Question

我谨通过<代码>使用意图.setData(Uri uri)通过从URL获得的数据。为此,我需要能够从URL(或从旁听)中建立一个Uri。页: 1 ByteArrayInputStream 页: 1 然而,我无法说明应如何做到这一点。

So, is there anyway to create a Uri from data obtained from a URL without first writing the data to a local file?

Answer 1

http://docs.oracle.com/javase/6/docs/api/java/net/URL.html#toURI%2829”rel=“noreferer”>URL.toURI()(。

例:

URL url = new URL("http://www.google.com"); //Some instantiated URL object
URI uri = url.toURI();

I think your answer can be found from here..

Uri.Builder.build(> 运行良好,正常的URLs运行良好,但未能得到港口号码支持。

我发现最容易地使其支持港口号码,就是让港口停泊,先与港口局合作。

Uri.Builder b = Uri.parse("http://www.yoursite.com:12345").buildUpon();

b.path("/path/to/something/");
b.appendQueryParameter("arg1", String.valueOf(42));

if (username != "") {
  b.appendQueryParameter("username", username);
}

String url = b.build().toString();

Answer 4

注:在安内斯,Uri s与Java URI s不同。在这里,如何避免使用硬编码拼法,同时,创建一条Uri,其途径部分仅包括http URL string encoded to RFC2396:

Sample Url String:

String thisUrl = "http://lapi.transitchicago.com/api/1.0/ttarrivals.aspx?key=[redacted]&mapid=value"

方法:

private Uri.Builder builder;
public Uri getUriFromUrl(String thisUrl) {
    URL url = new URL(thisUrl);
    builder =  new Uri.Builder()
                            .scheme(url.getProtocol())
                            .authority(url.getAuthority())
                            .appendPath(url.getPath());
    return builder.build();
}

为了处理询问,你需要将所描述的“url.get Query”(,,然后将这些资料输入建筑商。附录。

try {
    uri = new URI(url.toString());
} catch (URISyntaxException e) {
}
