摄影机意图未返回片段未调用活动结果

Question

我试图打开相机拍摄图像，存储在字节数组中，然后在片段上显示图像。

相机正在打开并拍摄照片，但是当您单击勾号时，它只会再次显示相机。

我检查了活动结果，但未调用它。 我具有所有正确的权限设置。

我在这里尝试了其他答案，但没有成功。

这是我打开片段中的相机的方法：

@AfterPermissionGranted(REQUEST_PERMISSIONS_ACTIVITY_REQUEST_CODE)
private void openCamera(){
    // start main activity
    String [] perms = {Manifest.permission.CAMERA};
    if (EasyPermissions.hasPermissions(getActivity(), perms)){

        // Start the Camera
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

    } else {
        Log.d("Chex ", "Check did not find permissions starting dialog to explain use of user permissions");
        EasyPermissions.requestPermissions(this, "This app needs camera permissions to store reciepts", REQUEST_PERMISSIONS_ACTIVITY_REQUEST_CODE, perms);
    }
}

这是片段中的onActivityResult：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.d("Chex ", "On activity results called " + resultCode);

    if (resultCode == AppSettingsDialog.DEFAULT_SETTINGS_REQ_CODE){
        openCamera();
    } else{
        openCamera();
    }

    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
        if (resultCode == Activity.RESULT_OK) {
            Bitmap bmp = (Bitmap) data.getExtras().get("data");
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
            transactionImageLocationByteArray = stream.toByteArray();

            // Load the image into the imageview
            Glide.with(getActivity()).asBitmap().load(transactionImageLocationByteArray).into(addTransactionCameraButon);

        } else if (resultCode == Activity.RESULT_CANCELED) {
            Toast.makeText(getActivity(), "Image Capture Cancelled", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(getActivity(), "Image Capture Failed", Toast.LENGTH_SHORT).show();
        }
    }
} 

编辑：
在requestPermission上添加：

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    Log.d("Chex ", "Permission on request result came back with " + grantResults);
    EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}

编辑2：
将onActivityResult添加到了主活动（该片段的主机活动）中，但没有更改：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

Answer 1

如果您正在片段中调用openCamera方法，则需要检查一下

片段中未调用onActivityResult

Answer 2

从onActivityResult()移除super 。

删除这一行super.onActivityResult(requestCode, resultCode, data);

super将继承父类onActivityResult

Answer 3

您需要更改onActivityResult（）：

   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == AppSettingsDialog.DEFAULT_SETTINGS_REQ_CODE) {
            // Do something after user returned from app settings screen
            openCamera();
        } else if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

            if (resultCode == Activity.RESULT_OK) {
                Bitmap bmp = (Bitmap) data.getExtras().get("data");
                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
                transactionImageLocationByteArray = stream.toByteArray();

                // Load the image into the imageview
                Glide.with(getActivity()).asBitmap().load(transactionImageLocationByteArray).into(addTransactionCameraButon);

            } else if (resultCode == Activity.RESULT_CANCELED) {
                Toast.makeText(getActivity(), "Image Capture Cancelled", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getActivity(), "Image Capture Failed", Toast.LENGTH_SHORT).show();
            }
        }
    }

编辑：将以下代码添加到您的Activity的onActivityResult()方法中。

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.yourFragmentId);
        fragment.onActivityResult(requestCode, resultCode, data);

}
