有的时候手机键盘的一些键需要按，但是又没有像pressBack这种方法供我们直接调用，这个时候我们就需要发送键盘的keycode来模拟这些键被点击。所以PressKeyCode就是封装这类事件的，通过上面的代码可以看出，发送keycode分2类事件，每一类调用的方法不一样
- 单点键：pressKeyCode(keyCode,metaState)
- 组合键: pressKeyCode(keyCode,metaState)
LongPressKeyCode

import io.appium.android.bootstrap.CommandHandler;
import org.json.JSONException;
import org.json.JSONObject;
import java.lang.reflect.Method;
import java.util.Hashtable;
/**
* This handler is used to LongPressKeyCode.

public class LongPressKeyCode extends CommandHandler {
public Integer keyCode;
public Integer metaState;
/*
* @param command The {@link AndroidCommand} used for this handler.
*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.

*/
@Override
public AndroidCommandResult execute(final AndroidCommand command)
throws JSONException {
try {
final ReflectionUtils utils = new ReflectionUtils();
final Method injectEventSync = utils.getControllerMethod("injectEventSync",
InputEvent.class);
final Hashtable<String, Object> params = command.params();
keyCode = (Integer) params.get("keycode");
metaState = params.get("metastate") != JSONObject.NULL ? (Integer) params
.get("metastate") : 0;
final long eventTime = SystemClock.uptimeMillis();
// Send an initial down event
final KeyEvent downEvent = new KeyEvent(eventTime, eventTime,
KeyEvent.ACTION_DOWN, keyCode, 0, metaState,
KeyCharacterMap.VIRTUAL_KEYBOARD, 0, 0, InputDevice.SOURCE_KEYBOARD);
if ((Boolean) injectEventSync.invoke(utils.getController(), downEvent)) {
// Send a repeat event. This will cause the FLAG_LONG_PRESS to be set.
final KeyEvent repeatEvent = KeyEvent.changeTimeRepeat(downEvent,
eventTime, 1);
injectEventSync.invoke(utils.getController(), repeatEvent);
// Finally, send the up event
final KeyEvent upEvent = new KeyEvent(eventTime, eventTime,
KeyEvent.ACTION_UP, keyCode, 0, metaState,
KeyCharacterMap.VIRTUAL_KEYBOARD, 0, 0, InputDevice.SOURCE_KEYBOARD);
injectEventSync.invoke(utils.getController(), upEvent);
}
return getSuccessResult(true);

长点击某个键盘键，和上面的单击是有区别的，因为没有直接的API可以调用，所以又要用到反射来做这件事，这次的反射呢调用的是InteractionController中的injectEventSync方法，首先会执行ACTION_DOWN,然后在一段时间里会重复执行这个down的动作，等事件到了以后，执行ACTION_UP这个动作松开键盘键。从而达到了我们到长按到要求。
