I would like to allow the user to pock only one image that can be referenced via a uri, I've successfully done this through the following code:
private static final int PICK_IMAGE_REQUEST = 1;
private Uri imageUri;
// Choose file extended from BottomTabView, opens all images on device
public static void openFileChooser(Context context) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
((Activity) context).startActivityForResult(intent, PICK_IMAGE_REQUEST);
// Slide Animation
((Activity) context).overridePendingTransition(R.anim.slide_in_up, R.anim.nothing);
}
// TODO: Is it better to use bitmap or URI
// Check if user has selected file and describe next step
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
// Retrieve image as a URI
imageUri = data.getData();
// Pass image URI to an intent and start activity
Intent intent = new Intent(this, UploadImageActivity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivity(intent);
// Slide Animation
overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);
this.finish();
}
}
The above code opens the following:

Question: How can I achieve something more like the "Custom Gallery"?
if you want to custom layout pick image, you need:
create a screen and using recyclerView to make the layout as you want
get all picture gallery (https://stackoverflow.com/a/25957752/10153377)

I want to create an application that picks the image from gallery automatically according to its name. The user needs to sign in a signaturepad that he can save on the device and when he clicks on the button to save the image, the app automatically picks this image from gallery and display it on an imageview. I created one where I need to pick the image manually (with a little bit of help), this is my code so far:
private void SelectImage()
{
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*"); //Can I define here the name of the image that I want to be selected?
startActivityForResult(intent, PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && null != data){
imageUri = data.getData();
imageView1.setImageURI(imageUri);
}
}
I'm currently learning how to use android studio in java and am trying to make a social media app. I am currently creating an edit profile page where the user would update their details and upload a profile picture.
I have been following tutorials online and all of the ones I have come across use the startActivityForResult method. It has been crossed out and wont call the method as it is deprecated. But I don't know what to use instead.
`ProfileImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//open gallery
Intent OpenGalleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(OpenGalleryIntent, 1000);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #androidx.annotation.Nullable Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1000){
if(resultCode == Activity.RESULT_OK){
Uri imageUri = data.getData();
ProfileImage.setImageURI(imageUri);
UploadImageToFirebase(imageUri);
}
}
}
private void UploadImageToFirebase(Uri image){
StorageReference fileRef = storageReference.child("Profile.jpg");
fileRef.putFile(image).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(Edit_Profile.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
}
});`
I know there is an alternative but I don't understand how it works.
startActivityForResult is indeed deprecated in later versions of AndroidX Activity and Fragment APIs (while I believe you can still use it despite of warning). New way to get result from activity is registerForActivityResult.
In your code you would need to create a launcher, which will handle result (selected image)
private final ActivityResultLauncher<Intent> launcher = registerForActivityResult(
new ActivityResultContracts.StartActivityForResult(),
result -> {
if (result.getResultCode() == Activity.RESULT_OK
&& result.getData() != null) {
Uri photoUri = result.getData().getData();
//use photoUri here
}
}
);
and then launch this launcher in onClickListener
profileImage.setOnClickListener(view -> {
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
launcher.launch(intent);
});
Yes startActivityForeResult is deprecated.
Now you can use ActivityResultLauncher for the callbacks

I would like to select multiple images and display these images into different separate ImageViews. I select a multiple images, but it shows the same image view. Please help I'm really stuck.
For Example. if the user selects 2 pic direct set into imageview 1 and imageview 2
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_BROWSE_PICTURE);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_BROWSE_PICTURE){
if (data.getData() != null) {
Uri selectedImage = data.getData();
ivImage1.setImageURI(null);
ivImage1.setImageURI(selectedImage);
}
}
}
}
First try to get all images data.getClipData - check out this answer
store this to an arraylist for Recyclerview
Show selected image
create multiple image views instead of single one. ivImage1, ivImage2 etc or use Images in RecyclerView
Get all Uris:
ClipData clip = data.getClipData();
for(int i = 0; i < clip.getItemCount(); i++) {
ClipData.Item item = clip.getItemAt(i);
Uri uri = item.getUri();
urilist.add(uri);
}
Then pass the urilist to a listView or recyclerView adapter.
i'm writing an android app on java and need to let my users select and crop images from the gallery.
There is no problem when choosing an image from any native gallery, but when a user chooses to eater crop or choose an image from google photos app the app crushes.
I cannot figure out what is the source of the problem so any answer will be helpful
this is the code i'm using
class fields:
private Uri imageUri;
opening the camera:
private void camOpen() {
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(Environment.getExternalStorageDirectory(), "file" + String.valueOf(System.currentTimeMillis()) + ".png");
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
imageUri = Uri.fromFile(f);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
i.putExtra("return-data", true);
startActivityForResult(i, CAMERA_CODE);
}
opening the gallery:
private void galleryOpen() {
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(Intent.createChooser(i, "select file"), SELECT_PHOTO_CODE);
}
cropping the image:
private void cropImage() {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(imageUri, "image/*");
cropIntent.putExtra("crop", true);
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("return-data", true);
startActivityForResult(cropIntent, CROP_CODE);
} catch (Exception e) {}
}
the result handler:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CODE && resultCode == Activity.RESULT_OK) {
cropImage();
} else if (requestCode == SELECT_PHOTO_CODE && resultCode == Activity.RESULT_OK) {
if (data != null) {
imageUri = data.getData();
cropImage();
}
} else if (requestCode == CROP_CODE && resultCode == Activity.RESULT_OK) {
Bundle bundle = data.getExtras();
Bitmap b = bundle.getParcelable("data");
hasImageChanged=true;
ivProfilePic.setImageBitmap(b);
capturedImage = b;
}
}
thank you for any useful help...
Android does not support crop intent because croping is not part of android api.
So i recommend you for Using library
the issue was with the crop intent. I ended up using the uCrop library and it fixed the problem.
I have implemented adding multiple image selection from the gallery in my project. However, I want to limit the user so he/she can select only 3 images from the gallery.
I have implemented selecting multiple images from the gallery like this:
`Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), 1);`
How can I achieve this?
Thanks.
You can get the count of ClipData when selecting multiple images from and gallery and if that count is greater than 3 you can notify the user about it.
You can do something like this after selecting images from gallery:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK || resultCode != RESULT_CANCELED){
ClipData clipData = data.getClipData();
if(clipData.getItemCount() > 3){
//notify user here...
}
}
}
This is not possible.

You'll have to manually check the returned data to see if it's more than 10 items, and if so, show a Toast
put this in your build.gradle(app)
compile 'com.github.esafirm.android-image-picker:imagepicker:1.5.0'
compile 'com.github.esafirm.android-image-picker:rximagepicker:1.5.0'
and this in your activity
private void pickImage() {
ImagePicker.create(UploadPhotosActivity.this)
.showCamera(false)
.limit(3)
.imageTitle(getString(R.string.select_image))
.folderTitle(getString(R.string.folder))
.theme(R.style.ImagePickerTheme)
.start(RC_CODE_PICKER);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_CODE_PICKER) {
Log.d("===uploadPhoto", "gallery : " + data);
imagesList = (ArrayList<Image>) ImagePicker.getImages(data);
Intent intent = new Intent(UploadPhotosActivity.this, ImageCropperActivity.class);
intent.putExtra(ImageCropperActivity.EXTRA_VIEW_PORT_RATIO, imagesList);
startActivity(intent);
}
} else {
Intent returnIntent = new Intent();
setResult(Activity.RESULT_CANCELED, returnIntent);
finish();
}
}
