如何在不将图像保存到本地的情况下将捕获的图像（表面视图）传递到另一个片段？

Question

我现在有一个来自googlesamples的Camera应用，该应用会捕获图像，然后将其保存到本地存储中。我想要的是将图像转换为位图并将其传递到另一个视图（片段）

public class Camera2BasicFragment extends Fragment

    implements View.OnClickListener, ActivityCompat.OnRequestPermissionsResultCallback {

/**

 * Conversion from screen rotation to JPEG orientation.

 */

private static final SparseIntArray ORIENTATIONS = new SparseIntArray();

private static final int REQUEST_CAMERA_PERMISSION = 1;

private static final String FRAGMENT_DIALOG = "dialog";

static {

    ORIENTATIONS.append(Surface.ROTATION_0, 90);

    ORIENTATIONS.append(Surface.ROTATION_90, 0);

    ORIENTATIONS.append(Surface.ROTATION_180, 270);

    ORIENTATIONS.append(Surface.ROTATION_270, 180);

}

private static final String TAG = "Camera2BasicFragment";

private static final int STATE_PREVIEW = 0;

private static final int STATE_WAITING_LOCK = 1;

private static final int STATE_WAITING_PRECAPTURE = 2;

private static final int STATE_WAITING_NON_PRECAPTURE = 3;

private static final int STATE_PICTURE_TAKEN = 4;

private static final int MAX_PREVIEW_WIDTH = 1920;

private static final int MAX_PREVIEW_HEIGHT = 1080;

private final TextureView.SurfaceTextureListener mSurfaceTextureListener

        = new TextureView.SurfaceTextureListener() {

    @Override

    public void onSurfaceTextureAvailable(SurfaceTexture texture, int width, int height) {

        openCamera(width, height);

    }

    @Override

    public void onSurfaceTextureSizeChanged(SurfaceTexture texture, int width, int height) {

        configureTransform(width, height);

    }

    @Override

    public boolean onSurfaceTextureDestroyed(SurfaceTexture texture) {

        return true;

    }

    @Override

    public void onSurfaceTextureUpdated(SurfaceTexture texture) {

    }

};

private String mCameraId;

private AutoFitTextureView mTextureView;

private CameraCaptureSession mCaptureSession;

private CameraDevice mCameraDevice;

private Size mPreviewSize;

我有一个ViewFragment，我想在其中检索捕获的图像，但是我将如何实现呢？有什么建议吗

Answer 1

您应该暂时保存它，如果尝试使用捆绑包进行转移，则可能会出现事务太大的错误。

Answer 2

例如，您可以使用Bitmap，因为它是Implements Parcelable，所以可以通过bundle传递它。但！这不是解决方案，因为捆绑包的最大大小介于512-1024kb之间因此，我认为最好保存照片，因为它可能会占用大量RAM作为对象，并且在其中收到链接后Fragment，只需删除即可。
