用于列表视图的Android自定义项适配器

Question

我想在列表视图中显示时创建一个看起来像这样的项目适配器：

我想用来创建它的数据模型如下所示：

TrainingProgram
   - name: String
   - intervals: Array<TrainingInterval>

TrainingInterval
   - intensityType: Enum {WarmUp, Low, Medium, High, CoolDown}
   - durationInSeconds: Int

现在我想到的布局是这样的：

RelativeLayout
   - programTitle: TextView - set to top left
   - totalTime: TextView - set to top right
   - colorMap: ImageView - set to bottom and with fill parent horizontally

当我想要创建该颜色贴图时，我的问题就开始了，颜色的宽度不同，基于TrainingInterval长度，以秒为单位。

如何从上述模型开始创建该颜色贴图？

Answer 1

颜色贴图，你可以使用LinearLayout.Because LinearLayout中的组件有一个属性＆＃34; layout_weight＆＃34;。就像这样：
