Android programming to read the local SD card picture method _android

This article describes the Android programming method for reading local SD card images. Share to everyone for your reference, specific as follows:

Private Bitmap Getdiskbitmap (String pathstring)
{
  Bitmap Bitmap = null;
  Try
  {
    File File = new file (pathstring);
    if (file.exists ())
    {
      bitmap = Bitmapfactory.decodefile (pathstring);
    }
  catch (Exception e)
  {
    //Todo:handle exception
  }
  return bitmap;
}

This method realizes to read a picture from the local path, can be JPG, BMP, PNG and so on many kinds of formats.

PathString is a local picture path such as: "Mnt/sdcard/1.jpg"

File File = new file (pathstring);
if (file.exists ())
{bitmap = Bitmapfactory.decodefile (pathstring);}

After reading to the local file, determine if the file exists.

Copy Code code as follows:

Bitmapfactory.decodefile (pathstring);

Decodes a local file, which can be a variety of picture formats. Returns the Bitmap object
