如何显示JSON到TextViews

Question

我正在尝试向文本视图显示一些JSON数据。我的" getTitle" getter方法正常工作，并且数据显示在文本视图小部件中。但是，当我应该通过" GetDescription" Getter方法时，建议并不提出建议。我真的很喜欢这方面的帮助，或者如果我不这样做的话，有人可以将我指向正确的方向。

    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活动模型类。我还认为，重要的是要提及我的" getDescription" getter和setter以淡灰色颜色显示，而" getTitle" getter和setter是金色的颜色。感谢您提前的帮助。

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

尝试下面，您正在呼叫响应

上调用方法

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

Answer 2

响应的主体将保留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，您必须使用响应的主体，例如响应。Body（）。getDescription（），响应。Body.body（）。getCreated（）。要在文本视图中显示描述，请尝试以下

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