在这里,我无法获得accessToken甚至个人资料图片。
不知道我做错了什么。
请帮忙。
我把一切都搞定了。
package com.example;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
import android.widget.Toast;
import com.facebook.*;
import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.Profile;
import com.facebook.login.LoginManager;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;
import com.facebook.login.widget.ProfilePictureView;
public class MainActivity extends AppCompatActivity {
CallbackManager callbackManager;
public String accessToken;
private ProfilePictureView profilePictureView;
String name;
TextView fname;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(this.getApplicationContext());
setContentView(R.layout.activity_main);
fname = (TextView) findViewById(R.id.textView);
profilePictureView = (ProfilePictureView) findViewById(R.id.profilePicture);
callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile","email", "user_friends");
// If using in a fragment
//loginButton.setFragment(MainActivity.this);
// Other app specific specialization
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
accessToken = String.valueOf(loginResult.getAccessToken());
Toast.makeText(getBaseContext(),accessToken,Toast.LENGTH_LONG).show();
Profile profile = Profile.getCurrentProfile();
name = profile.getFirstName();
fname.setText(name);
profile = Profile.getCurrentProfile();
profilePictureView.setProfileId(profile.getId());
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
Toast.makeText(getBaseContext(),exception.toString(),Toast.LENGTH_LONG).show();
}
});
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback() {
@Override
public void onSuccess(Object o) {
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException error) {
Toast.makeText(getBaseContext(),error.toString(),Toast.LENGTH_LONG).show();
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
}
我正在尝试显示名称和dp。 没有获得访问令牌。 感谢。

要响应登录结果,您需要使用LoginManager或LoginButton注册回调。如果您使用LoginButton注册回调,则不需要在登录管理器上注册回调。
首先卸妆LoginManager
。
现在,您可以使用GraphRequest
获取用户的数据,以下是您的操作方法。
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
final ProgressDialog pd = new ProgressDialog(Login.this);
pd.setMessage("Please Wait..");
String accessToken = loginResult.getAccessToken().getToken();
Log.i("accessToken", accessToken);
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object,
GraphResponse response) {
Log.i("LoginActivity",
response.toString());
try {
id = object.getString("id");
try {
URL profile_pic = new URL(
"https://graph.facebook.com/" + id + "/picture?type=large");
user_image = profile_pic.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
}
name = object.getString("name");
email = object.getString("email");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields",
"id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
pd.show();
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
Toast.makeText(getBaseContext(),exception.toString(),Toast.LENGTH_LONG).show();
}
});
了解有关GraphRequest
Graph API
快乐编码。
