使用Android中的摄像头活动 [英] Using the camera activity in Android

问题描述

如果你想使用内置的，它使用了原生的Andr​​oid摄像头摄像头的活动，只要做到以下几点。

If you want to use the built-in camera activity which uses the native Android camera, simply do the following.

Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);   
        this.startActivityForResult(camera, PICTURE_RESULT);

您想从你显示的漂亮的相机获得的图像回来 - 但如何

You want to get the images back from the nifty camera you displayed -- but how?

推荐答案

如果你想获得的图像放回盛开，传递的URI EXTRA_OUTPUT额外内的意向。如果你没事了短小的位图（你应该是），只需要调用的意图是正常的。

If you want to get the image back in its full glory, pass in a uri to the Intent within the EXTRA_OUTPUT extra. If you're fine with a smallish bitmap (and you should be), just call the intent as normal.

现在你有两个选择，处理图像在EXTRA_OUTPUT额外返回的URI，或做你onActivityResult方法如下：

Now you have two options, deal with the uri of the image that is returned in the EXTRA_OUTPUT extra, or do the following in your onActivityResult method:

if (requestCode == PICTURE_RESULT) //
             if (resultCode == Activity.RESULT_OK) {
                // Display image received on the view
                 Bundle b = data.getExtras(); // Kept as a Bundle to check for other things in my actual code
                 Bitmap pic = (Bitmap) b.get("data");

                 if (pic != null) { // Display your image in an ImageView in your layout (if you want to test it)
                     pictureHolder = (ImageView) this.findViewById(R.id.IMAGE);
                     pictureHolder.setImageBitmap(pic);
                     pictureHolder.invalidate();
                 }
             }
             else if (resultCode == Activity.RESULT_CANCELED) {...}
    }

和你去那里！
