我在异步任务中调用convertResponseToString但是我也有一个按钮，我如何获得logo.feature来显示新活动的输出？基本上我想在新活动中显示消息。有什么建议吗？

点击按钮后，在第一个活动中，您可以发送下一个活动的值，如下所示。

Intent i = new Intent(MainActivity.this,Result.class);     
i.putExtra("Logo","whatever message you want to sent");                      
startActivity(i);

现在你怎么能得到这些先前价值？为此，在结果活动上获取类似这样的值

Intent data =getIntent();
String message= data.getStringExtra("Logo");

如何将异步任务中的值发送到另一个新活动？
