im trying to access and select an image from my phone galley onto my application imageView, using android. So far ive managed to set get to the galley and select the image i want to use, the only problem is that once ive selected the image i want i cant get it onto the imageview. the problem seems to be that ive got the imageview class seperate from my main class. ive checked and cant find a solution.
heres the code for the mediagalley class
public class MediaGallery extends Activity {
public static final int SELECT_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == SELECT_IMAGE) {
Uri selectedImage = data.getData();
String path = getPath(selectedImage);
Bitmap bitmapImage = BitmapFactory.decodeFile(path);
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(bitmapImage);
}
}
public String getPath(Uri uri) {
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, filePathColumn, null,null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
return cursor.getString(columnIndex);
}
}
and the main class code
case R.id.gallery_button:
MediaGallery activ1 = new MediaGallery();
Intent gallery = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(gallery, 1);
activ1.onActivityResult(1, 1, gallery);
break;
any help u gave give il be very greatful
You have declared MediaGallery is another Activity. Are you trying to show an ImageView on the same activity from which you select the button to launch the picker, or in a new activity? If the former, put that onActivityResult code into your main class. If the latter, then your main class should pass the Intent data to the MediaGallery class.

I have two activities in one i have a button and in second i have a ImageView, Now i want if i click on first activity's button then i go to gallery and pick an image when i select an image then it will automatically set in second activity's ImageView, My code is working when i set image in same acticity's imageView but i want set the image in second activity's ImageView. Please tell me what code i need to write in SecondActivity, My first Activity is(Select_Image):-
public class Select_Image extends Activity {
Button button;
public static final int PICK_FROM_GALLERY = 100;
Bitmap bitmap;
String imagePath = " ";
Uri uri;
ImageView image;
String path = " ";
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.select_image);
button = (Button)findViewById(R.id.select_btn);
image = (ImageView)findViewById(R.id.edit_image_id); //This is second Activity's ImageView id.
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
galleryIntent();
}
});
}
public void galleryIntent(){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_FROM_GALLERY);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == MainActivity.RESULT_OK) {
if (requestCode == PICK_FROM_GALLERY){
}
onSelectFromGalleryResult(data);
}
}
public void onSelectFromGalleryResult(Intent data){
if (data != null) {
try {
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), data.getData());
}
catch (Exception e) {
e.printStackTrace();
}
}
uri = getImageUri(this, bitmap);
imagePath = getRealPathFromUri(uri);
image.setImageBitmap(bitmap);
}
private String getRealPathFromUri(Uri uri) {
Cursor cursor = null;
try {
String[] proj = {MediaStore.Images.Media.DATA};
cursor = this.getContentResolver().query(uri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String ss = cursor.getString(column_index);
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
}
private Uri getImageUri(Select_Image select_image, Bitmap bitmap) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
Toast.makeText(select_image, "Image uploaded Successfully", Toast.LENGTH_LONG).show();
path = MediaStore.Images.Media.insertImage(select_image.getContentResolver(), bitmap, "Title", null);
return Uri.parse(path);
}
}
Second Activity(MainActivity)
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
In your onActivityResult, you got the result which is used by your current activity. If an image is selected you got your result on onActivityResult.Here, you can pass this imageUrl in your second activity and open image in your second activity. If you have still any doubt you can ask me.
To sum up, you want to interact with Activity A, start a task then receive the result in Activity B, it's impossible. But you can get the same behavior by 2 options:
Start Activity B on Activity A's button clicked. In Activity B's onCreate, start the image selector and get the result from there.
Start the image selector in A's button clicked, get the result and then pass the result to B using startActivity Intent.
Prefer the first option because it makes the code cleaner, Activity B does its own job and Activity A doesn't need to know about it. Moreover, you save some performance when serialize/deserialize the param from A to B, make the activity transition smoother
I want to show the image that taken by user gallery to a canvas to edit it after.but till now i can get image from user.but i dont know how to show the image by canvas
this is my code :
public class second extends ActionBarActivity {
private static int RESULT_LOAD_IMAGE = 1;
Bitmap base;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
}
i know to creat a canvas with Canvas canvas= new Canvas(image) and draw the bitmap by ondraw method.
but still i dont figure out how to convert the photo that given from users gallery to canvas and show it
shouldn't something like this work:
imageView.setImage(yourImage);
imageView.notify();
sry that i had to post thisn as answers, but i dont have enough repfor a simple comment :/
i searched and i found how to can to get image from gallery and show it in image view.this is a my source

i can to show image from gallery in image view,but i have two imageviews and when i click second imageview and choose some image result is first image view.i can't to show image only imageview witch i clicked.
how i can solve my problem? if anyone knows solution please help me
In onActivityResult you use the same variable credouploadcenter1left for both if...
Try:
if(choosebutton==1)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
if(choosebutton==2)
credouploadcenter1.setImageBitmap(BitmapFactory .decodeFile(picturePath));
if(choosebutton==1)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
if(choosebutton==2)
credouploadcenter1left.setImageBitmap(BitmapFactory.decodeFile(picturePath));
Here is the error, independently of your choose, you will set image always on credouploadcenter1left.
You have to set it on centeruploadcenter1 when you choose second button.
I want to attach imageView to send through Android mail services. This is how i get image from Gallery in Activity A:
public class Activity A extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_gallery);
private static int RESULT_LOAD_IMAGE = 1;
Button viewcards=(Button)findViewById(R.id.viewcards);
viewcards.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
{
Uri selectedImage = data.getData();
String[] filePathColumn =
{ MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
Intent newdata = new Intent(SavedCards.this, Cardd.class);
newdata.putExtra("picture_path", picturePath);
startActivity(newdata);
}
}}
Transfer image to another class and and put imageView in Activity B:
public class Activity B extends Activity {
private ImageView cardimage;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.carddd);
String temp = getIntent().getStringExtra("picture_path");
cardimage = (ImageView) findViewById(R.id.cardimage);
cardimage.setImageBitmap(BitmapFactory.decodeFile(temp));
and in Activity B, i want to attach this image into e-mail by onClick.
txtsend=(TextView) findViewById(R.id.txtsend);
txtsend.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
As a reference, how image can attach e-mail is here, but this is to pick from gallery.
How to do this by taken image which is already set on imageView. Thank you.
In your code you setup image to ImageView from file in Activity B. And you know path to this picture file. When you send email just attach this file.
Uri uri = Uri.parse("file://" + attachmentFile);
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
You can use ImageView's getDrawable method see this http://developer.android.com/reference/android/widget/ImageView.html#getDrawable()
So something like,
Bitmap imgViewBmp = ((BitmapDrawable)cardImage.getDrawable()).getBitmap();
Should work.
PS: I would suggest you to first check the api reference docs for any class you want to use. Chances of finding what you are looking for is quite high. Next best thing would be to actually google what you want to solve, if that doesn't work then "rephrase" you words and try again. The chances that you will find your solution are doubled (if not more) with the latter!
I am trying to use Android's built-in gallery. I am able to get the gallery and the albums, but whenever I want to display the image, the gallery straightaway directs me back to my app. I am unable to view the image despite it has been called.
This is my code:
public class CameraTab extends Activity implements OnClickListener{
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera_tab);
ImageButton cameraBtn = (ImageButton)findViewById(R.id.camera_btn);
cameraBtn.setOnClickListener(this);
ImageButton galleryBtn = (ImageButton)findViewById(R.id.gallery_btn);
galleryBtn.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == this.findViewById(R.id.camera_btn)){
/// some codes here
}
if (v == this.findViewById(R.id.gallery_btn)){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
Can anyone please help me? Any help would be appreciated!! Thanks!!
The problem is a misunderstanding of Intent.ACTION_GET_CONTENT intent. It's intented to be used to choose a content (in this case image/*) from the archive.
If you want to show an image, just create a new activity with an ImageView in its layout. Pass the image URI using setData.
I think the Action you want to use is Intent.ACTION_VIEW.
try this
final Intent intent = new Intent(Intent.ACTION_VIEW);
final Uri uri = <The URI to your file>;
// Uri either from file eg.
final Uri uri = Uri.fromFile(yourImageFileOnSDCard);
// or from media store like your method getPath() does but with the URI
// from http://developer.android.com/reference/android/provider/MediaStore.Images.Media.html#EXTERNAL_CONTENT_URI
intent.setDataAndType(uri, "image/*");
startActivity(intent);
The string "image/* is the mime type to be used.
Now the gallery is opened with the given picture selected. To return to your app the user has to press the back button, as usual ;)
private Context context;
public void onCreate(Bundle savedInstanceState) {
...
context = this;
}
I used a scaled Bitmap below because on some devices the images in the Gallery might be too large for being displayed on an ImageView (I had this problem before).
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Bitmap b = new BitmapDrawable(context.getResources(),
selectedImagePath).getBitmap();
int i = (int) (b.getHeight() * (512.0 / b.getWidth()));
bitmap = Bitmap.createScaledBitmap(b, 512, i, true);
// To display the image, you need to set it to an ImageView here
ImageView img = (ImageView) findViewById(R.id.myImageView);
img.setImageBitmap(bitmap);
}
}
}
