How to set an ImageView into a fragment Android?

My app needs a profile's image either taking a photo or choose from gallery. I'm on a fragment and when I click a button I can choose if take a photo or choose it from gallery. The function works and I open the camera and the gallery, but when I return on my fragment I don't see the image taking or choosing into my ImageView why?
I use this code:
AlertDialog to choose the option:
final CharSequence[] items = { "Take Photo", "Choose from Library", "Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Add Photo");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (items[item].equals("Take Photo")) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, REQUEST_CAMERA);
} else if (items[item].equals("Choose from Library")) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
Taking photo:
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
Toast.makeText(getActivity().getApplicationContext(),"OK" , Toast.LENGTH_LONG).show();
etImage.setImageBitmap(thumbnail);
Choose from gallery:
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
etImage.setImageURI(selectedImageUri);
The whole onActivityResult() is
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == getActivity().RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
Toast.makeText(getActivity().getApplicationContext(),"OK" , Toast.LENGTH_LONG).show();
etImage.setImageBitmap(thumbnail);
} else if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
etImage.setImageURI(selectedImageUri);
}
}
So what is the problem? Logcat doesn't show me any errors

Trying to display image taken from camera intent

I'm Currently trying to take a photo from the default camera intent from the MainActivity and then put that image in an ImageView in the same activity.
I'm saving the images such that the image taken overwrites the previously taken image (In this case, I call the image test.jpg and I store it in sdcard)
The problem I have with my code right now is the ImageView displays the photo taken the previous time the application ran.
Here is my code.
public class MainActivity extends Activity
{
ImageView imv;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imv = (ImageView)findViewById(R.id.imv);
Uri uri = null;
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/test.jpg";
try
{
uri = takePhoto(path);
}
catch(Exception e)
{
e.printStackTrace();
}
imv.setImageURI(uri);
}
private Uri takePhoto(String path) throws IOException
{
File photo = new File(path);
photo.createNewFile();
Uri fileUri = Uri.fromFile(photo);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(cameraIntent, 0);
fileUri = Uri.fromFile(new File(path));
return fileUri;
}
}

Try to set image in onActivityResult as below:
protected void onActivityResult(int requestCode, int resultCode, Intent ata)
{
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
imv = (ImageView)findViewById(R.id.imv);
Bitmap photo = (Bitmap) data.getExtras().get("data");
imv.setImageBitmap(photo);
}}}

private static final int PICK_CONTACT_REQUEST = 0 ;
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == PICK_CONTACT_REQUEST) {
if (resultCode == RESULT_OK) {
imv.setImageURI(uri);
}
}
}
Set the image in onactivity result it will show new Image taken from the camera .

Try this,
private Uri takePhoto(String path) throws IOException
{
File photo = new File(path);
photo.createNewFile();
if(photo.exists())
photo.delete();
photo = new File(path);
Uri fileUri = Uri.fromFile(photo);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(cameraIntent, 0);
fileUri = Uri.fromFile(new File(path));
return fileUri;
}

Using the camera intent to take a picture without an sdcard

I'm having trouble using the camera when there's no sdcard present.
When there is an sdcard, using the camera is trivial, e.g.
http://www.vogella.com/articles/AndroidCamera/article.html + a plethora of other examples.
However, I need to make my app available to devices which don't have SD cards, (e.g. the Sony Xperia series.) I've tried modifying the code such that I'm using the internal storage (I think):
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(getDir("myDirec", Context.MODE_WORLD_WRITEABLE), "tmp_photo_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
file.createNewFile();
mImageCaptureUri = Uri.fromFile(file);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
intent.putExtra("return-data", true);
However, upon result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intentReturn) {
if (resultCode != RESULT_OK)
return;
String path = mImageCaptureUri.getPath();
Bitmap bitmap = BitmapFactory.decodeFile(path);
...
bitmap is null.
Which leads me to believe that there's some permissions issue....maybe?
I've tried some of the other internal storage options, http://developer.android.com/guide/topics/data/data-storage.html#filesInternal e.g. getFilesDir() but the same result: null bitmap.
Has anyone had any success in using the camera without an sdcard?

Try this. It works..
private Uri imageUri;
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.btnImageCapture:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File dir = context.getDir("directory", Context.MODE_PRIVATE);
File photo = new File(dir, "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, OPEN_CAMERA);
break;
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case OPEN_CAMERA:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
}
}
}
}

Android - Cropping after Camera and Gallery Intents Gives Strange Results

I'm trying to launch an Android camera intent and a choose-photo intent (two buttons, one for take photo, one for choose from gallery) and both need a crop intent launched after them then have the cropped photo returned to my app's activity. I've gone through a bunch of the examples posted elsewhere, but I'm getting strange reults with my implementation.
For the take photo event, it appears to work fine, except after taking a photo and going into crop mode, the wrong photo pops up. Instead of cropping the photo you just took it crops an older photo and I can't figure out where it's coming from. Also, sometimes after finishing the crop intent, it crashes with a nullpointerexception after Parcel.readException (can't always reproduce, but I think it haappens more if you take a picture and crop as quickly as possible).
For the choose photo intent, your gallery pops up as expected but upon choosing a photo all that happens is the message "Saved" is toasted instead of returning to my app's activity with the image. I believe I have a misunderstanding of how the choose photo intent works (I pretty much reused the code for the take photo intent).
In both cases, in crop mode you are still allowed to resize the cropped area despite having specified "scale" = false.
My code is as follows:
public class TestPhotoActivity extends Activity {
private ImageView imageView;
private Uri imageUri;
private int int_Height_crop = 600;
private int int_Width_crop = 600;
public final static int TAKE_PICTURE = 0;
public final static int CHOOSE_PICTURE = 1;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.choose_photo);
imageView = (ImageView) findViewById(R.id.photo);
Button take_photo = (Button) findViewById(R.id.take_photo);
take_photo.setOnClickListener(new View.OnClickListener() {
public void onClick(final View view) {
takePhoto(view);
}
});
Button choose_photo = (Button) findViewById(R.id.choose_photo);
choose_photo.setOnClickListener(new View.OnClickListener() {
public void onClick(final View view) {
choosePhoto(view);
}
});
}
public void takePhoto(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE", null);
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", int_Width_crop);
intent.putExtra("outputY", int_Height_crop);
intent.putExtra("scale", false);
intent.putExtra("return-data", true);
File photo = new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis() + ".jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true);
startActivityForResult(intent, TAKE_PICTURE);
}
public void choosePhoto(View view) {
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", int_Width_crop);
intent.putExtra("outputY", int_Height_crop);
intent.putExtra("scale", false);
intent.putExtra("return-data", true);
File photo = new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis() + "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(intent, CHOOSE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
Log.d("photo", "requestCode: " + requestCode + "resultCode: " + resultCode + "wanted result: " + Activity.RESULT_OK);
if (resultCode == Activity.RESULT_OK) {
if (data == null) {
Log.w("photo", "Null data, but RESULT_OK, from image picker!");
Toast t = Toast.makeText(this, "No photo picked.", Toast.LENGTH_SHORT);
t.show();
return;
}
final Bundle extras = data.getExtras();
if (extras != null) {
Log.d("photo", "extras is not null");
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, selectedImage);
Log.d("photo", "data.getAction() is not null. setting image.");
imageView.setImageBitmap(bitmap);
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
Log.e("photo", e.toString());
}
}
}
case CHOOSE_PICTURE:
Log.d("photo", "requestCode: " + requestCode + "resultCode: " + resultCode + "wanted result: " + Activity.RESULT_OK);
if(resultCode == RESULT_OK){
Log.d("photo", "resultCode is ok");
if (data == null) {
Log.w("photo", "Null data, but RESULT_OK, from image picker!");
Toast t = Toast.makeText(this, "No photo picked.", Toast.LENGTH_SHORT);
t.show();
return;
}
final Bundle extras = data.getExtras();
if (extras != null) {
Log.d("photo", "extras is not null");
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, selectedImage);
Log.d("photo", "data.getAction() is not null. setting image.");
imageView.setImageBitmap(bitmap);
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
Log.e("photo", e.toString());
}
}
}
}
}
}
Any help is greatly appreciated!
EDIT: I should also note that I'm testing on an LG Optimus LTE, Android 2.3

I think your problem comes from useing System.currentTimeMillis() in the temp file name. This would explain sometimes getting an older file.
I would suggest just reusing the same temp file.
Hope it helps...

capturing image using camera in Android

Hi stackoverflow friends,
I need to take a picture using camera and after takin the picture go to next activity without showing the first activity. And display it in an imageview.
Below is the flow of my application
first activity-> there is button for camera intent->go to the next activity(without showing the fist activity) second activity->there i need to show the image in imageview.
I saw a lot of examples of camera intent nobody explains how to go to the next activity without showing the first and display it in imageview of second.
Any outofmemeory problem occurs while displaying images in imageview repeatedly?
Thanks in advance

In First activity :
Button b=(Button)findViewByid(R.id.button);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
doTakePhotoAction();
}
});
private void doTakePhotoAction() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"pic_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, CAMERA_RESULT);
// finish();
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == CAMERA_RESULT) {
Intent intent = new Intent(this, nextimage.class);
// here you have to pass absolute path to your file
intent.putExtra("image-path", mUri.getPath());
intent.putExtra("scale", true);
startActivity(intent);
finish();
}
}
In nextimage.class you can set one image view and get the imagepath from putExtra and place it in imageview.
String mImagePath = extras.getString("image-path");
Bitmap mBitmap = getBitmap(mImagePath);
private Uri getImageUri(String path) {
return Uri.fromFile(new File(path));
}
private Bitmap getBitmap(String path) {
Uri uri = getImageUri(path);
InputStream in = null;
try {
in = mContentResolver.openInputStream(uri);
return BitmapFactory.decodeStream(in);
} catch (FileNotFoundException e) {
Log.e(TAG, "file " + path + " not found");
}
return null;
}
place the bitmap in the imageview.you have to create imageview in secondActivity.

use a camera intent....here's a simple code
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.widget.ImageView;
public class CameraIntent extends Activity {
final static int CAMERA_RESULT = 0;
ImageView imv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_RESULT);
}
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK)
{
Get Bundle extras = intent.getExtras();
Bitmap bmp = (Bitmap) extras.get("data");
imv = (ImageView) findViewById(R.id.ReturnedImageView);
imv.setImageBitmap(bmp);
}
}
}

Use Following Code for that, it will solve your problem.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
onActivityResult() Method:-
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_PIC_REQUEST) {
bmpImage = (Bitmap) data.getExtras().get("data");
drawable = new BitmapDrawable(bmpImage);
mImageview.setImageDrawable(drawable);
}
}
}
