java - getColor 方法上的资源未找到异常

Question

我正在使用第三方库来使用“幻灯片”( fragment )创建介绍。但是，我收到了 ResourcesNotFoundException，您可以在下面看到。

我不知道异常中提到的这个getColor方法在哪里。它可以从每张幻灯片的 backgroundColor() 属性中抛出吗？

这是我的代码:

public class Tutorial extends MaterialIntroActivity {

private Integer[] tutorialImages = {
        R.mipmap.image_main,
        R.mipmap.image_long_tap,
        R.mipmap.image_menu_slide,
        R.mipmap.image_auto_save,
        R.mipmap.image_data_security,
        R.mipmap.image_donation,
        R.mipmap.image_tutorial
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    addSlide(new SlideFragmentBuilder()
            .title("Main Screen")
            .description("Search through the entire Dokkan Cards database and find any card you like.")
            .image(tutorialImages[0].intValue())
            .backgroundColor(R.color.mainScreen)
            .build());


    addSlide(new SlideFragmentBuilder()
            .title("Tap & Long-Press Actions")
            .description("Tap on any card icon to view it's details or Long-press on it to add it to either one of your boxes")
            .image(tutorialImages[1].intValue())
            .backgroundColor(R.color.long_tap)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Side Menu")
            .description("Swipe from left to right to access a handful of menu options")
            .image(tutorialImages[2].intValue())
            .backgroundColor(R.color.side_menu)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Auto-Save")
            .description("This app saves your box data automatically when you close the app so that you don't have to worry about saving manually")
            .image(tutorialImages[3].intValue())
            .backgroundColor(R.color.auto_save)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Data Security")
            .description("Your data is 100% safe since it cannot be accessed by anyone else.All data are stored locally on your device and not on a server or cloud")
            .image(tutorialImages[4].intValue())
            .backgroundColor(R.color.data_security)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Donations")
            .description("Although donations are not mandatory, they help a lot in the app's development process. You can submit your donation via the website tab in the app's side menu.")
            .image(tutorialImages[5].intValue())
            .backgroundColor(R.color.donations)
            .build());

    addSlide(new TutorialDisclaimerSlide());

    addSlide(new SlideFragmentBuilder()
            .title("That's it")
            .description("That's the end of this tutorial.You can access it at any time from the top right corner of the app")
            .image(tutorialImages[6].intValue())
            .backgroundColor(R.color.tutorial_end)
            .build());
}
}

这是颜色.xml 文件:

</resources>

这是我得到的异常:

知道我做错了什么和/或如何跟踪抛出异常的 getColor() 方法吗？

Answer 1

看起来是 known issue与图书馆。

它说:

you need to necessarily override and specify your own values while creating a custom fragment.

 @Override public int buttonsColor() { 
    return R.color.custom_slide_buttons; 
 }

就我个人而言，我会扩展MaterialIntroActivity，然后做这样的事情:

@Override
private int color(@ColorRes int color) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        return getResources().getColor(color, getTheme()));
    } else {
        return getResources().getColor(color));
    }
}
