如何将 Twitter Fabric Session 从 Activity 发送到另一个 Activity？

Question

我想将 Twitter 会话从 activity 发送到另一个 activity.I 已搜索（How to pass an object from one activity to another on Android）但是可序列化的 TwitterSession 有问题。该场景是当用户成功登录时，此会话信息将转到 MainActivity。这是我的代码。我哪里错了？

TwitterSessionObject.java

import com.twitter.sdk.android.core.TwitterSession;
import java.io.Serializable;

public class TwitterSessionObject implements Serializable {

    private TwitterSession session;

    public TwitterSessionObject(TwitterSession twitterSession){

        this.session = twitterSession;
    }    
    public TwitterSession getTwitterSession() {
        return session;
    }
    public void setSession(TwitterSession session) {
        this.session = session;
    }
}

Login.java

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
        Fabric.with(this, new Twitter(authConfig));
        setContentView(R.layout.activity_login);

        loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);
        loginButton.setCallback(new Callback<TwitterSession>() {
            @Override
            public void success(Result<TwitterSession> result) {
                // Do something with result, which provides a TwitterSession for making API calls

                TwitterSession session = Twitter.getSessionManager().getActiveSession();
                TwitterAuthToken authToken = session.getAuthToken();
                String token = authToken.token;
                String secret = authToken.secret;

                TwitterSessionObject sessionObject = new TwitterSessionObject(session);

                Intent intent = new Intent(Login.this, MainActivity.class);
                intent.putExtra("Session", sessionObject);
                startActivity(intent);       
            }

            @Override
            public void failure(TwitterException exception) {
                // Do something on failure
            }
        });
    }

MainActivity.java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Intent intent = getIntent();
        TwitterSessionObject session = (TwitterSessionObject)intent.getSerializableExtra("Session");          
    }

Answer 1

你不能这样通过。 TwitterSession 不可序列化，因此您不能使其成为可序列化 class.

的成员

由于 TwitterSession 是单例的，您可以简单地从 MainActivity 中调用以下方法

TwitterSession session = Twitter.getSessionManager().getActiveSession();

所以你的 activity 代码看起来像

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TwitterSession session = Twitter.getSessionManager().getActiveSession();

}

Answer 2

在您的 MainActivity 中：

public class MainActivity extends Activity {

private TwitterLoginButton loginButton;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SharedPreferences prefs = getPreferences(MODE_PRIVATE);
    Boolean restoredText = prefs.getBoolean("loginStatus", false);
    if (restoredText == true) {
        startActivity(new Intent(this, YourTwitterClass.class));
        finish(); // destroy login so user can't come back with back button
    }

    loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);
    loginButton.setCallback(new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {

        startActivity(new Intent(this, YourTwitterClass.class));

        }

        @Override
        public void failure(TwitterException exception) {
        //do something
        }
    });
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    loginButton.onActivityResult(requestCode, resultCode, data);
}
