Crop with 1:1 aspect ratio
Start image picker activity
The simplest way to start is setup options and start the activity. Set the FLAG_CROP to crop resulting image in 1:1 aspect ratio
Intent intent = new Intent(this, ImageSelectActivity.class);
intent.putExtra(ImageSelectActivity.FLAG_COMPRESS, false);//default is true
intent.putExtra(ImageSelectActivity.FLAG_CAMERA, true);//default is true
intent.putExtra(ImageSelectActivity.FLAG_GALLERY, true);//default is true
intent.putExtra(ImageSelectActivity.FLAG_CROP, isCrop);//default is false
startActivityForResult(intent, 1213);Receive result
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1213 && resultCode == Activity.RESULT_OK) {
String filePath = data.getStringExtra(ImageSelectActivity.RESULT_FILE_PATH);
Bitmap selectedImage = BitmapFactory.decodeFile(filePath);
imageView.setImageBitmap(selectedImage);
}
