這是facebook集成工作代碼：
1）創建一個XML：fragment_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:orientation="vertical"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivityFragment">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/textView"
android:layout_centerHorizontal="true"/>
<com.facebook.login.widget.LoginButton
android:id="@+id/login_button"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
2）的Java類即MainFragment.java
package example.com.facebook_integration;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;

/**

*/
public class MainFragment extends Fragment {
private CallbackManager callbackManager;
private TextView textView;
private AccessTokenTracker accessTokenTracker;
private ProfileTracker profileTracker;
private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
displayMessage(profile);
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException e) {
}
};
public MainFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
accessTokenTracker= new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
profileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
displayMessage(newProfile);
}
};
accessTokenTracker.startTracking();
profileTracker.startTracking();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
final ImageView imageView=(ImageView)view.findViewById(R.id.myImage);
textView = (TextView) view.findViewById(R.id.textView);
//loginButton.setReadPermissions("user_likes");
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, callback);
loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday","user_likes","user_friends"));
callbackManager = CallbackManager.Factory.create();
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(final JSONObject object, GraphResponse response)
{
Log.v("LoginActivity", response.toString());
try
{
// Application code
System.out.println("JSONRESPOMSEEE "+response.toString());
String email = object.getString("email");
String birthday = object.getString("birthday"); // 01/31/1980 format
String name = object.getString("name");
Profile profile = Profile.getCurrentProfile();
Uri uri=(Uri)profile.getProfilePictureUri(200,200);
System.out.println("Email "+email+" Birthday "+birthday+name);
System.out.println("Email " + uri);
final ArrayList arrayList=new ArrayList();
new GraphRequest(

null,

new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
try {

JSONArray jarray = json.getJSONArray("data");
for (int i = 0; i < jarray.length(); i++) {
JSONObject likes = jarray.getJSONObject(i);
String likeId = likes.getString("id");
String likeName = likes.getString("name");
String likeCreatedTime = likes.getString("created_time");
arrayList.add("Page Name "+likeName+" Time= "+likeCreatedTime+" ID= "+likeId);
System.out.println("My Name " + likeName + " " + likeCreatedTime);
}
System.out.println("ArrayList mine "+arrayList);
System.out.println("ArrayList mine size "+arrayList.size());
}
catch(Exception e)
{

}
}
).executeAsync();
}
catch (Exception e)
{
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
// App code

});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
private void displayMessage(Profile profile) {
if(profile != null){
textView.setText(profile.getName());
}
}
@Override
public void onStop() {
super.onStop();
accessTokenTracker.stopTracking();
profileTracker.stopTracking();
}
@Override
public void onResume()
{
super.onResume();
Profile profile = Profile.getCurrentProfile();
displayMessage(profile);
}
}
3）Cr eate一個多個XML：activity_main.xml中
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
<fragment
android:id="@+id/fragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="example.com.facebook_integration.MainFragment"
></fragment>
</RelativeLayout>
4）創建MainActivity.java
package example.com.facebook_integration;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import net.simplifiedcoding.androidlogin.R;
public class MainActivity extends AppCompatActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

但我已經做了所有我的代碼，你可以的重要變化遵循上述所有步驟後使用此代碼。
