I have implemented Camera via Intent and set that Image in Imageview which is appearing blurred, while the same Image appear's clear in ImageGallery. The code and related picture are as follows :
Image saved in SD CARD
Blurred image in Imageview
Activity Class :
public class MainActivity extends ActionBarActivity {
Button b1,b2;
ImageView iv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1=(Button)findViewById(R.id.button);
iv=(ImageView)findViewById(R.id.imageView);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Bitmap bp = (Bitmap) data.getExtras().get("data");
iv.setImageBitmap(bp);
}
File is being saved in sdcard and also I retrive its URI sucessfully, but still imageview do not show this image or imageview disappear when camera click and return. Code are as follows -:
public class MainActivity extends Activity {
static int TAKE_PIC =1;
Uri outPutfileUri;
ImageView mImageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageView = (ImageView) findViewById(R.id.image);
}
public void CameraClick(View v) {
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(),
"MyPhoto.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent, TAKE_PIC);
}
Bitmap bitmap = null;
#Override
protected void onActivityResult(int requestCode, int resultCode,Intent data)
{
if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {
String uri = outPutfileUri.toString();
Log.e("uri-:", uri);
mImageView.setImageURI(Uri.parse(uri));
}
}}
Please suggest me how to get path of clicked image and set it to imageview. I am new here.
First of all, the image is blurred because the intent data contains only the thumbnail of the image.
you must save the image on the internal/external storage and then acquire it.
feel free to take a look at the android developers documentation regarding camera images:
Android Developers
and this older SO answer explains how to retrieve the full size image after saving it :
Android get full size image from camera
Try This,
public class MainActivity extends Activity {
static int TAKE_PIC =1;
Uri outPutfileUri;
ImageView mImageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageView = (ImageView) findViewById(R.id.image);
}
public void CameraClick(View v) {
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(),
"MyPhoto.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent, TAKE_PIC);
}
Bitmap bitmap = null;
#Override
protected void onActivityResult(int requestCode, int resultCode,Intent data)
{
if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {
String uri = outPutfileUri.toString();
Log.e("uri-:", uri);
Toast.makeText(this, outPutfileUri.toString(),Toast.LENGTH_LONG).show();
//Bitmap myBitmap = BitmapFactory.decodeFile(uri);
// mImageView.setImageURI(Uri.parse(uri)); OR drawable make image strechable so try bleow also
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), outPutfileUri);
Drawable d = new BitmapDrawable(getResources(), bitmap);
mImageView.setImageDrawable(d);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
Hope this will help you enjoy!!!!!

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) {
}
};
I am creating a app that opens camera for user and after image captured it will be shows on ImageView! But the image in ImageView has very bad quality
here is the code:
public class Camera extends AppCompatActivity implements View.OnClickListener {
ImageView imgView;
Button camera, setBackground;
Intent i;
int cameraData = 0;
Bitmap bitmap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
initialize();
}
private void initialize() {
imgView = (ImageView) findViewById(R.id.bPicture);
camera = (Button) findViewById(R.id.bOpenCamera);
setBackground = (Button) findViewById(R.id.bSetBackground);
camera.setOnClickListener(this);
setBackground.setOnClickListener(this);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
Bundle extras = data.getExtras();
bitmap = (Bitmap) extras.get("data");
Bitmap resizedBmp = Bitmap.createScaledBitmap(bitmap, imgView.getWidth(),imgView.getHeight(), false);
imgView.setImageBitmap(resizedBmp);
}
}
#Override
public void onClick(View v) {
switch(v.getId()){
case R.id.bOpenCamera:
i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, cameraData);
break;
case R.id.bSetBackground:
try {
WallpaperManager wallmngr = WallpaperManager.getInstance(this);
wallmngr.setBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
}
what should I do to increase image quality?
Use something other than the thumbnail. Quoting the documentation for ACTION_IMAGE_CAPTURE, with emphasis added:
The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT.
So, specify a Uri in EXTRA_OUTPUT where a full camera image should be written to. Then, use an image-loading library, like Picasso, to load the photo into your ImageView.
Here is a sample app that demonstrates using EXTRA_OUTPUT.
This is how I made it work for me! Assuming you are capturing an image, and would like to show the captured image in a new Activity, you can follow this way:
First on the click of button you can:
public void cameraFuture(View view) // <-- onClick() method of Camera Button
{
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(),
"MyPhoto.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent, TAKE_PIC);
}
Then on the onActivityResult() method, you can do this way:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PIC && resultCode==RESULT_OK){
Toast.makeText(this, outPutfileUri.toString(),Toast.LENGTH_LONG).show();
Intent bitIntent = new Intent(this, CameraTake.class);
bitIntent.putExtra("imageUri", outPutfileUri);
startActivity(bitIntent);
finish();
}
}
And in the next Activity, you can receive the file this way:
Intent receiveIntent = getIntent();
uri = receiveIntent.getParcelableExtra("imageUri");
if (savedInstanceState == null) {
Bundle extras = getIntent().getExtras();
if(extras == null) {
receiveImg= null;
} else {
receiveImg= extras.getString("PASSER");
}
} else {
receiveImg= (String) savedInstanceState.getSerializable("PASSER");
}
File imgFile = new File(Environment.getExternalStorageDirectory(),"MyPhoto.jpg");
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.camOut);
myImage.setImageBitmap(myBitmap);
}
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
Button takePhoto;
ImageView photo;
static final int Cam_Request = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
photo = (ImageView)findViewById(R.id.ivPhoto);
takePhoto = (Button)findViewById(R.id.btnPhoto);
takePhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = getFile();
camera_intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(file));
startActivityForResult(camera_intent,Cam_Request);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String path = "sdcard/camera_app/image.jpg";
photo.setImageDrawable(Drawable.createFromPath(path));
}
private File getFile()
{
File folder = new File("sdcard/camera_app");
if (!folder.exists())
{
folder.mkdir();
}
File image = new File(folder,"image.jpg");
return image;
}
}
Try this:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
imageView = (ImageView) findViewById(R.id.imageView1);
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo)
}}}
my program captures an image (as bitmap) but I don't know (and couldn't find) how to save it with a custom name at a custom path... Here's my image capture codes. Can I do it? Or is there any way saving it as another data type, not bitmap? some help will be great. Thanks.
public class ShowMessagesPage extends Activity {
final static int CAMERA_RESULT = 0;
DBAdapter db = new DBAdapter(this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_messages_page);
Button userButton = (Button)findViewById(R.id.button1);
userButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
error();
}});
Button buttonPhoto = (Button)findViewById(R.id.buttonPhoto);
buttonPhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_RESULT);
}});}
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK) {
Bundle extras = intent.getExtras();
Bitmap bmp = (Bitmap) extras.get("data");
}
}
and the other codes..........
Try this:
Intent getCameraImage = new Intent("android.media.action.IMAGE_CAPTURE");
File cameraFolder;
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
cameraFolder = new File(android.os.Environment.getExternalStorageDirectory(),"folder_name_of_your_choice");
else
cameraFolder= ShowMessagesPage.this.getCacheDir();
if(!cameraFolder.exists())
cameraFolder.mkdirs();
File photo = new File(Environment.getExternalStorageDirectory(), "folder_name_of_your_choice/camera_snap.jpg");
getCameraImage.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
initialURI = Uri.fromFile(photo);
startActivityForResult(getCameraImage, CAMERA_RESULT);
And in the onActivityResult(), process the Uri initialURI to get your Image which is already saved to the path you have chosen in the code posted above. The name of the image file will be: camera_snap.jpg
Note: The Uri initialURI is declared globally.
how to store the imagePath of the image that I had captured using the camera activity to database. I also need to retrieve that imagePath and display on another activity?
Can someone help me please?
Update:
public class Image_secondPage extends Activity
{
public static final int CAMERA_RESULT = 1;
Button btn1;
ImageView imageView1;
private final String tag = getClass().getName();
#Override

Intent intent = new Intent(Image_secondPage.this, ImagesPage.class);
startActivity(intent);
}
});
PackageManager pm = getPackageManager();
if(pm.hasSystemFeature(PackageManager.FEATURE_CAMERA))
{
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, MyFileContentProvider.CONTENT_URI);
startActivityForResult(i, CAMERA_RESULT);
}
else
{
Toast.makeText(getBaseContext(), "Camera is not available", Toast.LENGTH_LONG).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
Log.i(tag, "Receive the camera result");
if(resultCode == RESULT_OK && requestCode == CAMERA_RESULT)
{
File out = new File(getFilesDir(), "newImage.jpg");
if(!out.exists())
{
Toast.makeText(getBaseContext(), "Error while capturing image", Toast.LENGTH_LONG).show();
return;
}
Bitmap mBitmap = BitmapFactory.decodeFile(out.getAbsolutePath());
imageView1.setImageBitmap(mBitmap);
}
}
#Override
protected void onDestroy()
{
super.onDestroy();
imageView1 = null;
}
I am supposed to get the imagePath that I have captured and show the image on the imageView that I had on the next class but I don't know how. Can someone help me?
try use this
bitmap = (Bitmap) data.getExtras().get("data");
this will give you bitmap image, then you can save it to database or anything you want.
let me know if this not solve your problem.
