Question

我在listview中带有片段的复选框有问题。

为什么当我点击复选框时这是黄色的？我看不到支票符号;在活动中它是好的....我给你看截图。

我希望你能帮助我！

适配器代码：

您可以设置这样的复选框布局，希望这对您有帮助。

<CheckBox 
        android:id="@+id/chk_box"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:checked="false"
        android:button="@drawable/custom_checkbox"
        android:layout_alignParentLeft="true" />

并且您的自定义复选框xml文件是

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
        android:drawable="@drawable/checked" />
    <item android:state_pressed="true"
        android:drawable="@drawable/upchecked" />
    <item android:drawable="@drawable/upchecked" />
</selector>

并选中或取消选中您想要设置的图像。您访问此http://androidexample.com/Custom_Checkbox_With_The_Use_Of_Selectors_And_Shapes/index.php?view=article_discription&aid=80
