layout中很普通,就是两个button和一个imageview

layout中很普通,就是两个button和一个imageview

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical"
  >
  <button
    android:id="@+id/test"
    android:layout_width="368dp"
    android:layout_height="wrap_content"
    android:text="button1"
    android:textallcaps="false" />
  <button
    android:id="@+id/test2"
    android:layout_width="368dp"
    android:layout_height="wrap_content"
    android:text="button2"
    android:textallcaps="false"
    />
  <imageview
    android:id="@+id/image"
    android:layout_width="0dp"
    android:layout_height="495dp"
    />
</linearlayout>

在主页面中给按钮添加事件:

    button2 = (button)findviewbyid(r.id.test2);
    imageview = (imageview)findviewbyid(r.id.image);
    button1.setonclicklistener(new view.onclicklistener() {//将服务器的图片读取到本地
      public void onclick(view view) {
        okhttpclient okhttpclient = new okhttpclient();
        request request = new request.builder()
                .url("http://115.159.217.226/xy.png")
                 .build();
        okhttpclient.newcall(request).enqueue(new callback() {

            handler.sendmessage(msg);
          }
        });
      }
    });
    button2.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view view) {
        uploadmultifile();
      }
    });
  }
  private void uploadmultifile() {//将图片发送到服务器
    final string url = "http://115.159.217.226/upload.php";
    file file = new file( environment.getexternalstoragedirectory()+"/storage/emulated/0/", "xy.jpg");
    requestbody filebody = requestbody.create(mediatype.parse("application/octet-stream"), file);
    file file2 = new file( environment.getexternalstoragedirectory()+"/storage/emulated/0/", "yyw.jpg");
    requestbody filebody2 = requestbody.create(mediatype.parse("application/octet-stream"), file2);
    requestbody requestbody = new multipartbody.builder()
        .settype(multipartbody.form)
        .addformdatapart("image1", "xy.jpg", filebody)
        .addformdatapart("image2", "yyw.jpg", filebody2)
        .build();
    request request = new request.builder()
        .url(url)
        .post(requestbody)
        .build();
    final okhttp3.okhttpclient.builder httpbuilder = new okhttpclient.builder();
    okhttpclient okhttpclient = httpbuilder
        //设置超时
        .connecttimeout(10, timeunit.seconds)
        .writetimeout(15, timeunit.seconds)
        .build();
    okhttpclient.newcall(request).enqueue(new callback() {
      @override
      public void onfailure(call call, ioexception e) {
        log.e("aa", "uploadmultifile() e=" + e);
      }
      @override
      public void onresponse(call call, response response) throws ioexception {
        log.i("bb", "uploadmultifile() response=" + response.body().string());
      }
    });
  }
}

服务器端代码:

  <?php
   header('content-type: application/json;charset=utf-8');
if(empty($_files)) die('{"status":0,"msg":"错误提交"}');
$dirpath = './img/';//设置文件保存的目录
if(!is_dir($dirpath)){
  //目录不存在则创建目录
  @mkdir($dirpath);
}
$count = count($_files);//所有文件数
if($count<1) die('{"status":0,"msg":"错误提交"}');//没有提交的文件
$success = $failure = 0;
foreach($_files as $key => $value){
  //循环遍历数据
  $tmp = $value['name'];//获取上传文件名
  $tmpname = $value['tmp_name'];//临时文件路径
  //上传的文件会被保存到php临时目录,调用函数将文件复制到指定目录
  if(move_uploaded_file($tmpname,$dirpath.date('ymdhis').'_'.$tmp)){
    $success++;
  }else{
    $failure++;
  }
}
$arr['status'] = 1;
$arr['msg']   = '提交成功';
$arr['success'] = $success;
$arr['failure'] = $failure;
echo json_encode($arr);
  ?>
