从onPostExecute返回字符串

Posted 2021-05-02

我用asynctask从json中捕获一个字符串。我想将catched string发送到另一个类来插入数据库。

TranslatedWord trWord=new TranslatedWord();

@Override
protected void onPostExecute(JSONObject json) {
    try {
        JSONArray result = json.getJSONArray(TAG_RESULTS);
        String text = result.getString(0); //Catched string here

        trWord.setTranslatedWord(text);
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

我创建了一个新类来保持字符串。但我失败了

public class TranslatedWord {
    private String trWord;

    public void setTranslatedWord(String trWord) {
        this.trWord = trWord;
    }

    public String getTrWord() {
        return trWord;
    }

    public void setTrWord(String trWord) {
        this.trWord = trWord;
    }
}

我用这段代码调用字符串

String translatedWord = trWord.getTrWord();

我哪里做错了？

答案

    public class TranslatedWord {

    private static String trWord;

    public String getTrWord() {
        return trWord;
    }

    public void setTrWord(String trWord) {
        this.trWord = trWord;
    }
}

我刚做了变量静态。它的运行。
