Android onActivityResult deprecated

改用registerForActivityResult

寫一個ActivityResultLauncher<Intent> askforResult物件

ActivityResultLauncher<Intent> askforResult = registerForActivityResult(
        new ActivityResultContracts.StartActivityForResult(),
        new ActivityResultCallback<ActivityResult>(){

            @Override
            public void onActivityResult(ActivityResult result) {
                if (result.getResultCode() == Activity.RESULT_OK){
                    Intent it = result.getData();
                    Uri uri = it.getData();
                    Log.d(TAG, uri.toString());
                }
            }
        }
);

呼叫時改用

Intent it = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
askforResult.launch(it);
