These codes can only capture and display image I took, and when I pressed save button, it only saves "Note title" onto my list View. And when I clicked "Note Title" it doesn't display the picture anymore. What should I add to save it and update it? Thanks.
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap mphoto = (Bitmap) data.getExtras().get("data");
imageviewid.setImageBitmap(mphoto);
}
}
public void takeImageFromCamera(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
private void saveNote(){
fillNameIfEmpty();
id = DbAccess.addNote(getBaseContext(), etName.getText().toString(), mFileName, DbContract.NoteEntry.TYPE_PHOTO, currentCat);
Toast.makeText(getApplicationContext(), R.string.toast_saved, Toast.LENGTH_SHORT).show();
}
private void updateNote(){
fillNameIfEmpty();
DbAccess.updateNote(getBaseContext(), id, etName.getText().toString(), mFileName, currentCat);
Toast.makeText(getApplicationContext(), R.string.toast_updated, Toast.LENGTH_SHORT).show();
}
Your DbAccess API doesn't know anything about an image in the note!
So I would extend your code to:
After picture is taken it saved in fail in application sandbox
Save filename of image assigned to note to database together with note
And don't forget to handle editing or deletion picture use cases!

I am working on a semester project and it requires that I send images from an android device to server without storing the image. I want to make sure my cameta application is working properly. I want to check this using an ImageView that displays the captured image on the screen. How can I do it? I thought I could load from drawable but I cannot add files to drawable during runtime.
Thanks for any support
You don't need to save it to the drawable. These are the two steps:
1.Convert the captured image to Bitmap
2.Set the bitmap image to an imageview
Ref: StackOverflow Answer
private void takePicture(){ //you can call this every 5 seconds using a timer or whenever you want
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap picture = (Bitmap) data.getExtras().get("data");//this is your bitmap image and now you can do whatever you want with this
imageView.setImageBitmap(picture); //for example I put bmp in an ImageView
}
}
I have an app where a user can find an image from the gallery and it will be shown on the screen through a button click. The user can exit the app and the image they chose can be saved, so when they click the button again, it will also be shown. The image is shown the first time when it is picked, but the saving functionality does not seem to be working since the image is not being shown after the user closes and reopens the app.
I have tried looking up what camera permissions I may need, but I have not had any luck. I don't know what I would need since the app is able to load the image the first time.
//This is the method that shows the image
public void showImage(View view)
{
LinearLayout scroll = findViewById(R.id.imageViewer);
for(String i: imgDataList){
ImageView image = new ImageView(this);
image.setImageURI(Uri.parse(i));
scroll.addView(image);
}
}
//This is the method that works with the image that is gotten from the gallery
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
String imgData = data.getDataString();
switch(requestCode) {
case 0:
if(resultCode == RESULT_OK){
imgDataList.add(imgData);
}
break;
case 1:
if(resultCode == RESULT_OK){
imgDataList.add(imgData);
}
break;
}
you may use sharedPreferences to store you image uri
please read more here about sharedPreferences and Save key-value data
I am taking photo from my activity using camera intent as shown in the below code, but i need to use the captured image bitmap outside the onActivityResult() method but this is not working, i tried to declare the bitmap outside the method and then use outside the method but this did not work, it seems that the bitmap did not catch the image in the onActivityResult, so can anyone help in order to use the bitmap of captured image outside the method or to save it and get its path like using the select image from gallery, so my goal is to use the bitmap of captured image for image processing purpose outside the onActivityResult() method, below is my code, thanks
captureButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
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);
}
}
});
and this the onActivityResult() method:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageSelected.setImageBitmap(photo);
}
}
I tried this steps and it worked for me
1) define a Bitmap Object above of your onCreate method like bellow
Bitmap photo;
2) instead of Bitmap photo = (Bitmap) data.getExtras().get("data"); in onActivityResult write bellow code
photo = (Bitmap) data.getExtras().get("data");
and after that you can access to your photo object everywhere in your activity you like
I am making a activity whereby i ask the user to load image from various sources and showing the selected image on a imageview in a different activity.
I am able to show the image from the camera and gallery but from dropbox it is showing error.
For Camera and gallery i can even query the uri obtained from
intent.getData()
in the onactivityresult method and obtain the Filepath and accordingly even obtain the bitmap and resize it .
But the same is not working for Dropbox. Kindly update what code to use for Dropbox so that all options start working.
thanks
For Dropbox you will need to use their Android Chooser to choose files from the user's Dropbox account. You will need a Dropbox API key for this. Once you have grabbed the chooser library and your API key it should be fairly easy to implement;
private Button mChooserButton;
private DbxChooser mChooser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mChooser = new DbxChooser(APP_KEY);
mChooserButton = (Button) findViewById(R.id.chooser_button);
mChooserButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mChooser.forResultType(DbxChooser.ResultType.PREVIEW_LINK)
.launch(MainActivity.this, DBX_CHOOSER_REQUEST);
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == DBX_CHOOSER_REQUEST) {
if (resultCode == Activity.RESULT_OK) {
DbxChooser.Result result = new DbxChooser.Result(data);
Log.d("main", "Link to selected file: " + result.getLink());
// Handle the result
} else {
// Failed or was cancelled by the user.
}
} else if (requestCode == GALLERY) {
// If your request was from the user gallery
Log.d("main", "Link to selected file: " + data.getData());
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
in my app i m calling built in camera for capturing picture but i want to set that picture into an image view following is the code . so what code should i add to it to set the picture into imageview.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == 0) {
String result = data.toURI();
// ...
}
}
Thanks in advance
Add a button and an ImageView to your main layout. When you click the button, first intent.putExtra to specify where the image will be stored, then start the camera intent. In your onActivityResult, if the resultCode comes back 0 that means the user accepted the picture. In this case, go grab the image from the path you specified as an extra of the intent. Create a bitmap from the file specified by the path, then set the image bitmap in your ImageView.
