Android把Bitmap保存为PNG图像文件的简单代码

public static void saveBitmapAsPng(Bitmap bmp,File f) {     try {       FileOutputStream out = new FileOutputStream(f);       bmp.compress(Bitmap.CompressFormat.PNG, 100, out);       out.flush();       out.close();     } catch (FileNotFoundException e) {       e.printStackTrace();     } catch (IOException e) {       e.printStackTrace();     }  }
