当listrow中填充了微调器时，android onListItemClick无法正常工作

标签： android spinner

我正在尝试填充列表视图，其中行包含复选框，四个文本视图和两个微调器。每行上的微调器中的值需要不同，因为它们与该行上的实际项直接相关。只是为了使它变得更复杂一点，除非选中复选框，否则微调器和它们旁边的两个文本字段是不可见的（setVisibility（View.GONE））。我只希望列表项可点击（而不是复选框），并且一旦显示，微调器就需要点击。

我的所有代码都正常工作，但是当填充微调器时，我将无法单击该行上的列表项。我仍然可以从该行上的微调器中选择值，但触摸该行上的任何其他位置都没有任何作用。有些行不会将数据返回到微调器，并且它们继续正常运行，因此我认为它与连接到微调器的适配器有关。

此外，我知道我将不得不考虑列表视图回收，但我还没有那么远。

我希望有人能在我疯狂之前指出这里出了什么问题。

这是listview xml          

    <ListView android:id="@+id/android:list"
      android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>

<TextView android:id="@+id/android:empty"

您可以尝试将android:descendantFocussability=blocksDescendants添加到最顶部的线性布局。这可能会有所帮助。
