Building a timeline using a custom view

I am creating an Android application with synchronized events, and I'm not sure which layout I should use to build the timeline.

Events can have different heights and can increase when you click on them, but they have the same width;

              .
              .
              .
------------- |
| Event 4   > | --------------
------------- | < Event 7    |
              | |            |
              | --------------
              .
              .
              .

I have two types of views:

  • EventView witch holds event information and throws his plan
  • TimeBarView witch is a strip in the middle (has some property and extends over a very long period of time

How can I place my items so that he respects the time on my timeline (for example, 1 week can be 10px)

Any help is appreciated. Thank!

        View child = getChildAt(i);
        if (child.getVisibility() != GONE) {
            // do the layout for each child here, with child.layout
