我需要将一个范围内的值绘制为黄色,将其他范围绘制为红色.怎么实现呢？

我正在从服务器获取该响应：

{
    "auth_token": "062450b9dd7e189f43427fbc5386f7771ba59467"
}

为了访问它，我需要使用与原始 JSON 中相同的名称。

[System.Serializable]
public class TokenResponse
{
    public string auth_token; // I want to rename it to authToken without renaming corresponding field in json
    public static TokenResponse CreateFromJSON(string json) {
        return JsonUtility.FromJson<TokenResponse>(json);
    }
}

如何将 TokenResponse.auth_token 重命名为 TokenResponse.authToken 而不丢失功能？

通过使用以下代码进行改造，我成功地将图像上传到了我的REST API：

        File imageFile = ImagePicker.getFileFromResult(this, resultCode, data);
        RequestBody requestFile =
                RequestBody.create(MediaType.parse("multipart/form-data"), imageFile);
        MultipartBody.Part body =
                MultipartBody.Part.createFormData("userpic", imageFile.getName(), requestFile);

        RetrofitClient.compositeSubscription.add(RetrofitClient.getService().updateProfileUserpic("Token " + RevolutionApp.getInstance().getUserToken(), body).subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<Profile>() {
                    @Override
                    public void onCompleted() { }

                    @Override
                    public void onError(Throwable e) { }

                    @Override
                    public void onNext(Profile profile) {
                        mProfileFragment.fetchProfileData();
                    }
                }));

现在，我需要向我的API发送空文件（空）。如何执行呢？

MultipartBody.Part.createFormData("userpic", imageFile.getName(), requestFile)

不起作用

我需要启用放置在nestescrollview中的viewpager的webview滚动,因为我正在使用CollapsingToolbarLayout.但我不能滚动它.所有工作除了WebView滚动.哪里错了？

这是我的活动标记:

ViewPager标记的WebView片段:

    android:layout_height="match_parent"
    android:layout_marginTop="8dp"

Java代码：

String imagesArrayResponse = xmlNode.getChildText("files");
Matcher m = Pattern.compile("path\":\"([^\"]*)").matcher(imagesArrayResponse);

while (m.find()) {
    String path = m.group(0);
}

串：

[{"path":"upload\/files\/56727570aaa08922_0.png","dir":"files","name":"56727570aaa08922_0","original_name":"56727570aaa08922_0.png"}{"path":"upload\/files\/56727570aaa08922_0.png","dir":"files","name":"56727570aaa08922_0","original_name":"56727570aaa08922_0.png"}{"path":"upload\/files\/56727570aaa08922_0.png","dir":"files","name":"56727570aaa08922_0","original_name":"56727570aaa08922_0.png"}{"path":"upload\/files\/56727570aaa08922_0.png","dir":"files","name":"56727570aaa08922_0","original_name":"56727570aaa08922_0.png"}]

m.group退货

path":"upload\/files\/56727570aaa08922_0.png"

而不是路径的捕获​​值。我哪里错了？
