当纺纱listrow内填充的Android onListItemClick不工作(android o

2019-07-29 11:49发布

我想填充列表视图中的行包含一个复选框,四个textviews,和两个微调。 在各行上微调的值需要是不同的,因为它们直接关系到该行实际的项目。 只是为了让纺织家更是有点复杂,他们旁边的两个文本字段是不可见的(setVisibility(View.GONE)),除非该复选框被选中。 我只是想列表项的点击能(不是复选框),以及纺纱必须点击能够一旦被显示。

我所有的代码,除了当纺纱被填充,然后我失去点击该行的列表项的能力是否正常工作。 我仍然可以从该行的微调选择值,但触及其他地方该行确实什么都没有。 有没有数据返回到纺纱一些行和他们继续,所以我认为这是值得做的与连接到纺纱适配器正常工作。

此外,我知道我将不得不考虑列表视图回收,但我还没有得到那么远呢。

我希望有人能指出什么是错在这里我去完全疯了。

这里是列表视图XML

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

<TextView android:id="@+id/android:empty"
          android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/empty"/>
</LinearLayout>

这里是行XML

预先感谢任何帮助你可以给。

Answer 1:

你可以尝试添加android:descendantFocussability=blocksDescendants到最高的线性布局。 这可能是有益的。
