I need to capture multiple images and display on the screen
I am able to take a single image and show on image view but I do not know how to display multiple images.
public class MyCameraActivity extends Activity
{
private static final int CAMERA_REQUEST = 1888;
private ImageView imageView;
private static final int MY_CAMERA_PERMISSION_CODE = 100;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
photoButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
{
requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_PERMISSION_CODE);
}
else
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}
});
}

I am trying to get image from phone gallery or capturing image from camera..I have used 'me.villani.lorenzo.android:android-cropimage:1.1.+' for croping the image..It works well for getting image from phone gallery..While Capturing the image from camera,It captured the image but it cannot able to crop..It works fine on Choose from Image from gallery..Here i included my code,please have a look,
public class Details extends AppCompatActivity {
ImageView i1,i2;
Bitmap bitmapPic;
private static int REQUEST_PICTURE = 1;
private final static int REQUEST_PERMISSION_REQ_CODE = 34;
private static int REQUEST_CAMERA = 0, SELECT_FILE = 1, REQUEST_CROP_PICTURE = 2;

android.support.v7.app.ActionBar ab = getSupportActionBar();
if (ab != null) {
ab.hide();
}
i1 = (ImageView)findViewById(R.id.prof1);
i2 = (ImageView)findViewById(R.id.prof2);
i1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectImageOption();
}
});
}
private void selectImageOption() {
final CharSequence[] items = { "Capture Photo", "Choose from Gallery", "Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(Details.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {

startActivityForResult(cropImage.getIntent(this), REQUEST_CROP_PICTURE);
}
}
Captured Image from Camera does not able to crop!Please give me better Solution for this.!Thanks in Advance
Bro, check this out. May solve your problem, you can crop the image from camera / gallery. link
set
<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
android:theme="#style/Base.Theme.AppCompat"/> <!-- optional (needed if default theme has no action bar) -->
to your manifest
call startCropImageActivity(null); in onclick method
this is the method :
private void startCropImageActivity(Uri imageUri) {
CropImage.activity(imageUri)
.setGuidelines(CropImageView.Guidelines.ON)
.setMultiTouchEnabled(true)
.setRequestedSize(320, 320, CropImageView.RequestSizeOptions.RESIZE_INSIDE)
.setMinCropWindowSize(0,0)
.setAspectRatio(1,1)
.setCropShape(CropImageView.CropShape.OVAL)
.start(this);
}
and in onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK) {
((CircleImageView) findViewById(R.id.profileImage)).setImageURI(result.getUri());
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Toast.makeText(this, "Cropping failed: " + result.getError(), Toast.LENGTH_LONG).show();
}
}
}
Here I'm using CircleImageView as circle image
When I try to upload to Firebase my app is crashing with the following error.
I have an 'upload' button that is being used to invoke the camera. Upon clicking it, the image is not uploaded to Firebase.
My code:
private Button mUploadBtn;
private ImageView mImageView;
private static final int CAMERA_REQUEST_CODE = 1;
private StorageReference mStorage;
Uri photoURI;
private ProgressDialog mProgressDialog;
private static final int GALLERY_INTENT = 2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mStorage = FirebaseStorage.getInstance().getReference();
mUploadBtn = (Button) findViewById(R.id.upload);
mImageView = (ImageView) findViewById(R.id.imageView);
mProgressDialog = new ProgressDialog(this);
mUploadBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_REQUEST_CODE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {
mProgressDialog.setMessage("Uplaoding");
mProgressDialog.show();
Uri uri = data.getData();
StorageReference filepath = mStorage.child("Photos").child("file");
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
mProgressDialog.dismiss();
Toast.makeText(MainActivity.this,"Done",Toast.LENGTH_LONG).show();
}
});
}
}
It looks like you're not working with the camera intent correctly. The code you show is expecting that the intent returned by the camera app contains a Uri to the captured image via its getData() method. That's not the way it works.
I recommend you follow this tutorial instead to work with the camera.
override this method
and do the following steps
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK)
{
Uri uri = data.getData();
StorageReference image_path = storageReference.child("Camera Photos").child(uri.getLastPathSegment());
image_path.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(MainActivity.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
}
});
}
}
I don't know why my code which was just working and has suddenly stopped? I want to take a picture through my image button, and then display it in an Image View. Here`s my code that won't display in the Image View:
public class UserInterface extends AppCompatActivity {
private static final int REQUEST_IMAGE_CAPTURE= 1;
private ImageView imageView;
ImageButton cap;
Bundle extras;
Bitmap imageBitmap;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_interface);
imageView = (ImageView)this.findViewById(R.id.imageView1);
cap = (ImageButton) this.findViewById(R.id.cap);
cap.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
extras = data.getExtras();
imageBitmap = (Bitmap) extras.get("data");
imageView.setImageBitmap(imageBitmap);
}
}
}
Uri imageUri;
On your button click listener:
cap.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = Uri.fromFile(new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "IMG_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
takePictureIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
});
On activity result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
imageView.setImageURI(imageUri);
}
}
Do you know how to handle two onActivityResult()s in one activity?
I need to use my camera and search for my photos in one activity.
public class MainActivity extends AppCompatActivity {
public static final int REQUEST_CAPTURE = 1;
Button button_Vyber_Fotku, button_Fotak;
ImageView imageView_VyberFotku, imageView_Fotak;
private static final int PICK_IMAGE = 100;
Uri imageUri_vybrana;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView_VyberFotku = (ImageView) findViewById(R.id.imageView_VyberFotku);
button_Vyber_Fotku = (Button) findViewById(R.id.button_Vyber_Fotku);
imageView_Fotak = (ImageView) findViewById(R.id.imageView_Fotak);
button_Fotak = (Button) findViewById(R.id.button_fotak);
if (!hasCamera())
{
button_Fotak.setEnabled(false);
}
}
public void Vyber_fotku_clicked(View v)
{
openGallery();
}
private void openGallery()
{
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, PICK_IMAGE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE){
imageUri_vybrana = data.getData();
imageView_VyberFotku.setImageURI(imageUri_vybrana);
}
}
public boolean hasCamera()
{
return getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY);
}
public void PouzijFotakClicked(View v)
{
Intent vyfot = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(vyfot , REQUEST_CAPTURE);
}
#Override
protected void onActivityResult(int requestCode1, int resultCode1, Intent data1)
{ if (requestCode1 == REQUEST_CAPTURE && resultCode1 == RESULT_OK)
{
Bundle extras = data1.getExtras();
Bitmap photo = (Bitmap) extras.get("data1");
imageView_Fotak.setImageBitmap(photo);
}
}
}
Instead of two different method for onActivityResults use single method and distinguish them according to their request code.
#Override
protected void onActivityResult(int requestCode1, int resultCode1, Intent data1){
if (requestCode1 == REQUEST_CAPTURE && resultCode1 == RESULT_OK){
Bundle extras = data1.getExtras();
Bitmap photo = (Bitmap) extras.get("data1");
imageView_Fotak.setImageBitmap(photo);
}
else if (resultCode1 == RESULT_OK && requestCode1 == PICK_IMAGE){
imageUri_vybrana = data1.getData();
imageView_VyberFotku.setImageURI(imageUri_vybrana);
}
}
Note: You can't have two declaration for single override method.
// define two variable camera and pick_image of int type pass value of request code of desired out put in activity onResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE){
//first one to pick image
//do somthing
}else if(resultCode == RESULT_OK && requestCode == Camera){
//use to take image from camera response
}
}
Check this
It works for me
private static final int CAMERA_ = 999;
private static final int GALLERY_ = 888;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_) {
if (resultCode == RESULT_OK) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
UtilsClass.mBitmap = BitmapFactory.decodeFile(fileUri.getPath(),
options);
imageView.setImageBitmap(UtilsClass.mBitmap);
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}else if (requestCode == GALLERY_) {
if (resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor c = getContentResolver().query(selectedImage, filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
UtilsClass.mBitmap = (BitmapFactory.decodeFile(picturePath));
imageView.setImageBitmap(UtilsClass.mBitmap);
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}
public class MainActivity extends Activity {
private static final int CAMERA_PIC_REQUEST = 2500;
Button Report_help;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Report_help=(Button)findViewById(R.id.report_help);
Report_help.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
Bitmap image = (Bitmap) data.getExtras().get("data");
ImageView imageview = (ImageView) findViewById(R.id.display_image);
imageview.setImageBitmap(image);
}
}
}
This app captures the image and displays in the imageview.But the problem is after I capture the image and press the back button app crashes.I don't know why is this so? Please anyone help.
I think when you press back button
Bitmap image = (Bitmap) data.getExtras().get("data");
in onActivityResult cause the Null pointer exception error, please catch this one.
Use the below code to check that case.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Uri selectedImageUri = null;
String filePath = null;
switch (requestCode) {
case PICK_Camera_IMAGE:
if (resultCode == RESULT_OK) {
//use imageUri here to access the image
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();
}
break;
}
hope this helps you.
