When I take a picture, the picture will saved on the hard drive and open the picture in imageview.
In my command the picture will be saved but the app is crashing.
public class Note extends Activity {
TextView t;
ImageView iv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.note);
iv=(ImageView) findViewById(R.id.imageView);
Button btn = (Button) findViewById(R.id.photo);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
});
}
public void button (View view){
Intent intent = new Intent(view.getContext(),Note2.class);
startActivityForResult(intent, 0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode==0)
{
Bitmap theImage = (Bitmap) data.getExtras().get("data");
iv.setImageBitmap(theImage);
}}
}
How do I rewrite the command to make it work?
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode==0)
{
Bitmap theImage = (Bitmap) data.getExtras().get("data");
iv.setImageBitmap(theImage);
First, make sure that your Manifest has this permissions:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Second, your onActivityResult method should be like this with declaring a File and store the Bitmap into the device as following:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch(requestCode){
case 0:
final File file = getTempFile(this);
try {
Bitmap captureBmp = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
}
Here is a very good example on capturing images

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 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!!!!!

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?

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.
I am using the following code to use camera by using intent.
In the parameter of intent I am passing android.provider.MediaStore.ACTION_IMAGE_CAPTURE.
It is able to open the camera.
But the problem is that it stops unexpectedly.
The problem is that it gives null pointer exception on OnActivityResults.
I have used the below code:
public class demo extends Activity {
Button ButtonClick;
int CAMERA_PIC_REQUEST = 2;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ButtonClick =(Button) findViewById(R.id.Camera);
ButtonClick.setOnClickListener(new OnClickListener (){
#Override
public void onClick(View view)
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
// request code
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if( requestCode == CAMERA_PIC_REQUEST)
{
// data.getExtras()
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image =(ImageView) findViewById(R.id.PhotoCaptured);
image.setImageBitmap(thumbnail);
}
else
{
Toast.makeText(demo.this, "Picture NOt taken", Toast.LENGTH_LONG);
}
super.onActivityResult(requestCode, resultCode, data);
}
}
Can anyone help me to solve this problem?
Try request code 1337.
startActivityForResult(cameraIntent , 1337);
This how I use it
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1337);
do you have the following declarations in your manifest ?:
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera.autofocus" />
??
I used to do the same...
here is my call to intent:
File file = new File( _path );
Uri outputFileUri = Uri.fromFile( file );
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri );
intent.putExtra( MediaStore.EXTRA_VIDEO_QUALITY,1);
the only slight difference between my and your code - I have file path in URI sending among call
I have used the following code and it worked!
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
final Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
im.setImageDrawable(null);
im.destroyDrawingCache();
Bundle extras = data.getExtras();
Bitmap imagebitmap = (Bitmap) extras.get("data");
im.setImageBitmap(imagebitmap);
}
}
Using intent to use Camera in Android
##
Uri imageUri;
1:-
TextView camera = (TextView)findViewById(R.id.camera);
camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), new Date().getTime() + "myPic.jpg");
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(cameraIntent, IMAGE_CAMERA_REQUEST);}
2:-
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == IMAGE_CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getActivity().getContentResolver().notifyChange(selectedImage, null);
ContentResolver contentResolver = getActivity().getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(contentResolver, selectedImage);
imageDialog(bitmap);
} catch (Exception e) {
Log.e("Camera", e.toString());
}
}
}
}}
I hope it's working for you.
