Google plus从一个活动登录（此活动以共享首选项存储登录详细信息）并从另一个活动注销（此活动会检索登录详细信息）.Logout活动具有注销按钮。 我的问题：我需要从第一个活动（AndroidGooglePlusExample）登录，登录详细信息（用户名，userimage，emailid）存储在共享首选项中。我在第二个活动（HomePage）中检索这些值，并在那里显示它，从第二个活动我需要在点击退出按钮时注销。请帮我解决这个问题。这是我的登录活动

这是我的第二项活动
public class HomePage extends Fragment {
SharedPreferences mPrefs;
Button logout_btn;
// Google client to communicate with Google
private GoogleApiClient mGoogleApiClient;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.activity_home_page, container, false);
// TextView name =(TextView)rootView.findViewById(R.id.username);
// TextView emailid =(TextView)rootView.findViewById(R.id.email);
// ImageView myimage=(ImageView)rootView.findViewById(R.id.image);
logout_btn=(Button)rootView.findViewById(R.id.logout);
logout_btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Editor editor = mPrefs.edit();
String name = mPrefs.getString("Guser_name", "");
Log.d("", name);
String pic = mPrefs.getString("Guserpic_url", "");
String email = mPrefs.getString("Guser_email", "");
}
public void logout(View v) {
googlePlusLogout();
}
private void googlePlusLogout() {
if (mGoogleApiClient.isConnected()) {
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
mGoogleApiClient.disconnect();
mGoogleApiClient.connect();
// updateProfile(false);
}
}
});
return rootView;
}
}
this is my login xml

答案 0 :(得分：0)
根据最初的聊天讨论，您有一个实现Android Login with Google Plus Account的工作代码示例，但您需要根据您的要求对其进行修改。我只能提出一个想法，但无法给出一个例子!!
所以这是我的建议，以满足你的任务完成。
