Is there a way that I can change ImageView of Main.class class through Gallery.class?
my Main class onClick calls the method setImage of Gallery.class
public void setImage(int currentView) {
Log.d("fgdsf","dumaan dito");
this.currentView = currentView;
Intent gallery = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, RESULT_LOAD_IMAGE);
}
and this is the onActivityResult
#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();
LayoutInflater inflater = (LayoutInflater) mActivity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.activity_main, null);
if (currentView == 0) {
ImageView imageView = (ImageView) v
.findViewById(R.id.imageView1);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
if(currentView==1)
{
ImageView imageView = (ImageView) v
.findViewById(R.id.imageView2);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
}
and I get this error
08-07 08:35:08.208: E/AndroidRuntime(15689): Caused by: java.lang.NullPointerException
08-07 08:35:08.208: E/AndroidRuntime(15689): at android.app.Activity.startActivityForResult(Activity.java:3370)
I don't think you can. You can only control the layout of your current activity, along with its components. Since the component isn't on the view of your current Activity (in your case is Gallery), accessing it will throw the NullPointerException. What you can do is, pass the path of the selected image on you Gallery to the Main class then retrieve the image path and set it to your ImageView.
I think your best option is to set an interface in Gallery.class, like
public class Gallery extends Activity {
public interface MyClickListener {
public void OnClick();
}
private MyClickListener listener;
Then in your onClick, set your OnClick ( listener.OnClick() ). In Main.class you will have to import 'MyClickListener' and define whatever actions you want to perform.
For capture Image
This is happens from android 4.0 onward
Before it was returning the image uri path, but now it returns Bitmap from gallery.
So to resolve this.
File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".jpg");
Uri imgUri = Uri.fromFile(file);
String imagepath = file.getAbsolutePath();
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imagepath);
startActivityForResult(intent, CAPTURE_IMAGE);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_CANCELED) {
if (requestCode == CAPTURE_IMAGE) {
imgUser.setImageBitmap(BitmapFactory.decodeFile(imagepath);
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}
For Pick Image From Gallary
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);
public String getAbsolutePath(Uri uri) {
String[] projection = { MediaColumns.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_CANCELED) {
if (requestCode == PICK_IMAGE) {
imgUser.setImageBitmap(BitmapFactory.decodeFile(getAbsolutePath(data.getData()));
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}

pass selectedImage URI in Other Activity and using intent and use same code for generate the Bitmap with that URI
I have Written code for getting the Image from gallery and set into the Image View but the image is not set.This is my problem suggest me guys
Here is My Code:
btnUpload.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);
getActivity().startActivityForResult(i, 1);
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && null != data)
{
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]);
String picturePath = cursor.getString(columnIndex);
//int pic=Integer.parseInt(picturePath);
cursor.close();
//ImageView imageView = (ImageView) mFormView.findViewById(R.id.imageView);
ivMan.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
thanks in Advance
Replace getActivity().startActivityForResult(i, 1); with
startActivityForResult(i, 1);
for getting image from gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
Check if you have a proper path if yes than decode the image and set to imageview.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_IMAGE && data != null && data.getData() != null) {
Uri _uri = data.getData();
//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);
cursor.close();
File file = new File(imageFilePath);
if (file.exists()) {
Bitmap bMap = decodeFile(file);
// asset.setImageBitmap(bMap);
asset.setImageBitmap(bMap);
}
}
super.onActivityResult(requestCode, resultCode, data);
}
this will defiantly help you
I am facing a problem in selecting the image from a gallery and setting it into the imageview. Suppose I have two activities; mainActivity containing buttons for gallery and secondactivity containing the imageview in which the image has to be displayed.
b1.setOnClickListener(new OnClickListener() {
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);
}
});
Please give me the individual code for both....
here is the code to load an image from gallery:
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
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));
}
}
}
with Picasso it can be done in single line and You dont need to make cursor query
I have extended it for better understanding :-
Pick Image
public void pickImage() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
}
Load Image
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageURI = data.getData();
Picasso.with(MainActivity1.this).load(selectedImageURI).noPlaceholder().centerCrop().fit()
.into((ImageView) findViewById(R.id.imageView1));
}
}
}
In my case work this solution
private void OpenGallery(){
Intent getImageIntent = new Intent(Intent.ACTION_GET_CONTENT);
getImageIntent .setType("image/*");
startActivityForResult(getImageIntent , IMAGE_PICKER );
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== IMAGE_PICKER && resultCode == RESULT_OK) {
Uri fullPhotoUri = data.getData();
imageView.setImageURI(fullPhotoUri);
}
}
You can share URI using putExtra("fullPhotoUri", fullPhotoUri.toString()) between activities.
Try this.
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
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));
}
}
Here some examples
http://viralpatel.net/blogs/pick-image-from-galary-android-app/
http://www.coderzheaven.com/2012/04/20/select-an-image-from-gallery-in-android-and-show-it-in-an-imageview/
To Pick Image from gallery, use this code.
btn_imageSetter.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), IMAGE_PICKER);
}
});
Now use this Method to Set the image to the ImageViewer
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == IMAGE_PICKER && resultCode == RESULT_OK && null != data) {
try{
final Uri uriImage = data.getData();
final InputStream inputStream = getContentResolver().openInputStream(uriImage);
final Bitmap imageMap = BitmapFactory.decodeStream(inputStream);
iv_image.setImageBitmap(imageMap);
}
catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(context, "Image was not found", Toast.LENGTH_SHORT).show();
}
}
}
I have an activity, which has a button. When I click on the button it redirects me to the image gallery. I want to show the selected image in the next activity using an image view. But it is not displaying the image. The view is off screen when the image is set.
My code for selecting image and moving on next is given below. I am using no history true in my activities.
#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();
if (!(picturePath.equals(""))) {
Intent intent = new Intent();
intent.setClass(MainActivity.this, ImageInGellary.class);
intent.putExtra("picturePath", picturePath);
startActivity(intent);
}
}
}
public class ImageInGellary extends Activity {
Button cancel;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.load_image);
cancel = (Button) findViewById(R.id.buttonCancelPicture);
Intent in = getIntent();
savedInstanceState = in.getExtras();
String picturePath = savedInstanceState.getString("picturePath");
ImageView imageView = (ImageView) findViewById(R.id.img_view);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
cancel.setOnClickListener(new OnClickListener() {
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);
*/
Intent intent = new Intent();
intent.setClass(ImageInGellary.this, MainActivity.class);
startActivity(intent);
}
});
}
}
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
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));
}
}
}
To support android 11 you need to add this code in AndroidMainfest.xml
<queries>
<intent>
<action android:name="android.intent.action.GET_CONTENT" />
<data android:mimeType="image/*"/>
</intent>
</queries>
If you want to achieve it in 1 line then all you need to do is :
Picasso.with(MainActivity.this).load(data.getData()).noPlaceholder().centerCrop().fit().into((ImageView) findViewById(R.id.imageView1));
Complete Solution :-
Pick Image
public void pickImage() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
}
Load Image
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
//Get ImageURi and load with help of picasso
//Uri selectedImageURI = data.getData();
Picasso.with(MainActivity1.this).load(data.getData()).noPlaceholder().centerCrop().fit()
.into((ImageView) findViewById(R.id.imageView1));
}
}
}
In your situation you need to pass ImageURI to next activity
Uri selectedImageURI = data.getData();
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_GET_CONTENT);
gallery.setType("image/*");
startActivityForResult(gallery, 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){
Uri imageUri = data.getData();
imgView.setImageURI(imageUri);
}
}
I have solved your problem. After the image is picked, convert the image Uri to String and on your second class, convert your string back to image.

http://whats-online.info/science-and-tutorials/49/Android-passing-multiple-data-from-one-activity-to-another/
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK){
Uri selectedImage = data.getData();
if(selectedImage !=null){
Intent intent=new Intent(MainActivity.this, Activity2.class);
Bundle extras = new Bundle();
extras.putString("image", selectedImage.toString());
intent.putExtras(extras);
startActivity(intent);
}
}
}
Activity2.class
Bundle extras = getIntent().getExtras();
String name = extras.getString("image");
Uri imageFinal=Uri.parse(name);
Im trying to do this:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && 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();
Bitmap bmp = BitmapFactory.decodeFile(picturePath);
b[1].setCompoundDrawablesWithIntrinsicBounds(null, new BitmapDrawable(bmp), null, null);
}
But it wont set the image, no matter what. I have tried several different methods too, like using an imagebutton instead of a button and using:
imageButton.setImageBitmap(bmp)
The gallery opens fine and and the callback comes to onActivityResult(...)
but the image wont appear on the button, I have an array of buttons.
I made a rapid test. The following code works for me. If with this you still can't set the image I would check if there's a layout problem (i.e. the image is set but there's no room to show it).
activity_main.xml has just an ImageButton set to wrap_content, inside the main layout which is match_parent.
public class MainActivity extends Activity {
ImageButton imgButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imgButton = (ImageButton) findViewById(R.id.imgButton);
imgButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RESULT_CANCELED) return;
ParcelFileDescriptor fd;
try {
fd = getContentResolver().openFileDescriptor(data.getData(), "r");
} catch (FileNotFoundException e) {
e.printStackTrace();
return;
}
Bitmap bmp = BitmapFactory.decodeFileDescriptor(fd.getFileDescriptor());
imgButton.setImageBitmap(bmp);
}
}
