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; } }
