       Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.frag_tulip_locationmap, container, false); 


      mImaView = (ImageView) rootView.findViewById(R.id.locationmap_tulip); 

      Bitmap bimtBitmap = BitmapFactory.decodeResource(getResources(), 
        R.drawable.tulip_locationmap); 
      mImaView.setImageBitmap(bimtBitmap); 

      /**

      */ 
      usingSimpleImage(mImaView); 
      return rootView; 
     } 

     public void usingSimpleImage(ImageView imageView) { 
      ImageAttacher mAttacher = new ImageAttacher(imageView); 
      ImageAttacher.MAX_ZOOM = 2.0f; // Double the current Size 
      ImageAttacher.MIN_ZOOM = 1.0f; // Half the current Size 
      MatrixChangeListener mMaListener = new MatrixChangeListener(); 
      mAttacher.setOnMatrixChangeListener(mMaListener); 
      PhotoTapListener mPhotoTap = new PhotoTapListener(); 
      mAttacher.setOnPhotoTapListener(mPhotoTap); 
     } 

     private class PhotoTapListener implements OnPhotoTapListener { 

      @Override

Answer 1

它关闭，您所看到的，因为它是银行经营内存不足。如果您控制此图像的分辨率，请勿使其大于现有的最高分辨率手机（2,560 x 1,440）。但要考虑到较低分辨率的设备，绝大多数仍在实施the Android docs for handling large bitmaps中的建议。他们的基本技术是首先检查位图的尺寸，然后根据设备屏幕尺寸进行缩放，以便只有可显示的像素保存在内存中。
