hi粉丝朋友们 近期有个学员问到了一个输入法相关问题。刚好梳理了一下输入法相关的在多屏模式的一个展示流程这里做个记录也相当于深入理解窗口相关的一篇干货blog。 如上面两幅图展示输入法可以自由自在显示在双屏的任意屏幕那么下面主要就是来解密输入到底如何做到的自由双屏展示。
分析思路
如果对输入相关业务不知道的话那么就只能考虑从窗口层面入手一般输入法都是其实是一个dialog这个类是SoftInputWindow 一般输入法窗口显示到了其他屏幕肯定相关的displayid是要变化的这里可以dumpsys window windows可以看出来 输入法窗口在副屏

这里可以考虑在SoftInputWindow的构造方法中加入相关堆栈。
日志堆栈及源码
上一个屏幕的输入法移除
systemserver发起inputmethodservice的destory

execTransactInternal:1280, Binder (android.os)
execTransact:1244, Binder (android.os)这里可以看出主要是一个跨进程调用发起老的输入法service要stopdestory新的service要进行onCreate这些堆栈都是在systemserver进程打出来的。 是谁发起跨进程startInputOrWindowGainedFocus方法呢当然是app端啊输入焦点EditText那个app
App端发起启动输入法
startInputInner:2379, InputMethodManager (android.view.inputmethod)

startInputAsyncOnWindowFocusGain:733, InputMethodManager$DelegateImpl (android.view.inputmethod)

invoke:-1, Method (java.lang.reflect)
run:548, RuntimeInit$MethodAndArgsCaller (com.android.internal.os)
main:936, ZygoteInit (com.android.internal.os)
可以看到在app ViewRootImpl的handleWindowFocusChanged() 方法发起的操作
SoftInputWindow创建堆栈
LatinIME这个service的onCreate创建
init:135, SoftInputWindow (android.inputmethodservice)
onCreate:1515, InputMethodService (android.inputmethodservice)
onCreate:608, LatinIME (com.android.inputmethod.latin)
handleCreateService:4515, ActivityThread (android.app)
-$$Nest$mhandleCreateService:-1, ActivityThread (android.app)
handleMessage:2162, ActivityThread$H (android.app)
dispatchMessage:106, Handler (android.os)
loopOnce:201, Looper (android.os)
loop:288, Looper (android.os)
main:7898, ActivityThread (android.app)
invoke:-1, Method (java.lang.reflect)
run:548, RuntimeInit$MethodAndArgsCaller (com.android.internal.os)
main:936, ZygoteInit (com.android.internal.os)创建SoftInputWindow的Display确定
相关创建SoftInputWindow代码关键的是这个context看看这个context的创建流程
frameworks/base/core/java/android/app/ActivityThread.java UnsupportedAppUsageprivate void handleCreateService(CreateServiceData data) {
//省略大部分ContextImpl context ContextImpl.getImpl(service.createServiceBaseContext(this, packageInfo));}调用到了createServiceBaseContext方法
frameworks/base/core/java/android/window/WindowProviderService.java
/** hide */
Override
public final Context createServiceBaseContext(ActivityThread mainThread,LoadedApk packageInfo) {final Context context super.createServiceBaseContext(mainThread, packageInfo);final Display display context.getSystemService(DisplayManager.class).getDisplay(getInitialDisplayId());//这里是核心关键会创建displayreturn context.createTokenContext(mWindowToken, display);
}这里可以看到主要核心就是context.getSystemService(DisplayManager.class) .getDisplay(getInitialDisplayId())获取一个display这个display也就是最后决定输入在哪个屏幕的关键 这里主要通过getInitialDisplayId获取到合适的displayId
frameworks/base/core/java/android/inputmethodservice/AbstractInputMethodService.java /** hide */Overridepublic final int getInitialDisplayId() {try {//这里主要调用到wms的getImeDisplayIdreturn WindowManagerGlobal.getWindowManagerService().getImeDisplayId();} catch (RemoteException e) {throw e.rethrowFromSystemServer();}}下面看看wms的getImeDisplayId frameworks/base/services/core/java/com/android/server/wm/WindowManagerService.java
Overridepublic int getImeDisplayId() {synchronized (mGlobalLock) {//这里主要获取一下焦点的Display是谁final DisplayContent dc mRoot.getTopFocusedDisplayContent();//这里有个getImePolicy获取要等于DISPLAY_IME_POLICY_LOCAL才可以return dc.getImePolicy() DISPLAY_IME_POLICY_LOCAL ? dc.getDisplayId(): DEFAULT_DISPLAY;}}那现在就清楚了输入法显示在哪个Display是最后调用到了wms的中的getImeDisplayId方法这个方法主要就是获取当前谁是focused的display然后把displayid传递回去
总结
整个多屏输入法的流程涉及到了3个进程 ----焦点app发起startInputAsyncOnWindowFocusGain------systemserver stop老的servicestart新service--------输入法进程创建新的service onCreate执行-------输入法创建带有display的context--------创建对于输入法窗口带有新的display更多framework干货获取相关可以 私聊v(androidframework007) 点击这里 https://mp.weixin.qq.com/s/Qv8zjgQ0CkalKmvi8tMGaw 视频https://www.bilibili.com/video/BV1ah411d7Y3
