint());
view.setImageBitmap(scaledBorder);
bmp as my original Bitmap from Gallery or Camera. i can't find away to put them together. only the frame will appear but not the bmp.
thanks in advance.

thanks man i figured it out by own. using this
void hm1(){
Bitmap border = BitmapFactory.decodeResource(getResources(), R.drawable.vignette2);
int width = bmp.getWidth();
int height = bmp.getHeight();
change = Bitmap.createScaledBitmap(change, width, height, false);
Canvas canvas = new Canvas(change);
Bitmap scaledBorder = Bitmap.createScaledBitmap(border,width,height, false);
canvas.drawBitmap(scaledBorder, 0, 0,null);
//canvas.drawBitmap(k, 0, 0, null);
view.setImageBitmap(change);
}
by adding this method on any click button , menu etc you can draw two bitmaps over each other.
P.S : Bitmap change is another bitmap from the original one as i don't want the user to apply the Overlay on the original method but on the changed one.
hope the answer helps someone. thanks

Bottom line, first you need to add your original image to the canvas, then the border, then place the canvas on the view. Your best bet is to do this in an onDraw() method. Something like this should work:
#Override
void onDraw (Canvas canvas)
{
canvas.drawBitmap(bmp,0,0,new Paint())
Bitmap border = null;
Bitmap scaledBorder = null;
border = BitmapFactory.decodeResource(getResources(), R.drawable.frame1);
int width = bmp.getWidth();
int height = bmp.getHeight();
scaledBorder = Bitmap.createScaledBitmap(border,width,height, false);
canvas.drawBitmap(scaledBorder, 0, 0, new Paint());
}
Alternatively, you could call the draw() function from the view.
canvas.drawBitmap(bmp,0,0,new Paint())
Bitmap border = null;
Bitmap scaledBorder = null;
border = BitmapFactory.decodeResource(getResources(), R.drawable.frame1);
int width = bmp.getWidth();
int height = bmp.getHeight();
scaledBorder = Bitmap.createScaledBitmap(border,width,height, false);
canvas.drawBitmap(scaledBorder, 0, 0, new Paint());
view.draw(canvas);

Converting a view to Bitmap without displaying it in Android?

I will try to explain what exactly I need to do.
I have 3 separate screens say A,B,C. There is another screen called say HomeScreen where all the 3 screens bitmap should be displayed in Gallery view and the user can select in which view does he wants to go.
I have been able to get the Bitmaps of all the 3 screens and display it in Gallery view by placing all the code in HomeScreen Activity only. Now, this has complicated the code a lot and I will like to simplify it.
So, can I call another Activity from HomeScreen and do not display it and just get the Bitmap of that screen. For example, say I just call HomeScreen and it calls Activity A,B,C and none of the Activities from A,B,C are displayed. It just gives the Bitmap of that screen by getDrawingCache(). And then we can display those bitmaps in Gallery view in HomeScreen.
I hope I have explained the problem very clearly.
Please let me know if this is actually possible.

there is a way to do this. you have to create a Bitmap and a Canvas and call view.draw(canvas);
here is the code:
public static Bitmap loadBitmapFromView(View v) {
Bitmap b = Bitmap.createBitmap( v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.layout(v.getLeft(), v.getTop(), v.getRight(), v.getBottom());
v.draw(c);
return b;
}
if the view wasn't displayed before the size of it will be zero. Its possible to measure it like this:
if (v.getMeasuredHeight() <= 0) {
v.measure(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Bitmap b = Bitmap.createBitmap(v.getMeasuredWidth(), v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
v.draw(c);
return b;
}
EDIT: according to this post, Passing WRAP_CONTENT as value to makeMeasureSpec() doesn't to do any good (although for some view classes it does work), and the recommended method is:
// Either this
int specWidth = MeasureSpec.makeMeasureSpec(parentWidth, MeasureSpec.AT_MOST);
// Or this
int specWidth = MeasureSpec.makeMeasureSpec(0 /* any */, MeasureSpec.UNSPECIFIED);
view.measure(specWidth, specWidth);
int questionWidth = view.getMeasuredWidth();

here is my solution:
public static Bitmap getBitmapFromView(View view) {
Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
Drawable bgDrawable =view.getBackground();
if (bgDrawable!=null)
bgDrawable.draw(canvas);
else
canvas.drawColor(Color.WHITE);
view.draw(canvas);
return returnedBitmap;
}
Enjoy :)

I know this may be a stale issue, but I was having problems getting any of these solutions to work for me.
Specifically, I found that if any changes were made to the view after it was inflated that those changes would not get incorporated into the rendered bitmap.
Here's the method which ended up working for my case. With one caveat, however. prior to calling getViewBitmap(View) I inflated my view and asked it to layout with known dimensions. This was needed since my view layout would make it zero height/width until content was placed inside.
View view = LayoutInflater.from(context).inflate(layoutID, null);
//Do some stuff to the view, like add an ImageView, etc.
view.layout(0, 0, width, height);
Bitmap getViewBitmap(View view)
{
//Get the dimensions of the view so we can re-layout the view at its current size
//and create a bitmap of the same size
int width = view.getWidth();
int height = view.getHeight();
int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY);
//Cause the view to re-layout
view.measure(measuredWidth, measuredHeight);
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
//Create a bitmap backed Canvas to draw the view into
Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
//Now that the view is laid out and we have a canvas, ask the view to draw itself into the canvas
view.draw(c);
return b;
}
The "magic sauce" for me was found here:

Try this,
/**
* Draw the view into a bitmap.
*/
public static Bitmap getViewBitmap(View v) {
v.clearFocus();
v.setPressed(false);
boolean willNotCache = v.willNotCacheDrawing();
v.setWillNotCacheDrawing(false);
// Reset the drawing cache background color to fully transparent
// for the duration of this operation
int color = v.getDrawingCacheBackgroundColor();
v.setDrawingCacheBackgroundColor(0);
if (color != 0) {
v.destroyDrawingCache();
}
v.buildDrawingCache();
Bitmap cacheBitmap = v.getDrawingCache();
if (cacheBitmap == null) {
Log.e(TAG, "failed getViewBitmap(" + v + ")", new RuntimeException());
return null;
}
Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);
// Restore the view
v.destroyDrawingCache();
v.setWillNotCacheDrawing(willNotCache);
v.setDrawingCacheBackgroundColor(color);
return bitmap;
}

There is a great Kotlin extension function in Android KTX: View.drawToBitmap(Bitmap.Config)

Layout or view to bitmap:
private Bitmap createBitmapFromLayout(View tv) {
int spec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
tv.measure(spec, spec);
tv.layout(0, 0, tv.getMeasuredWidth(), tv.getMeasuredHeight());
Bitmap b = Bitmap.createBitmap(tv.getMeasuredWidth(), tv.getMeasuredWidth(),
Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
c.translate((-tv.getScrollX()), (-tv.getScrollY()));
tv.draw(c);
return b;
}
Calling Method:
Bitmap src = createBitmapFromLayout(View.inflate(this, R.layout.sample, null)/* or pass your view object*/);

I think this is a bit better :
/**
* draws the view's content to a bitmap. code initially based on :
* http://nadavfima.com/android-snippet-inflate-a-layout-draw-to-a-bitmap/
*/
#Nullable
public static Bitmap drawToBitmap(final View viewToDrawFrom, int width, int height) {
boolean wasDrawingCacheEnabled = viewToDrawFrom.isDrawingCacheEnabled();
if (!wasDrawingCacheEnabled)
viewToDrawFrom.setDrawingCacheEnabled(true);
if (width <= 0 || height <= 0) {
if (viewToDrawFrom.getWidth() <= 0 || viewToDrawFrom.getHeight() <= 0) {
viewToDrawFrom.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
width = viewToDrawFrom.getMeasuredWidth();
height = viewToDrawFrom.getMeasuredHeight();
}
if (width <= 0 || height <= 0) {
final Bitmap bmp = viewToDrawFrom.getDrawingCache();
final Bitmap result = bmp == null ? null : Bitmap.createBitmap(bmp);
if (!wasDrawingCacheEnabled)
viewToDrawFrom.setDrawingCacheEnabled(false);
return result;
}
viewToDrawFrom.layout(0, 0, width, height);
} else {
viewToDrawFrom.measure(MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY));
viewToDrawFrom.layout(0, 0, viewToDrawFrom.getMeasuredWidth(), viewToDrawFrom.getMeasuredHeight());
}
final Bitmap drawingCache = viewToDrawFrom.getDrawingCache();
final Bitmap bmp = ThumbnailUtils.extractThumbnail(drawingCache, width, height);
final Bitmap result = bmp == null || bmp != drawingCache ? bmp : Bitmap.createBitmap(bmp);
if (!wasDrawingCacheEnabled)
viewToDrawFrom.setDrawingCacheEnabled(false);
return result;
}
Using the above code, you don't have to specify the size of the bitmap (use 0 for width&height) if you want to use the one of the view itself.
Also, if you wish to convert special views (SurfaceView, Surface or Window, for example) to a bitmap, you should consider using PixelCopy class instead. It requires API 24 and above though. I don't know how to do it before.

Hope this helps
View view="some view instance";
view.setDrawingCacheEnabled(true);
Bitmap bitmap=view.getDrawingCache();
view.setDrawingCacheEnabled(false);
Update
getDrawingCache() method is deprecated in API level 28. So look for other alternative for API level > 28.

I used this just a few days ago:
fun generateBitmapFromView(view: View): Bitmap {
val specWidth = View.MeasureSpec.makeMeasureSpec(1324, View.MeasureSpec.AT_MOST)
val specHeight = View.MeasureSpec.makeMeasureSpec(521, View.MeasureSpec.AT_MOST)
view.measure(specWidth, specHeight)
val width = view.measuredWidth
val height = view.measuredHeight
val bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
view.layout(view.left, view.top, view.right, view.bottom)
view.draw(canvas)
return bitmap
}
This code is based in this gist

I had a similar need and developed something based on codes provided, specially the one by #Azhagthott and the brand new androidx.core.view.drawToBitmap, hopefully this will be hopeful here also,
val view = MyCustomView(context)
view.measure(
View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.AT_MOST),
View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.AT_MOST)
)
view.layout(0, 0, width, height)
val bitmap = view.drawToBitmap()

private fun getBitmapFromView(view: View): Bitmap
{
val returnedBitmap = Bitmap.createBitmap(view.width,
view.height
,Bitmap.Config.ARGB_8888)
val canvas = Canvas(returnedBitmap)
//background image
val bgDrawable = view.background
//background image is selected
if (bgDrawable != null){
bgDrawable.draw(canvas)
}
else{
canvas.drawColor(Color.WHITE)
}
view.draw(canvas)
return returnedBitmap
}

I had the same problem in my project and found a solution, which I will describe here.
public Bitmap catchBitmapFromView(View capture_view){
if (capture_view == null) {
return null;
}
capture_view.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(capture_view.getWidth(), capture_view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
Drawable bgDrawable = capture_view.getBackground();
if (bgDrawable != null) {
bgDrawable.draw(canvas);
} else {
canvas.drawColor(Color.WHITE);
}
capture_view.draw(canvas);
capture_view.setDrawingCacheEnabled(false);
return bitmap;
}

view.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
view.setDrawingCacheEnabled(false);
