Question

我有一个非常莫名其妙的时间试图解决这个主题问题。我有两个独立的应用程序，它们都具有相同的样式xml，夜间颜色，而不是夜间颜色文件。他们都有着色的矢量绘图作为drawable。事情就是一个人崩溃，一个人没有。还应该注意的是，该应用程序仅在Android 5.0上崩溃。以上任何工作和kitkat似乎都有效。

以下是崩溃报告：

这是导致崩溃的夜间颜色xml - 有趣的是，当设置为＃212121时导航抽屉颜色导致崩溃，但是当它设置为@android时：颜色/黑色它工作正常：

<resources>>

    <color name="color_primary_dark">#212121</color>
    <color name="accent_primary">@color/accent_material_dark</color>
    <color name="back_primary">#FF303030</color>
    <color name="list_selected_primary">@color/accent_material_dark_selected</color>
    <color name="text_third">@android:color/tertiary_text_dark</color>
    <color name="text_second">@android:color/secondary_text_dark</color>
    <color name="text_main">@android:color/primary_text_dark</color>
    <color name="drawable_tint">@null</color>
    <color name="dialog_back">#424242</color>
    <color name="action_primary">#212121</color>
    <color name="inverse_text_third">@android:color/tertiary_text_light</color>
    <color name="inverse_text_second">@android:color/secondary_text_light</color>
    <color name="inverse_text_main">@android:color/primary_text_light</color>
    <bool name="dark_status">false</bool>
    <color name="navigation_primary">#212121</color>

</resources>

我看了一下AOSP的5.0代码（http://androidxref.com/5.0.0_r2/xref/frameworks/base/core/java/android/app/Activity.java）

这是被调用的方法：

@Override
protected void onApplyThemeResource(Resources.Theme theme, int resid,
        boolean first) {
    if (mParent == null) {
        super.onApplyThemeResource(theme, resid, first);
    } else {
        try {
            theme.setTo(mParent.getTheme());
        } catch (Exception e) {
            // Empty
        }
        theme.applyStyle(resid, false);
    }

    // Get the primary color and update the TaskDescription for this activity
    if (theme != null) {
        TypedArray a = theme.obtainStyledAttributes(com.android.internal.R.styleable.Theme);
        int colorPrimary = a.getColor(com.android.internal.R.styleable.Theme_colorPrimary, 0);
        a.recycle();
        if (colorPrimary != 0) {
            ActivityManager.TaskDescription v = new ActivityManager.TaskDescription(null, null,
                    colorPrimary);
            setTaskDescription(v);
        }
    }
}

崩溃的行是getColor。您为特定主题指定的颜色似乎无法解析为颜色。检查您的资源，并通过API (TypedArray).getColor()确认可以将其解析为一种颜色：

注意它对错误的说法：

UnsupportedOperationException如果属性已定义但未定义 整数颜色或颜色状态列表。

DayNightTheme适用于一个应用程序而不是另一个应用程序？
