修改了引擎CocosCreator\resources\cocos2d-x\cocos\platform\android\java\src\org\cocos2dx\lib下的Cocos2dxEditBoxHelper.java文件，和C:\CocosCreator\resources\cocos2d-x\cocos\ui\edit-box下的EditBox-android.cpp文件
EditBox-android.cpp加4个参数就好了，感谢引擎组没把接口赶尽杀绝

void EditBox::show(const cocos2d::EditBox::ShowInfo& showInfo)
{
JniHelper::callStaticVoidMethod(JCLS_EDITBOX,
“showNative”,
showInfo.defaultValue,
showInfo.maxLength,
showInfo.isMultiline,
showInfo.confirmHold,
showInfo.confirmType,
showInfo.inputType,
showInfo.x,
showInfo.y,
showInfo.width,
showInfo.height);
}

Cocos2dxEditBoxHelper.java改动稍微有点大，直接全粘上好了，引擎原来的并没有删只是注释掉了
