如何使AsyncTask的模块化机器人

问题描述：

我很新的Android开发。我工作在一个应用程序，我需要做大量的异步调用的API。对于每一个API调用，我必须一遍又一遍写的外观相似的AsyncTask类。那么，有没有什么办法让这些异步调用模块？

I am quite new to Android Development. I am working in a app where i need to make a lot of async calls to api. For each and every API call, I have to write the similar looking AsyncTask class over and over again. So, is there any way to make these Async Calls modular?

答

是有可能使用监听器和AsyncTask的使用参数的构造函数

yes it is possible use Listener and AsyncTask with parameterized constructor

快来看

创建接口

public interface OnTaskCompletListerner {
 void oncompleteListerner(String name);
}

创建的AsyncTask类如下：

create an AsyncTask class as follows

public class AsyncTaskModuler  extends AsyncTask<Void, Void, String> {

    private Context context;
    private HashMap<String, String> data;
    private String URL;
    private OnTaskCompletListerner taskdone;

    public AsyncTaskModuler(Context ctx,HashMap<String, String> data,String url,OnTaskCompletListerner taskdone){

        this.context=ctx;
        this.data=data;
        this.URL=url;
        this.taskdone=taskdone;
    }

    @Override
    protected String doInBackground(Void... params) {
        //Do the task here and return the value if needed 
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        taskdone.oncompleteListerner(result);
    }

和调用它像这样的活动

public class CallAync extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String url="";
        HashMap<String, String> data=new HashMap<String, String>();
        AsyncTaskModuler moduler=new AsyncTaskModuler(CallAync.this, data, url, completListerner);
        moduler.execute();
    }

    OnTaskCompletListerner completListerner=new OnTaskCompletListerner() {

        @Override
        public void oncompleteListerner(String name) {

        }
    };
}
