ACTION_IMAGE_CAPTURE返回图像文件作为Extra而不是Data

我的应用程序的功能之一包括相机.用户拍照,然后应用程序显示图像.

我使用StartActivityForResult从ACTION_IMAGE_CAPTURE开始意图,并通过onActivityResult捕获响应.通常,我可以简单地在onActivityResult中收到的意图上调用getData()并获取MediaProvider的内容uri.

我的问题如下：我的测试设备之一,华为ALE-L21,我在onActivityResult中获得的意图没有数据,但是,它具有可分解的额外功能.我如何从中获取用户照片？ Android Studio也没有告诉我多余的名称

免责声明：我之所以调用getActivity()是因为我正在片段中使用此代码

这就是我用来获取相机的方法.

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
    startActivityForResult(takePictureIntent, getResources().getInteger(R.integer.RQ_PERMISSION_WRITE_EXTERNAL_STORAGE));
}

这是我的onActivityResult中的代码

@Override
public void onActivityResult(int requestCode, int resultCode, Intent resultIntent) {
    super.onActivityResult(requestCode, resultCode, resultIntent);

    switch (requestCode) {
        case 1: //RQ_ImageCapture
        case 2: //RQ_ImageSelected
            if (resultIntent != null) {
                try {
                    Uri selectedImage = resultIntent.getData();
                    if(selectedImage != null) {
                        Bitmap bitmap = 
                        MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), selectedImage);
                        setImageAsBackground(selectedImage, bitmap);
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            break;
    }
}

解决方法:

Usually I can simply call getData() on the intent I receive in onActivityResult and get the content uri for the MediaProvider.

您的代码将无法在其中许多代码上使用,包括所有最新的Nexus设备. ACTION_IMAGE_CAPTURE不应该返回Uri.引用the documentation：

If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT.

由于不包括EXTRA_OUTPUT,因此将获得带有缩略图的额外数据(getData().getExtra(“ data”)).

the intent I get in onActivityResult has no data, but instead, it has a parcellable extra

给定您的ACTION_IMAGE_CAPTURE请求,这就是您应该得到的.

如果需要全尺寸的图像,请包括EXTRA_OUTPUT,也许指向应用程序中的FileProvider,例如我在this sample app中演示的那样.然后,您就知道应该将照片放到哪里的Uri,因为您指定了Uri.
