我将手机从 8.0 更新到 8.1，现在当我尝试在我的应用程序（使用 API 级别 25 构建）上点击任何 EditText 或 com.rengwuxian.materialedittext.MaterialEditText 时，我遇到了这个崩溃。

FATAL EXCEPTION: main

布局如下：

 <com.rengwuxian.materialedittext.MaterialEditText
                    android:id="@+id/usernameET"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginBottom="@dimen/padding_xlarge"
                    android:layout_marginTop="@dimen/padding_large"
                    android:enabled="@{!loading}"
                    android:hint="@string/username"
                    android:inputType="text"
                    android:lines="1"
                    android:maxLength="50"
                    android:maxLines="1"
                    android:singleLine="true"
                    android:textSize="@dimen/text_normal"
                    app:met_accentTypeface="fonts/averta_bold.otf"
                    app:met_floatingLabel="highlight"
                    app:met_floatingLabelText="@string/username"
                    app:met_primaryColor="@color/text_dark"
                    app:met_textColor="@color/text_blue"
                    app:met_typeface="fonts/averta_regular.otf" />

您能否告知为什么会发生这种情况以及我该如何解决？

先感谢您！！！

我有类似的问题。在Webview的字段上点击EditText时出现同样的错误。在我的情况下，问题是在attachBaseContext方法中使用了错误的上下文。

旧代码

override fun attachBaseContext(newBase: Context?) {
   super.attachBaseContext(applicationContext.createConfigurationContext(...))
}

固定代码：

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase.createConfigurationContext(...))
}

自动填充框架不再出现错误。我建议您检查一下您是否没有犯过类似的错误，误用了 Context。

对我来说，这似乎是一个直接的回归错误。通过在 Activity.onCreate 中执行此操作，我采取了最务实的方法：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
  getWindow().getDecorView().setImportantForAutofill(
      View.IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS);
}

我花时间在这个错误上：

Fatal Exception: java.lang.NullPointerException: activityToken
       at android.os.Parcel.readException + 2010(Parcel.java:2010)
       at android.os.Parcel.readException + 1950(Parcel.java:1950)
       at android.view.autofill.IAutoFillManager$Stub$Proxy.startSession + 397(IAutoFillManager.java:397)

解决方案：

android:importantForAutofill="no" in XML file in Edit Text.
