                // 从文件中创建uri
                imageUri = Uri.fromFile(tempFile);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

//                    //申请WRITE_EXTERNAL_STORAGE权限

                imageUri = activity.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            }
        }
        // 开启一个带有返回值的Activity，请求码为PHOTO_REQUEST_CAREMA
        activity.startActivityForResult(intent, PHOTO_REQUEST_CAREMA);
    }

    /*
* 判断sdcard是否被挂载
*/
    public static boolean hasSdcard() {
        return Environment.getExternalStorageState().equals(
                Environment.MEDIA_MOUNTED);
    }
}

调用方法：

photoActivity.openCamera(this);

记得添加读写权限和注册activity。
