我已经完成了与google plus登录和注销相关的一些stackoverflow问题。而且大多数都已经过时了。我无法实现我真正想要的东西。
我退出后，下次登录时，我希望用户选择可用的Google帐户再次登录。
我正在使用自定义登录和注销按钮。对于注销，我有两种情况，
这是我到目前为止实施的内容：
public class LoginActivity extends AppCompatActivity implements OnClickListener{
private static final int RC_SIGN_IN = 9001;
private GoogleApiClient mGoogleApiClient;
private ConnectionResult mGoogleConnectionResult;
private Button login;
private ProgressDialog mProgressDialog;
private Context mContext;
private String mUri;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext= LoginActivity.this;
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.login_layout);
login= (Button) findViewById(R.id.lg_login_btn);
login.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if(isOnline(mContext)){
if(v.getId()== R.id.lg_login_btn) {
if(mGoogleApiClient!=null){
mGoogleApiClient.disconnect();
}
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestScopes(new Scope(Scopes.PLUS_LOGIN))
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(mContext.getApplicationContext())
.enableAutoManage(this , mGPlusConnectionFailedListener)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addApi(Plus.API)
.build();
signOutGPlus();
Intent lSignInIntent= Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(lSignInIntent, RC_SIGN_IN);
}
} else{
showAlertDialog(mContext, "Error", "Please check internet connection");
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
logD("&&onActivityResult", "requestCode: "+requestCode); // first
if (requestCode == RC_SIGN_IN) {
if(resultCode == RESULT_OK){
showProgressDialog();
getGPlusUserInfo(data);
} else {
logD("&&onActivityResult", "requestCode: RESULT_ NOT Ok"+requestCode);
}
}
}
GoogleApiClient.OnConnectionFailedListener mGPlusConnectionFailedListener= new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
logD("&&mGPlusConnectionFailedListener", "onConnectionFailed");
}
};
private void getGPlusUserInfo(Intent data){
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
private void handleSignInResult(GoogleSignInResult result) {
Log.d("&&handleSignInResult", "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
String lDisplayName="";
String lEmail="";
String lFirstName="";
String lLastName="";
String lGender="";
// G+
if (mGoogleApiClient.hasConnectedApi(Plus.API)) {
logD("&&GPlusUserInfo", "&hasConnectedApi--------------------------------");
// Deprecated
Person person = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
if(null != person) {
logD("&&GPlusUserInfo", "&--------------------------------");
logD("&&GPlusUserInfo", "&Display Name: " + person.getDisplayName());
lDisplayName= person.getDisplayName();
logD("&&GPlusUserInfo", "Gender: " + person.getGender());
if(person.getGender()< MyHalConstants.GENDER.length){
lGender= MyHalConstants.GENDER[person.getGender()];
} else{
lGender= "Other";
}
}
}
GoogleSignInAccount acct = result.getSignInAccount();
if(null != acct) {
if (null != acct.getDisplayName()) {
logD("&&GPlusUserInfo", "&Display Name: " + acct.getDisplayName());
}
lFirstName= acct.getGivenName();
lLastName= acct.getFamilyName();
// Views inside NavigationView's header
Uri uri = acct.getPhotoUrl();
}
} else {
// Signed out, show unauthenticated UI.
signOutGPlus();
}
}
// sign - out
private void signOutGPlus(){
logD("&&signOutGPlus", "signOutGPlus");
if(null != mGoogleApiClient){
mGoogleApiClient.connect();
mGoogleApiClient.registerConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(@Nullable Bundle bundle) {
if(mGoogleApiClient.isConnected()) {
logD("&&signOutGPlus", "inside");
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
logD("&&signOutGPlus", "onResult");
if(mGoogleApiClient.isConnected()){
mGoogleApiClient.clearDefaultAccountAndReconnect();
mGoogleApiClient.disconnect();
}
// Deprecated
/*Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
//Plus.AccountApi.revokeAccessAndDisconnect(mGoogleApiClient);
//revokeAccess();*/
}
}
);
}
}
@Override
public void onConnectionSuspended(int i) {
}
});
}
}
// Not used
private void revokeAccess() {
logD("&&revokeAccess", "revokeAccess");
Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
// ...
}
});
}
private void showProgressDialog() {
if (mProgressDialog == null) {
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage(getString(R.string.loading));
mProgressDialog.setIndeterminate(true);
}
mProgressDialog.show();
}
private void hideProgressDialog() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.hide();
}
}
private void showAlertDialog(Context pContext, String pTitle, String pMessage){
AlertDialog.Builder ldialogBuilder= new AlertDialog.Builder(pContext);
ldialogBuilder.setTitle(pTitle)
.setMessage(pMessage)
.setPositiveButton("Ok", null);
ldialogBuilder.show();
}
private void dismissDialog(){
if(null != mProgressDialog){
mProgressDialog.dismiss();
mProgressDialog= null;
}
}
}
至于来自不同活动的退出，我遇到的答案都没有定义如何在新活动中初始化 mGoogleApiClient 。
如果我实施以下代码，则退出：
private GoogleApiClient mGoogleApiClient;
// sign - out
private void signOutGPlusFromDifferentActivity(){
logD("&&signOutGPlus", "signOutGPlus");
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestScopes(new Scope(Scopes.PLUS_LOGIN))
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(mContext.getApplicationContext())
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addApi(Plus.API)
.build();
if(null != mGoogleApiClient){
mGoogleApiClient.connect();
mGoogleApiClient.registerConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(@Nullable Bundle bundle) {
if(mGoogleApiClient.isConnected()) {
logD("&&signOutGPlus", "inside");
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
logD("&&signOutGPlus", "onResult");
if(mGoogleApiClient.isConnected()){
mGoogleApiClient.clearDefaultAccountAndReconnect();
mGoogleApiClient.disconnect();
}
}
}
);
}
}
@Override
public void onConnectionSuspended(int i) {
}
});
}
}
它会抛出错误。
通过从登录活动中删除退出部分，我可以从GPlus正确登录。
摇篮：
compile 'com.google.android.gms:play-services-auth:9.2.1'
compile 'com.google.android.gms:play-services:9.2.1'
注意：从登录活动我可以从google plus或face-book登录。
活动A（从g +或fb登录）。
登录后，用户将被定向到活动B，来自活动B的用户可以从相应的门户网站（g +或fb）注销。
Facebook部分已经完成。只剩下就是g +。
通过使用更新的GOOGLE LOGIN LOGOUT API，请帮助正确退出。
答案 0 :(得分：1)
对于注销，您可以使用以下方法：
private void signOut() {
Auth.GoogleSignInApi.signOut(googleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
Timber.d("Logged out");
}
});
}
登录时，您可以按照以下方法操作：
public void onActivityResult(Activity activity, int requestCode, int resultCode, Intent data) {
this.activity = activity;
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
/*For inintializing googleapiclient*/
private void initGoogleClient() {
gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
googleApiClient = new GoogleApiClient.Builder(activity)
.enableAutoManage((FragmentActivity) activity /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addOnConnectionFailedListener(this)
.addApi(Plus.API)
.addScope(new Scope(Scopes.PROFILE))
.build();
}
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(googleApiClient);
activity.startActivityForResult(signInIntent, RC_SIGN_IN);
}

我退出后，下次登录时，我希望用户选择可用的Google帐户再次登录。
诀窍是在用户点击Google登录按钮登录后立即 clearDefaultAccountAndReconnect GoogleApiClient 。 这可确保您在点击“登录”按钮时始终显示所有可用的Google帐户。
第1步：初始化GoogleAPIClient并将onClickListener设置为Activity onCreate（）
中的googleSignInButtonprivate GoogleApiClient mApiClient;
private void initializeGoogleSignIn() {
GoogleSignInOptions signInOptions = new GoogleSignInOptions
.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestProfile()
.build();
mApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API, signInOptions)
.build();
SignInButton googleSignInButton = (SignInButton) findViewById(R.id.google_sign_in);
googleSignInButton.setOnClickListener(this);
}
第2步：通过onClick（）方法处理Google登录
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.google_sign_in:
if (mApiClient.isConnected()) {
mApiClient.clearDefaultAccountAndReconnect();
} else {
mApiClient.connect();
}
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
break;
}
}
<强> MISCALLANEOUS
// Make sure you connect and disconnect the GoogleApiClient in onStart and onStop lifecycle methods
@Override
protected void onStart() {
super.onStart();
mApiClient.connect();
}
@Override
protected void onStop() {
super.onStop();
if (mApiClient.isConnected())
mApiClient.disconnect();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result != null && result.isSuccess()) {
GoogleSignInAccount account = result.getSignInAccount();
setAppPreferenceData(account.getId(), account.getEmail(), String.valueOf(account.getPhotoUrl()), account.getDisplayName());
startActivity(new Intent(this, NavigationActivity.class));
finish();
} else {
mProgressLayout.setVisibility(View.GONE);
if (Utils.isNetworkAvailable(this))
Toast.makeText(this, "Google Authentication Failed! Please try again", Toast.LENGTH_SHORT).show();
else
Toast.makeText(this, "Network Error! Please connect to your wifi.", Toast.LENGTH_LONG).show();
}
}
}
为什么在代码中需要这么多的回调方法？我想你的代码有点复杂了。 主要技巧是在用户尝试登录时断开并清除默认帐户，以确保始终显示有效的Google帐户列表。 我使用了相同的程序，经过了尝试，测试和工作。
我的应用中使用的登录状态只有一种回调方法。
public class SignInActivity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(SignInActivity.this, "Google Play connection error", Toast.LENGTH_SHORT).show();
mProgressLayout.setVisibility(View.GONE);
}

我退出后，下次登录时，我希望用户选择可用的Google帐户再次登录。
只需在用户点击退出按钮时退出用户并撤消访问权限。下次，当用户尝试登录时，他/她将被要求选择他们喜欢的谷歌帐户。
由于您正在登录并退出不同的活动，因此您最终会遇到重复的代码。不要复制代码，只需使用帮助程序类并初始化Google SignIn Option和Google API Client。现在，只要您想使用Google API客户端，就可以初始化帮助程序类。
案例1。如果您想在登录前退出，请使用clearDefaultAccountAndReconnect。
案例2。要退出用户（不管活动是什么），请使用Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback。
这是项目的github link。如果你还有疑问，可以看看。
答案 3 :(得分：0)
这解决了我的问题：-
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
Toast.makeText(context, "Success"+status.getStatusMessage(), Toast.LENGTH_SHORT).show();
}
});
