Android get image from gallery into ImageView
Solution 1
Run the app in debug mode and set a breakpoint on if (requestCode == SELECT_PICTURE)
and inspect each variable as you step through to ensure it is being set as expected. If you are getting a NPE on img.setImageURI(selectedImageUri);
then either img
or selectedImageUri
are not set.
Solution 2
Simple pass Intent
first:
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
And you will get picture path on your 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();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}

@parag's code works great. But while loading some large images you may fail. You should use;
imageView.setImageBitmap(getScaledBitmap(picturePath, 800, 800));
instead of;
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
Here are my methods that you can use.
private Bitmap getScaledBitmap(String picturePath, int width, int height) {
BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
sizeOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(picturePath, sizeOptions);
int inSampleSize = calculateInSampleSize(sizeOptions, width, height);
sizeOptions.inJustDecodeBounds = false;
sizeOptions.inSampleSize = inSampleSize;
return BitmapFactory.decodeFile(picturePath, sizeOptions);
}
private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
// Calculate ratios of height and width to requested height and
// width
final int heightRatio = Math.round((float) height / (float) reqHeight);
final int widthRatio = Math.round((float) width / (float) reqWidth);
// Choose the smallest ratio as inSampleSize value, this will
// guarantee
// a final image with both dimensions larger than or equal to the
// requested height and width.
inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
}
return inSampleSize;
}

This is the easiest way to get image from gallery and crop ass well
step 1: StartActivity for result
imageUser.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.INTERNAL_CONTENT_URI);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("scale", true);
intent.putExtra("outputX", 256);
intent.putExtra("outputY", 256);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("return-data", true);
startActivityForResult(intent, 1);
}
});
step 2:Handle the result
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == 1) {
final Bundle extras = data.getExtras();
if (extras != null) {
//Get image
Bitmap ProfilePic = extras.getParcelable("data");
imageUser.setImageBitmap(ProfilePic);
TextView t=(TextView)findViewById(R.id.textoverimage);
t.setText("image Selected");
}
}
}

Admin about 3 years
I'm trying to add a photo from galery to a
ImageView
but I get this error:java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://media/external/images/media/1 }} to activity {hotMetter.pack/hotMetter.pack.GetPhoto}: java.lang.NullPointerException
This is my code:
Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE); } Bitmap bitmap=null; public void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == Activity.RESULT_OK) { if (requestCode == SELECT_PICTURE) { Uri selectedImageUri = data.getData(); selectedImagePath = getPath(selectedImageUri); tv.setText(selectedImagePath); img.setImageURI(selectedImageUri); } } public String getPath(Uri uri) { String[] projection = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(uri, projection, null, null, null); if (cursor == null) return null; int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); String s=cursor.getString(column_index); cursor.close(); return s; }
I get the
selectedImagePath="mnt/sdcard/DCIM/myimage"
but onimg.setImageURI(selectedImageUri);
i get the error.I've also used a
Bitmap
and tried to set the image fromSetImageBitmap
but i get the same error.LogCat:

Advice please.Thanks!

mbrenon over 10 yearsThe pictures taken by the camera are always stored in landscape mode, only an orientation flag is stored in the file. This answer seems to provide a viable solution!
-
Krystian almost 10 yearsThere coud be some exceptions (not java exceptions ;) ) - .query method for URI gets proper data, only when intent contains data starting with dat=content://... I have one files explorer application which returns dat="file:///... - I can't find good solution for that...

Horatio almost 9 yearsIf import android.provider.MediaStore is imported, you can write "MediaStore.Images.Media.EXTERNAL_CONTENT_URI" rather than "android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI"

Gopalakrishna Umapathi almost 7 years@Solo "RESULT_LOAD_IMAGE" is a request code, it is an "int" can assign numbers to it. The below link can be helpful to you.link. And sorry for the delay in response.
