如何将微调器值传递给IBM api中的目标语言？

Question

我有一个由IBM库中的语言组成的微调器。我希望用户选择一种语言，然后将文本翻译成所选的语言。我从微调器中获得了价值，但我不知道如何将价值传递给目标语言。请帮助。

`enter code here`Spinner s = (Spinner) findViewById(R.id.spinner1);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, languages);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    s.setAdapter(adapter);
    text = s.getSelectedItem().toString(); // value from spinner



    new Hey().execute();
}


    class Hey extends AsyncTask<Void, Void, String> {
    String text;


        protected void onPreExecute() {
            super.onPreExecute();

        }


        @Override
        protected String doInBackground(Void... voids) {

            IamAuthenticator authenticator = new IamAuthenticator("nAh_Z_0X2AS1Vun2MI3UR3lYNRivFRkWaNsZyFwELMul"); //key
            LanguageTranslator languageTranslator = new LanguageTranslator("2018-05-01", authenticator);
            languageTranslator.setServiceUrl("https://api.eu-gb.language-translator.watson.cloud.ibm.com/instances/83f66689-1c94-4a9b-b595-e2d776f10ded"); //url

            TranslateOptions translateOptions = new TranslateOptions.Builder()
                    .addText("Hello")
                    .source(Language.ENGLISH)
                    .target(Language.SPANISH) // need to get user to select the target language from the spinner option
                    .build();

            TranslationResult result = languageTranslator.translate(translateOptions) //translation happens
                    .execute().getResult();

            String som = result.toString();
            System.out.println(som);


            return som;
        }

首先，您需要了解如何将值作为参数传递给AsyncTask。因此，从微调器中获取值后，将其传递给AsyncTask参数。您的代码将如下所示-

text = s.getSelectedItem().toString(); // value from spinner
new Hey().execute(text);

现在在AsyncTask中，您将确定传递的参数-

 class Hey extends AsyncTask<Void, Void, String> {
    String text;

        @Override
        protected String doInBackground(Void... voids) {

       String language = (String) params[0]; //can use it further
}
}
