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);
}
}

I've been trying to pass the image from gallery or from camera to another activity but they don't work properly. If the image from the gallery will work then the image from camera won't work and vice versa. Please help me fix my code. Here are my code for the MainActivity and for the SecondActivity. Thank you!
MainActivity.java
public class MainActivity extends AppCompatActivity {
Button btnStart,btnGallery,btnAbout;
ImageView reademlogo, pianotiles,imgclouds,imgclouds2,imgsharp,imgfclef;
TextView txtread;
Typeface tf1;
private final int REQUEST_IMAGE_CAPTURE = 1;

Uri imageUri;

tf1 = Typeface.createFromAsset(getAssets(),
"fonts/VeganStylPersonalUse.ttf");
txtread.setTypeface(tf1);
}
public void captureImage(View view) {

if (iCamera.resolveActivity(getPackageManager()) != null) {
startActivityForResult(iCamera, REQUEST_IMAGE_CAPTURE);
}
}
public void galImage(View view) {
Intent iGallery = new Intent(Intent.ACTION_PICK,MediaStore.Images.Media.INTERNAL_CONTENT_URI);
iGallery.setType("image/*");
startActivityForResult(iGallery, PICK_IMAGE);
}
#Override

super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK && requestCode == REQUEST_IMAGE_CAPTURE){
Bitmap bitmap = (Bitmap)Objects.requireNonNull(data.getExtras()).get("data");
Intent intent = new Intent(MainActivity.this,Camera.class);
intent.putExtra("Bitmap",bitmap);
startActivity(intent);
}
else if(requestCode == PICK_IMAGE){
if(data != null){
imageUri = data.getData();
Intent intent = new Intent(MainActivity.this,Camera.class);
intent.putExtra("imageUri",imageUri);
startActivity(intent);
}
}
}
}
Camera.java
public class Camera extends AppCompatActivity {
Button btnCap, btnUse;

Uri imageUri;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);

imageView3 = (ImageView) findViewById(R.id.imageView3);
if (getIntent().getExtras() != null) {
imageUri = Uri.parse(getIntent().getStringExtra("imageUri"));
imageView3.setImageURI(imageUri);
}
Intent intentCam = getIntent();
Bitmap camera_img = (Bitmap)intentCam.getParcelableExtra("Bitmap");
if(camera_img != null){
imageView3.setImageBitmap(camera_img);
}
}
}
Try this it is working fine for me.
//Use this method to select image from Gallery
private void processGalleryImage() {
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"),
GALLERY_REQUEST_CODE);
}
//Use this method to click image from Camera
private void processCameraImage() {
Intent cameraIntent = new
Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
}
//Use this method to get image from Gallery/Captured from Camera
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == CAMERA_REQUEST_CODE) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
//Starting activity (ImageViewActivity in my code) to preview image
Intent intent = new Intent(this, ImageViewActivity.class);
intent.putExtra("BitmapImage", photo);
startActivity(intent);
} else if (requestCode == GALLERY_REQUEST_CODE) {
if (data.getData() != null) {
Uri imageUri = data.getData();
//Starting activity (ImageViewActivity in my code) to preview image
Intent intent = new Intent(this, ImageViewActivity.class);
intent.putExtra("ImageUri", imageUri.toString());
startActivity(intent);
}
}
}
}
//ImageViewActivity code
private Bitmap bitmap;
private String uri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_view);
ButterKnife.bind(this);
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
bitmap = bundle.getParcelable("BitmapImage");
uri = bundle.getString("ImageUri");
if (bitmap != null)
imageView.setImageBitmap(bitmap);
else
Glide.with(this).load(uri).into(imageView);
}
}
I am using the Glide library to load image in image view in case if i have image url.
I am making an app that sends a picture taken from the Camera app however the image it returns seems to be only a thumbnail how can I get it to turn the whole image?
The following code gets an image, but it's too small.
public class OnTheJobActivity extends Activity{
private static final int CAMERA_PIC_REQUEST = 1337;
private Button takePictureButton;
private Button sendPictureButton;
private Bitmap thumbnail;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.onthejob);
takePictureButton = (Button) findViewById(R.id.takePictureButton);
takePictureButton.setOnClickListener(takePictureButtonListener);
sendPictureButton = (Button) findViewById(R.id.sendPictureButton);
sendPictureButton.setOnClickListener(sendPictureButtonListener);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.photoResultView);
image.setImageBitmap(thumbnail);
sendPictureButton.setVisibility(Button.VISIBLE);
}
}
private OnClickListener takePictureButtonListener = new OnClickListener() {
#Override
public void onClick(View arg0){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
private OnClickListener sendPictureButtonListener = new OnClickListener() {
#Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, "abc#gmail.com");
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
i.putExtra(Intent.EXTRA_STREAM, thumbnail);
i.setType("image/bmp");
startActivity(Intent.createChooser(i,"Emailfile"));
}
};
}
You could also change the intent you're using.
//in your buttonListener
ContentValues values = new ContentValues();
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//create new Intent
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
try{
startActivityForResult(i, ACTIVITY_GET_IMAGE);
}
catch(Exception ex){
Log.v("BRE", ex.toString());
}
//in your activity
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == ACTIVITY_GET_IMAGE){
if(resultCode == RESULT_OK){
try{String uri = data.getData().toString()}
catch(NullPointerException e){//do something}
}
}
}
This will return a uri which you can then use to access the full resolution image
Try using the implementation shown here
Specifically:
Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
public void onPictureTaken(byte[] imageData, Camera c) {
}
};
My Main2Activity class
public class Main2Activity extends AppCompatActivity {
private static int PICK_IMAGE_REQUEST = 1;
ImageView imgView;
static final String TAG = "Main2Activity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
}
public void loadImagefromGallery(View view) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && null != data) {
final Uri uri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
int nh = (int) (bitmap.getHeight() * (1024.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 1024, nh, true);
imgView = (ImageView) findViewById(imageView);
imgView.setImageBitmap(scaled);
Button button3 = (Button) findViewById(bt_tab3);
button3.setOnClickListener
(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Main3Activity.class);
intent.setData(uri).addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
});
} else {
Toast.makeText(this, "No.", Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Oops! Sorry", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
}
And the Main3Activity
public class Main3Activity extends AppCompatActivity {
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
imageView = (ImageView) findViewById(R.id.imageView2);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Uri imageUri = getIntent().getData();
imageView.setImageURI(imageUri);
}
}
How can I show same gallery image in MainActivity and another Activity?
Move your Button related codes into onCreate() and send Uri as String using intent extras.
Update Main2Activity as below:
public class Main2Activity extends AppCompatActivity {
static final String TAG = "Main2Activity";
private static int PICK_IMAGE_REQUEST = 1;
ImageView imgView;
Button button3;
Uri imageUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
imgView = (ImageView) findViewById(R.id.imageView);
button3 = (Button) findViewById(R.id.bt_tab3);
button3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Main3Activity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivity(intent);
}
});
}
public void loadImagefromGallery(View view) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && null != data) {
// Get uri
imageUri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
int nh = (int) (bitmap.getHeight() * (1024.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 1024, nh, true);
// Set image
imgView.setImageBitmap(scaled);
} else {
Toast.makeText(this, "No.", Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Oops! Sorry", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
}
Get Uri as string from intent and construct Uri from string using Uri.parse() method.
Update Main3Activity as below:
public class Main3Activity extends AppCompatActivity {
ImageView imageView;
Uri imageUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
imageView = (ImageView) findViewById(R.id.imageView2);
if (getIntent().getExtras() != null) {
imageUri = Uri.parse(getIntent().getStringExtra("imageUri"));
imageView.setImageURI(imageUri);
}
}
}
Pass the file path from the uri as String like this to Main3Activity.
button3.setOnClickListener
(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Main3Activity.class);
intent.putExtra("filePath", uri.getPath());
startActivity(intent);
}
});
And in Main3Activity get the data passed from the calling Activity like this.
public class Main3Activity extends AppCompatActivity {
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
imageView = (ImageView) findViewById(R.id.imageView2);
File file = new File(getIntent().getStringExtra("filePath"));
setImageFromFileIntoImageView(file);
}
private void setImageFromFileIntoImageView (File imgFile)
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
imageView.setImageBitmap(myBitmap);
}
}
}
You need to add the following permission in your AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
based on you not accepting previous answers here is a different approach :
first convert your image to byte array like :
Bitmap bm = BitmapFactory.decodeFile("/path/to/image.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is bitmap object
byte[] b = baos.toByteArray();
then convert that into string like :
String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);
then from your first activity make an intent and put that string as an extra like:
Intent imageIntent = new Intent(context,Main3Activity.class);
imageIntent.putExtra("image",encodedImage);
startActivity(imageIntent);
and after that it is so easy to get this string in the next activity using getIntent and then getExtra
hope this helps.
I am trying to take a picture and set it in my MainActivity to an ImageView.
I want to have my camera activity as a seperate class so i tried the following:
MainActivity:
public void onClick(View v) {
switch (v.getId()) {
case R.id.action_button:
Intent camera = new Intent(MainActivity.this,Camera.class);
startActivityForResult(camera ,CAMERA_IDENTIFITER);
break;
default:
break;
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
Log.d("onActivityResult","Sucessfully callbacked!"); //This one wont be executed!
switch(requestCode) {
case (CAMERA_IDENTIFITER) : {
if (resultCode == Activity.RESULT_OK) {
Bitmap bitmap = (Bitmap) data.getParcelableExtra(MediaStore.EXTRA_OUTPUT);
mImageView.setImageBitmap(bitmap);
}
break;
}
}
}
And this is my camera Activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);
takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
pm = getPackageManager();
}
#Override
protected void onStart() {
super.onStart();
if(!isFromActivityResult){
dispatchTakePictureIntent();
}
}
public void dispatchTakePictureIntent() {
if (takePictureIntent.resolveActivity(pm) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch {...}
if (photoFile != null) {
pictureTaken = true;
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
try {
bitmap = ImageFileHandler.handleSamplingAndRotationBitmap(this, Uri.fromFile(new File(mCurrentPhotoPath)));
//mImageView.setImageBitmap(bitmap);
resultIntent = new Intent();
resultIntent.putExtra(MediaStore.EXTRA_OUTPUT,
bitmap);
setResult(Activity.RESULT_OK, resultIntent);
Log.d("onActivityResult","finish() executed!"); //This one gets executed!
finish();
} catch {...}
}
}
The camera intent is starting properly but when i take a picture i dont get back to the onActivityResult in my MainActivity , i'm stuck in the Camera intent.
Your onStart() gets called after onActivityResult() is being executed. Hence starting camera intent again and again. Put Logs and test your self.
To solve the issue
Keep a boolean variable in your activity isFronActivityResult. Keep default value as false and do isFromActivityResult = true; inside onActivityResult(). In onStart do the following:
#Override
protected void onStart() {
super.onStart();
if(!isFromActivityResult)
dispatchTakePictureIntent();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
try {
bitmap = ImageFileHandler.handleSamplingAndRotationBitmap(this, Uri.fromFile(new File(mCurrentPhotoPath)));
//mImageView.setImageBitmap(bitmap);
resultIntent = new Intent();
resultIntent.putExtra(MediaStore.EXTRA_OUTPUT,
bitmap);
setResult(Activity.RESULT_OK, resultIntent);
isFromActivityResult = true;// add this line
finish();
} catch {...}
}
}
i have a button and when click, open camera take photo,the photo save in the sdcard and when i pass it in image view float right i cant understand why, can anybody help please,i want to display the photo with the Height and weight i have in ImageView from layout and only with the camera 2 work with the camera one does work i mean the photo is saved but not display in the image view the code is here
