Question

我更改了我的应用，因此用户可以为整个应用设置2种不同的样式。我已经更新了我创建的自定义选项卡，因此它们链接到一个样式，该样式依次转换（取决于所选样式）链接到drawable中的Selector xml（即为选定或未选择显示的内容）。

运行此操作会给我以下错误

Custombackground的代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabsLayout" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    style="?custom_tab_background_selector">

    <TextView 
        android:id="@+id/customTabsText" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        style="?custom_tab_text_selector">
    </TextView>

</LinearLayout>

调用此

的方法

private static View createTabView(Context pContext, String pTabTitleText) {

        View view = LayoutInflater.from(pContext).inflate(R.layout.custom_tabs_background, null);

        TextView tv = (TextView) view.findViewById(R.id.customTabsText);

        tv.setText(pTabTitleText);

        return view;

    }

其余的只是一个xml主题，它指向一个Selector XML，它反过来指向一些drawble xml文件。这是Selector XML

<?xml version="1.0" encoding="utf-8"?>
<selector 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <!--  Active tab -->
    <item 
        android:state_selected="true" 
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/custom_tab_background_selected_black" />
    <!--  Inactive tab -->
    <item 
        android:state_selected="false" 
        android:state_focused="false"
        android:state_pressed="false" 
        android:drawable="@drawable/custom_tab_background_unselected_black" />
    <!--  Pressed tab -->
    <item 
        android:state_pressed="true" 
        android:drawable="@android:color/transparent" />
    <!--  Selected tab (using d-pad) -->
    <item 
        android:state_focused="true" 
        android:state_selected="true"
        android:state_pressed="false" 
        android:drawable="@android:color/transparent" />
</selector>

关于我为什么会收到此错误的任何想法都会很棒。谢谢你的时间

Answer 1

看来我跟踪了它。

选项卡的背景我使用的是android：background = ....但也使用相同的文本颜色，它应该是android：textColour = ....

现在一切正常。对不起困惑

将样式添加到自定义选项卡
