Android Inbuild(ActionImageCapture) 意图返回空意图.无法传递结果 {who= null} [英] Android Inbuild(ActionImageCapture) intent returns null intent .Cannot deliver result {who= null}

问题描述

我使用默认的相机意图在我的应用中获取图像.问题是相机在 onActivityResult() 上返回 null.ResultCode 和 RequestCode 按预期返回.

I am using the default camera intent to get the image in my app. The problem is camera returns null on onActivityResult() . The ResultCode and RequestCode are returning as expected.

我的意图调用是:

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 1224;
....
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

OnactivityResult 是:

OnactivityResult is:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
    //use imageUri here to access the image
    Uri imageuri = data.getData(); // here is getting crash 
    imageView.setImageFromUri(imageUri);
}
}
}

void setImageFromUri(Uri imgUri){
 ... TODO assign image from uri
}

当我放置日志时，我得到了 resultCode 和 responseCode 不为空

As I put Log I got the resultCode and responseCode are not null

resultCode = -1
requestCode = 1224

我哪里做错了?

但是拍摄的图片存储在我指定的路径(imageUri)中

But the taken picture is stored in the path (imageUri) as I specified

有没有其他方法可以使用相机获取图像.

Is there any other way to get image using camera.

推荐答案

看来你在 onActivityResult 之前就知道 imageUri.这不是正确的答案，但可以正常工作.

Seems you know the imageUri before onActivityResult. This is not correct answer but will work fine.

intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); 

//这个图片uri只有你要使用

// This image uri only you're going to use

所以不要使用

 Uri imageuri = data.getData();

只需使用您已知的 uri.

just use the uri you known.

您的代码如下所示:

if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
  if (resultCode == RESULT_OK) {
//use imageUri here to access the image
imageView.setImageFromUri(imageUri); // imageUri should be global in the activity
  }
}
