Android：WebView 旋转阻止键盘打开
由于某些特定需求，我在一个活动上有一个 WebView，其旋转由我管理（清单：android:configChanges="keyboardHidden|orientation"）。
出于测试目的，我在其上打开 Google.com。
第一次，Google.com 打开一切都很好。但是，在我旋转设备后，焦点事件似乎停止工作。
当按下 Google.com 的搜索框时，软键盘打不开...甚至 LogCat 上也没有显示任何事件。
在旋转之前，这些是按 google.com 搜索框且键盘打开时出现的日志：
08-19 11:13:19.765: INFO/KeyInputQueue(2497): Input event
08-19 11:13:19.765: DEBUG/KeyInputQueue(2497): screenCaptureKeyFlag setting 0
08-19 11:13:19.769: ERROR/KeyLedTest(2581): KeyLedTest++
08-19 11:13:19.773: ERROR/KeyBoardLed(2497): UpdateState../sys/class/sec/keyboard/keyboard_led state false
08-19 11:13:19.773: ERROR/KeyBoardLed(2497): UpdateState../sys/class/sec/keyboard/keyboard_led state false finished
08-19 11:13:19.773: ERROR/KeyLedTest(2581): service.UpdateState0
旋转后，按时不显示任何日志...
我尝试查看是否调用了 onConfigurationChanged 方法，当按下搜索框时却没有。我还尝试从清单中删除键盘 android:configChanges="orientation" 但没有任何效果。
有人有任何线索吗？
I have a WebView on an activity that the rotation is managed by me (Manifest: android:configChanges="keyboardHidden|orientation") due to some specific needs.
For testing purposes i'm opening Google.com on it.
The first time, that Google.com opens it all works great. But, after I rotate the device, the focus events seem to stop working.
When pressing the search box of Google.com the soft keyboard doesn't open... there are even no events shown on the LogCat.
Before the rotation these are the logs that appear when pressing google.com search box and the keyboard is opening:
08-19 11:13:19.765: INFO/KeyInputQueue(2497): Input event
08-19 11:13:19.765: DEBUG/KeyInputQueue(2497): screenCaptureKeyFlag setting 0
08-19 11:13:19.769: ERROR/KeyLedTest(2581): KeyLedTest++
08-19 11:13:19.773: ERROR/KeyBoardLed(2497): UpdateState../sys/class/sec/keyboard/keyboard_led state false
08-19 11:13:19.773: ERROR/KeyBoardLed(2497): UpdateState../sys/class/sec/keyboard/keyboard_led state false finished
08-19 11:13:19.773: ERROR/KeyLedTest(2581): service.UpdateState0
After rotating none is shown when pressing...
I've tried to see if onConfigurationChanged method is called, when pressing the search box but it is not. I've also tried to remove the keyboard from Manifest being android:configChanges="orientation" but none has taken any effect.
Any clue someone?

也许您的 WebView 没有焦点？
有人提出了类似的问题：为什么 Android WebView 拒绝用户输入？
解决方案是添加以下行：
webView.requestFocus(View.FOCUS_DOWN);Maybe your
WebViewis not having focus?A similar question has been asked: Why is Android WebView refusing user input?
and the solution was to add the following line:
webView.requestFocus(View.FOCUS_DOWN);
