当我尝试使用毕加索显示图像时，我需要传递标题.

I need to pass a header when I try to show a image using Picasso.

任何人都可以建议在查看图像时如何向毕加索添加页眉.

Can any one suggest how to add header to picasso while viewing the image.

推荐答案

您可以为此使用downloader:

示例:

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {
                Request newRequest = chain.request().newBuilder()
                        .addHeader("custom-header", "custom-header-value")
                        .build();
                return chain.proceed(newRequest);
            }
        })
        .build();

Picasso picasso = new Picasso.Builder(context)
        .downloader(new OkHttp3Downloader(client))
        .build();

请记住，如果您已经在使用OkHttpClient，则应该使用该实例或使用client.newBuilder()创建一个新实例.这样，两个实例将使用相同的请求队列.

Keep in mind that if you are using OkHttpClient already, you should use that instance or create new one using client.newBuilder(). This way, both instances will be using the same request queue.
