Android - drag and drop - list rearrange

开发者 https://www.devze.com 2022-12-14 17:43 出处:网络
How can I create a list where I can rearrange list items with dragging list rows to another row and so on (to change to order)?

How can I create a list where I can rearrange list items with dragging list rows to another row and so on (to change to order)?

Just like on the HTC Hero in the clocks app where you can rearrang开发者_C百科e the order of clocks?


Even though this question is already answered. I struggled using the music app as an example, so I created a simple Drag and Drop List project to help others that can be found here


Pay special attention to this one

com.android.music.TouchInterceptor


You can also try my recent implementation here:

  • https://github.com/bauerca/drag-sort-listview

It gives smooth scrolling while dragging and supports list items with arbitrary heights. Lots of jumpy behavior has also been removed as compared to the TouchInterceptor.


It's in platform/packages/apps/Music/src/com/android/music/TouchInterceptor.java. Here's a direct link:
https://android.googlesource.com/platform/packages/apps/Music/+/master/src/com/android/music/TouchInterceptor.java


Hint: download the android sources and have a look how the Music app (packages\apps\Music) implements this functionality.
