final SpannableString s = new SpannableString(
Html.fromHtml("<br><a href=\"http://google.com\">a new link</a>")
);
final TextView tx1 = new TextView(this);
tx1.setText(getString(R.string.librarytextpart1)
+ s
+ getString(R.string.librarytextpart2));
tx1.setAutoLinkMask(RESULT_OK);
tx1.setMovementMethod(LinkMovementMethod.getInstance());
Linkify.addLinks(s, Linkify.ALL);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(getString(R.string.library))
.setCancelable(false)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
}
})
.setView(tx1).show();
当单击对话框中的 SpannableString 文本时，它显示整个文本都是可单击的......并且仍然无法打开网页。当然，我不明白文档中的某些内容，但不明白是什么。你能帮忙吗？

我在原生Android中使用facebook sdk 3.5.这就是我获取我的facebook朋友的id /名字的方式:
private void onSessionStateChange(final Session session,
SessionState state, Exception exception) {
System.out.println("onSessionStateChanged");
if (session != null && session.isOpened()) {
if (state.equals(SessionState.OPENED_TOKEN_UPDATED)) {
tokenUpdated();
} else {
getUserRequest(session);
getFriendsRequest(session);
}
} else {
profilePictureView.setProfileId(null);
userNameView.setText("");
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(getActivity(), requestCode,
resultCode, data);
// uiHelper.onActivityResult(requestCode, resultCode, data,
// nativeDialogCallback);
}
private void getFriendsRequest(Session session) {
session.requestNewReadPermissions(new NewPermissionsRequest(
getActivity(), PERMISSIONS));
final ProgressDialog dialog = new ProgressDialog(getActivity());
