Android - Image Picker, Wrong Image - android

I am starting a request for an image pick:
Intent intent = new Intent();
intent.setType( "image/*" );
intent.setAction( Intent.ACTION_GET_CONTENT );
startActivityForResult( Intent.createChooser( intent, "Choose"), PHOTO_GALLERY );
And getting the data back out in onActivityResult:
if( resultCode == Activity.RESULT_OK && requestCode == PHOTO_GALLERY )
{
U.log( data.getData() );
Bitmap bm = ... // built from the getData() Uri
this.postImagePreview.setImageBitmap( bm );
}
When I launch the Intent, I see some folders, such as sdcard, Drop Box, MyCameraApp, and so on.
If I chose a picture from sdcard, when I load the preview, it is the completely wrong image. The other folders don't seem to be giving me this problem.
Does anyone know why it'd let me pick one image, then give me the Uri for another?
EDIT: Here are some exampled logged getData()s:
Good:
content://com.google.android.gallery3d.provider/picasa/item/5668377679792530210
Bad:
content://media/external/images/media/28
EDIT: I'm still having issues, when picking from the sdcard folder of gallery.
Here is a bit more expansion of what I'm doing in onActivityResult:
// cursor
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = mContext.getContentResolver().query( selectedImage, filePathColumn, null, null, null );
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex( filePathColumn[0] );
String filePath = cursor.getString( columnIndex );
cursor.close();
// Cursor: /mnt/sdcard/Pic.jpg : /mnt/sdcard/Pic.jpg
U.log( "Cursor: " + filePath + " : " + Uri.parse( filePath ) );
// "regular"
// Regular: content://media/external/images/media/28 : content://media/external/images/media/28
U.log( "Regular: " + data.getDataString() + " : " + Uri.parse( data.getDataString() ) );
// Regular 2: content://media/external/images/media/28 : content://media/external/images/media/28
U.log( "Regular 2: " + data.getData() + " : " + data.getData() );
mPostImagePreview.setImageBitmap( BitmapFactory.decodeFile( filePath ) );
mPostImagePreview.setVisibility( View.VISIBLE );
They still set the wrong image. If I go into the Gallery, long press the image, and view its details I get:
TItle: Pic
Time: May 2, 2012
Width: 720
Height: 1280
Orientation: 0
File size: 757KB
Maker: Abso Camera
Model: Inspire 4G
Path: /mnt/sdcard/Pic.jpg
So, the Gallery is telling me the path is the same as the pick action, and the Gallery is rendering it correctly. So why on earth is it not rendering if I set it from onActivityResult?
Also, this is the code I'm using to fire the Intent now:
private void selectPhoto()
{
Intent intent = new Intent( Intent.ACTION_GET_CONTENT );
intent.setType( "image/*" );
( ( Activity )mContext ).startActivityForResult( Intent.createChooser( intent, "Select Picture" ), PHOTO_GALLERY );
}

Sometimes the thumbnails in the gallery app can be outdated and show thumbnails for a different image. This can happen when the image ids are reused, for example when an image gets deleted and a new one is added using the same id.
Manage Apps > Gallery > Clear Data can fix this problem then.

This is the code to open gallery. However this the same what you have done. Also see the onActivityResult code which I used to retrive the selected image.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),
PHOTO_GALLERY);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PHOTO_GALLERY:
if (resultCode == RESULT_OK) {
Uri selectedImageUri = Uri.parse(data.getDataString());
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(
getApplicationContext().getContentResolver(),
selectedImageUri);
this.postImagePreview.setImageBitmap( bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
}
}
}

private static int RESULT_LOAD_IMAGE = 1;
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
OnActivity Result
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}

try this one
//Put this code on some event
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, REQUEST_CODE);
// When above event fire then its comes to this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode==RESULT_OK && requestCode==1){
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
filePath = cursor.getString(columnIndex);
cursor.close();
// Use it as per recruitment
actualBitmap =BitmapFactory.decodeFile(filePath);
}
}

Try this,
public class SelectPhotoActivity extends Activity {
private static final int SELECT_PICTURE = 1;
private String selectedImagePath="";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivityForResult(intent, SELECT_PICTURE);
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
// here you can set the image
}
}
}
}

Path of selected image is null

I am trying to get the real path of a URI.
First I start the gallery app through an intent:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select picture"), SELECT_IMAGE );
After that the onActivityResult gets called, where I try to get the absolut path of the URI.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (resultCode == RESULT_OK) {
Uri uri;
if (requestCode == SELECT_IMAGE) {
final Uri uri_data = data.getData();
// Get the path from the Uri
final String path = getPathFromURI(uri_data);
if (path != null) {
File f = new File(path);
uri = Uri.fromFile(f);
}
}
}
} catch (Exception e) {
Log.e("FileSelectorActivity", "File select error", e);
}
}
The uri_data contains "content://com.android.providers.media.documents/document/image%3A67", but the resulting path is null.
The pathFromUri method looks like this:
private String getPathFromURI(Uri contentUri) {
String res = null;
String[] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(contentUri, proj, null, null, null);
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
res = cursor.getString(column_index);
}
cursor.close();
return res;
}
Here the column_index is 0, but cursor.getString returns null.
Why does this happen?
I have the permission android.permission.READ_EXTERNAL_STORAGE
EDIT:
So I want to take a picture through the camera app, and the user then chooses the image. So the file should be acutally stored on the phone (which is, since I am testing it on my phone)
EDIT:
Okey, the solution was to request the permissions at runtime...sorry guys

How to get address from gallery in android

I write this code and my code choose one picture from gallery and get data from it but I dont konw how to get image address from Inputstrem or data and store it?
public void loadPic()
{
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==1)
{
try {
Uri selectedImage=data.getData();
InputStream inputStream = getContentResolver().openInputStream(selectedImage);
listItems.add(inputStream.toString());
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
Read filename name like below, use it accordingly.
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
File f = new File(picturePath);
String imageName = f.getName();
Sometimes, you can't get a file from the picture you choose.
It's because the choosen one came from Google+, Drive, Dropbox or any other provider.
The best solution is to ask the system to pick a content via Intent.ACTION_GET_CONTENT and get the result with a content provider.
public void pickImage() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, PICK_PHOTO_FOR_AVATAR);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) {
if (data == null) {
//Display an error
return;
}
InputStream inputStream = context.getContentResolver().openInputStream(data.getData());
//Now you can do whatever you want with your inpustream, save it as file, upload to a server, decode a bitmap...
}
}
I'm not sure if this is exactly what you want, but you can get the image like this:
Uri selectedImage = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), selectedImage);
Once you have the Bitmap, you can see here on how to store it.
EDIT: Try this
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

how to get the Image from Gallery and set into Image view in Fragments?

I have Written code for getting the Image from gallery and set into the Image View but the image is not set.This is my problem suggest me guys
Here is My Code:
btnUpload.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
getActivity().startActivityForResult(i, 1);
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && null != data)
{
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
//int pic=Integer.parseInt(picturePath);
cursor.close();
//ImageView imageView = (ImageView) mFormView.findViewById(R.id.imageView);
ivMan.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
thanks in Advance
Replace getActivity().startActivityForResult(i, 1); with
startActivityForResult(i, 1);
for getting image from gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
Check if you have a proper path if yes than decode the image and set to imageview.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_IMAGE && data != null && data.getData() != null) {
Uri _uri = data.getData();
//User had pick an image.
Cursor cursor = getContentResolver().query(_uri, new String[]{android.provider.MediaStore.Images.ImageColumns.DATA}, null, null, null);
cursor.moveToFirst();
//Link to the image
final String imageFilePath = cursor.getString(0);
cursor.close();
File file = new File(imageFilePath);
if (file.exists()) {
Bitmap bMap = decodeFile(file);
// asset.setImageBitmap(bMap);
asset.setImageBitmap(bMap);
}
}
super.onActivityResult(requestCode, resultCode, data);
}
this will defiantly help you

}
But not works! when i select an picture from gallery nothing happend.
I need select an picture from gallery device and to send other intent.
Somebody have some idea i thanks a lot.

How to pick an image from gallery (SD Card) for my app?

This question was originally asked for Android 1.6.
I am working on photos options in my app.
I have a button and an ImageView in my Activity. When I click the button it would redirect to the gallery and I would be able to select an image. The selected image would appear in my ImageView.
Updated answer, nearly 5 years later:
The code in the original answer no longer works reliably, as images from various sources sometimes return with a different content URI, i.e. content:// rather than file://. A better solution is to simply use context.getContentResolver().openInputStream(intent.getData()), as that will return an InputStream that you can handle as you choose.
For example, BitmapFactory.decodeStream() works perfectly in this situation, as you can also then use the Options and inSampleSize field to downsample large images and avoid memory problems.
However, things like Google Drive return URIs to images which have not actually been downloaded yet. Therefore you need to perform the getContentResolver() code on a background thread.
Original answer:
The other answers explained how to send the intent, but they didn't explain well how to handle the response. Here's some sample code on how to do that:
protected void onActivityResult(int requestCode, int resultCode,
Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case REQ_CODE_PICK_IMAGE:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(
selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
}
}
}
After this, you've got the selected image stored in "yourSelectedImage" to do whatever you want with. This code works by getting the location of the image in the ContentResolver database, but that on its own isn't enough. Each image has about 18 columns of information, ranging from its filepath to 'date last modified' to the GPS coordinates of where the photo was taken, though many of the fields aren't actually used.
To save time as you don't actually need the other fields, cursor search is done with a filter. The filter works by specifying the name of the column you want, MediaStore.Images.Media.DATA, which is the path, and then giving that string[] to the cursor query. The cursor query returns with the path, but you don't know which column it's in until you use the columnIndex code. That simply gets the number of the column based on its name, the same one used in the filtering process. Once you've got that, you're finally able to decode the image into a bitmap with the last line of code I gave.
private static final int SELECT_PHOTO = 100;
Start intent
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
Process result
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream = getContentResolver().openInputStream(selectedImage);
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
}
}
}
Alternatively, you can also downsample your image to avoid OutOfMemory errors.
private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 140;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE
|| height_tmp / 2 < REQUIRED_SIZE) {
break;
}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);
}
You have to start the gallery intent for a result.
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, ACTIVITY_SELECT_IMAGE);
Then in onActivityForResult, call intent.getData() to get the Uri of the Image. Then you need to get the Image from the ContentProvider.
Here is a tested code for image and video.It will work for all APIs less than 19 and greater than 19 as well.
Image:
if (Build.VERSION.SDK_INT <= 19) {
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(i, 10);
} else if (Build.VERSION.SDK_INT > 19) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 10);
}
Video:
if (Build.VERSION.SDK_INT <= 19) {
Intent i = new Intent();
i.setType("video/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(i, 20);
} else if (Build.VERSION.SDK_INT > 19) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 20);
}
.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 10) {
Uri selectedImageUri = data.getData();
String selectedImagePath = getRealPathFromURI(selectedImageUri);
} else if (requestCode == 20) {
Uri selectedVideoUri = data.getData();
String selectedVideoPath = getRealPathFromURI(selectedVideoUri);
}
}
}
public String getRealPathFromURI(Uri uri) {
if (uri == null) {
return null;
}
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
return uri.getPath();
}
Do this to launch the gallery and allow the user to pick an image:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, IMAGE_PICK);
Then in your onActivityResult() use the URI of the image that is returned to set the image on your ImageView.
public class EMView extends Activity {
ImageView img,img1;
int column_index;
Intent intent=null;
// Declare our Views, so we can access them later
String logo,imagePath,Logo;
Cursor cursor;
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
String selectedImagePath;
//ADDED
String filemanagerstring;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img= (ImageView)findViewById(R.id.gimg1);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
//UPDATED
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
TextView txt = (TextView)findViewById(R.id.title);
txt.setText(imagePath.toString());
Bitmap bm = BitmapFactory.decodeFile(imagePath);
// img1.setImageBitmap(bm);
}
}
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = { MediaColumns.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
column_index = cursor
.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
imagePath = cursor.getString(column_index);
return cursor.getString(column_index);
}
}
public class BrowsePictureActivity extends Activity {
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
if( uri == null ) {
return null;
}
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
return uri.getPath();
}
}
For some reasons, all of the answers in this thread, in onActivityResult() try to post-process the received Uri, like getting the real path of the image and then use BitmapFactory.decodeFile(path) to get the Bitmap.
This step is unnecessary. The ImageView class has a method called setImageURI(uri). Pass your uri to it and you should be done.
Uri imageUri = data.getData();
imageView.setImageURI(imageUri);
For a complete working example you could take a look here: http://androidbitmaps.blogspot.com/2015/04/loading-images-in-android-part-iii-pick.html
PS:
Getting the Bitmap in a separate variable would make sense in cases where the image to be loaded is too large to fit in memory, and a scale down operation is necessary to prevent OurOfMemoryError, like shown in the #siamii answer.
call chooseImage method like-
public void chooseImage(ImageView v)
{
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, SELECT_PHOTO);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
if(imageReturnedIntent != null)
{
Uri selectedImage = imageReturnedIntent.getData();
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK)
{
Bitmap datifoto = null;
temp.setImageBitmap(null);
Uri picUri = null;
picUri = imageReturnedIntent.getData();//<- get Uri here from data intent
if(picUri !=null){
try {
datifoto = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), picUri);
temp.setImageBitmap(datifoto);
} catch (FileNotFoundException e) {
throw new RuntimeException(e);
} catch (IOException e) {
throw new RuntimeException(e);
} catch (OutOfMemoryError e) {
