我正在尝试为我的应用程序制作多个联系人选择器。我正在使用带有复选框的自定义布局来选择多个联系人。我面临的问题是，为了选择任何特定的联系人，我需要准确地单击复选框，如果我单击行的其他部分，复选框不会被勾选。我如何确保用户在整行中单击的任何位置都会选中复选框。

activity_contacts_picker.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Button
    android:id="@+id/btnShow"
    android:layout_
    android:layout_
    android:text="Show Selected" />

<ListView
    android:id="@android:id/list"
    android:layout_
    android:layout_
    android:layout_below="@+id/btnShow" >
</ListView>

</RelativeLayout>

【参考方案1】：

尝试将此属性添加到您的 ListView

android:clickable="true"

另外，我看不到您在哪里为 myListView 设置 Touch/Click 侦听器。

【参考方案2】：

尝试更改复选框布局宽度以填充父项，如下所示，
