Question

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，我需要在复选框上完全点击，如果我点击该行的其他部分，则复选框不会被勾选。如何确保用户在整行中点击的位置勾选了复选框。

Answer 1

尝试将此属性添加到ListView

机器人：可点击= “真”

另外，我没有看到你在myListView上设置Touch / Click监听器的位置。

Answer 2

尝试更改复选框布局宽度以填充父级，如下所示，

 android:layout_width="fill_parent"

猜猜它会对你有用：）

Answer 3

我会在文本字段中添加一个点击监听器，如果点击则将复选框的状态更改为其相反的状态（单击＆lt; - ＆gt; unlicked）

Answer 4

首先，您可以使用CheckedTextView代替CheckBox。也许只有这项工作。

或

尝试设置CheckBox focusable =“false”，如果不起作用，则可以从XML布局的所有View中聚焦。

Answer 5

如果您在列表项上使用button / checkbox / radiobutton，则列表项不可点击
