Question

我正在尝试向textviews显示一些json数据。我的“getTitle”getter方法工作正常，数据显示在textview小部件中。但是，当我应该通过“getDescription”getter方法时，它不会出现建议。我真的很喜欢这方面的一些帮助，或者如果我没有按照正确的方式指出我正确的方向。

    call.enqueue(new Callback<Campaign>() {
        @Override
        public void onResponse(Call<Campaign> call, Response<Campaign> response) {

            if (response.isSuccessful()) {
                String id = response.body().getId();
                campaignName.setText(getTitle());
                campaignDesc.setText();


            } else {
                Toast.makeText(StartSurveyActivity.this, "Error Retrieving Id", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<Campaign> call, Throwable t) {
            // Log error here if request failed
            Log.e(TAG, t.toString());
        }
    });
}

这是我的java广告系列模型类。另外我认为重要的是要提到我的“getDescription”getter和setter以浅灰色显示，而“getTitle”getter和setter则是金色的颜色。感谢您的帮助。

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getQuestion() {
    return question;
}

public void setQuestion(String question) {
    this.question = question;
}

public Boolean getDeleted() {
    return deleted;
}

public void setDeleted(Boolean deleted) {
    this.deleted = deleted;
}

public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}

public String getSurveyUrl() {
    return surveyUrl;
}

public void setSurveyUrl(String surveyUrl) {
    this.surveyUrl = surveyUrl;
}

public Integer getTotalResponseCount() {
    return totalResponseCount;
}

public void setTotalResponseCount(Integer totalResponseCount) {
    this.totalResponseCount = totalResponseCount;
}

public String getLanguageCode() {
    return languageCode;
}

public void setLanguageCode(String languageCode) {
    this.languageCode = languageCode;
}
public List<Question> getQuestions() {
    return questions;
}

public void setQuestions(List<Question> questions) {
    this.questions = questions;
}

public Date getCreated() {
    return created;
}

public void setCreated(Date created) {
    this.created = created;
}

public String getOrganisationLogoUrl() {
    return organisationLogoUrl;
}

public void setOrganisationLogoUrl(String organisationLogoUrl) {
    this.organisationLogoUrl = organisationLogoUrl;
}

public String getOrganisationName() {
    return organisationName;
}

public void setOrganisationName(String organisationName) {
    this.organisationName = organisationName;
}

Answer 1

请尝试以下操作，您正在调用方法

campaignName.setText(response.body().getDescription())

Answer 2

响应正文将保存您定义的数据或响应对象。因此，要调用响应对象的任何getter或setter方法，必须使用响应的主体，例如response.body（）。getDescription（），response.body（）。getCreated（）。要在TextView中显示说明，请尝试使用

campaignDesc.setText(response.body().getDescription())

如何将json显示到textviews？
