使用chrisjenx CalligraphyLayoutInflater时出现InflateException，android.view.InflateException [英] InflateException when using chrisjenx CalligraphyLayoutInflater , android.view.InflateException

问题描述

所以在我们的项目中，我们使用书法库，它没有任何问题，但是现在在我添加的一项活动中，它随着以下堆栈跟踪而不断崩溃:

Hi So in our project we are using calligraphy library , it works with no issues but now in one of the activity i added it keeps crashing with the following stacktrace:

我检查了一些答案，但看不到有人遇到textview问题.

I checked a few answers but cant see anyone facing issue with textview.

我在活动中对书法的重视程度如下

I am attaching to calligraphy as follows in my activity

@Override
protected void attachBaseContext(Context newBase) {
  super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}

活动主题如下

    <style name="AppTheme.Compat.ActionBar.Dark.NoBackground" parent="AppTheme.Compat.ActionBar.Dark">
        <item name="android:windowBackground">@null</item>
        <item name="android:textColor">@color/alert_title</item>
        <item name="android:textColorPrimary">@color/gray400</item>
        <item name="android:colorAccent">@color/alert_button</item>
    </style>

我注意到studio对android:colorAccent发出警告，并替换为"colorAccent"，删除了警告，但崩溃仍然存在.任何线索我在这里做错了什么??

I noticed studio giving warning for android:colorAccent and replace with "colorAccent" that removed the warning but the crash remained . Any clues what am I doing wrong here ??

推荐答案

最后确定了问题，因为根据崩溃日志，问题是在Textview中发生的

Finally figured out the problem , Since the issue was happening in Textview as per the crash logs

原因:android.view.InflateException:二进制XML文件第13行:膨胀类TextView时出错

Caused by: android.view.InflateException: Binary XML file line #13: Error inflating class TextView

TLDR:不要将setbackground用于容易发生bug的TextView(三星)，尤其是其Vector可绘制的情况下.

我通过删除textview验证了崩溃停止发生的问题.问题是我曾经为我的textview设置背景图像，这是一个SVG图像，并且我已经使用了appCompact库(v23).仅通过"app:srcCompat"或"setImageResource()"支持设置矢量可绘制，这是使用矢量可绘制的万无一失的方法.

I verified by removing the textview the crash stopped happening.The issue was i used to set background image for my textview and it was a SVG image and i have been appCompact library(v23). Setting vector drawable is only supported via "app:srcCompat" or "setImageResource()" as the foolproof way to use vector drawable.

我阅读了此博客文章，以查看 https ://android-developers.googleblog.com/2016/02/android-support-library-232.html 我看到以前支持的Textview已被删除，这意味着它不稳定且容易出错.

I read the this blog post to see https://android-developers.googleblog.com/2016/02/android-support-library-232.html I see previous supported Textview has now been striked out , which means its not stable and bug prone.

我从textview中移除了Vector可绘制对象，并在紧靠textview下方的位置添加了另一个Imageview，并使用"src:compact"绘制了矢量可绘制对象，因此在视觉上它们看起来仍然相同，即具有背景的Text视图.

I removed the Vector drawable from textview and added a another Imageview just below textview with the vector drawable using "src:compact", so that visually they still look same i.e a Text view with background.

如果应用大小不成问题，您还可以使用png/jpg资源，并避免在布局中创建额外的imageview.

If app size isnt a issue you can also use a png /jpg resource and avoid the creation of extra imageview in your layout.
