Activity 中的代码，我只贴出重要的事件部分代码
public void doPhoto(View view)
{
destoryBimap();
String state = Environment.getExternalStorageState();
if (state.equals(Environment.MEDIA_MOUNTED)) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

} else {
Toast.makeText(MainActivity.this, "没有SD卡", Toast.LENGTH_LONG).show();
}
}

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{

}

if (bundle != null) {
this.photo = (Bitmap) bundle.get("data");
} else {
Toast.makeText(MainActivity.this, "拍照失败", Toast.LENGTH_LONG).show();
return;
}
}
FileOutputStream fileOutputStream = null;
try {
// 获取 SD 卡根目录

// 新建目录

// 生成文件名

// 新建文件
File file = new File(saveDir, filename);
// 打开文件输出流

// 生成图片文件
this.photo.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);
// 相片的完整路径
this.picPath = file.getPath();
ImageView imageView = (ImageView) findViewById(R.id.showPhoto);
imageView.setImageBitmap(this.photo);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (fileOutputStream != null) {
try {
fileOutputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
/**

其中的上传工具类我们下面一起来看：
Android 发送HTTP GET POST 请求以及通过 MultipartEntityBuilder 上传文件
全部使用新的方式 MultipartEntityBuilder 来处理了。

在 Activity 中的使用方法（这里我还是只写主体部分代码）：

public void doClick(View view)

get
.setCharset(HTTP.UTF_8)
.setConnectionTimeout(5000)
.setSoTimeout(5000);
get.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() {
@Override
public void onRequest(ZHttpRequest request) throws Exception {
}
@Override
public String onSucceed(int statusCode, ZHttpRequest request) throws Exception {
return request.getInputStream();
}
@Override
public String onFailed(int statusCode, ZHttpRequest request) throws Exception {
return "GET 请求失败：statusCode "+ statusCode;
}
});
ZHttpRequest post = new ZHttpRequest();
post
.setCharset(HTTP.UTF_8)
.setConnectionTimeout(5000)
.setSoTimeout(10000);
post.setOnHttpRequestListener(new ZHttpRequest.OnHttpRequestListener() {
private String CHARSET = HTTP.UTF_8;
private ContentType TEXT_PLAIN = ContentType.create("text/plain", Charset.forName(CHARSET));
@Override
public void onRequest(ZHttpRequest request) throws Exception {
// 设置发送请求的 header 信息
request.addHeader("cookie", "abc=123;456=爱就是幸福;");
// 配置要 POST 的数据
MultipartEntityBuilder builder = request.getMultipartEntityBuilder();
builder.addTextBody("p1", "abc");
builder.addTextBody("p2", "中文", TEXT_PLAIN);
builder.addTextBody("p3", "abc中文cba", TEXT_PLAIN);
if (picPath != null && ! "".equals(picPath)) {
builder.addTextBody("pic", picPath);
builder.addBinaryBody("file", new File(picPath));
}
request.buildPostEntity();
}
@Override
public String onSucceed(int statusCode, ZHttpRequest request) throws Exception {
return request.getInputStream();
}
@Override
public String onFailed(int statusCode, ZHttpRequest request) throws Exception {
return "POST 请求失败：statusCode "+ statusCode;
}
});
TextView textView = (TextView) findViewById(R.id.showContent);
String content = "初始内容";
try {
if (view.getId() == R.id.doGet) {
content = get.get("http://www.baidu.com");
content = "GET数据：isGet: " + (get.isGet() ? "yes" : "no") + " =>" + content;
} else {
content = post.post("http://192.168.1.6/test.php");
content = "POST数据：isPost" + (post.isPost() ? "yes" : "no") + " =>" + content;
}
} catch (IOException e) {
content = "IO异常：" + e.getMessage();
} catch (Exception e) {
content = "异常：" + e.getMessage();
}
textView.setText(content);
}
其中 picPath 为 SD 卡中的图片路径 String 类型，我是直接拍照后进行上传用的

至于服务端我用的 PHP ，只是简单的输出获取到的数据而已
<?php
echo 'GET:<br>'. "\n";
//print_r(array_map('urldecode', $_GET));
print_r($_GET);
echo '<br>'. "\n". 'POST:<br>'. "\n";
//print_r(array_map('urldecode', $_POST));
print_r($_POST);
echo '<br>'. "\n". 'FILES:<br>'. "\n";
print_r($_FILES);
echo '<br>'. "\n". 'COOKIES:<br>'. "\n";
print_r($_COOKIE);
