android - 如何从相机获取完整尺寸的位图？

我曾打算发射照相机

Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
getParent().startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

和使用的onActivityResult（）

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
Save_to_SD (thumbnail, filename);

但是get thumbnail的大小很小，如何获取完整的位图？

最佳答案

将输出保存到某个uri并从那里获取

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                mImageCaptureUri1 = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
                        "tmp_avatar_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));

                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri1);
                cameraIntent.putExtra("return-data", true);
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
