我的代码是：

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);
    }

我正在使用jtwitter版本2.9.0

Answer 1

您有NetworkOnMainThreadException。

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

您正在ui线程上运行与网络相关的操作。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

然后

 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);    
    }
}

jtwitter没有发布到Twitter，应用程序崩溃
