从相册获取图片的方法

/**
 * 从相册选择图片来源
 */
private void getphoto() {
 intent intent = new intent(intent.action_pick, android.provider.mediastore.images.media.external_content_uri);
 intent.setdataandtype(mediastore.images.media.external_content_uri,
  "image/*");
 startactivityforresult(intent, photo_request);
}

从系统相机拍照获取照片

/**
 * 从系统相机选择图片来源
 */
private void getcamera() {
 intent intent = new intent(mediastore.action_image_capture);

 // 下面这句指定调用相机拍照后的照片存储的路径
 intent.putextra(mediastore.extra_output, uri.fromfile(new file(
  environment.getexternalstoragedirectory(), "hand.jpg")));
 startactivityforresult(intent, camera_request);
}

调用系统裁剪工具裁剪图片

/****
 * 调用系统自带切图工具对图片进行裁剪
 * 微信也是
 *
 * @param uri
 */
private void photoclip(uri uri) {
 // 调用系统中自带的图片剪裁
 intent intent = new intent("com.android.camera.action.crop");
 intent.setdataandtype(uri, "image/*");
 // 下面这个crop=true是设置在开启的intent中设置显示的view可裁剪
 intent.putextra("crop", "true");
 // aspectx aspecty 是宽高的比例
 intent.putextra("aspectx", 1);
 intent.putextra("aspecty", 1);
 // outputx outputy 是裁剪图片宽高
 intent.putextra("outputx", 150);
 intent.putextra("outputy", 150);
 intent.putextra("return-data", true);
 startactivityforresult(intent, photo_clip);
}

上传服务器的方法

/**
 * 上传图片到服务器
 */
private void touploadfile() {
 pd = progressdialog.show(this, "", "正在上传文件...");
 pd.show();
 string filekey = "avatarfile";
 uploadutil uploadutil = uploadutil.getinstance();
 uploadutil.setonuploadprocesslistener(mainactivity.this); //设置监听器监听上传状态

 map<string, string> params = new hashmap<string, string>();//上传map对象
 params.put("userid", "");
 uploadutil.uploadfile(filepath, filekey, "上传头像的地址", params);
 toast.maketext(this, "上传成功", toast.length_long).show();
}

重新服务器响应方法

/**
 * 上传服务器响应回调
 */
@override
public void onuploaddone(int responsecode, string message) {
 //上传完成响应
 pd.dismiss();
 message msg = message.obtain();
 msg.what = upload_file_done;
 msg.arg1 = responsecode;
 msg.obj = message;
}

@override
public void onuploadprocess(int uploadsize) {
 //上传中
 message msg = message.obtain();
 msg.what = upload_in_process;
 msg.arg1 = uploadsize;
}

@override
public void initupload(int filesize) {
 //准备上传
 message msg = message.obtain();
 msg.what = upload_init_process;
 msg.arg1 = filesize;
}

重写这些方法需要实现接口

public class mainactivity extends appcompatactivity implements view.onclicklistener, uploadutil.onuploadprocesslistener {

重写onactivityresult获取数据

@override
protected void onactivityresult(int requestcode, int resultcode, intent data) {
 super.onactivityresult(requestcode, resultcode, data);
 switch (requestcode) {
 case camera_request:
  switch (resultcode) {
  case -1://-1表示拍照成功
   file file = new file(environment.getexternalstoragedirectory()
    + "/hand.jpg");//保存图片
   if (file.exists()) {
   //对相机拍照照片进行裁剪
   photoclip(uri.fromfile(file));
   }
  }
  break;

 case photo_request://从相册取
  if (data != null) {
  uri uri = data.getdata();
  //对相册取出照片进行裁剪
  photoclip(uri);

  }
  break;
 case photo_clip:
  //完成
  if (data != null) {

  bundle extras = data.getextras();
  if (extras != null) {
   bitmap photo = extras.getparcelable("data");
   try {
   //获得图片路径
   filepath = uploadutil.savefile(photo, environment.getexternalstoragedirectory().tostring(), "hand.jpg");
   //上传照片
   touploadfile();
   } catch (ioexception e) {
   e.printstacktrace();
   }
   //上传完成将照片写入imageview与用户进行交互
   mimageview.setimagebitmap(photo);
  }
  }
  break;
 }
}
