获取Bitmap保存到指定文件夹路径

需要将bitmap保存的时候直接调用，就行了。

public void saveMyBitmap(String bitName, Bitmap mBitmap) throws IOException {    File f = new File(Environment.getExternalStorageDirectory()+ "/Pictures/" + bitName + ".png"); f.createNewFile(); FileOutputStream fOut = null; try { fOut = new FileOutputStream(f); } catch (FileNotFoundException e) { e.printStackTrace(); } mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut); try { fOut.flush(); } catch (IOException e) { e.printStackTrace(); } try { fOut.close(); } catch (IOException e) { e.printStackTrace(); } }
