Load 图形到内存
2. 根据当前屏幕分辨率的大小 , 加载图片
Display currentDisplay = getWindowManager().getDefaultDisplay();
int dw = currentDisplay.getWidth();
int dh = currentDisplay.getHeight();
BitmapFactory.Options bmpFactoryOptions = new
BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeFile(imageFilePath,
bmpFactoryOptions);
int heightRatio =
(int)Math.ceil(bmpFactoryOptions.outHeight/(float)dh);
int widthRatio =
(int)Math.ceil(bmpFactoryOptions.outWidth/(float)dw);
Log.v("HEIGHTRATIO",""+heightRatio);
Log.v("WIDTHRATIO",""+widthRatio);
