如何在没有意图的情况下从相机拍摄照片 [英] How to capture a photo from the camera without intent

问题描述

我希望我的应用能够在不使用其他应用的情况下拍摄照片.我使用的代码:

I want my app to be able to capture photos without using another application. The code i used :

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File photo = null;
    try
    {
        photo = this.createTemporaryFile("picture", ".jpg");
        photo.delete();
    }
    catch(Exception e)
    {
        Toast.makeText(getApplicationContext(),"Error",Toast.LENGTH_LONG).show();

    }
    mImageUri = Uri.fromFile(photo);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
    startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

但此代码使用手机的主摄像头应用.谁能给我一些代码?

But this code uses the phone's main camera app. Can anyone give me some code ?

推荐答案

直接使用 Camera 类拍照非常复杂.

Taking a picture directly using the Camera class is insanely complicated to get right.

我正在开发一个简化此操作的库，您只需添加一个 CameraFragment 到您的应用程序的基本预览 UI，并在其上调用 takePicture() 以拍摄照片，并通过各种方式配置行为(例如，保存图片的位置).但是，这个库仍在进行中.

I am working on a library to simplify this, where you just add a CameraFragment to your app for the basic preview UI, and call takePicture() on it to take a picture, with various ways to configure the behavior (e.g., where the pictures get saved). However, this library is still a work in progress.

谁能给我一些代码?

某些代码"将长达数千行(对于完整的实现，包括处理各种特定于设备的怪事).

"Some code" is going to be thousands of lines long (for a complete implementation, including dealing with various device-specific oddities).
