在doInBackground AsyncTask Android中传递更多值 [英] Pass more values in doInBackground AsyncTask Android

问题描述

如何在 doInBackground

我的 AsyncTask 看起来像这样.

private class DownloadFile extends AsyncTask<String, Integer, String> {
        @Override
        protected String doInBackground(String... sUrl) {
        {

        }
}

是否有可能以其他方式在受保护的String DoInBackground

Is it possible somehow to pass more values on my protected String DoInBackground

例如:受保护的字符串doInBackground(String ... sUrl，String ... otherUrl，Context context)

以及之后如何执行 AsyncTask ? new DownloadFile.execute("，"，this)或其他内容?

And how to execute the AsyncTask after? new DownloadFile.execute("","",this) or something?

推荐答案

String... sUrl

三个连续的点意味着一个字符串以上.点是可变参数

the three consecutive dots meaning more then one String. The dots are varargs

以及如何传递上下文?

And how to pass the Context?

您可以强制其添加以Context作为参数的构造函数:

you can force it adding a constructor that takes the Context as parameter:

private Context mContext;
public void setContext(Context context){
    if (context == null) {
      throw new IllegalArgumentException("Context can't be null");
    }
    mContext = context;
}
