android - 打开 Instagram 用户资料

Question

我设法从我的应用程序中打开了 Twitter 和 Facebook 用户个人资料。但我找不到对 Instagram 的任何引用。

有没有办法打开 Instagram 以便在 twitter 或 facebook 中显示用户个人资料？

例如，为了获得 Intent 来启动 twitter 应用程序，我这样做:

public Intent getOpenTwitterIntent(Context context) {

    try {
        return new Intent(Intent.ACTION_VIEW,
                Uri.parse("twitter://user?screen_name="
                        .concat(twitterUsername)));

    } catch (Exception e) {
        return new Intent(
                Intent.ACTION_VIEW,
                Uri.parse("https://twitter.com/#!/".concat(twitterUsername)));
    }

}

如何使用 Instagram 实现类似的效果？提前致谢。

这是一种获取 Intent 以打开 Instagram 应用程序到用户个人资料页面的方法:

/**
 * Intent to open the official Instagram app to the user's profile. If the Instagram app is not
 * installed then the Web Browser will be used.</p>
 * 
 * Example usage:</p> {@code newInstagramProfileIntent(context.getPackageManager(), 
 *     "http://instagram.com/jaredrummler");}</p>
 * 
 * @param pm
 *            The {@link PackageManager}. You can find this class through
 *            {@link Context#getPackageManager()}.
 * @param url
 *            The URL to the user's Instagram profile.
 * @return The intent to open the Instagram app to the user's profile.
 */
public static Intent newInstagramProfileIntent(PackageManager pm, String url) {
    final Intent intent = new Intent(Intent.ACTION_VIEW);
    try {
        if (pm.getPackageInfo("com.instagram.android", 0) != null) {
            if (url.endsWith("/")) {
                url = url.substring(0, url.length() - 1);
            }
            final String username = url.substring(url.lastIndexOf("/") + 1);
            // http://stackoverflow.com/questions/21505941/intent-to-open-instagram-user-profile-on-android
            intent.setData(Uri.parse("http://instagram.com/_u/" + username));
            intent.setPackage("com.instagram.android");
            return intent;
        }
    } catch (NameNotFoundException ignored) {
    }
    intent.setData(Uri.parse(url));
    return intent;
}
