我的代碼是：

public void onClick(View v) { 
     String statusText = editStatus.getText().toString(); 
     Twitter twitter = new Twitter("username", "password"); 
     twitter.setStatus(statusText); 
     Log.d("StatusActivity","onClicked with text :"+statusText); 
    } 

我使用jtwitter版本2.9.0

Answer 1

你有NetworkOnMainThreadException。

http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html

你是在UI線程上運行的網絡相關操作。使用thread或Asynctask。

http://developer.android.com/reference/android/os/AsyncTask.html

  new TheTask().execute(); 
      // can pass parameters to doinbackground or 
      // can pass param to constructor of asycntask 

然後

class TheTask extends AsyncTask<Void, Void, Void> { 

    protected void doInBackground(Void... params) { 
     try { 
      // your twitter code here 
      // do not update ui ere 
     } catch (Exception e) { 


     } 
     return null; 
    } 
    @Override 
    protected void onPostExecute(Void result) { 
    super.onPostExecute(result);  
    } 
}
