Assuming you are calling this in an Activity class Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image); The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).
Try something like this: Bitmap bmp = intent.getExtras().get(“data”); ByteArrayOutputStream stream = new ByteArrayOutputStream(); bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); byte[] byteArray = stream.toByteArray(); bmp.recycle();
Change: profileImage.setImageBitmap( BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length) To: Bitmap b = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length) profileImage.setImageBitmap(Bitmap.createScaledBitmap(b, 120, 120, false));
Try this it converts a Bitmap type image to Drawable Drawable d = new BitmapDrawable(getResources(), bitmap);
try (FileOutputStream out = new FileOutputStream(filename)) { bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance // PNG is a lossless format, the compression factor (100) is ignored } catch (IOException e) { e.printStackTrace(); }
From Android developer: // show The Image in a ImageView new DownloadImageTask((ImageView) findViewById(R.id.imageView1)) .execute(“http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png”); public void onClick(View v) { startActivity(new Intent(this, IndexActivity.class)); finish(); } private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> { ImageView bmImage; public DownloadImageTask(ImageView bmImage) { this.bmImage = bmImage; } protected Bitmap doInBackground(String… urls) { String urldisplay = urls[0]; Bitmap mIcon11 = null; … Read more
This piece of code helps. Bitmap icon = BitmapFactory.decodeResource(context.getResources(), R.drawable.icon_resource); Here a version where the image gets downloaded. String name = c.getString(str_url); URL url_value = new URL(name); ImageView profile = (ImageView)v.findViewById(R.id.vdo_icon); if (profile != null) { Bitmap mIcon1 = BitmapFactory.decodeStream(url_value.openConnection().getInputStream()); profile.setImageBitmap(mIcon1); }
To fix the OutOfMemory error, you should do something like this: BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 8; Bitmap preview_bitmap = BitmapFactory.decodeStream(is, null, options); This inSampleSize option reduces memory consumption. Here’s a complete method. First it reads image size without decoding the content itself. Then it finds the best inSampleSize value, it should be … Read more
