Question

在我的xml中有两个列表视图（Area1和Area2），在Area2中有动态元素，当我点击任何项目时，它应该填充在Area1（另一个listview，其大小始终为1）。我的问题是itemClickListener无法正常工作。

XML是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/light_grey" 
>

<RelativeLayout
    android:id="@+id/top1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <RelativeLayout
        android:id="@+id/top"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"

 android:background="@drawable/listrow_layerlist_background_dark_purple"
        android:padding="10dp" >

        <LinearLayout

            android:orientation="vertical" >

            <TextView

Answer 1

如果您想更改ListView中显示的数据，则需要拨打填充notifyDataSetChanged()的适配器上的ListView。

因此，单击该按钮时，请更改适配器中的数据并调用notifyDataSetChanged()

Answer 2

尝试设置

android:descendantFocusability="blocksDescendants">

到父布局并设置

android:clickable="false"
    android:focusable="false">

对所有观看，这将使itemClickListener运作良好。

listView.setOnItemClickListener（）在Android中不起作用
