我有一個顯示登錄選項的主要活動，如果用戶點擊用FB按鈕登錄，我會打電話fblogin（）;，如果登錄成功，那麼我會做意圖打開家庭活動。在Facebook登錄後打開兩次意圖活動
現在，家庭活動似乎打開兩次。 （我可以看到它出現兩次，堆疊）
private void Fblogin()
{
callbackmanager = CallbackManager.Factory.create();
// Set permissions
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile, email, user_birthday,user_friends"));
LoginManager.getInstance().registerCallback(callbackmanager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.d("LoginActivity", response.toString());
Log.d("LoginActivity", object.toString());
String jsonresult = String.valueOf(object);
System.out.println("JSON Result" + jsonresult);
String str_firstname=null,str_id=null;
try {
str_firstname=object.getString("name");
str_id = object.getString("id");
String str_email = object.getString("email");
Intent home = new Intent(MainActivity.this , HomeActivity.class);
home.putExtra("name", str_firstname);
home.putExtra("URL", "https://graph.facebook.com/" + str_id + "/picture?width="+PROFILE_PIC_SIZE+"&height="+PROFILE_PIC_SIZE);
startActivity(home);
} catch (JSONException e) {
e.printStackTrace();
Log.d("xxxx","aa");
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
Log.v("LoginActivity", "cancel");
}
@Override
public void onError(FacebookException exception) {
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
在我的主要活動，我把這個在我的上創建FacebookSdk.sdkInitialize（getApplicationContext（））;
，II還檢查初始登錄狀態`
if (AccessToken.getCurrentAccessToken() != null && Profile.getCurrentProfile()!=null) {
Intent home = new Intent(MainActivity.this , HomeActivity.class);
startActivity(home);}
，但我認爲，初步覈實有沒有什麼關係呢becauseI試圖刪除它太多，但它仍然happening.`
和在我的家庭活動中，我還沒有寫任何Facebook相關的代碼。
編輯：我把整個代碼（MainActivity）

如果可能，請發佈您的整個班級。 – Wizard
這是因爲你是在你登錄後的兩個startCtrivity中的mainactivity被調用的！ –
@Wizard，我更新了代碼。 –
