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.

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));

I am naive in android.I am facing a nuNullPointerException when i picking an image from the gallery.my code is following like that and getting error in cursor and filePathColumn[0]. What to do..
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_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();
decodeFile(picturePath);
}
}

Use the below code for opening in the image gallery.
Intent browseIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(browseIntent, RESULT_LOAD_IMAGE);
and below code for pick the image from gallery.
#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) {

cursor.close();
try {
byte[] b;
Log.d("picture", imagePath);
bm = BitmapFactory.decodeFile(imagePath);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
b = baos.toByteArray();

Instead of trying it by yourself, take a look at recent-images library. It can help you. here is the link.

Here is the complete code. But still getting error on cursor. In besides, here used contentResolver query stuff.What I think I should add some extra code for that.Can someone tell me about contentResolver and my problem
Try this...
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
this my code its not working how pick up image from gallery and display in imageview
public class MainActivity extends ActionBarActivity {
Button imageUpload;
ImageView imageView;
static final int PICTURE = 1;
#Override

super.onCreate(savedInstanceState);

hello friends i am new in android i required this type of apps to upload image and display in imageview plz help me if have idea.thanks in advance
Finnay this Code is working and we can give fixed size of imageview that display in particular area
layout.xml
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Image Upload"
android:id="#+id/buttonImage"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/imageView"
android:layout_x="13dp"
android:layout_y="112dp" />
Main Activity
Button imageUpload;
ImageView imageView;
static final int PICTURE = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView= (ImageView) findViewById(R.id.imageView);
imageUpload= (Button) findViewById(R.id.buttonImage);
imageUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent,PICTURE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode==PICTURE && resultCode==RESULT_OK && null !=data)
{
Uri uri = data.getData();

Cursor cursor=getContentResolver().query(uri,prjection,null,null,null);
cursor.moveToFirst();
int columnIndex=cursor.getColumnIndex(prjection[0]);
String path=cursor.getString(columnIndex);
cursor.close();
Bitmap selectFile = BitmapFactory.decodeFile(path);
Drawable d = new BitmapDrawable(selectFile);
imageView.setBackground(d);
// imageView.setImageBitmap(BitmapFactory.decodeFile(path));
}
}
Finally this code is working
Replace
Bitmap selectFile = BitmapFactory.decodeFile(path);
Drawable d = new BitmapDrawable(selectFile);
imageView.setBackground(d);
To
imageView = (ImageView) findViewById(R.id.imageView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
use this code

Also, in onActivityResult, the switch and if statements are both checking for requestCode. Therefore the if is never true.
Replace
if(requestCode==RESULT_OK)
with
if(resultCode==RESULT_OK)
I'm trying to:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, RESULTADO_GALERIA);
.
.
.
String imgPath = data.getDataString(); // return something like "/external/images/media/13852"
BitmapFactory.decodeFile(imgPath); // allways null...
I also tried:
File bitmapFile = new File(Environment.getExternalStorageDirectory()
+ "/" + imgPath);
String aux = bitmapFile.getAbsolutePath(); // /storage/sdcard0/external/images/media/13852
BitmapFactory.decodeFile(bitmapFile.getAbsolutePath()); // NULL
An the result it's the same
The olny thing work's for me is put the path manually...
File file = new File("/storage/sdcard0/DCIM/Camera/"+"IMG_20140506_101341.jpg"); // nothing to do with the path obtained by code...
BitmapFactory.decodeFile(bitmapFile.getAbsolutePath()); // OK
How can I get the REAL path for a image of the gallery? Other ideas to resize them?
Thanks!

I want to get an image from a gallery to show in imageview. Intent returned the path as "Content" in Sony mobile. I can get it using this code.
Uri image=data.getData();
But when I am using a Samsung mobile, intent returned this.
Intent { act=file:///mnt/sdcard/Pictures/Education%20App/IMG_20140513_160840.jpg (has extras) }
I used same code to get the URI, but the returned value is null. I don't know how to get this Uri.

I use below code to start camera capture on a button clicked:
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(captureIntent, Variables.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
On activity result, I just simply start "crop" activity.
if (requestCode == Variables.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
picUri = data.getData();
performCrop();
}
When the camera first started, I pressed the back button to go back to the caller activity (A.class). And then start another activity, say B.class, causes window leak. Sometimes when B.class is called, the screen keep flashing....What's wrong with the code? Please HELP! Many thanks.
There are some alert dialogs I created, but it is already dismissed.
Try this is working like charm with me
private String selectedImagePath = "";
final private int PICK_IMAGE = 1;
final private int CAPTURE_IMAGE = 2;
public Uri setImageUri() {
// Store image in dcim
File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".png");
Uri imgUri = Uri.fromFile(file);
this.imgPath = file.getAbsolutePath();
return imgUri;
}
public String getImagePath() {
return imgPath;
}
btnGallery.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);
}
});
btnCapture.setOnClickListener(new OnClickListener() {
#Override

intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri());
startActivityForResult(intent, CAPTURE_IMAGE);
}
});

} else if (requestCode == CAPTURE_IMAGE) {

} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
