下面的代码显示一个AlertDialog，该对话框收集信用卡数据，即号码，有效性和CVC，以使用Stripe付款。有了这些数据，stripe.createToken函数（...）应该向TokenCallback（）返回一个令牌。问题是，即使使用正确的卡数据（大约五分之一），也不会提取令牌，并且不会返回错误。
private void dialogRenewWithStripe() {
final ViewGroup nullParent = null;
View view = getLayoutInflater().inflate(R.layout.dialog_container_renew_stripe, nullParent, false);
...
CardMultilineWidget mCardMultilineWidget = view.findViewById(R.id.add_source_card_entry_widget);
AlertDialog.Builder builder = dialogBuilder2(mContext);
builder.setView(view);
builder.setIcon(R.drawable.ic_pay);
builder.setCancelable(false);
builder.setTitle(getResources().getString(R.string.msg0333));
builder.setNegativeButton("CANCEL", (dialogInterface, i) -> { });
builder.setPositiveButton("CONFIRM", (dialogInterface, i) -> { });
alertDialog2 = builder.create();
alertDialog2.setOnShowListener(dialogInterface -> {
((AlertDialog)dialogInterface).getButton(AlertDialog.BUTTON_NEGATIVE).setOnClickListener(v -> {
btnRenew.setImageAlpha(255);
btnRenew.setEnabled(true);
alertDialog2.dismiss();
});
((AlertDialog)dialogInterface).getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(v -> {
if (mCardMultilineWidget.getCard() != null) {
alertDialog2.dismiss();
dialogWhait( getResources().getString(R.string.msg0251) );
Stripe stripe = new Stripe(mContext, "pk_test_XXXXXXXXXXXXXXXXXXXX");
stripe.createToken(
mCardMultilineWidget.getCard(),
new TokenCallback() {
public void onSuccess(Token token) {
alertDialogWhaiting.dismiss();
dialogWhait( getResources().getString(R.string.msg0330) );

我将StripePaymentDialog＃createStripeToken中的嵌入式匿名TokenCallback类移动为实例变量（请参见下文），问题似乎消失了。我相信匿名类在内联时会被垃圾回收。
public class StripePaymentDialog extends DialogFragment {
@NonNull private final TokenCallback mTokenCallback = new TokenCallback() {
@Override
public void onSuccess(Token token) {
Log.d("Stripe Token Success: ", token.toString());
setSubmitSuccess(token.getId());
}
@Override
public void onError(Exception error) {
if (error != null && error.getMessage().length() > 0) {
Log.d("Stripe Token Error: ", error.getLocalizedMessage());
setErrorMessage(error.getLocalizedMessage());
setSubmitError();
}
}
};
private void createStripeToken() {
mStripe.createToken(mCard, mDefaultPublishKey, mTokenCallback);
}
}
