要在Android中从imageView保存图像

v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());

Matrix matrix = new Matrix();
matrix.postScale(scaledWidth, scaledHeight);

Bitmap resizedBitmap = Bitmap.createBitmap(originalBitmap, 0, 0,
    originalBitmap.width(), originalBitmap.height(), matrix, true); 

OutputStream fOut = null;
File file = new File(strDirectoy,imgname);
fOut = new FileOutputStream(file);

resizedBitmap.compress(Bitmap.CompressFormat.PNG, 0, fOut);
fOut.flush();
fOut.close();
