不断变化的抽屉式导航栏选择项目颜色从默认的蓝色 [英] Changing Navigation Drawer Selected Item Color from default blue

问题描述

您好，感谢阅读。

我有我的Andr​​oid应用导航抽屉一个问题，我无法从蓝色改变颜色 - 我已经去了来自因此，所有的其他问题，提到了Android的文件，并尝试了一切至今...但仍没有运气。我真的希望有人能够帮助。

I have a problem with my android apps navigation drawer where I cannot change the color from blue - I have went over all the other questions from SO, referred to the android documentation, and have tried everything so far... but still no luck. I really hope someone can help.

在code到目前为止：

The code so far:

my_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Blue still showing up! -->
    <item android:state_activated="true" android:drawable="@color/lightPink" />
    <item android:state_selected="true" android:drawable="@color/lightPink" />
    <item android:state_pressed="true" android:drawable="@color/lightPink" />
    <item android:state_focused="true" android:drawable="@color/lightPink" />
    <item android:drawable="@color/lightPink" />

</selector>

styles.xml

<item name="android:activatedBackgroundIndicator">@drawable/my_background</item>

fragment_navigation_drawer.xml

fragment_navigation_drawer.xml

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:listSelector="@drawable/my_background"
    tools:context="com.randompractice.app.NavigationDrawerFragment"

/>

我一直停留在这24小时，现在，它是推动我疯了。对于这样一个愚蠢的变化不大，我的好奇心，告诉我实现，已经变成了一个研究项目。任何人都可以看到我在做什么错了？

I have been stuck on this for 24 hours now and it is driving me crazy. For such a silly little change that my curiosity told me to implement, has turned into a research project. Can anybody see what I am doing wrong?

推荐答案

首先，我会尝试删除了android：listSelector属性，因为我不认为有必要

First, I would try removing the android:listSelector attribute, as I don't believe it is necessary.

接下来，我会仔细检查你有所有这些步骤：

Next, I would double check you have all these steps:

• 在您的应用程序的主题，尝试添加

的themes.xml

<style name="Theme.mytheme" parent="android:Theme.Holo">
    <item name="android:activatedBackgroundIndicator">@drawable/activated_background</item>
</style>

• 的绘制应该是指含有像选择一个文件（就像你有）

activated_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/my_color" android:state_activated="true" />
    <item android:drawable="@android:color/transparent" />
</selector>

colors.xml

<resources>
    <item name="my_color" type="color">#ff0000</item>
</resources>

• 最后，请确保您使用的应用的主题在你的清单中的应用程序标记

AndroidManifest.xml中

android:theme="@style/Theme.mytheme"
