NullPointerException in TextInputLayout on Xiaomi with Android 10

问题

最近我在我的安卓应用中开始使用 TextInputLayout。之后，奇怪的 NullPointerException 错误开始出现。这些错误只在搭载 Android 10 的 小米（Xiaomi） 设备上发生。

  1. 致命异常: java.lang.NullPointerException
  2. 尝试调用空对象引用上的直接方法 'void android.widget.Editor$SelectionModifierCursorController.initDrawables()'
  3. android.widget.Editor$SelectionModifierCursorController.access$300

没有办法重现这个错误（我没有小米设备）。在搜索互联网时，我意识到这个错误发生在尝试在 TextInputLayout 字段中输入电子邮件时。

互联网上有React Native的解决方案：https://github.com/facebook/react-native/issues/27204

不幸的是，我还没有找到Java的解决方案。

来自Crashlytics的截图：

英文:

I recently started using TextInputLayout in my android app. After that, strange NullPointerException errors started to appear. These errors only occur on Xiaomi devices with Androind 10.

  1. Fatal Exception: java.lang.NullPointerException
  2. Attempt to invoke direct method 'void android.widget.Editor$SelectionModifierCursorController.initDrawables()' on a null object reference
  3. android.widget.Editor$SelectionModifierCursorController.access$300

There is no way to reproduce the error (I do not have a Xiaomi device). Searching the Internet realized that this error occurs when trying to enter email in the TextInputLayout field.

There is a solution for React Native on the internet: https://github.com/facebook/react-native/issues/27204

Unfortunately, I have not been able to find a solution for Java.

得分: 1

以下是我为了解决崩溃问题所做的操作。它将在编辑电子邮件地址时禁用光标，但不会导致崩溃。

  1. if (android.os.Build.MANUFACTURER.equals("Xiaomi", ignoreCase = true) &&
  2.     android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.Q) {
  3.     editText.isCursorVisible = false;
  4. }
英文:

This is what I did to fix the crash. It will disable the cursor when editing an email address, but it will not crash.

  1. if (android.os.Build.MANUFACTURER.equals("Xiaomi", ignoreCase = true) &&
  2.     android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.Q) {
  3.     editText.isCursorVisible = false
  4. }
