相机意图未添加额外内容 [英] Camera Intent Not Adding Extra
问题描述
我正在使用隐式意图拍照.我一直在遵循教程中概述的工作.我遇到的问题是没有添加到Intent的额外内容.这是我正在使用的代码:
I am using an implicit Intent to take a picture. I have been following the work outlined in this tutorial. The issue that I am having is that the extra added to the Intent is not being delivered. Here is the code I'm using:
private void dispatchTakePictureIntent(Context context) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(context.getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile(this.getActivity());
} catch (IOException ex) {
Log.e(TAG, "Error creating file: " + ex.toString());
//TODO: 2017/1/24 - Handle file not created
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setTitle("Error")
.setMessage(ex.toString());
final AlertDialog dialog = builder.create();
dialog.show();
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(context,
"com.example.myapp",
photoFile);
//THIS EXTRA IS NOT BEING ADDED TO THE INTENT
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
galleryAddPic(context, photoFile.getAbsolutePath());
}
}
}
当触发onActivityResult
方法时,Intent
为空.这是代码:
When the onActivityResult
method is fired, the Intent
is empty. Here is that code:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
//These extras are empty. I have used the debug tool, and there is nothing in here.
Bundle extras = data.getExtras();
//extras is null
imageBitmap = (Bitmap) extras.get("data");
previewImage.setImageBitmap(imageBitmap);
}
}

推荐答案
为什么意图是空的?
Why is the intent empty?
通过在ACTION_IMAGE_CAPTURE
请求中包含EXTRA_OUTPUT
来要求将其为空.引用文档:
Because you asked for it to be empty, by including EXTRA_OUTPUT
in your ACTION_IMAGE_CAPTURE
request. Quoting the documentation:
调用方可以传递一个额外的EXTRA_OUTPUT来控制将图像写入何处.如果不存在EXTRA_OUTPUT,则会在Extra字段中将一个小型图像作为Bitmap对象返回.这对于只需要较小图像的应用程序很有用.如果存在EXTRA_OUTPUT,则将全尺寸图像写入EXTRA_OUTPUT的Uri值.
The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. 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.
我该怎么做才能解决此问题?
What do I need to do to fix this issue?
要么:
-
摆脱
EXTRA_OUTPUT
(如果您想要缩略图大小的图像),或者
Get rid of
EXTRA_OUTPUT
(if you want a thumbnail-sized image), or
停止寻找"data"
附加内容,并查看在EXTRA_OUTPUT
Stop looking for the "data"
extra, and look in the location that you specified in EXTRA_OUTPUT
