Simple way to get images from the Internet in Android programming

This article demonstrates a simple method for Android programming to obtain images from the internet. Shared for everyone's reference, as follows:

To get images from the internet, you first need network access permissions, which will not be written here, as it has been written in previous articles. Also, the layout method will not be written, as it would also be a simple layout without much significance, so let's go directly to the core code:

This is a simple class I use to get images from the internet.

public static Bitmap getImage(String Url) throws Exception {
  try {
    URL url = new URL(Url);
    String responseCode = url.openConnection().getHeaderField(0);
    if (responseCode.indexOf("200") < 0)
      throw new Exception("The image file does not exist or the path is incorrect, error code: "); + responseCode);
    return BitmapFactory.decodeStream(url.openStream());
  } catch (IOException e) {
    // TODO Auto-generated catch block
    throw new Exception(e.getMessage());
  }
}

This class returns a Bitmap object,

Below is a simple call to the class:

Here is the core code directly:

Bitmap mBitmap;
// Directly obtain the image:
private void RefreshDB() {
  try {
    sendMSG(Declare.START, "正在加载图片......");
    mBitmap = DownFile.getImage(图片地址);
    sendMSG(Declare.STOP, "");
  } catch (Exception e) {
    // TODO Auto-generated catch block
    sendMSG(Declare.ERROR, e.getMessage());
  }
}

Here is a simple scrollbar indicating that the current program is running. It is implemented by sending messages, and the specific implementation of that message is not written, that message has no head this core code implementation.

Execute after loading is complete:

mImageView1.setImageBitmap(mBitmap);
