覆盖引用的样式属性 [英] Overriding referenced style attributes

问题描述

到<一看完后href="http://developer.android.com/guide/topics/resources/accessing-resources.html#ReferencesToThemeAttributes">References为主题属性我想引用我已经设置了我的自定义主题的属性值。

After reading through References To Theme Attributes I am trying to reference the value of an attribute in the my custom theme that I have set.

我申请一个用户定义的样式为 CheckedTextView

I am applying a user-defined style to a CheckedTextView

<CheckedTextView
    android:id="@+id/contactInfo"
    style="@style/ListViewCheckedTextViewRowStyle" >
</CheckedTextView>

用户定义风格定义为：

The user-defined style is defined as :

<style name="ListViewCheckedTextViewRowStyle" parent="@style/ListViewRowStyle">
    <item name="android:checkMark">?android:listChoiceIndicatorMultiple</item>
</style>

我的主题我创建的定义是：

My theme I created is defined as :

<style name="Theme.Yellowgreen" parent="android:Theme.Holo.Light.DarkActionBar">
    <item name="android:listChoiceIndicatorMultiple">@drawable/btn_check_holo_light</item>
</style>

但是，被显示的对号造型是设备的默认主题的绘制，而不是我的用户定义的绘制。

However, the checkMark styling that gets displayed is the device's default theme's drawable and not my user defined drawable.

我可以有我的显示绘制的唯一方法是：

The only way I can have my drawable displayed is with :

<style name="ListViewCheckedTextViewRowStyle" parent="@style/ListViewRowStyle">
    <item name="android:checkMark">@drawable/btn_check_holo_light</item>
</style>

但是，这违背了重写此属性，尤其是因为我想重写这个属性在多个主题的整个目的。

But that defeats the whole purpose of overriding this attribute, especially since I would like to override this attribute in multiple themes.

我设置的主题在我的活动的的onCreate（）方法是这样的：

I am setting the theme in the onCreate() method of my Activity like this:

public void onCreate(Bundle savedInstanceState) {
    this.setTheme(R.style.Theme_Yellowgreen);
    super.onCreate(savedInstanceState);
    // ...
}

我也试过来设置主题，在AndroidManifest.xml文件，如：

I also tried to set the theme in the AndroidManifest.xml file like :

<application android:theme="@style/Theme.Yellowgreen" >

但没有奏效。可能是什么问题呢？

But that didn't work. What could be going wrong?

我刚刚创建了一个小样本项目，它看起来像codeI上面张贴的工作。所以，我必须有一个要重写这个属性的一些其他风格或许它与我的布局的XML文件。

I just created a small sample project and it looks like the code i posted above is working. So i must have some other styles which are overriding this property or perhaps it has to do with my layout xml files.

在我大的项目，我有两个片段的活动中的。无论片段的列表视图背靠适配器。在片段A 的适配器 getView（）方法如下：

In my large project, I have two Fragments within an Activity. Both Fragments have Listviews backed by Adapters. In Fragment A the getView() method of the Adapter is as follows:

public View getView(final int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.contact_entry, null);
    }

    //...

    return convertView;
}

在片段B 的适配器 getView（）方法如下：

In Fragment B the getView() method of the Adapter is as follows:

public View getView(final int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.list_item, parent, false);
    }

    //...

    return convertView;
}

的布局定义如下：

The layouts are defined as follows:

list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/list_item"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <include layout="@layout/list_item_header" />

    <include layout="@layout/contact_entry" />

    <View android:id="@+id/list_divider"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@android:drawable/divider_horizontal_dark" />

</LinearLayout>

list_item_header.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/header_text"
    android:layout_width="match_parent"
    android:layout_height="25dip"
    android:background="@color/dark_blue"
    android:gravity="center_vertical"
    android:paddingLeft="6dip"
    android:textColor="@color/white"
    android:textSize="14sp"
    android:textStyle="bold" />

contact_entry.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/contactEntry"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:orientation="horizontal" >

    <QuickContactBadge
        android:id="@+id/contactPic"
        style="@style/ContactPicStyle" />

    <CheckedTextView
        android:id="@+id/contactInfo"
        style="@style/ListViewCheckedTextViewRowStyle" >
    </CheckedTextView>

</LinearLayout>

由于某些原因，在片段B 的主题复选标记属性不正确地呈现，而在片段A 中，勾选使用当前黄绿主题和正确的风格。为什么会这样发生？

For some reason, in Fragment B the themed checkMark attribute is not rendering correctly whereas in Fragment A, the checkMark uses the current YellowGreen Theme and is styled correctly. Why would this be happening?

推荐答案

我认为你需要这条线在你的主题

I think you need that line in your theme

<item name="android:checkedTextViewStyle">@style/ListViewCheckedTextViewRowStyle</item>

所以它是这样的：

so it would look like this:

<style name="Theme.Yellowgreen" parent="android:Theme.Holo.Light.DarkActionBar">
    <item name="android:listChoiceIndicatorMultiple">@drawable/btn_check_holo_light</item>
    <item name="android:checkedTextViewStyle">@style/ListViewCheckedTextViewRowStyle</item>
</style>

更新

问题的更新和一些额外的信息形式的意见后，我们发现这个问题是在上下文。这是同样的错误，我做了我的问题：<一href="http://stackoverflow.com/questions/9005015/android-color-selector-doesnt-work-with-custom-attributes">Android颜色选择不与自定义的工作属性

After question update and some additional information form comments we found that the problem was in Context. It's the same mistake I did in that my question: Android color selector doesn't work with custom attributes

要一个片段通过了活动和其他应用程序。我不是专家，但即使是这两个类都扩展上下文仅活动扩展 ContextThemeWrapper ，里面有关于样式的信息。它可能是有益的阅读文章对未来的理解上下文：<一href="http://www.doubleencore.com/2013/06/context/">http://www.doubleencore.com/2013/06/context/

To one fragment was passed Activity and to the other Application. I'm not an expert but even both of those classes are extending Context only the Activity extends ContextThemeWrapper, which has information about styles. It might be helpful to read that article for future understanding Context: http://www.doubleencore.com/2013/06/context/
