Flutter 对虚拟显示器的处理方式 Virtual-Display.md
Flutter 和 Neo 在虚拟显示器的使用其实是不同的，Flutter 借助的是 Presentation 通过 presentation.show() 将 View 显示到虚拟显示器
在这个文档中，Flutter 解释了这个方式实现的一些复杂性，所以目前更多的是使用 Hy
在最新的文档中 https://docs.flutter.dev/platform-integration/android/platform-views , Flutter 已经不把 Virtual Display 当做推荐的使用方式了
Flutter 文档对这两种的性能解释
1 2 3 4 5 6 7 8 9 10 11 12 13 Platform views in Flutter come with performance trade-offs. For example, in a typical Flutter app, the Flutter UI is composed on a dedicated raster thread. This allows Flutter apps to be fast, as the main platform thread is rarely blocked. While a platform view is rendered with hybrid composition, the Flutter UI is composed from the platform thread, which competes with other tasks like handling OS or plugin messages. Prior to Android 10, hybrid composition copied each Flutter frame out of the graphic memory into main memory, and then copied it back to a GPU texture. As this copy happens per frame, the performance of the entire Flutter UI might be impacted. In Android 10 or above, the graphics memory is copied only once. Virtual display, on the other hand, makes each pixel of the native view flow through additional intermediate graphic buffers, which cost graphic memory and drawing performance. For complex cases, there are some techniques that can be used to mitigate these issues. For example, you could use a placeholder texture while an animation is happening in Dart. In other words, if an animation is slow while a platform view is rendered, then consider taking a screenshot of the native view and rendering it as a texture.
Hybrid Composition Platform Views are rendered as they are normally. Flutter content is rendered into a texture. SurfaceFlinger composes the Flutter content and the platform views.
best performance and fidelity of Android views.
Flutter performance suffers.
FPS of application will be lower.
Certain transformations that can be applied to Flutter widgets will not work when applied to platform views.
Texture Layer (or Texture Layer Hybrid Composition) Platform Views are rendered into a texture. Flutter draws the platform views (via the texture). Flutter content is rendered directly into a Surface.
good performance for Android Views
best performance for Flutter rendering.
all transformations work correctly.
quick scrolling (e.g. a web view) will be janky
SurfaceViews are problematic in this mode and will be moved into a virtual display (breaking a11y)
Text magnifier will break unless Flutter is rendered into a TextureView.
Scrcpy 可以将输入法移动到虚拟显示器的实现方案 1 getWindowManager().setDisplayImePolicy(virtualDisplayId, displayImePolicy);
这个 displayImePolicy 是0, 也就是说某个显示器标记为0则会在这个显示器上展示键盘，如果是1，则会在主显示器上展示键盘
触控板反馈 1.触控板中点进程序的输入窗口，输入法（小键盘）只能被唤醒一次，输入一次以后，再点输入框就没反应了
测试结果
1.Flutter App 通过 Neo 打开，点击输入框无法打开键盘 ❌ 2.其他 App 通过 Neo 打开，能打开键盘 ✅ 3.ADB KIT Debug 模式，点输入框，键盘能弹，Release 模式不能弹，Neo Resize 窗口后，点击又能弹一次 ❌ 4.用 scrcpy 显示对应的 display，点击输入框能弹 ✅ 5.用 adb shell input -d 147 tap 300 300，点击 Neo 内的 Flutter App(ADB KIT)，能弹(关键) ✅
其中3是比较诡异的，猜测是 VD 触发 resize 后，焦点自动切换到了窗口内的 task 上
先理清下思路 在 Neo 的窗口中，渲染的是 Flutter App 还是其他的 App，弹出键盘的行为有差异
可能是 Flutter App 的一些处理导致的，而且很诡异的，Debug 模式的 Flutter App，键盘都能正常弹出，猜想是 Debug 运行的代码执行比较慢，在很玄学的层面，绕开了焦点在多个显示器间切换的问题
Flutter 的虚拟显示器没有焦点，是因为它是普通的应用权限，无法添加VIRTUAL_DISPLAY_FLAG_OWN_FOCUS flag，而 Neo 是 shell 权限，所以并不是 VD 没有焦点，而是焦点不在期望的显示器上
使用 scrcpy 投屏 Neo 中的窗口，点击 Flutter App 输入框，键盘是能弹出的，这个跟 ime_policy 还没关系
测试5验证了这一点
因为此时在于 VD 内的应用交互的时候，并没有同时点击设备的主屏幕，所以此时的焦点就在 VD 上
结论: Neo 点击应用内窗口无法弹出软键盘，是因为事件同时在以下几个地方生效 FlutterView.java#L384C1-L386C35
1 2 3 setFocusable(true ); setFocusableInTouchMode(true );
2.Neo 将这些事件同时下发到了 VD 中
此时的焦点应该会来回在多个显示器间切换
TODO 用 AAS 验证一下
ACTION_DOWN -> FlutterView(Focus) -> InjectEvent(VD) -> VD’s Task(Focus)
1 adb logcat -v time | grep --line-buffered -E "InputMethodManagerService|InputMethodManager|onRequestShow|SHOW_SOFT_INPUT|setImeWindowStatus|displayId|InputDispatcher|WindowManager"
仍然很诡异 下面是使用 Neo 在内置显示器上点击 ADBKIT 的窗口内的输入框
Android 16 软键盘 ✅
Android 15 软键盘 ✅
Android 14 软键盘 ✅
Android 13 软键盘 ✅
使用外置显示器，通过触控板，点击 ADB KIT 窗口内的输入框
Android 16 软键盘 ❌
Android 15 软键盘 ❌
Android 14 软键盘 ❌
Android 13 软键盘 ❌
此时用 scrcpy 直接操作 ADB KIT 所在的显示器，点击输入框
猜测还是焦点导致的
鼠标消失 在 Android 13 模拟器上测试，第二次打开 Neo，鼠标消失，原因是软件其实并没有完全退出，怎么解？
所以只在我一加 Pad2 Pro 上出现？
Neo 点击 Flutter App 日志 1 2 E/WindowManager(3097): isInputMethodClientFocus: display ID mismatch. from client: 106 from window: 0 W/InputMethodManagerService(3097): Ignoring showSoftInput of uid 10315
IME（输入法服务）判断请求来源于 display 106，
scrcpy 点击 Flutter App 日志 scrcpy server 在 该 displayId=106 上注入事件；
同时 焦点窗口（WindowState）与 IME client 的 displayId 一致（都为 106）；
因此 isInputMethodClientFocus() 检查通过，键盘可显示。
1 2 E/WindowManager: isInputMethodClientFocus: display ID mismatch. from client: 111 from window: 0 W/InputMethodManagerService: Ignoring showSoftInput of uid 10288
Neo 点击系统 App 日志，猜测是其他的 App 在唤起软键盘和 Flutter 是不一样的方式，所以在焦点不对的情况下，键盘也能弹出 1 2 3 V/InputMethodManager: Display ID mismatch found. ViewRootImpl displayId=111 InputMethodManager displayId=0. Use the right InputMethodManager instance to avoid performance overhead.
事件原理分析 1 2 3 4 void onRequestShow(InputMethodClient client, int reason, boolean fromUser) { Slog.v(TAG, client + ": onRequestShow at " + origin + " reason " + reasonToString(reason) + " fromUser " + fromUser); }
在 Neo 中点击窗口内应用的输入框
1 com.nightmare.neo:f85ed5fc: onRequestShow at ORIGIN_CLIENT reason SHOW_SOFT_INPUT fromUser false
程序调用的代码
1 InputMethodManager.showSoftInput(view, 0);
AAS 测试结果 通过在一加 Pad2 Pro 上点击 Neo 内部的 ADB KIT 输入框，键盘无法弹出
AAS 的 onTaskFocusChanged 并未回调，也就是说虽然通过 InjectEvent 注入了点击事件，但是焦点并没有切换到 VD 上(很奇怪)
onTaskStackChanged 关键
代码调用 VD Resize 并不触发 onTaskStackChanged
Android 15(模拟器) 点击 ADB KIT

焦点没有发生变化
moveTaskToBack 有没可能可以暂停task
继续 在 Neo Activity 中加入以下代码
1 2 3 4 getWindow().setFlags( WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE );
这个时候，不管是启动 Flutter App 还是其他，通过 adb tap 或者 scrcpy 都无法弹起输入法
所以这个是不是依赖当前 Activity 的焦点？
