Question

片段中的代码

 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);
            }
        }
    }

活动代码

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

问题：

我已经使用onBraintreeSubmit（）方法实现了BrainTree支付网关我使用startActivityResult并将其捕获到onActivityResult但是它没有在片段中被调用。

onActivityResult仅在我取消付款时被调用，但从未在付款成功或抛出异常时被调用

Answer 1

首先你需要从活动中打电话在您的活动中添加以下代码

 @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);

}

Answer 2

如果使用活动实例调用startActivityForResult（），则onActivityResult将进入您的活动而不是片段。这就是你问题的原因。

修改代码如下。这将解决您的问题。

public void onBraintreeSubmit(String clienTtoken, BottomMenu context) {
    DropInRequest dropInRequest = new DropInRequest().clientToken(clienTtoken);
    startActivityForResult(dropInRequest.getIntent(context.getContext()), BRAINTREE_REQUEST_CODE);
}

onActivityResult未在片段中调用
