Ich bin neu, um native zu reagieren. Während ich ein nationales Modul entwickelte, stoße ich auf ein Problem mit Rückrufen.

< /code>

und mein natives Modul sehen so aus < /p>

@ReactMethod
public void testCallback(String message, Callback c1, Callback c2, Callback c3) {
if (message.equals("123")) {
c1.invoke(message);
} else if (message.equals("abc")) {
c2.invoke(message);
} else {
c3.invoke(message);
}
}
< /code>

und meine Aufruffunktion von React < /p>

onBtnPress() {

function f1 () {
ToastExample.show('1111', ToastExample.SHORT);
};

function f2 () {
ToastExample.show('2222', ToastExample.SHORT);
};

function f3 () {
ToastExample.show('3333', ToastExample.SHORT);
};

ToastExample.testCallback('abc', f1, f2, f3);
}
< /code>

Ich habe keine Ahnung, warum dieser Fehler passiert. Kann mir jemand helfen? Danke.
