SurfaceView 上的 Android 相机肖像并保存快照

Question

我的api是2.2，所以我使用camera.setDisplayOrientation(90)来使预览为纵向，这个效果很好，但是当我将图片保存到sd时，图片是水平的而不是纵向。当我使用时：

@Override
    protected Bitmap doInBackground(String... params) {

        int w = bmp.getWidth();
        int h = bmp.getHeight();
        // Setting post rotate to 90
        Matrix mtx = new Matrix();
        mtx.postRotate(90);
        // Rotating Bitmap
        Bitmap rotatedBMP = Bitmap.createBitmap(bmp, 0, 0, w, h, mtx, true);
        bmp.recycle();
        return rotatedBMP;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        dialog.dismiss();

        ivNewPhoto.setImageBitmap(result);
        resultPath = ConstValue.MY_ALBUM_DIR + "/" + System.currentTimeMillis() + ".jpg";
        ImageFile.writePhotoJpg(result), resultPath);
        previewView.setVisibility(View.VISIBLE);
    }

bmp是快照图片但我有错误：

Activity com.android.SuperPictureSearch.photo.PhotoActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@43abb200 that was originally added here

你能告诉我如何保存图片为肖像，谢谢

Answer 1

 public void onPictureTaken(byte[] data, Camera camera) {

          Bitmap mutableBitmap = null;
          BitmapFactory.Options options = new BitmapFactory.Options();
          Bitmap  bm= BitmapFactory.decodeByteArray(data, 0, data.length, options);
           mutableBitmap =Bitmap.createScaledBitmap( bm , h, w,true);
             bm.recycle();
                Matrix matri = new Matrix();
                matri.postRotate(90);

                Bitmap  mBitmap = Bitmap.createBitmap(mutableBitmap, 0, 0, mutableBitmap.getWidth(), mutableBitmap.getHeight(), matri, true);
                mutableBitmap.recycle();

因为照片对于相机来说太大了，所以我调整了尺寸
