Adding images from assets folder in adapter

I'm trying to display images from assets folder. I have this error:
Bitmap bitmap = getBitmapFormatAssets(product.getProductId());
try { Bitmap bitmap = getBitmap(product.getProductId()); imageView.setImageResource(bitmap);

It must be setImageBitmap(bitmap) not setImageResource(bitmap)

Instead of imageView.setImageResource(bitmap) try to use imageView.setImageBitmap(bitmap) directly.

when you want to set a bitmap image to a image view don't use setImageResource(bitmap)
use setImageBitmap(bitmap) as below
setImageBitmap(bitmap) Sets a Bitmap as the content of this ImageView.
like this
imageView.setImageBitmap(bitmap)
get your bitmap from assets using below code
private Bitmap getBitmapFromAsset(String strName)
{
AssetManager assetManager = getAssets();
InputStream istr = null;
try {
istr = assetManager.open(strName);
} catch (IOException e) {
e.printStackTrace();
}
Bitmap bitmap = BitmapFactory.decodeStream(istr);
return bitmap;
}

following are used for getting the image from asset folder and set it to ImageView.
// load image
try {
// get input stream
InputStream ims = getAssets().open("avatar.jpg");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
mImage.setImageDrawable(d);
}
catch(IOException ex) {
return;
}

Load Images from Assets in Widget remoteView

I am using the following code to load my image into Android widget ImageView:
remoteViews.setImageViewResource(R.id.widget_image, R.drawable.image);
I have to save the image in drawable folder. Is it possible to save the image in assets instead and load it to remoteView?

Using BitmapFactory, you can load an image in assets/ as a Bitmap from an InputStream provided by AssetManager, and then use the RemoteViews#setImageViewBitmap() method to set it on your widget.
For example:
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
...
try {
InputStream is = context.getAssets().open("image.jpg");
Bitmap bmp = BitmapFactory.decodeStream(is);
remoteViews.setImageViewBitmap(R.id.widget_image, bmp);
}
catch (IOException e) {
e.printStackTrace();
}

Here is the solution :
imageView = (ImageView)findViewById(R.id.iv);
try {
// get input stream
InputStream ims = getAssets().open("download.jpg");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
imageView.setImageDrawable(d);
}
catch(IOException ex) {
return;
}

Getting Image from drawable and adding to PDF using iText

I want to add image to android PDF using iText. I want to achieve this without saving image to SDCard first. I put my image into res/drawable folder but proving the image path doesn’t work and it throws FileNotFound Exception. My path is like this:
String path = “res/drawable/myImage.png”
Image image = Image.getInstance(path);
document.add(image);
Now please suggest me a solution how I will add correct file path to getInstance(…) method. Thanks

Of course it'll not work at that way.
move your image to assets folder to access it with getassets() method
// load image
try {
// get input stream
InputStream ims = getAssets().open("myImage.png");
Bitmap bmp = BitmapFactory.decodeStream(ims);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
Image image = Image.getInstance(stream.toByteArray());
document.add(image);
}
catch(IOException ex)
{
return;
}

I found a solution for your issue. If you want to get image from your drawable folder and put it into a PDF file using iText use this code:
try {
document.open();
Drawable d = getResources().getDrawable(R.drawable.myImage);
BitmapDrawable bitDw = ((BitmapDrawable) d);
Bitmap bmp = bitDw.getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
Image image = Image.getInstance(stream.toByteArray());
document.add(image);
document.close();
} catch (Exception e) {
e.printStackTrace();
}

Here is the code to add image to PDF using iText, if the image is dynamic (i.e), if the image cannot be added to asset folder at compile time,
public void addImage(Document document,ImageView ivPhoto) throws DocumentException {
try {
BitmapDrawable drawable = (BitmapDrawable) ivPhoto.getDrawable();
Bitmap bitmap = drawable.getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] imageInByte = stream.toByteArray();
Image image = Image.getInstance(imageInByte);
document.add(image);
}
catch(IOException ex)
{
return;
}
}

Here is my code, To set Image on particular position
move your image to assets folder to get image by getassets() method.
Hope this will help you!
try {
InputStream ims = getAssets().open("header1.png");
Bitmap bmp = BitmapFactory.decodeStream(ims);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
Image image = Image.getInstance(stream.toByteArray());
image.setAbsolutePosition(10f,750f);
image.scaleToFit(850,78);
document.add(image);
}
catch(IOException ex)
{
ex.printStackTrace();
return;
}

try {
FileInputStream in = new FileInputStream("input file uri");
PdfReader pdfReader = new PdfReader(in);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileOutputStream("output file uri"));
PdfContentByte content = pdfStamper.getOverContent(1);
Image deliverImg = Image.getInstance("image URI");
deliverImg.setAbsolutePosition(420f, 100f);
content.addImage(deliverImg);
pdfStamper.close();
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
}

Android : cannot read image in assets folder and assign to imageview

I have a file food.jpg in assets folder. I have try many ways. but I still cannot get this image into imageView. when run, instead of display image "food.jpg", it displays image that I have declared in xml file. (that image is in drawable folder).
The first way is:
int asset_id = context.getResources().getIdentifier("food", "drawable", context.getPackageName());
imageView.setImageResource(asset_id);
The second way is:
AssetManager assetManager = context.getAssets();
InputStream istr;
try {
istr = assetManager.open("food");
Bitmap bitmap = BitmapFactory.decodeStream(istr);
imageView.setImageBitmap(bitmap);
istr.close();
} catch (IOException e) {
e.printStackTrace();
}
Please teach me how to fix this problem.
thanks :)

Your code is working fine. just add image MIME-Type(.jpg,jpeg,.png... etc) in below line:
istr = assetManager.open("ceo.jpg");
full code for your refrance
AssetManager assetManager = getAssets();
InputStream istr;
try {
istr = assetManager.open("ceo.jpg");
Bitmap bitmap = BitmapFactory.decodeStream(istr);
imageView.setImageBitmap(bitmap);
istr.close();
} catch (IOException e) {
e.printStackTrace();
}

Try this Code...
try {
// get input stream
InputStream ims = getAssets().open("food.jpg");
// load image as Drawable
Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
imgNews.setImageDrawable(d);
} catch (Exception ex) {
return;
}
}

How to display the image from assets folder in android?

I have kept my images in assets folder and tried to display them. I tried in many ways but still I am unable to display the image. In logcat it is not displaying any error.
Please help me regarding this..........
AssetManager mngr = mContext.getResources().getAssets();
is = mngr.open("test3.png");
bitmap = BitmapFactory.decodeStream(is);
Uri uriSavedImage=Uri.fromFile(pictures_directory);
((ImageView) view.findViewById(R.id.imageView1)).setImageBitmap(bitmap);

You can use AssetManager to get the InputStream using its open() method and then use decodeStream() method of BitmapFactory to get the Bitmap.
private Bitmap getBitmapFromAsset(String strName)
{
AssetManager assetManager = getAssets();
InputStream istr = null;
try {
istr = assetManager.open(strName);
} catch (IOException e) {
e.printStackTrace();
}
Bitmap bitmap = BitmapFactory.decodeStream(istr);
return bitmap;
}

Something isn't right here, what error are you getting? Because the error in you question wouldn't come up from that code below... if anything it would say "Unable to open content: file:///testing/test3.png."
It sound like your images are stored in the wrong place and that is why it's saying it can't find them.
