Method of setting image as ImageView background when imageloder loads network image in Android Development

This example describes the method of setting the image as the background of ImageView when imageloder loads the network image in Android development. Share with you for your reference, as follows:

Recently, I came into contact with the development of Android. During the development, imageloder is used to load network pictures, but the pictures loaded by the framework are set by default through the SRC attribute of ImageView, so it does not meet the requirements in some cases. For example, setting SRC can not fill the whole ImageView in some scenarios, but it can be achieved by setting the background, The framework does not provide a way to set the picture as the background. I found some solutions on the Internet for a long time, but it was not what I wanted. So I decided to see how the source code was implemented. Sure enough, I found the "new world" in the source code. I couldn't suppress my inner joy. I quickly wrote a blog to share, and also took notes. I hope it will be helpful to you.

This is the end of the bullshit. We will enter the topic (code above)

The above method is a simple example of using imageloder to load a network picture. If you want to set the picture as the background, the core part is in the class bgimageviewaware. Bgimageviewaware is a custom class, which inherits from the class imageviewaware, When looking at the source code, I found that imageloder sets the loaded pictures to the SRC attribute through the imageviewaware class (interested partners can see the source code themselves, and I won't post the source code), so I just need to rewrite the method of this class to set the pictures to the background

The following is the code of the bgimageviewaware class:

At this step, I have completed the whole function of setting the picture as the background of ImageView (actually very simple ^ ^ ^)
