拍照和选择相册照片

1. 相册选择图片

private void setalbumImg(int type2) {
        // TODO Auto-generated method stub
        pw.dismiss();
        // 从相册获取图片
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType(IMAGE_TYPE);
        startActivityForResult(intent, type2);
        // 把资源图片转换成bitmap
        // bm= BitmapFactory.decodeResource(MainActivity.this.getResources(),
        // R.drawable.ic_launcher);
        // img.setImageBitmap(bm);
    }
 

2.拍照

private void setcameraImg(int type2) {
        // TODO Auto-generated method stub
        pw.dismiss();
        Intent intent = new Intent();
        intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, type2+1);
    }

3   onActivityResult：  其中img_shipper表示的是ImgView要显示的那个照片

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            // 外界的程序访问ContentProvider所提供数据 可以通过ContentResolver接口
            ContentResolver resolver = getContentResolver();
            // 此处的用于判断接收的Activity是不是你想要的那个
            if (requestCode == type) {
                try {
                    Uri originalUri = data.getData(); // 获得图片的uri
                    bm = MediaStore.Images.Media.getBitmap(resolver,
                            originalUri);
                    // 图片等比例缩放
                    Bitmap bitmap = CommonUtils.scaleImg(bm,
                            CommonUtils.getViewWIth(img_shipper)[0],
                            CommonUtils.getViewWIth(img_shipper)[1]);
                    // scaleImg();
                    // 显得到bitmap图片
                    // cutImg(originalUri);
                    iconpath = "touxiang.png";

//                    saveImg();
                    img_shipper.setImageBitmap(bitmap);
                } catch (IOException e) {
                    Log.e("TAG-->Error", e.toString());
                }
            }
            if (requestCode ==type+1) {
                Bundle bundle = data.getExtras();
                bm = (Bitmap) bundle.get("data");// 获取相机返回的数据，并转换为Bitmap图片格式
                // 图片等比例缩放
            Bitmap    bitmap=    CommonUtils.scaleImg(bm, CommonUtils.getViewWIth(img_shipper)[0],  CommonUtils.getViewWIth(img_shipper)[1]);
                // scaleImg();

                // 图片剪切
                iconpath = "touxiang.png";

//                Uri uri = Uri.fromFile(fi);
//                cutImg(uri);
                // 显得到bitmap图片
                img_shipper.setImageBitmap(bitmap);
            }
            if (requestCode == 200) {
                // 拿到剪切数据
                bm = data.getParcelableExtra("data");

                // 显示剪切的图像
                // img.setImageBitmap(bm);

            }
        }
    }

                byte[] b = u.send();
                String result = new String(b);
                System.out.println(result);
                Gson gson=new Gson();
                CarUrl carUrl=gson.fromJson(result, CarUrl.class);
