迁移到在 AndroidX 设备上运行的 AndroidX(29) 后显示崩溃
ClassNotFoundException: config_inputEventCompatProcessorOverrideClassName
项目编译并运行在andorid10.0启动时崩溃 当单击 editText 时，我收到此错误
NullPointerException: Attempt to invoke virtual method 'java.util.List android.view.InputEventCompatProcessor.processInputEventForCompatibility(android.view.InputEvent)' on a null object reference

最佳答案
我在 Android 10 上遇到了同样的问题。我使用了 Restring通过 attachBaseContext(newBase: Context) 注入(inject)自定义 Resource 实现的库。这里的每个人都提到 Resource 的构造函数被标记为已弃用，但这并不会真正导致问题。
我深入研究了 Android 源代码，发现了引发 NPE 的真正原因。
ViewRootImpl.java 中受影响的行:
String processorOverrideName = context.getResources().getString(
R.string.config_inputEventCompatProcessorOverrideClassName);
if (processorOverrideName.isEmpty()) {
// No compatibility processor override, using default.
mInputCompatProcessor = new InputEventCompatProcessor(context);
} else {
InputEventCompatProcessor compatProcessor = null;
try {
final Class<? extends InputEventCompatProcessor> klass =
(Class<? extends InputEventCompatProcessor>) Class.forName(
processorOverrideName);
compatProcessor = klass.getConstructor(Context.class).newInstance(context);
} catch (Exception e) {
Log.e(TAG, "Unable to create the InputEventCompatProcessor. ", e);
} finally {
mInputCompatProcessor = compatProcessor;
}
}
就我而言，使用 Restring 库，我定义了一种解析字符串键并返回文本的新方法。如果该 key 在我的字符串存储库(简单 HashMap)中不可用或作为字符串资源不可用，则它会返回该 key 本身。因此永远不会为空，但根据代码，它将尝试加载为自定义 InputEventCompatProcessor，但会失败，并且 mInputCompatProcessor 将为 null。
确保自定义Resource中的所有版本的getText()都遵循原始行为，并且不会导致NPE崩溃。例如，确保 R.string.config_inputEventCompatProcessorOverrideClassName 资源在不可用时将解析为空字符串。
这将解决真正的问题，您仍然可以使用已弃用的资源构造函数。
