Question

我的手机是4.2.2。我正在运行android studio

在我的mainActivity上：

startActivityForResult(new CameraStuff().createCustomDialogCamGallery(this,
                getCurrentPhotoPath()), REQUEST_IMAGE_OPTIONS);

我显示自定义对话框的代码是：

public Intent createCustomDialogCamGallery(Activity activity,String fullCameraActivityPath){
        // Camera.
        final List<Intent> cameraIntents = new ArrayList<Intent>();

        if(!checkCam(activity).equals(NO_CAM)) {
            final Intent captureIntent = new Intent(android.provider.MediaStore
                    .ACTION_IMAGE_CAPTURE);
            final PackageManager packageManager = activity.getPackageManager();
            final List<ResolveInfo> listCam = packageManager.queryIntentActivities
                    (captureIntent, 0);
            for (ResolveInfo res : listCam) {
                final String packageName = res.activityInfo.packageName;
                final Intent intent = new Intent(captureIntent);
                intent.setComponent(new ComponentName(res.activityInfo.packageName, res
                        .activityInfo.name));
                intent.setPackage(packageName);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, fullCameraActivityPath);
                cameraIntents.add(intent);
            }
        }


        // Filesystem.
        final Intent galleryIntent = new Intent();
        galleryIntent.setType("image/*");
        galleryIntent.setAction(Intent.ACTION_PICK);

        // Chooser of filesystem options.
        final Intent chooserIntent = Intent.createChooser(galleryIntent, "Foto");

        // Add the camera options.
        if(!checkCam(activity).equals(NO_CAM)) {
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new
                    Parcelable[cameraIntents.size()]));
        }

        return chooserIntent;

打开自定义对话框，其中包含相机和图库选项。当我选择相机并拍摄时：

在使用我的小型Android 4.2.2手机拍摄时，onActivityResult中的data.getData（）得到了null。

在拍摄我的三星Galaxy S4 4.2.2时，我获得了data.getdata（）值。我实现了data.getData（）附带的调试：content：// media / external / images / media / 2846

我该如何解决这个问题？

Answer 1

fullCameraActivityPath必须是URI。我将path参数作为String传递。那就是虫子......

intent.putExtra(MediaStore.EXTRA_OUTPUT, fullCameraActivityPath);

onActivityResult data.getData（）在拍摄相机后返回null
