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

package io.appium.android.bootstrap.handler;

import android.os.SystemClock;

import android.view.InputDevice;

import android.view.InputEvent;

import android.view.KeyCharacterMap;

import android.view.KeyEvent;

import com.android.uiautomator.common.ReflectionUtils;

import io.appium.android.bootstrap.AndroidCommand;

import io.appium.android.bootstrap.AndroidCommandResult;

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.

* bootstrap.AndroidCommand)

*/

@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);

} catch (final Exception e) {

return getErrorResult(e.getMessage());

}

}

}

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。
