在com.android.commands.input中发现这一方法

view plaincopy to clipboardprint?

private void sendKeyEvent(String event) {

int eventCode = Integer.parseInt(event);

long now = SystemClock.uptimeMillis();

Log.i("SendKeyEvent", event);

try {

KeyEvent down = new KeyEvent(now, now, KeyEvent.ACTION_DOWN, eventCode, 0);

KeyEvent up = new KeyEvent(now, now, KeyEvent.ACTION_UP, eventCode, 0);

(IWindowManager.Stub

.asInterface(ServiceManager.getService("window")))

.injectKeyEvent(down, true);

(IWindowManager.Stub

.asInterface(ServiceManager.getService("window")))

.injectKeyEvent(up, true);

} catch (RemoteException e) {

Log.i("Input", "DeadOjbectException");

}

}

private void sendKeyEvent(String event) {

int eventCode = Integer.parseInt(event);

long now = SystemClock.uptimeMillis();

Log.i("SendKeyEvent", event);

try {

KeyEvent down = new KeyEvent(now, now, KeyEvent.ACTION_DOWN, eventCode, 0);

KeyEvent up = new KeyEvent(now, now, KeyEvent.ACTION_UP, eventCode, 0);

(IWindowManager.Stub

.asInterface(ServiceManager.getService("window")))

.injectKeyEvent(down, true);

(IWindowManager.Stub

.asInterface(ServiceManager.getService("window")))

.injectKeyEvent(up, true);

} catch (RemoteException e) {

Log.i("Input", "DeadOjbectException");

}

}

injectKeyEvent是WindowManagerService的public 方法，虽然WindowManagerService被隐藏掉，但是我们可以通过反射来调用injectKeyEvent。
