Android Asynctask传递单个字符串

Question

我想将一个字符串传递给asynctask.谁能告诉我它是如何完成的？我的getEntity需要方法getEntity(Activity,String,EntityGetListener)但我继续传递这个String []

String pass= story.get(position).getEntity();

        new RemoteDataTask().execute(pass);





private class RemoteDataTask extends AsyncTask<String, String, Long> {

    @Override
    protected Long doInBackground(String... params) {
        // TODO Auto-generated method stub
        EntityUtils.getEntity(activity, params, new EntityGetListener() {
            @Override
            public void onGet(Entity entity) {

                viewcount = entity.getEntityStats().getViews();
            }

            @Override
            public void onError(SocializeException error) {

            }
        });
        return null;
    }

}

Answer 1

你已经有了这个

     new RemoteDataTask().execute(pass); // assuming pass is a string

在 doInbackground

     @Override
     protected Long doInBackground(String... params) {   

             String s = params[0]; // here's youre string
             ...      //rest of the code. 
     }

Answer 2

您可以AsyncTask使用构造函数进行构建.

public class RemoteDataTask extends AsyncTask<String, String, Long> {

    private String data;

    public RemoteDataTask(String passedData) {
        data = passedData;
    }

    @Override
    protected String doInBackground(Context... params) {
        // you can access "data" variable here.
        EntityUtils.getEntity(activity, params, new EntityGetListener() {
            @Override
            public void onGet(Entity entity) {
                viewcount = entity.getEntityStats().getViews();
            }
            @Override
            public void onError(SocializeException error) {
            }
        });
        return null;
    }
}

在应用程序(Activity,Service等等),即可使用;

private RemoteDataTask mTask;
private void doStuff(){
    String pass = "meow"; // story.get(position).getEntity();
    mTask = new RemoteDataTask(pass);
    mTask.execute();
}
