I want to Achieve the following in my project:
open the Gallery on clicking an Edittext.
select an Image or File in the gallery and get its path into my edittext.
Can anyone tell me how to do this?
On your onActivityResult
Uri uri = intent.getData();
And then grap that uri path this way
MyEditText.setText(uri.getPath());
try this,
For open gallary,
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);
use this method to get image path,
#SuppressWarnings("unchecked")
#Override
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case PICK_IMAGE:
String imagepath = (getAbsolutePath(data.getData()) + "|").split("\\|");
break;
}
}
}
public String getAbsolutePath(Uri uri) {
String[] projection = { MediaColumns.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}

I need to select image from device and it's full path
But I get null value.. this is my Code
any suggestions
private void openPicture() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
String selectedImagePath = getPath(selectedImageUri);
Toast.makeText(this, ""+selectedImagePath, Toast.LENGTH_SHORT).show();
}
}
}
public String getPath(Uri uri) {
if( uri == null ) {
return null;
}
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();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
return uri.getPath();
}
it's return Null value. I need selected image Path.
I have code like this, the problem is when i want to save it to sqlite, the error message shown that i got null in image path.
Here is the main activity
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
System.out.println("Data Image : "+selectedImageUri);
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
image1.setVisibility(View.VISIBLE);
image1.setImageURI(selectedImageUri);
}
}
}
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
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);
}
I use this method to take photos from camera.
private void capturePhoto() {
// save this Uri in a field variable.
uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new ContentValues());
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(intent, CAMERA_REQUEST);
}
then onActivityResult will look like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK){
// use the field Uri, it now points to the path to the image taken from the camera.
}
}
In manifest file set permission
Check permission granted in onActivityResult method and after its granted READ_EXTERNAL_STORAGE
If it has Permission then call doCreatePath() and set the same in onRequestPermissionsResult on permission granted.
void doCreatePath()
{
try {
Uri originalUri = filePath;
String pathsegment[] = originalUri.getLastPathSegment().split(":");
String id = pathsegment[0];
final String[] imageColumns = {MediaStore.Images.Media.DATA};
final String imageOrderBy = null;
Uri uri = getUri();
Cursor imageCursor = getActivity().getContentResolver().query(uri, imageColumns,
null, null, null);
if (imageCursor.moveToFirst()) {
int column_index_data = imageCursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
realPath = imageCursor.getString(column_index_data);
System.out.print("value" + realPath);
}
} catch (Exception e) {
e.printStackTrace();
}
}
It works!.
When to use
// to get image randomly
public static Uri getRandomImage(ContentResolver resolver) {
String[] projection = new String[] { BaseColumns._ID
};
Uri uri = new Random().nextInt(1) == 0 ? Media.EXTERNAL_CONTENT_URI
: Media.INTERNAL_CONTENT_URI;
Cursor cursor = Media.query(resolver, uri, projection, null,
MediaColumns._ID);
if (cursor == null || cursor.getCount() <= 0) {
return null;
}
cursor.moveToPosition(new Random().nextInt(cursor.getCount()));
return Uri.withAppendedPath(uri, cursor.getString(0));
}
and when to use ACTION_GET_CONTENT intent ?
as I want to pick an Image from an android device !
PLease help
If you want to pick an image from teh android gallery then try something like this :
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 100);
and to get back the result you could do something like this :
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);
}
}
}

Try this answer this will work:
public static final int GALLERY_CODE = 322;
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(
intent,
"Select Picture"),
GALLERY_CODE);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//Assinging on corresponding import
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_CODE && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
try {
//add logic for coping file
} catch (Exception e) {
}
}
}
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);
}
I have to launch the image gallery of Android and let the user to select an image. So I want that after the selection, the directory image is returned.
How can I do it?
Thanks.
Michele,
To launch the Intent for image selection from the Gallery, use the following code:
public void imageFromGallery() {
Intent getImageFromGalleryIntent =
new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(getImageFromGalleryIntent, SELECT_IMAGE);
}
Then, once the user has made their selection you get the result in onActivityResult() like so:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch(requestCode) {
case SELECT_IMAGE:
String imagePath = getPath(data.getData());
break;
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
startManagingCursor(cursor);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
getPath() is a function to get the path from the returned URI object. This will return a String with the path you need.
Cheers!
