相机意图数据在三星 S3 中的 onActivityResult(int requestCode， int result

Question

问题：我在三星 S3 的onActivityResult(int requestCode, int resultCode, Intent data)中获取相机意图的数据为空。但是在其他一些设备上运行良好。我自定义了用于获取数据的代码，并在 Web 中搜索了此问题，但没有发现任何有用的内容。

法典：

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == TAKE_CAMERA && data != null && data.getData() != null)  
           else if (requestCode == TAKE_CAMERA) {
        if (resultCode != RESULT_OK) return;
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setDataAndType(tempFileUri, "image/*");
        intent.putExtra("outputX", 90);
        intent.putExtra("outputY", 90);
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("scale", true);
        intent.putExtra("return-data", true);
        startActivityForResult(intent, CROP_CAMERA);
    } else if (requestCode == CROP_CAMERA && data != null) {
        Bitmap photo = data.getExtras().getParcelable("data");
        try {
            FileOutputStream out = new FileOutputStream(tempFileUri.getPath());
            photo.compress(Bitmap.CompressFormat.JPEG, 90, out);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if (photo != null) {
            imagePhoto.setImageBitmap(photo);
            <my code>
        }
    }

Answer 1

如果您提供MediaStore.EXTRA_OUTPUT，则意图为空，但您将在提供的文件中拥有照片（Uri.fromFile（f））。

在调用捕获的图像时编写以下代码：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_FROM_CAMERA);

并通过以下方式在OnActivityResult（）方法中获取您的URI：

if (resultCode != RESULT_OK)
            return;
        switch (requestCode) {
        case PICK_FROM_CAMERA:
            Log.i("TAG", "Inside PICK_FROM_CAMERA");

            // Describe the columns you'd like to have returned. Selecting from
            // the Thumbnails location gives you both the Thumbnail Image ID, as
            // well as the original image ID
            try {
                Log.i("TAG", "inside Samsung Phones");
                String[] projection = {
                        MediaStore.Images.Thumbnails._ID, // The columns we want
                        MediaStore.Images.Thumbnails.IMAGE_ID,
                        MediaStore.Images.Thumbnails.KIND,
                        MediaStore.Images.Thumbnails.DATA };
                String selection = MediaStore.Images.Thumbnails.KIND + "=" + // Select
                                                                                // only
                                                                                // mini's
                        MediaStore.Images.Thumbnails.MINI_KIND;
                String sort = MediaStore.Images.Thumbnails._ID + " DESC";
                // At the moment, this is a bit of a hack, as I'm returning ALL
                // images, and just taking the latest one. There is a better way
                // to
                // narrow this down I think with a WHERE clause which is
                // currently
                // the selection variable
                Cursor myCursor = this.managedQuery(
                        MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                        projection, selection, null, sort);
                long imageId = 0l;
                long thumbnailImageId = 0l;
                String thumbnailPath = "";
                try {
                    myCursor.moveToFirst();
                    imageId = myCursor
                            .getLong(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
                    thumbnailImageId = myCursor
                            .getLong(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
                    thumbnailPath = myCursor
                            .getString(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
                } finally {
                    // myCursor.close();
                }
                // Create new Cursor to obtain the file Path for the large image
                String[] largeFileProjection = {
                        MediaStore.Images.ImageColumns._ID,
                        MediaStore.Images.ImageColumns.DATA };
                String largeFileSort = MediaStore.Images.ImageColumns._ID
                        + " DESC";
                myCursor = this.managedQuery(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        largeFileProjection, null, null, largeFileSort);
                String largeImagePath = "";
                try {
                    myCursor.moveToFirst();
                    // This will actually give yo uthe file path location of the
                    // image.
                    largeImagePath = myCursor
                            .getString(myCursor
                                    .getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
                    mImageCaptureUri = Uri.fromFile(new File(
                            largeImagePath));
                } finally {
                    // myCursor.close();
                }
                // These are the two URI's you'll be interested in. They give
                // you a
                // handle to the actual images

                // I've left out the remaining code, as all I do is assign the

Answer 3

我通过告诉相机活动将图像保存在SD卡上来解决此问题：

tempImageNameUri = "some temporary name";
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT,tempImageNameUri);
i.putExtra("return-data", true);
startActivityForResult(i,SOME_CONSTANT);

当被调用的活动完成后，onActivityResult从临时路径中取出 SD 卡中的项目并使用它。

您可能已经找到了问题的解决方案，但这会对某人有所帮助。下面是Commonsware创建的博客链接，该链接是关于拍摄照片后图像裁剪的。他说，使用动作com.android.camera.action.CROP可能无法在所有不同类型的设备中完美运行。
