Below is some code which is working somewhat…I currently have 2 ImageViews on my Screen and below each is a button. When the button is clicked the camera function opens. My aim is that the button below one imageviews changes just that image view, leaving me able to then click the other button to change the other. However at the moment when I change one, they both change to the same photo. I had previous tried a few ‘if’ statements by initialising each to a variable called “currentImage” but to no avail.
Any thoughts?
public class NowThen extends Activity {
Bitmap photo;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.nowthen);
}
public void nowPhoto (View view){
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent,0);
}
public void thenPhoto (View view){
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent,0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
if (data != null) {
photo = (Bitmap) data.getExtras().get("data");
ImageView nowImage = (ImageView) findViewById(R.id.nowImage);
ImageView thenImage = (ImageView) findViewById(R.id.thenImage);
nowImage.setImageBitmap(photo);
thenImage.setImageBitmap(photo);
Log.d("camera ---- > ", "" + data.getExtras().get("data"));
}
}
}
}
Change your thenPhoto code to this:
public void thenPhoto (View view){
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent,1);
}
And change your onActivityResult to this :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
if (data != null) {
photo = (Bitmap) data.getExtras().get("data");
ImageView nowImage = (ImageView) findViewById(R.id.nowImage);
nowImage.setImageBitmap(photo);
Log.d("camera ---- > ", "" + data.getExtras().get("data"));
}
} else if (requestCode == 1 && resultCode == RESULT_OK) {
if (data != null) {
photo = (Bitmap) data.getExtras().get("data");
ImageView thenImage = (ImageView) findViewById(R.id.thenImage);
thenImage.setImageBitmap(photo);
Log.d("camera ---- > ", "" + data.getExtras().get("data"));
}
}
}
}
Your code is correct except that you are starting the intent with same requestCode 0. Due to this the same block is called in your onActivityResult() block.
startActivityForResult(intent,0);//for first button
startActivityForResult(intent,1);//for second button
Now check your requestCode in your onAcitivityResult() code in a if or switch statement.

This is my code from the main activity class named Account class wherein when I press the add entry button it will navigate to the next activity which is the AddEntry class
//ADD ENTRY BUTTON
accountBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(Account.this, AddEntry.class);
startActivityForResult(intent,REQUEST_CODE_ADD);
}
});
After it goes to the second activity which is the AddEntry class, a picture would be captured using the user's camera when the ImageView named entryPhoto is clicked
entryPhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent takePhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File tempImage = null;
try {
tempImage = createImage();
} catch (Exception e) {
e.printStackTrace();
}
if (tempImage != null){
Uri uriImage = FileProvider.getUriForFile(c,"com.example.login.fileprovider",
tempImage);
mCurrentPhotoUri = uriImage;
takePhoto.putExtra(MediaStore.EXTRA_OUTPUT,uriImage);
if (ContextCompat.checkSelfPermission(c, Manifest.permission.CAMERA)!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(AddEntry.this,
new String[]{Manifest.permission.CAMERA},
REQ_CODE_CAMERA);
}
else {
startActivityForResult(takePhoto,REQ_CODE_TAKE_PHOTO);
}
}
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == REQ_CODE_TAKE_PHOTO && resultCode == RESULT_OK) {
entryPhoto.setImageURI(mCurrentPhotoUri);
}
Here is the code where I put all the the information inputted by user then send it back to the main activity. In the addPhoto is where I am supposed to put the image to be passed. I only tried passing an image from my drawable because I really don't know how to pass the image captured.
Intent data = new Intent();
data.putExtra("addPhoto",R.drawable.anonymous);
data.putExtra("addName", entryName.getText().toString());
data.putExtra("addRemark", entryRemark.getText().toString());
data.putExtra("addBirthday", entryBirthday.getText().toString());
data.putExtra("addAddress", entryAddress.getText().toString());
data.putExtra("addGender", selectedGender);
data.putExtra("addContactNo", entryContactNo.getText().toString());
data.putExtra("addHobbies", entryHobbies.getText().toString());
data.putExtra("addOtherInfo", entryOtherInfo.getText().toString());
setResult(RESULT_OK,data);
finish();
And this is the code in the onActivityResult in the main activity
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data); //ONACTRESULT OF ADD ENTRY
if (requestCode == REQUEST_CODE_ADD && resultCode == RESULT_OK){
int addPhoto = data.getIntExtra("addPhoto",1);
String addName = data.getStringExtra("addName");
String addRemark = data.getStringExtra("addRemark");
String addBirthday = data.getStringExtra("addBirthday");
String addAddress = data.getStringExtra("addAddress");
String addContactNo = data.getStringExtra("addContactNo");
String addGender = data.getStringExtra("addGender");
String addHobbies = data.getStringExtra("addHobbies");
String addOtherInfo = data.getStringExtra("addOtherInfo");
entryList.add(0,new Entry(addPhoto,addName,addRemark,addBirthday,addGender,addAddress,addContactNo,addHobbies,addOtherInfo));
myAdapter.notifyDataSetChanged();
}
Please I hope you will help me. I am still a beginner but I really want to be good at programming. Thank you in advance.
I think you can pass the Uri directly in bundle of Intent as it extends Parcelable which means it can retrieved as is
Adding
data.putExtra("addPhoto", mCurrentPhotoUri);
Retrieving
Uri photoUri = getIntent().getParcelableExtra<Uri>("addPhoto");
I use Picasso to get an image from the gallery and set it to an ImageView, but it does not do it. Couldn't find a problem. What is the reason? And the interesting thing is that there was no error. I tested the program through my own device.
public class MainActivity extends AppCompatActivity {
String imageUri ;
ImageView img ;
private static final int GALLERY_REQUEST = 9391;
Button b ;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == GALLERY_REQUEST && resultCode == RESULT_OK && data != null) {
imageUri = data.getData().toString() ;
loadImage() ;
}
else
{
super.onActivityResult(requestCode, resultCode, data);
}
}
private void loadImage() {
Picasso.with(this).load(imageUri).fit().centerInside().into(img);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img = (ImageView)findViewById(R.id.image);
b = (Button)findViewById(R.id.button) ; // it is button used to open //a gallery
}
//thins function called when button pressed
public void openGallery(View view) {
Intent i = new Intent(ACTION_PICK,EXTERNAL_CONTENT_URI) ;
startActivityForResult(i,GALLERY_REQUEST);
}
}
You called super.onActivityResult(requestCode, resultCode, data); which is wrong .
Do this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_REQUEST && resultCode == RESULT_OK && data != null) {
Uri selectedImageURI = data.getData();
Picasso.with(this).load(selectedImageURI).fit().centerInside().into(img);
}
else
{
// handle this case
}
}
Problem Solved.
I forgot to add permission used to read external storage.
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.
I call this function:
private void TakePhoto() {
LogService.log(TAG, "inTakePicture");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/BlueSkyBio/media/", "test.jpg");
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
Which takes me on the next onActivityResult:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE) {
if(outputFileUri != null){
LogService.log("MainFragment", outputFileUri.toString());
String path = outputFileUri.toString();
selectedVideoPath = path.substring(7);
LogService.log("in take pic", "selectedImagePath: " + selectedVideoPath);
Intent paintActivity = new Intent(getActivity(), PaintActivity.class);
paintActivity.putExtra("selectedImagePath", selectedVideoPath);
paintActivity.putExtra("isVideo", false);
startActivity(paintActivity);
((FragmentActivity) getActivity()).finish();
} else{
// Toast.makeText(getActivity(), "No picture taken", Toast.LENGTH_SHORT).show();
Intent main = new Intent(getActivity(), FragmentActivity.class);
startActivity(main);
((FragmentActivity) getActivity()).finish();
}
}
}
This works ok, but if i call the intent to take a picture, and then press the back button, if i already took a picture before, it will load that picture, if not, it will crash, because by pressing back, it will not take a picture. What can i do to escape this situation?
I have tried to test:
if(data != null) // instead of: if(outputFileUri != null){
But this will never enter the "else" part of the code.
use these conditions:
private static final int CAMERA_PIC_REQUEST = 1337;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==CAMERA_PIC_REQUEST && resultCode == RESULT_OK){
log.d("something","something");
}
else if (resultCode == Activity.RESULT_CANCELED)
{
log.d("something","something");
}
}
