mục đích máy ảnh và hàng đợi ưu tiên trong Android

2013-06-08 42 views

Tôi hiện đang viết một ứng dụng Android (API cấp 2.3.3) liên quan đến việc lấy 300 giá trị thang độ xám cao nhất từ ​​ảnh chụp qua mục đích máy ảnh. Sau đây, các hàm (chủ yếu là toán và một số lịch/đồng hồ) được thực hiện trên giá trị kết quả. Tôi đang sử dụng máy ảnh mô phỏng Eclipse /.mục đích máy ảnh và hàng đợi ưu tiên trong Android

Máy ảnh sẽ kích hoạt và ảnh được chụp mà không gặp sự cố, đó là khi tôi cố gắng lưu ảnh (và khi sắp xếp pixel và chức năng toán học/lịch), ứng dụng gặp sự cố.

Tôi đã thử nghiệm ứng dụng chỉ với ý định máy ảnh và giá trị 'giả' cho biến chính (Y) và điều này hoạt động tốt.

Điều gì đang xảy ra?

Dưới đây là phần có liên quan của mã:

int[] pixels; 


    Button button = (Button) findViewById(R.id.button); 

    button.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      String _path = Environment.getExternalStorageDirectory() + File.separator + "sunpic.jpg"; 
      File file = new File(_path); 
      Uri outputFileUri = Uri.fromFile(file); 
      Intent intent = new Intent(
      android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
      intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
      startActivityForResult(intent, 1); 

      } 

    }); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
     switch(requestCode) { 
      case (1): { 
       if (resultCode == RESULT_OK) { 
        Uri outputFileUri = data.getData(); 
        try { 
         Bitmap bmp = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), outputFileUri); 
         bmp.getPixels(pixels, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight()); 

         for(int x = 0; x < bmp.getWidth(); ++x) { 
          for(int y = 0; y < bmp.getHeight(); ++y) { 
           int index = y * bmp.getWidth() + x; 
           int R = (pixels[index] >> 16) & 0xff; 
           int G = (pixels[index] >> 8) & 0xff; 
           int B = pixels[index] & 0xff; 
           Double Grey = (0.299 * R + 0.587 * G + 0.114 * B); 

           int topSize = 300; 
           // priority queue to save the largest topSize values 
           PriorityQueue<Double> pq; 
           pq = new PriorityQueue<Double>(topSize+1); 

           double nv = Grey.floatValue(); 
           if (pq.size() < topSize || pq.peek() < nv) { 
            // remove the smallest value from the queue only if it is full 
            if (pq.size() == topSize) { 
             pq.poll(); 
            } 
            pq.add(nv); 
           } 
           double sum = 0; 
           for(Double d : pq) { 
            sum += d; 

           } 
           double Y = sum/300;

Trong Manifest XML, tôi có: lỗi

<uses-permission android:name="android.permission.CAMERA"/> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
<uses-feature android:name="android.hardware.camera"/>

NullPointerException tại dòng 73 của MainActivity.java. Đó là dòng nào? – Piovezan

Trả lời

vẫn gặp không may mắn, tôi đã thay đổi mã ý định của máy ảnh thành:

@Override 
     public void onClick(View v) { 


      String _path = Environment.getExternalStorageDirectory().getAbsolutePath() + "sunpic.jpg"; 
      File file = new File(_path); 
      //Uri fileUri = Uri.fromFile(file); 
      Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
      intent.putExtra(MediaStore.EXTRA_OUTPUT, file);    
      //File file = new File(Environment.getExternalStorageDirectory().getPath()); 
      intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); 
      startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); 


      } 

    }); 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    //super.onActivityResult(requestCode, resultCode, data); 
     if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK) { 

        //Uri file = data.getData(); 
        FileInputStream is; 
        try { 
         is = new FileInputStream("mnt/sdcard/sunpic.jpg"); 


        Bitmap bmp = BitmapFactory.decodeStream(is); 
        //Bitmap bmp = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), file); 
        //Bitmap bmp = (Bitmap) data.getExtras().get("data"); 
        bmp.getPixels(pixels, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight());

Phần còn lại của điều này giống với nội dung trong bài đăng gốc của tôi.

Trình ghi nhật ký trống và ngay khi tôi chụp ảnh trên máy ảnh, nó bị treo.

gì tôi đã cố gắng trước đó không bao gồm

FileInputStream is; 
        try { 
         is = new FileInputStream("mnt/sdcard/sunpic.jpg");

và có dòng tiếp theo như

Bitmap bmp = BitmapFactory.decodeStream("sunpic.jpg");

Nhưng điều đó một cách nhất quán nhổ ra lỗi NullPointer, mà tôi thực sự không hiểu tại sao, mặc dù đọc nhiều chủ đề khác/tài nguyên web khác về nó.

Không có hành vi phạm tội nhưng tôi nghĩ bạn cần đọc một cuốn sách cơ bản về Java và Android cơ bản trước khi đăng ở đây ... – philask
