我正在学习实施Google登录集成.
我正在关注Google Developers的演示.
这是我的登录页面代码：
public class LoginActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener, View.OnClickListener {
private Button btnSignOut, btnDisconnect;
private SignInButton btnSignIn;
private ProgressDialog mProgressDialog;
private static final String TAG = "LoginActivity";
private TextView mStatusTextView;
GoogleApiClient mGoogleApiClient;
private static final int RC_SIGN_IN = 9001;
private Button btnNext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
initInstances();
}
private void initInstances() {
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mStatusTextView = (TextView) findViewById(R.id.status);
btnSignOut = (Button) findViewById(R.id.sign_out_button);
btnDisconnect = (Button) findViewById(R.id.disconnect_button);
btnSignIn = (SignInButton) findViewById(R.id.sign_in_button);
btnSignIn.setSize(SignInButton.SIZE_STANDARD);
btnSignIn.setScopes(gso.getScopeArray());
btnSignIn.setOnClickListener(this);
btnSignOut.setOnClickListener(this);
btnDisconnect.setOnClickListener(this);
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d(TAG, "onConnectionFailed:" + connectionResult);
Toast.makeText(LoginActivity.this, "" + connectionResult, Toast.LENGTH_SHORT).show();
}
@Override
public void onStart() {
super.onStart();
OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (opr.isDone()) {
// If the user's cached credentials are valid, the OptionalPendingResult will be "done"
// and the GoogleSignInResult will be available instantly.
Log.d(TAG, "Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result);
} else {
// If the user has not previously signed in on this device or the sign-in has expired,
// this asynchronous branch will attempt to sign in the user silently. Cross-device
// single sign-on will occur in this branch.
showProgressDialog();
opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
@Override
public void onResult(GoogleSignInResult googleSignInResult) {
hideProgressDialog();
handleSignInResult(googleSignInResult);
}
});
}
}
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();
}
}
// [START onActivityResult]
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
}
private void handleSignInResult(GoogleSignInResult result) {
Log.d(TAG, "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName()));
updateUI(true);
//Log.d(TAG, "photoUrl "+result.getSignInAccount().getPhotoUrl());
Intent iNext = new Intent(LoginActivity.this, ProfileInfoActiviy.class);
iNext.putExtra("userId", acct.getId());
iNext.putExtra("userName", acct.getDisplayName());
if (acct.getPhotoUrl() != null) {
iNext.putExtra("userPhoto", acct.getPhotoUrl().toString());
}
iNext.putExtra("userEmail", acct.getEmail());
startActivity(iNext);
} else {
// Signed out, show unauthenticated UI.
updateUI(false);
}
}
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
// [START signOut]
private void signOut() {
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
// [START_EXCLUDE]
updateUI(false);
// [END_EXCLUDE]
}
});
}
// [END signOut]
// [START revokeAccess]
private void revokeAccess() {
Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
// [START_EXCLUDE]
updateUI(false);
// [END_EXCLUDE]
}
});
}
private void updateUI(boolean signedIn) {
if (signedIn) {
findViewById(R.id.sign_in_button).setVisibility(View.GONE);
findViewById(R.id.sign_out_and_disconnect).setVisibility(View.VISIBLE);
} else {
mStatusTextView.setText(R.string.signed_out);
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_and_disconnect).setVisibility(View.GONE);
}
}
private void intentToInfo() {
/* Intent iNext=new Intent(LoginActivity.this,ProfileInfoActiviy.class);
startActivityForResult(iNext,);*/
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.sign_in_button:
signIn();
break;
case R.id.sign_out_button:
signOut();
break;
case R.id.disconnect_button:
revokeAccess();
break;
}
}
}
在Google Developers演示中,他们已经解释了如何退出,但它来自同一个活动.我想从下一个/另一个活动注销,如下所示：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile_info_activiy);
ButterKnife.bind(this);
String uId = getIntent().getExtras().getString("userId");
String uName = getIntent().getExtras().getString("userName");
String uEmail = getIntent().getExtras().getString("userEmail");
if (getIntent().getExtras().getString("userPhoto") != null) {
uPhoto = getIntent().getExtras().getString("userPhoto");
}
tvUserId.setText(uId);
tvUserName.setText(uName);
tvEmailId.setText(uEmail);
loadImage(uPhoto);
btnSignOut.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(ProfileInfoActiviy.this, "Logged Out" , Toast.LENGTH_SHORT).show();
}
});
我不能从这里退出coz mGoogleApiClient在这里将为null.
有任何想法吗？？
解决方法:
将以下代码放入任何活动中.
用户单击“注销”按钮时尝试此操作：
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
}
});
把它放在onCreate()中：
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API)
.build();
然后像这样覆盖onStart()
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
