Selected Gallery image not showing in imageview

I was selected the image after it have to set it in the imageview.But it doesn't set it in imageview.
I have posted the relevant code.
EditViewProfileActivity.java
public class EditViewProfileActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
private static final int CAMERA_PICTURE = 1;
private static final int GALLERY_PICTURE = 2;
File destination = null;
String filePath = null;
Bitmap chosenImage;
String imgSelected = null;
ImageView dateBirthImg;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_view_profile_activity);
galImageView = (ImageView) findViewById(R.id.gallery_image_edit_view);
galImageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
choosePictureAction();
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_PICTURE
&& resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
String[] projection = {MediaStore.MediaColumns.DATA};
Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
cursor.moveToFirst();
String selectedImagePath = cursor.getString(column_index);
destination = new File(selectedImagePath);
filePath = selectedImagePath;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(selectedImagePath, options);
final int REQUIRED_SIZE = 200;
int scale = 1;
while (options.outWidth / scale / 2 >= REQUIRED_SIZE
&& options.outHeight / scale / 2 >= REQUIRED_SIZE)
scale *= 2;
options.inSampleSize = scale;
options.inJustDecodeBounds = false;
chosenImage = BitmapFactory.decodeFile(selectedImagePath, options);
if (chosenImage != null) {
imgSelected = "fulFilled";
galImageView.setImageBitmap(chosenImage);
Log.e("ChosenImage", "" + chosenImage);
}
} else if (requestCode == GALLERY_PICTURE
&& resultCode == RESULT_CANCELED) {
}
}
private void choosePictureAction() {
final CharSequence[] items = {"Camera", "Gallery", "Cancel"};
android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(EditViewProfileActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (items[which].equals("Camera")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PICTURE);
} else if (items[which].equals("Gallery")) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, GALLERY_PICTURE);
} else if (items[which].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
}
I dont know why selected image not showing in imageview.Anyone can help me with this.Thank you.

I Have use this code:
private void openGallery() {
Intent gallery =
new Intent(Intent.ACTION_PICK,
android.provider.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) {
Uri imageUri = data.getData();
try {
bitmaps = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
final ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmaps.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] byteArray = stream.toByteArray();
encodeded = Base64.encodeToString(byteArray, Base64.DEFAULT);
byte[] decodedString = Base64.decode(encodeded, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
userinfoimage.setImageBitmap(bitmaps);
new UploadImage().execute();
} catch (IOException e) {
e.printStackTrace();
}
}
}

If you only want to set image in imageview. you can directly use the uri. Like this
String stringUri = selectedImageUri.getPath();
galImageView.setImageURI(null);
galImageView.setImageURI(Uri.parse(stringUri));

Android : Integrating gallery functionality with camera capture

I am working on an Android project in which I have the functionality where user can click on the a button and it will open the camera to upload the image. The upload button is hidden until there is image taken and shown in preview.
What I would like to do is to use the same upload button, which I have set to visible by default now and on clicking it, I would like to open a gallery, which the user can then use to select an image, and it would be shown in preview.
I have a boolean flag to manage this, where if the flag is false, then gallery is opened, else the image in the preview is uploaded.
I have this, but I don't know how to open a gallery and then send the image to preview, to upload. I am new to Android programming, so kindly take that into consideration.
I searched for similar functionality, but the problem is, I have not found, where such features are integrated.
Java code :
RobotoTextView BtnSelectImage;
private ImageView ImgPhoto;
CheckBox profilePhotoCheckBox;
final RestaurantImageServiceImpl restaurantService = new RestaurantImageServiceImpl();
private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;
private static volatile Bitmap reducedSizeBitmap;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
private static boolean galleryFlag = false;
#Override

BtnSelectImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
galleryFlag = true;
captureCameraImage();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
});
uploadImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!(v == null)) {
if(!galleryFlag){
// I think the gallery open code should come here.
}
if (profilePhotoCheckBox.isChecked()) {
uploadImage(true);
}else {

I hope this much information is enough. Can anyone point me which functions I should put and where. Thanks a lot. :-)

Finally the integration works. I had to combine answers from the one I received and here on SO.

Thanks a lot for all your help.. :-)

In Constant file write in my case(ActivityConstantUtils.java)
public static final int GALLERY_INTENT_REQUEST_CODE = 0x000005;
To open Gallery & get path of selected image use following code :
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
photoPickerIntent.setType("image/*");
photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
mActPanelFragment.startActivityForResult(photoPickerIntent, ActivityConstantUtils.GALLERY_INTENT_REQUEST_CODE);
After that you get path in onActivityResult() method
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
(requestCode == ActivityConstantUtils.GALLERY_INTENT_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
try {
String imagePath = getFilePath(data);
// TODO: Here you set data to preview screen
}catch(Exception e){}
}
}
private String getFilePath(Intent data) {
String imagePath;
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imagePath = cursor.getString(columnIndex);
cursor.close();
return imagePath;
}

I sent a content image to QuickBlox server. but when i get back. i found nullPointerError

I am creating a chatting app. and i what to send content(Image, Video, Audio, Location, Contact) in Private and Group. for sending image i used this code
attachInfoButton.setOnClickListener(new OnClickListener() {

issue with onActivityResult in Android

Hi I have created an Activity from that I am calling startActivityForResult at the first time it is working below is the code
Dialog box for choosing image from Camera or Gallery
private void selectImage() {
System.out.println("Select Image");
final CharSequence[] items = { "Take Photo",
"Choose from Library", "Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (items[item].equals("Take Photo")) {
final Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
setImageUri());
startActivityForResult(intent, CAPTURE_IMAGE);
} else if (items[item]
.equals("Choose from Library")) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(
intent, ""), PICK_IMAGE);
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
It's onActivityForResultSetMethod
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
System.out.println("onActivityResult");
System.out.println("requestCode : - " + requestCode);
System.out.println("resultCode : - " + resultCode);
System.out.println("data : - " + data);
if (resultCode != Activity.RESULT_CANCELED) {
if (requestCode == PICK_IMAGE) {
imagePath = getAbsolutePath(data.getData());
bitmap = decodeFile(imagePath);
ivUpload.setScaleType(ImageView.ScaleType.FIT_XY);
ivUpload.setImageBitmap(bitmap);
} else if (requestCode == CAPTURE_IMAGE) {
imagePath = getImagePath();
bitmap = decodeFile(imagePath);
ivUpload.setScaleType(ImageView.ScaleType.FIT_XY);
ivUpload.setImageBitmap(bitmap);
} else {
super.onActivityResult(requestCode, resultCode,
data);
}
}
}
Issue if when i first time called, In image view i am not getting image, and also if i tried it again
Activity's onCreate method is also called don't know but why

Try this way,hope this will help you to solve your problem.
private int PICK_IMAGE=1;

As to called onCreate(), please Log.d("~~~",""+savedInstanceState);, it will likely be non-null meaning that Android advices you to restore the application state from the bundle.

How to get image name of after taking photo or sd card in Android

I am little confusion about how to get image name, when taking photo from camera(Current Click image) or sd card(Already cliked or in the sd card image).Could you please help me out how to get image name.
if (requestCode == CAMERA_REQUEST) {
ImageView profImage;
Bitmap photo = (Bitmap) data.getExtras().get("data");
Bitmap scaledphoto = Bitmap.createScaledBitmap(photo, height, width,
true);
profImage.setImageBitmap(scaledphoto);
//How to get name here
}
Now , Here How to get ImageName for propose of saving image on database.
Or
Imageview test=(Imageview) findViewById(R.id.testimage);
test.setImageResource(R.drawable.androidimage);
So, I want get name of image, Here image name is androidimage.SO How to get imagename.

You can pass the Bitmap to this method to get Image Uri.
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(),
inImage, "Title", null);
return Uri.parse(path);
}
Finally you can set the image to image view with
imageView.setImageUri(mUri);

Please use the following code.
public class UploadImageActivity extends Activity {
private final int CAMERA_PICTURE = 1;
private final int GALLERY_PICTURE = 2;
private ImageView userPictureImageView;
private Intent pictureActionIntent = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
userPictureImageView = (ImageView) findViewById(R.id.imageView1);
userPictureImageView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
startDialog();
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_PICTURE) {
Uri uri = data.getData();
if (uri != null) {
// User had pick an image.
Cursor cursor = getContentResolver().query(uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
// Link to the image
final String imageFilePath = cursor.getString(0);
File photos = new File(imageFilePath);
Bitmap b = decodeFile(photos);
b = Bitmap.createScaledBitmap(b, 150, 150, true);
userPictureImageView.setImageBitmap(b);
cursor.close();
}
else {
Toast toast = Toast.makeText(this, "No Image is selected.", Toast.LENGTH_LONG);
toast.show();
}
}
else if (requestCode == CAMERA_PICTURE) {
if (data.getExtras() != null) {
// here is the image from camera
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
userPictureImageView.setImageBitmap(bitmap);
}
}
}
private Bitmap decodeFile(File f) {
try {
// decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f), null, o);
// Find the correct scale value. It should be the power of 2.
final int REQUIRED_SIZE = 70;
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale++;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
}
catch (FileNotFoundException e) {
}
return null;
}
private void startDialog() {
AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
myAlertDialog.setTitle("Upload Pictures Option");
myAlertDialog.setMessage("How do you want to set your picture?");
myAlertDialog.setPositiveButton("Gallery", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
pictureActionIntent = new Intent(Intent.ACTION_GET_CONTENT, null);
pictureActionIntent.setType("image/*");
pictureActionIntent.putExtra("return-data", true);
startActivityForResult(pictureActionIntent, GALLERY_PICTURE);
}
});
myAlertDialog.setNegativeButton("Camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
pictureActionIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(pictureActionIntent, CAMERA_PICTURE);
}
});
myAlertDialog.show();
}
}
Dont forget to add the camera permission in your manifest file.
