在Android应用里发送按键

在Android的应用程序里发送按键码值，可以用于模拟按键，这样方便我们实现一些测试工具，实现APK按键功能测试等。

方法/步骤

调用input命令：

try{

            String keyCommand = "input keyevent " + KeyEvent.KEYCODE_1;

            Runtime runtime = Runtime.getRuntime();

            Process proc = runtime.exec(keyCommand);

} catch(IOException e){

}

调用API：

long now = SystemClock.uptimeMillis();

KeyEvent down = new KeyEvent(now, now, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_1, 0);

InputManager.getInstance().injectInputEvent(down, InputManager.INJECT_INPUT_EVENT_MODE_ASYNC);

KeyEvent up = new KeyEvent(now, now, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_1, 0);

InputManager.getInstance().injectInputEvent(up, InputManager.INJECT_INPUT_EVENT_MODE_ASYNC);

在线程里执行如下操作：

Instrumentation mInst = new Instrumentation();

mInst.sendKeyDownUpSync(KeyEvent.KEYCODE_1);
