我想将Twitter会话从一个活动发送到另一个活动。我已经搜索了(How to pass an object from one activity to another on Android),但是可序列化的TwitterSession出现了错误。该方案是当用户成功登录时,此会话信息将转到MainActivity。这是我的代码。
我怎么了
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");
}
最佳答案
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类的成员。
由于TwitterSession是单例,因此您只需在MainActivity中调用以下方法
TwitterSession session = Twitter.getSessionManager().getActiveSession();
所以你的活动代码看起来像
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TwitterSession session = Twitter.getSessionManager().getActiveSession();
}
