The code below can be used for taking a photo and for picking a photo. Just show a dialog with two options and upon selection, use the appropriate code.
To take picture from camera:
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);//zero can be replaced with any action code (called requestCode)
To pick photo from gallery:
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);//one can be replaced with any action code
onActivityResult code:
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 0:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
case 1:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
}
}
Finally add this permission in the manifest file:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
I have merged some solutions to make a complete util for picking an image from Gallery or Camera. These are the features of ImagePicker util gist (also in a Github lib):
Screenshot:
Edit: Here is a fragment of code to get a merged Intent for Gallery and Camera apps together. You can see the full code at ImagePicker util gist (also in a Github lib):
public static Intent getPickImageIntent(Context context) {
Intent chooserIntent = null;
List<Intent> intentList = new ArrayList<>();
Intent pickIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePhotoIntent.putExtra("return-data", true);
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(context)));
intentList = addIntentsToList(context, intentList, pickIntent);
intentList = addIntentsToList(context, intentList, takePhotoIntent);
if (intentList.size() > 0) {
chooserIntent = Intent.createChooser(intentList.remove(intentList.size() - 1),
context.getString(R.string.pick_image_intent_text));
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new Parcelable[]{}));
}
return chooserIntent;
}
private static List<Intent> addIntentsToList(Context context, List<Intent> list, Intent intent) {
List<ResolveInfo> resInfo = context.getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : resInfo) {
String packageName = resolveInfo.activityInfo.packageName;
Intent targetedIntent = new Intent(intent);
targetedIntent.setPackage(packageName);
list.add(targetedIntent);
}
return list;
}
This library makes it simple.
Just Call:
PickImageDialog.on(MainActivity.this, new PickSetup(BuildConfig.APPLICATION_ID));
Then make your Activity implement IPickResult and override this below method.
@Override
public void onPickResult(PickResult r) {
if (r.getError() == null) {
imageView.setImageBitmap(r.getBitmap());
//or
imageView.setImageURI(r.getUri());
} else {
//Handle possible errors
//TODO: do what you have to do with r.getError();
}
}
You can implement this code to select image from gallery or camera :-
private ImageView imageview;
private Button btnSelectImage;
private Bitmap bitmap;
private File destination = null;
private InputStream inputStreamImg;
private String imgPath = null;
private final int PICK_IMAGE_CAMERA = 1, PICK_IMAGE_GALLERY = 2;
Now on button click event, you can able to call your method of select Image. This is inside activity's onCreate.
imageview = (ImageView) findViewById(R.id.imageview);
btnSelectImage = (Button) findViewById(R.id.btnSelectImage);
//OnbtnSelectImage click event...
btnSelectImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
selectImage();
}
});
Outside of your activity's oncreate.
// Select image from camera and gallery
private void selectImage() {
try {
PackageManager pm = getPackageManager();
int hasPerm = pm.checkPermission(Manifest.permission.CAMERA, getPackageName());
if (hasPerm == PackageManager.PERMISSION_GRANTED) {
final CharSequence[] options = {"Take Photo", "Choose From Gallery","Cancel"};
android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(activity);
builder.setTitle("Select Option");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
dialog.dismiss();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_IMAGE_CAMERA);
} else if (options[item].equals("Choose From Gallery")) {
dialog.dismiss();
Intent pickPhoto = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto, PICK_IMAGE_GALLERY);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
} else
Toast.makeText(this, "Camera Permission error", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(this, "Camera Permission error", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
inputStreamImg = null;
if (requestCode == PICK_IMAGE_CAMERA) {
try {
Uri selectedImage = data.getData();
bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, bytes);
Log.e("Activity", "Pick from Camera::>>> ");
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
destination = new File(Environment.getExternalStorageDirectory() + "/" +
getString(R.string.app_name), "IMG_" + timeStamp + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
imgPath = destination.getAbsolutePath();
imageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == PICK_IMAGE_GALLERY) {
Uri selectedImage = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, bytes);
Log.e("Activity", "Pick from Gallery::>>> ");
imgPath = getRealPathFromURI(selectedImage);
destination = new File(imgPath.toString());
imageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}
}
public String getRealPathFromURI(Uri contentUri) {
String[] proj = {MediaStore.Audio.Media.DATA};
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Atlast, finally add the camera and write external storage permission to AndroidManifest.xml
It works for me greatly, hope it will also works for you.
If you want to get the image from gallery or capture the image and set it to the imageview in portrait mode then following code will help you..

Hope This will help you....!!!
If targetSdkVersion is higher than 24, then FileProvider is used to grant access.
Create an xml file(Path: res\xml) provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Add a Provider in AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
and replace
return Uri.fromFile(getOutputMediaFile(type));
To
return FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", getOutputMediaFile(type));
