我正在开发一个带有活动的简单应用程序,我使用碎片.一些屏幕上有一些元素.当我编译并运行应用程序时它工作正常,除了三星Galaxy s3和注释4.我没有从stacktrace得到它有什么不对.

在给我的布局充气时,我得到了这个例外:

E AndroidRuntime: android.view.InflateException: Binary XML file line #11: Binary XML file line #11: Error inflating class <unknown>
E AndroidRuntime:        at android.view.LayoutInflater.inflate(LayoutInflater.java:539)

E AndroidRuntime:        at android.support.v7.widget.LinearLayoutManager$LayoutState.next(LinearLayoutManager.java:1962)

日志中没有"由...引起",但我添加了代码来捕获异常并调用,getCause()直到它返回null,这是事件序列:

android.view.InflateException: Binary XML file line #11: Binary XML file line #11: Error inflating class <unknown>
android.view.InflateException: Binary XML file line #11: Error inflating class <unknown>
Error: Binary XML file line #11: …

带有标签的我的应用有两个主题.在每个主题中,选项卡具有处​​于选定和未选定状态的不同图像.我如何按主题正确引用图像？

例如.我有themes.xml

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

<style name="LightTheme" parent="@android:style/Theme.Light">
    <item name="tabShows">@drawable/ic_tab_shows_unselected_light</item>
    <item name="tabShowsSelected">@drawable/ic_tab_shows_selected_light</item>
    <item name="tabNews">@drawable/ic_tab_news_selected_light</item>
    <item name="tabNewsSelected">@drawable/ic_tab_news_unselected_light</item>
</style>

<style name="DarkTheme" parent="@android:style/Theme.Black">
    <item name="tabShows">@drawable/ic_tab_shows_unselected_dark</item>
    <item name="tabShowsSelected">@drawable/ic_tab_shows_selected_dark</item>
    <item name="tabNews">@drawable/ic_tab_news_selected_dark</item>
    <item name="tabNewsSelected">@drawable/ic_tab_news_unselected_dark</item>
   </style>

我还有一个tab_shows.xml和tab_news.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item  android:state_selected="true" android:drawable="@drawable/ic_tab_shows_selected_light"/>
<item  android:state_selected="false" android:drawable="@drawable/ic_tab_shows_unselected_light" />

如何根据当前主题在选择器中引用所需的图像？这不适合我

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item  android:state_selected="true" android:drawable="?tabShowsSelected"/>
<item  android:state_selected="false" android:drawable="?tabShows" />

在布局文件中这是有效的,我的意思是通过？styleName引用样式

假设我有一个简单的形状drawable绘制环如下:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:dither="true"
    android:innerRadiusRatio="3"
    android:shape="ring"
    android:thicknessRatio="36"
    android:useLevel="false" >

    <gradient
        android:centerColor="@android:color/holo_blue_bright"
        android:centerY="0.001"
        android:endColor="@android:color/holo_blue_dark"
        android:gradientRadius="202.5"
        android:startColor="@android:color/transparent"
        android:type="radial"
        android:useLevel="false" />

</shape>

我将此形状应用为视图背景,如下所示:

<View
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:padding="16dp"
    android:background="@drawable/custom_shape" />

形状的确切细节与这个问题无关 - 只要说我有一个形状就足够了.现在,我不想硬编码形状的各种参数.我们thicknessRatio以此为例.如果我想根据屏幕配置改变厚度比,我当然会使用整数资源,如下所示.我有一个带有以下内容的values.xml:

<item name="thickness_ratio" type="integer" format="integer">56</item>

然后,android:thicknessRatio="@integer/thickness_ratio".

到现在为止还挺好.现在,我也希望我的形状有两种"风格" - 一个"大"和一个"小",我希望查询厚度比不依赖于配置,而是根据应用于视图的样式.这是什么样式和主题.所以,这是我尝试过的:

步骤1:声明厚度比的属性(attrs.xml):

<resources>
        <attr name="thicknessRatio" format="reference" />
</resources>

第2步:使用此属性声明两个样式(styles,xml):

<style name="CustomShapeSmall">
    <item name="thicknessRatio">@integer/thickness_ratio_small</item>
</style>

<style name="CustomShapeLarge">
    <item name="thicknessRatio">@integer/thickness_ratio_large</item>
</style>

第3步:在values.xml中定义两个整数:

<item name="thickness_ratio_small" type="integer" format="integer">32</item>
<item name="thickness_ratio_large" type="integer" format="integer">56</item>

第4步:在Shape Drawable中查询自定义属性:

android:thicknessRatio="?attr/thicknessRatio"

第5步:将所需的样式应用于View:

<View
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:padding="16dp" …

我正在使用attr为我的项目创建一个可绘制的选择器,这样一旦我改变主题颜色,我就不必对可绘制文件进行任何更改.我正在使用以下libs:

compile 'com.android.support:appcompat-v7:+'
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:design:22.2.0'

这是drawable的源代码:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="?attr/colorPrimary" android:state_enabled="true" android:state_window_focused="false"/>
    <item android:drawable="?attr/colorPrimaryDark" android:state_pressed="true"/>
    <item android:drawable="@android:color/darker_gray" android:state_enabled="false"/>
    <item android:drawable="?attr/colorPrimary"/>
</selector>

在这个相同的代码中,如果我用colors.xml文件中定义的颜色替换属性,同样的drawable工作.

样本可绘制颜色:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/color_primary" android:state_enabled="true" android:state_window_focused="false"/>
    <item android:drawable="@color/color_primary_dark" android:state_pressed="true"/>
    <item android:drawable="@android:color/darker_gray" android:state_enabled="false"/>
    <item android:drawable="@color/color_primary"/>
</selector>

提前致谢!

在我的应用程序中,我定义了我在自定义主题中设置的颜色属性:

RES /值/ attrs.xml

<resources>
    <attr name="bbColorPrimary" format="color|reference" />
</resources>

RES /值/ colors.xml

<resources>
    <color name="white">#ffffff</color>
</resources>

RES /值/ style.xml

<style name="MyStyle" parent="@style/Theme.AppCompat.NoActionBar">
    <item name="bbColorPrimary">@color/white</item>
</style>

RES /抽拉/ background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true">
        <shape>
            <solid android:color="?attr/bbColorPrimary" />
        </shape>
    </item>
    <item>
        <shape>
            <solid android:color="@color/transparent" />
        </shape>
    </item>
</selector>

res/drawable/background.xml被设置为某个按钮的背景.应用程序在膨胀res/drawable/background.xml文件时崩溃,但有以下异常:

...
Caused by: java.lang.UnsupportedOperationException: Can't convert to color: type=0x2
            at android.content.res.TypedArray.getColor(TypedArray.java:326)

            at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:172)
....

它适用于高于10的API级别.如果我删除?attr/bbColorPrimary它工作正常,尽管?attr/..在其他资源文件中设置了许多其他调用.我没有使用任何特定于版本的资源文件夹.

我在这做错了什么？

我正在构建我的应用程序,以便它可以受益于多个主题.

我已经到了我想添加自定义项目的阶段,例如

<style name="My.Theme.Default">
...
    <item name="borderColorDialog">@color/red</item>
...
</style>

<style name="My.Theme.Blue">
...
    <item name="borderColorDialog">@color/blue</item>
...
</style>

所以我已经将属性添加borderColorDialog到我的attr文件中,如下所示:

<attr name="borderColorDialog" format="color" />

现在我想测试它.我有一个drawable如下:

<?xml version="1.0" encoding="utf-8"?>
<layer-list 
    xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>

        <shape 
            android:shape="rectangle" >

            <solid 
                android:color="?borderColorDialog" />

        </shape>

    </item> 

    <item
        android:bottom="2dp">

        <shape 
            android:shape="rectangle" >

            <solid 
                android:color="@color/black" />

        </shape>

    </item>
</layer-list>

这对我来说在逻辑上看起来都很合理,但?borderColorDialog引用会使模拟器崩溃:

E/AndroidRuntime(1461): FATAL EXCEPTION: main
E/AndroidRuntime(1461): java.lang.RuntimeException: Unable to start activity ComponentInfo{.MainActivity}: android.view.InflateException: Binary XML file line #26: Error inflating class com.android.internal.widget.ActionBarContainer
E/AndroidRuntime(1461):     at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059)
E/AndroidRuntime(1461):     at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2084) …

我正在开始一个新项目,所以项目或多或少"空".我刚刚添加了MainActivity,带有MainActivtyFragment.我没有向他们添加任何代码.

现在,我编辑styles.xml,看起来像这样:

<resources>
    <!-- Base application theme. -->
    <style name="MyTheme" parent="@android:style/Theme.Material.Light.DarkActionBar">
        <item name="android:windowNoTitle">true</item>
        <!--We will be using the toolbar so no need to show ActionBar-->
        <item name="android:windowActionBar">false</item>
        <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette-->
        <!-- colorPrimary is used for the default action bar background -->
        <item name="android:colorPrimary">#2196F3</item>
        <!-- colorPrimaryDark is used for the status bar -->
        <item name="android:colorPrimaryDark">#1976D2</item>
        <!-- colorAccent is used as the default value for colorControlActivated
             which is used to tint widgets -->
        <item name="android:colorAccent">#FF4081</item>
        <!-- You can also …

我的主题定义为

<style name="AppThemeRed" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimaryRed</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDarkRed</item>
        <item name="colorAccent">@color/colorAccentRed</item>
    </style>

在我的 XML 布局中，我正在做

<android.support.design.widget.AppBarLayout
        android:background="?attr/colorPrimary"
        android:id="@+id/topBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

每当我更改任何主题时，colorPrimary 都会发生变化

但是，如果我在 drawable 中添加了相同的东西，例如

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="?attr/colorPrimary" />
            <corners android:radius="5dp"/>
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle">
            <solid android:color="?attr/colorPrimary" />
            <corners android:radius="5dp"/>
        </shape>
    </item>
</selector>

它因无法膨胀视图而崩溃，该视图的背景设置为 @drawabe/xxxx

如何在我的 XML drawable 中定义主题颜色属性

我在 RecyclerView 中添加了一个 FastScroller 并使用了一个“气泡”-Drawable。

如果我在 API 21 上测试我的应用程序，它可以工作，但如果我在 API 19 上测试它，它会崩溃：
