效果图
首先看上传图片的工具类,一点都没有少复制就可以用

bos.flush(); bos.close(); return myCaptureFile; } }
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; } }
