我正在尝试打开用户的Facebook个人资料页面，如图here所示。在我的应用程序中，用户在授予我的应用程序权限后登录，并获得FB ID，姓名，电子邮件等常用详细信息。但我无法使用FB ID在浏览器中打开配置文件页面。有没有其他方式来显示个人资料页面？
public class MainActivity extends AppCompatActivity {
CallbackManager callbackManager;
AccessTokenTracker accessTokenTracker;
AccessToken accessToken;
String fbid;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FacebookSdk.sdkInitialize(getApplicationContext());
facebookOncreateCalling();
Button loginbtn = (Button) findViewById(R.id.loginbtn);
loginbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
LoginManager.getInstance().logOut();
} catch (Exception e) {
e.printStackTrace();
}
LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("public_profile", "user_friends", "email", "user_birthday", "user_about_me"));
}
});
// Here I want to open facebook profile page in browser
Button openWeb = (Button)findViewById(R.id.openWeb);
openWeb.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
/*Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
//String facebookUrl = "http://www.facebook.com/"+fbid;

您将通过以下陈述获得名称 loginusername = response.getString（＆＃34; name＆＃34;）;
LoginManager.getInstance().registerCallback(callbackmanager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {
JSONObject response = graphResponse.getJSONObject();
Log.e(LoginActivity.class.getSimpleName(), "response data is" + response.toString());
try {
if (response.has("email")) {
login_userid = response.getString("id");
**loginusername = response.getString("name");**
login_user_email = response.getString("email");
profileUpdate.put("Login", "Facebook Login success");
cleverTap.event.push("Facebook Login success", profileUpdate);
creatCustomeDomain.facebookUrl = "https://www.facebook.com/" + login_userid;
creatCustomeDomain.name = loginusername;
creatCustomeDomain.email = login_user_email;
creatCustomeDomain.gcmId = gcmid;
creatCustomeDomain.gender = response.getString("gender");
creatCustomeDomain.profileImage = "https://graph.facebook.com/" + login_userid + "/picture?type=large";
socialkey = "facebookUrl";
socialurl = "https://www.facebook.com/" + login_userid;
checkCustomerExistance(login_user_email);
} else {
new CustomAlertDialog(context, new CustomAlertDialog.OnDismisslistener() {
@Override
public void onDismiss() {
fblogout();
}
}).showAlertDialog("OOPS!!", "Something went Wrong");
}
//gotoShowQrActivity(creatCustomeDomain);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
profileUpdate.put("Login", "Facebook Login on Cancel");
cleverTap.event.push("Facebook Login on Cancel", profileUpdate);
LoggerUtils.error(LoginActivity.class.getSimpleName(), "on cancel");
}
@Override
public void onError(FacebookException e) {
LoggerUtils.error(LoginActivity.class.getSimpleName(), "on error" + e);
profileUpdate.put("Login", "Facebook Login Error");

});
