一个Android异步调用的简单框架

1 异步需要执行的函数，完成需要做的事

定义一个接口，完成异步需要干的活:

public interface ThreadDoSomethingObj {

public ThreadExecuteResult DoSomething(Object input_obj);

}

2 异步执行完成后，执行结果的返回和执行数据的输出

定义一个输出结果类，输出result和Serializable 的对象:

public class ThreadExecuteResult {

int m_result;

Serializable m_obj;

public ThreadExecuteResult(int result, Serializable obj)

{

m_result = result;

m_obj = obj;

}

public void SetResult(int result)

{

m_result = result;

}

public int GetResult()

{

return m_result;

}

public void SetObj(Serializable obj)

{

m_obj = obj;

}

public Serializable GetObj()

{

return m_obj;

}

}

3 运行异步执行函数的线程管理类，可以在里面实现一个线程池的东东:

import android.os.Handler;

import android.os.Looper;

import android.os.Message;

public class ThreadMgr extends Thread {

private ThreadDoSomethingObj m_thread_handler;

private Handler m_msg_handler;

private Object m_input_obj;

public ThreadMgr(Object input_obj,

ThreadDoSomethingObj thread_handler,

Handler callback_handle) {

m_thread_handler = thread_handler;

m_msg_handler = callback_handle;

m_input_obj = input_obj;

}

@Override

public void run() {

Looper.prepare();

ThreadExecuteResult result = m_thread_handler.DoSomething(m_input_obj);

Notify(result);

Looper.loop();

}

private void Notify(ThreadExecuteResult result)

{

Message msg = new Message();

msg.what = result.GetResult();

msg.getData().putSerializable("Object", result.GetObj());

m_msg_handler.sendMessage(msg);//

}

}
