key event 的注入程式： input
source code 在
frameworks/base/cmds/input/src/com/android/commands/input
是一個 java 程式，要用 dalvik run 起來，所以附一個 run script:
在
frameworks/base/cmds/input
# Script to start "input" on the device, which has a very rudimentary
# shell.
#
base=/system
export CLASSPATH=$base/framework/input.jar
exec app_process $base/bin com.android.commands.input.Input $*
使用方法看 source code:
String command = args[0];
if (command.equals("text")) {
sendText(args[1]);
} else if (command.equals("keyevent")) {
sendKeyEvent(args[1]);
} else if (command.equals("motionevent")) {
System.err.println("Error: motionevent not yet supported.");
return;
}
支援 text 和 keyevent 。
keyevent 的話..
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");
}
}
就是把 event code 寫在後面：
#input keyevent code
.. 那 code 的 mapping 呢？
