Android jigsaw puzzle game development full record 5

Today, we can finally end this project. We have prepared for it a few days ago. I believe that the last day is easy. International Practice:

The last thing we need to accomplish is our main function-the jigsaw puzzle interface.

The layout is relatively simple and has been completed a few days ago. Now we have to do the following:

1. Timing steps: this is a basic function of the game. In fact, it is relatively simple. Just record the number of successfully moved steps and display a timer.

2. Adjust the image size to a proper proportion: This method has been implemented a few days ago.

3. Click the GridView icon and move the image. The method for moving the image has been implemented a few days ago.

4. Determine whether the puzzle is completed: Alas, it has already been implemented.

5. Click "show source image". Only one ImageView is displayed.

6. Click "reset" to reprocess the uploaded image.

After writing the basic idea, it seems very complicated. It is very easy to sort it out. A lot of preparation work is done, which will make our thinking clearer.

I think the annotation and code style are good. I hope you will like it.

PS: If you need the source code, please leave a message. In fact, you can implement it by yourself based on this idea, which greatly improves yourself. If you can optimize my code, it will be better, you can learn and communicate with each other.
