Android N在TextAppearanceSpan中崩溃 [英] Android N crashes in TextAppearanceSpan

问题描述

自从将Nexus 5X升级到Android N后，使用EditText时发生以下崩溃:

Since upgrading my Nexus 5X to Android N, I have the following crash when using EditText:

   java.lang.UnsupportedOperationException: Failed to resolve attribute at index 6: TypedValue{t=0x2/d=0x101009b a=1}
       at android.content.res.TypedArray.getColorStateList(TypedArray.java:528)

       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:755)

当单击已经有一些文本的EditText时，会发生这种情况.我假设它是自动更正弹出窗口或类似的东西.

It happens when clicking on an EditText that has some text already. I am assuming it is the auto-correct popup or something similar.

我的应用使用了支持库24.2.0和Theme.AppCompat.Light.NoActionBar

My app uses support libs 24.2.0 and Theme.AppCompat.Light.NoActionBar

如果我除了在主题中添加colorAccent之外，还添加android:colorAccent，效果很好:

It works fine if I add android:colorAccent in addition to just colorAccent in my theme:

<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/mainBrandColor</item>
    <item name="colorPrimaryDark">@color/mainBrandDarkerColor</item>
    <item name="colorAccent">@color/mainBrandColor</item>
    <item name="android:colorAccent">@color/mainBrandColor</item>
</style>

但这不是必需的，因为我继承自Theme.AppCompat.

But this shouldn't be needed as I inherit from Theme.AppCompat.

我制作了一个展示问题的小应用程序:

I made a small app that showcases the problem:

推荐答案

在堆栈跟踪中，有对RecommendationionsPopupWindow的引用，这使我想到了禁用针对EditText的建议.

In the stack trace there was a reference to SuggestionsPopupWindow that made me think of disabling suggestions for EditText.

我使用以下代码作为变通方法:

I used the following code as a workaround:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        if ((editText.getInputType() & InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS) != InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS) {
            editText.setInputType(editText.getInputType() | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
        }
    }

我们也可以用XML设置inputType，但是上面的代码允许我们将TYPE_TEXT_FLAG_NO_SUGGESTIONS添加到现有的输入类型.

We can also set inputType in XML, but the above code allows us to add TYPE_TEXT_FLAG_NO_SUGGESTIONS to existent input type.
