Camera Intent自动裁剪卡IO？或显示表面（虚线）和自动裁剪捕获后

Question

我正在使用Camera Intent捕获和上传..对于默认摄像头

所以在这里，我跟着this裁剪图像就像卡片IO ..

但上面的一个是单独的相机而不是意图

我希望表面固定器应放在相机意图内..如果可以，任何人都可以建议我......

我希望这个表面裁剪在捕捉之前....仅用于相机意图..不适用于画廊......就像卡片IO ......但仅适用于作物......不是OCR ..

所以我想在这个

中使用上述功能

private File createImageFile() throws IOException {
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    File imageFile = File.createTempFile(imageFileName,".jpg",storageDir);
    return imageFile;
}
public class PQChromeClient extends WebChromeClient {

public boolean onShowFileChooser(WebView view, ValueCallback<Uri[]> filePath, WebChromeClient.FileChooserParams fileChooserParams) {
        if (mFilePathCallback != null) {
            mFilePathCallback.onReceiveValue(null);
        }
        mFilePathCallback = filePath;

        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            File photoFile = null;
            try {
                photoFile = createImageFile();
                takePictureIntent.putExtra("PhotoPath", mCameraPhotoPath);
            } catch (IOException ex) {
                Log.e(TAG, "Unable to create Image File", ex);
            }
            if (photoFile != null) {
                mCameraPhotoPath = "file:" + photoFile.getAbsolutePath();
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photoFile));
            } else {
                takePictureIntent = null;
            }
        }
        Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
        contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
        contentSelectionIntent.setType("image*//*");
        Intent[] intentArray;
        if (takePictureIntent != null) {
            intentArray = new Intent[]{takePictureIntent};
        } else {
            intentArray = new Intent[0];
        }

        Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
        //chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
        chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
        chooserIntent.putExtra(Intent.EXTRA_TITLE, "Image Chooser");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
        //chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
        startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);
        return true;
    }

    public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {
        mUploadMessage = uploadMsg;
        File imageStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "My_Camera");

        if (!imageStorageDir.exists()) {
            imageStorageDir.mkdirs();
        }
        File file = new File(imageStorageDir + File.separator + "IMG_"+ String.valueOf(System.currentTimeMillis())+ ".jpg");

        mCapturedImageURI = Uri.fromFile(file);
        final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

        captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);

        Intent i = new Intent(Intent.ACTION_GET_CONTENT);
        i.addCategory(Intent.CATEGORY_OPENABLE);
        i.setType("image*//*");

        Intent chooserIntent = Intent.createChooser(i,"Image Chooser");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Parcelable[] { captureIntent });
        startActivityForResult(chooserIntent, FILECHOOSER_RESULTCODE);
    }

    public void openFileChooser(ValueCallback<Uri> uploadMsg) {
        openFileChooser(uploadMsg, "");
    }

    public void openFileChooser(ValueCallback<Uri> uploadMsg,String acceptType,String capture) {
        openFileChooser(uploadMsg, acceptType);
    }
}

可能有人建议我......关于这个...

在这里，我尝试使用自动裁剪，通过放置裁剪的意图...但它显示预览像表面从哪里到它的裁剪....对于默认相机通过意图.....不适用于自定义相机活动。 ..
