CameraX ImageView 不会显示拍摄的图像

如何解决CameraX ImageView 不会显示拍摄的图像

我有两个片段：

Fragment CameraXPicture

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:background="#FF000000"
tools:context=".pkgActivity.Cameraimp">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.camera.view.PreviewView
        android:id="@+id/camera"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:contentDescription="@string/preview_area"
        android:importantForAccessibility="no">


    </androidx.camera.view.PreviewView>
    <ImageView
        android:id="@+id/captureImg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:contentDescription="@string/capture"
        android:src="@mipmap/ic_launcher" />
 </RelativeLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

PictureCropp

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".pkgActivity.FragmentCroppImage">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    //hardcoded for testing reasons
    <ImageView
        android:id="@+id/takenPicture"
        android:layout_width="200dp" 
        android:layout_height="200dp" />

</LinearLayout>

我的 CameraXPicture Fragment 拍摄一张照片并将照片转发给 FragmentimageCropp：

private Executor executor = Executors.newSingleThreadExecutor();
captureImage.setonClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        imageCapture.takePicture(executor,new ImageCapture.OnImageCapturedCallback() {
            @SuppressLint("UnsafeExperimentalUsageError")
            @Override
            public void onCaptureSuccess(@NonNull ImageProxy image) {

                FragmentCroppImage fragment2 = new FragmentCroppImage();
                Bundle args = new Bundle();
                args.putByteArray("takenPic",imageProxyToBitmapByteArray(image));// length returns 6489014
                fragment2.setArguments(args);

                FragmentManager fragmentManager =  getFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                fragmentTransaction.addToBackStack(null);
                fragmentTransaction.replace(R.id.frameLHaupt,fragment2);
                fragmentTransaction.commit();

            }

            @Override
            public void onError(@NonNull ImageCaptureException exception) {
                exception.printstacktrace();
            }
        });
    }
});



private byte[] imageProxyToBitmapByteArray(ImageProxy image) {
    ImageProxy.PlaneProxy planeProxy = image.getPlanes()[0];
    ByteBuffer buffer = planeProxy.getBuffer();

    byte[] bytes = new byte[buffer.remaining()];
    return bytes;
}

我的 FragmentimageCropp 只有显示图像的工作：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_ParaM1);
        mParam2 = getArguments().getString(ARG_ParaM2);
        bitmapAsArray = getArguments().getByteArray("takenPic");

        Log.e("received length",""+bitmapAsArray.length); //receives 6489014
    }
}

ImageView takenPicture;
byte[] bitmapAsArray = new byte[3]; //testvalue
@Override
public void onViewCreated(View view,@Nullable Bundle savedInstanceState) {
    takenPicture = view.findViewById(R.id.takenPicture);
    takenPicture.setimageBitmap(BitmapFactory.decodeByteArray(bitmapAsArray,bitmapAsArray.length));
}

问题是 ImageView 不会显示图像。 ImageView 保持“空”。

问题是我不知道问题可能是什么。是将图片转换为bytearray 还是因为bytearray 转换为bitmap 导致图片出错？

我使用 bytearray 的原因是传输对象（代理图像）需要更长的时间，我想尽可能防止长时间的延迟。

编辑 似乎转换本身不是问题吧知道。我尝试显示硬编码的图片，但没有显示
