Question

我想在我的项目中使用viewpageindicator，但导入它时遇到问题。我的XML中有错误。

Missing styles. Is the correct theme chosen for this layout?
Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.

Failed to find style 'vpiCirclePageIndicatorStyle' in current theme

我的XML文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <com.viewpagerindicator.CirclePageIndicator
        android:id="@+id/indicator"
        android:layout_width="248dp"
        android:layout_height="30dp"
        android:layout_alignParentBottom="true"
        android:layout_below="@id/pager"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="30dp"
        android:padding="3dip" />


</RelativeLayout>

我更新了res / values / styles.xml

<?xml version="1.0" encoding="utf-8"?>

它出了什么问题？如果您需要更多文件进行调试，请告诉我。 THX

Answer 1

<强>问题： Problem

<强>解决方案：

在res/layout/values/styles.xml

您可以找到一些示例here。

<style name="StyledIndicators" parent="@android:style/Theme.Light">
    <item name="vpiCirclePageIndicatorStyle">@style/CustomCirclePageIndicator</item>
</style>

<style name="CustomCirclePageIndicator">
    <item name="fillColor">#000000</item>
    <item name="strokeColor">#000000</item>
    <item name="strokeWidth">1dp</item>
    <item name="radius">6dp</item>
    <item name="centered">true</item>
</style>

在您的活动中添加新样式作为主题，＆＃34; StyledIndicators＆＃34;：

<activity
    android:name=".YourActivity"
    android:theme="@style/StyledIndicators" >
</activity>

之后只需要将主题更改为项目附带的主题，选择Manifest Themes - StyledIndicators。

Answer 2

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="android:Theme.Light.NoTitleBar">
    <item name="vpiCirclePageIndicatorStyle">@style/CustomCirclePageIndicator</item>
</style>
<style name="CustomCirclePageIndicator">
    <item name="fillColor">#FF888888</item>
    <item name="strokeColor">#FF000000</item>
    <item name="strokeWidth">2dp</item>
    <item name="radius">10dp</item>
    <item name="centered">true</item>
</style>
</resources>

现在在您的清单文件中。在

下添加主题属性

<application
    android:icon="@drawable/icon"
    android:label="ViewPagerIndicator Sample"
    android:theme="@style/AppTheme" >

别忘了添加

  android:theme="@style/AppTheme"

Answer 3

使用ViewPagerIndicator的活动需要在其主题中具有适当的样式。

在this sample project中，我演示了使用必备vpiTabPageIndicatorStyle设置自定义主题：

<?xml version="1.0" encoding="utf-8"?>
<resources>

        <style name="AppTheme" parent="@style/Theme.Sherlock.Light">
                <item name="vpiTabPageIndicatorStyle">@style/TabStyle</item>
        </style>

        <style name="TabStyle" parent="Widget.TabPageIndicator">
                <item name="android:textColor">#FF33AA33</item>
                <item name="android:textSize">14sp</item>
                <item name="android:textStyle">italic</item>
                <item name="android:paddingLeft">16dp</item>
                <item name="android:paddingRight">16dp</item>
                <item name="android:fadingEdge">horizontal</item>
                <item name="android:fadingEdgeLength">8dp</item>
        </style>

</resources>

同样的基本方法应该适用于vpiCirclePageIndicatorStyle，我认为ViewPagerIndicator附带的示例代码就是一个例子。

Answer 4

要将自定义样式应用于圆形页面指示符，请在xml布局中直接添加样式属性。

double d = 1000000000;
DecimalFormat df = new DecimalFormat("#");
System.out.println(df.format(d));

无法找到样式vpiCirclePageIndicatorStyle
