人脸检测错误

Question

I'am doing facedetection with the following java code as part of my project.iam getting a strange error

BitmapFactory.Options BitmapFactoryOptionsbfo = new BitmapFactory.Options();

         /*BitMapFactory-Creates Bitmap objects from various sources, including 
          * files, streams, and byte-arrays. 
          */

         BitmapFactoryOptionsbfo.inPreferredConfig = Bitmap.Config.RGB_565; 

imageWidth = myBitmap.getWidth();

     imageHeight = myBitmap.getHeight();

    myFace = new FaceDetector.Face[numberOfFace];

    myFaceDetect = new FaceDetector(imageWidth, imageHeight, numberOfFace);

     numberOfFaceDetected = myFaceDetect.findFaces(myBitmap, myFace); 

     }

//i get error over there in R.drawable.pics      
myBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pics, BitmapFactoryOptionsbfo);

I am supposed to give the name of the pic file in pics but it keeps giving me an error pics cannot be resolved or is not a field. So I set the name of the pic file as pic PS it's a jpg file in the drawable folder. I also named the file within single quotes as 'pic' ---it gives me Invalid character constant error.

I also named it within double quotes but it still doesn't work. I also named it 'pic.jpg' still doesn't work

Answer 1

Possibly there is another variable in your code named 'pics'.

Try saving it in a different folder, say MyPics. And name the picture differently, say xyz1.jpg

In this case write the line as:

myBitmap = BitmapFactory.decodeResource(getResources(), R.MyPics.xyz1, BitmapFactoryOptionsbfo);

Also, did you initialise 'myBitmap' as a bitmap image? Meaning, did you include the line:

Bitmap myBitmap;

in your code, before performing the image read?

Answer 2

Just check with following line of code:

 BitmapFactory.Options options = new BitmapFactory.Options();
 options.inPreferredConfig =  Bitmap.Config RGB_565;
 Bitmap bMap = BitmapFactory.decodeResource(getResources(), R.drawable.icon,options);

Let me know whether it works or not? Also check image names which appears after you type R.drawable.

EDIT:

If still you are not able to access image from drawable, copy your image say pic.png to asset folder and access it using following code:

Updated Code:

try {
       InputStream bitmap=getAssets().open("icon.png");
       Bitmap bit=BitmapFactory.decodeStream(bitmap);
       img.setImageBitmap(bit);
     } catch (IOException e1) {
       // TODO Auto-generated catch block
       e1.printStackTrace();
     }
