今天来编写保存图片函数

   //图片储存
    public static String saveBitmap(String name, Bitmap bm, Context mContext) {
        String TargetPath = mContext.getFilesDir() + "/images/";
        Log.d("Save Bitmap", "Save Path="+TargetPath+name);
        if (!fileIsExist(TargetPath)) {
            Log.d("Save Bitmap", "TargetPath isn't exist");
        } else {
            //如果指定文件夹创建成功,那么我们则需要进行图片存储操作
            File saveFile = new File(TargetPath, name);

            try {
                FileOutputStream saveImgOut = new FileOutputStream(saveFile);
                // compress - 压缩的意思
                bm.compress(Bitmap.CompressFormat.JPEG, 80, saveImgOut);
                //存储完成后需要清除相关的进程
                saveImgOut.flush();
                saveImgOut.close();
                Log.d("Save Bitmap", "The picture is save to your phone!");
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
        return TargetPath+name;
    }

这个函数可以保存相应的图像到指定目录以便预测及访问历史
