Get Image from camera into ImageView Android
12,405
To get a full size picture you need to first save it to file and then extract it's bitmap from it, do this:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, CAPTURE_NEW_PICTURE);
Then in onActivityResult
:
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
mImage = (ImageView) findViewById(R.id.imageView1);
mImage.setImageBitmap(decodeSampledBitmapFromFile(file.getAbsolutePath(), 500, 250));
When decodeSampledBitmapFromFile
:
public static Bitmap decodeSampledBitmapFromFile(String path,
int reqWidth, int reqHeight) { // BEST QUALITY MATCH
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
// Calculate inSampleSize
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
options.inPreferredConfig = Bitmap.Config.RGB_565;
int inSampleSize = 1;
if (height > reqHeight) {
inSampleSize = Math.round((float)height / (float)reqHeight);
}
int expectedWidth = width / inSampleSize;
if (expectedWidth > reqWidth) {
//if(Math.round((float)width / (float)reqWidth) > inSampleSize) // If bigger SampSize..
inSampleSize = Math.round((float)width / (float)reqWidth);
}
options.inSampleSize = inSampleSize;
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(path, options);
}
You can play with the numbers (500 and 250 in this case) to change the quality of the bitmap for the ImageView

The following code works well to get the thumbnail of a picture taken from the camera. I want to get the full image, not just the thumbnail. I have a Samsung Galaxy Nexus
private static final int CAMERA_PIC_REQUEST = 1111; private ImageView mImage; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_my_camera); mImage = (ImageView) findViewById(R.id.imageView1); Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intent, CAMERA_PIC_REQUEST); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_PIC_REQUEST) { Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); mImage.setImageBitmap(thumbnail); ByteArrayOutputStream bytes = new ByteArrayOutputStream(); thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, bytes); File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg"); try { file.createNewFile(); FileOutputStream fo = new FileOutputStream(file); fo.write(bytes.toByteArray()); fo.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
