public void takePic(){
        String forderPath =  getExternalFilesDir("")  + "/pic";
        File file = new File(forderPath);
        if (!file.exists()){
            file.mkdirs();
        }
        String randomNum = DateTools.getCurrentData_yyyyMMddHHmmss();
        //创建File对象，用于存储拍照后的照片
        File outputImage = new File(forderPath,randomNum + "_output_image.jpg");
        currentImagPath = outputImage.getAbsolutePath();

        try {
            if (outputImage.exists()){
                outputImage.delete();
            }
            outputImage.createNewFile();
        }catch (IOException e){
            e.printStackTrace();
        }
        if (Build.VERSION.SDK_INT >= 24){
            imageUri = FileProvider.getUriForFile(context,"xxxxxx.packagename",outputImage);
        }else {
            imageUri = Uri.fromFile(outputImage);
        }
        //启动相机程序
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

        intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);

        startActivityForResult(intent,TAKE_PHOTO);
    }

以上是拍照程序

下面是处理

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        switch (requestCode){
            case TAKE_PHOTO:
                if (resultCode == RESULT_OK){
//                    String mimgUri =  imageUri.toString();
//                    String path = imageUri.getPath();
                    String path  = getProviderUriPath(imageUri);
                    Uri uri = Uri.parse(path);
                    mUploadMessage.onReceiveValue(uri);
                }
                break;
    }    
}

其中getProviderUriPath工具类可以查看我上一篇文章
