Simplified abstraction over Android Image Cropper library to pick images from gallery or camera and crop them if needed.
Add this line to build.gradle
compile 'com.myhexaville:smart-image-picker:1.0'imagePicker = new ImagePicker(this, /* activity non null*/
null, /* fragment nullable*/
imageUri -> {/*on image picked */
imageView.setImageURI(imageUri);
})
.setWithImageCrop(
1 /*aspect ratio x*/
1 /*aspect ratio y*/);Override Activity's methods to delegate permissions to ImagePicker and resulting image
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
imagePicker.handleActivityResult(resultCode,requestCode, data);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
imagePicker.handlePermission(requestCode, grantResults);
}There's two methods available
imagePicker.openCamera();
imagePIcker.choosePicture(true /*show camera intents*/);First one opens camera directly, second shows an intent picker, where user picks from desired application. You can include/exclude camera intents with boolean.
That's it, if you don't need to crop image, don't call setImageCrop() in the chain. By default it's disabled. And if you want to get a file after you picked image, you can get it with this method
File file = imagePicker.getImageFiel();Create instance
imagePicker = new ImagePicker(getActivity(),
this,
imageUri -> {/*on image picked */
imageView.setImageURI(imageUri);
})
.setWithImageCrop(
1 /*aspect ratio x*/
1 /*aspect ratio y*/);Overriden methods should be in your Fragment
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
imagePicker.handleActivityResult(resultCode, requestCode, data);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
imagePicker.handlePermission(requestCode, grantResults);
}But your fragment won't get activity result callback itself. You need to call it manually. Add this code to activity that hosts your fragment
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
List<Fragment> fragments = getSupportFragmentManager().getFragments();
if (fragments != null) {
for (Fragment f : fragments) {
if (f instanceof YourFragment) {
f.onActivityResult(requestCode, resultCode, data);
}
}
}
}
