Afinal这个超级强大框架，可以满足下面功能，并且基本覆盖了手机应用中的核心部分

数据库(几句话就能实现增删改查)

注解 (省去findById和setOnclickListener)

网络通信(get请求 / post请求 / 文件上传 / 文件下载)

图片获取(一句话解决)

下面是实现的例子，并且放上服务器的代码：

public class MainAct extends FinalActivity {

@ViewInject(id = R.id.aBt, click = "dbClick")//实现注解

Button abButton;

@ViewInject(id = R.id.getBt, click = "getClick")

Button getButton;

@ViewInject(id = R.id.postBt, click = "postClick")

Button postButton;

@ViewInject(id = R.id.tv)

TextView textView;

@ViewInject(id = R.id.fileBt, click = "fileClick")

Button fileButton;

@ViewInject(id = R.id.fileBt2, click = "fileClick2")

Button fileButton2;

@ViewInject(id = R.id.picBt, click = "picClick")

Button picButton;

@ViewInject(id = R.id.img)

ImageView imageView;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.afinallay);

}

public void picClick(View v) {

Toast.makeText(getApplicationContext(), "in", 2000).show();

FinalBitmap finalBitmap = FinalBitmap.create(this);

finalBitmap

.display(

imageView,

"http://e.hiphotos.baidu.com/image/pic/item/b999a9014c086e06d1925b1300087bf40ad1cbb4.jpg");

}

public void fileClick2(View v) {//文件下载

FinalHttp finalHttp = new FinalHttp();

AjaxParams ajaxParams = new AjaxParams();

try {

HttpHandler handler = finalHttp.download(

"http://192.168.191.1:8080/androidtest/a.doc",

Environment.getExternalStorageDirectory() + "/im.doc", true,

new AjaxCallBack() {

@Override

public void onSuccess(File t) {

// TODO Auto-generated method stub

textView.setText("File down Success");

}

});

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public void fileClick(View v) {//文件上传

FinalHttp finalHttp = new FinalHttp();

AjaxParams ajaxParams = new AjaxParams();

try {

ajaxParams.put("file",

new File(Environment.getExternalStorageDirectory()

+ "/n.jpg"));

finalHttp.post("http://192.168.191.1:8080/androidtest/test3",

ajaxParams, new AjaxCallBack() {

@Override

public void onSuccess(Object t) {

// TODO Auto-generated method stub

textView.setText((t == null) ? "null" : (String) t);

}

});

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public void getClick(View v) { //get请求

FinalHttp finalHttp = new FinalHttp();

AjaxParams params = new AjaxParams();

params.put("id", "1");

params.put("name", "duerGet");

params.put("age", "521");

finalHttp.get("http://192.168.191.1:8080/androidtest/test2", params,

new AjaxCallBack() {

@Override

public void onSuccess(Object t) {

// TODO Auto-generated method stub

if (textView == null)

Toast.makeText(getApplicationContext(),

"(textView==null)", 2000).show();

else

textView.setText((t == null) ? "null" : (String) t);

}

});

}

public void postClick(View v) { //post请求

FinalHttp finalHttp = new FinalHttp();

AjaxParams params = new AjaxParams();

params.put("name", "duerPost");

params.put("pass", "125");

finalHttp.post("http://192.168.191.1:8080/androidtest/test2", params,

new AjaxCallBack() {

@Override

public void onSuccess(Object t) {

// TODO Auto-generated method stub

textView.setText((t == null) ? "null" : (String) t);

}

});

}

public void dbClick(View v) {//创建数据库 [email protected](name="tablename")实现自定义表名

Toast.makeText(getApplicationContext(), "in", 2000).show();

FinalDb finalDb = FinalDb.create(this, "UserDB");

UserBean bean1 = new UserBean();

bean1.setAge("12");

bean1.setName("duzi");

finalDb.save(bean1);

UserBean bean2 = new UserBean();

bean2.setAge("12");

bean2.setName("duzi");

finalDb.save(bean2);

}

}

服务器上传接收代码：

public class FileUpload extends HttpServlet {

@Override

protected void doPost(HttpServletRequest request,

HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

boolean isUpload = ServletFileUpload.isMultipartContent(request);

if (isUpload) {

DiskFileItemFactory factory = new DiskFileItemFactory();

factory.setSizeThreshold(10);

factory.setRepository(new File("E:\\upload"));

ServletFileUpload upload = new ServletFileUpload(factory);

upload.setSizeMax(10);

ServletFileUpload sfu = new ServletFileUpload(factory);

try {

List DiskFileItems = sfu.parseRequest(request);

for (FileItem item : DiskFileItems) {

System.out.println("-------------key:"

+ item.getFieldName());

System.out.println(item.getName());

File myFile=new File("E:\\upload\\"+item.getName());

try {

item.write(myFile);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

// System.out.println("-------------value:"+

// item.getString());

// System.out.println("-------------inputSream:"+

// item.getInputStream());

}

} catch (FileUploadException e) {

e.printStackTrace();

}

}

response.getWriter().print("okok!");

}

}
