android - onActivityResult 未在 fragment 中调用

Question

fragment 中的代码

 private static final int BRAINTREE_REQUEST_CODE = 777;
    BottomMenu fragment = this;
    public void onBraintreeSubmit(String clienTtoken) {
        DropInRequest dropInRequest = new DropInRequest().clientToken(clienTtoken);
        startActivityForResult(dropInRequest.getIntent(getActivity()), BRAINTREE_REQUEST_CODE);
    }
@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == BRAINTREE_REQUEST_CODE) {
            if (resultCode == Activity.RESULT_OK) {
                DropInResult result = data.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT);
                Toast.makeText(getActivity(), result.getPaymentMethodNonce().getNonce() + "", Toast.LENGTH_SHORT).show();
                // use the result to update your UI and send the payment method nonce to your server
                sendPaymentNonceToServer(result.getPaymentMethodNonce().getNonce());
            } else if (resultCode == Activity.RESULT_CANCELED) {
                // the user canceled
            } else {
                // handle errors here, an exception may be available in
                Exception error = (Exception) data.getSerializableExtra(DropInActivity.EXTRA_ERROR);
            }
        }
    }

Activity 代码

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
    }

问题:

I have implemented BrainTree payment gateway with onBraintreeSubmit() method I startActivityResult and catch it onActivityResult but it's not being called in the fragment.

onActivityResult only gets called if I cancel payment but never when payment success or exception thrown

Answer 1

First you have to call from activity Add below code in your activity

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.frameLayout);
    fragment.onActivityResult(requestCode, resultCode, data);

}
