如何在拖动事件中选择多个复选框

Question

We have multiple checkboxes, as shown below:

We want the user to be able to select first checkbox for A,B,C, by him dragging over the checkboxes. Is this possible in android?

Answer 1

Yes, you could do something like that. You'd have to first start a drag operation and drag a view. If you tried to do it with just your finger, it would be an exercise in gesture detection. But dragging a view would be simple.

Using this tutorial as a guide - http://developer.android.com/guide/topics/ui/drag-drop.html - you should be able to start a drag operation using a click listener on the view you want to drag. Then, as the dragged view enters the bounding boxes (you set up draglisteners on each) of a checkbox, you can set it to checked.
