How do i get new position value during drag and drop in RecyclerView adapter? Drag and Drop is working perfect but when i set setOnClickListener to open my detail activity. it gives me the old position value. For example : If i drag 2nd item (INDEX 1) and drop at 1st item's position (INDEX 0). On debuging inside setOnClickListener when i am calling Intent. Position value is 1 (INDEX 1) but what i need is value 0 (INDEX 0). @Override public void onBindViewHolder(final ItemViewHolder holder, final int position) { holder.textView.setOnClickListener(new View.OnClickListener() { @Override public

I am new here and just learning python. I need help to get the right mac-address of my network card in windows using python.

I was searching for a while but i couldn't find the solution. Situation: I'm using a ListView and I have in a Cursor the result of a SQLiteDatabase.query. If I use a SimpleCursorAdapter , when you call onItemClick(AdapterView<?> parent, View view, int position, long id) , the id returned is the _id of the row of the given Cursor but if I use a custom Adapter the return id works like an array [0,1,2,3], how can I set in the custom Adapter this id? Thanks Adapter has a method that you can override, called getItemId(int pos) . Just return whatever id you need for a given item position and it will

People claim the following VB script works for changing network adapter names. However I am having a decidedly difficult time trying to convert this to a c# appliaction that can do the same thing. The problem I seem to be facing is that calls to the NetworkInterface.Name is readonly. Option Explicit Const NETWORK_CONNECTIONS = &H31& Dim sOldName= WScript.Arguments(0) Dim sNewName= WScript.Arguments(1) Dim objShell, objFolder, colItems, objItem Set objShell = CreateObject("Shell.Application") Set objFolder = objShell.Namespace(NETWORK_CONNECTIONS) Set colItems = objFolder.Items For Each objItem

集合 有了数组为什么还要集合： 数组是固定长度的，集合长度可变（因此，适应场景不同） 同时存储一对一关系的数据 方便增删改查 不能添加重复数据（如set中） Collection Map 接口 HashMap List Queue Set ArrayList LinkedList HashSet 类 Collection存储类的对象，Map存储键值对。 List和Queue存储的对象是有序的，允许重复的，可以为null；Set中存储的对象是无序的，不允许重复的，只能有一个为null。 ArrayList l ArrayList底层是由数组实现的 l 可以动态增长 l 列表尾部添加或删除元素效率高（在中间插入或删除元素需要移动后面的元素） l 更适合查找或更新元素 l 元素可以为NULL add() 插入元素 size() 查看元素个数，遍历输出元素 remove() 移除元素 （remove（“dd”）只会移除一个） 用removeAll（Collection）可以删除所有 HashSet l Set是元素无序，并且不可以重复的集合，称为集 l HashSet是Set的一个重要的实现类 l HashSet只允许有一个Null值 l 具有良好的存取及查找性能 Iterator（迭代器） Iterator接口可以以统一的方式对各种集合元素进行遍历 hasNext（

I am trying to implement a grid of images. I have done that in an activity by referring to this link. Now, if I try to implement the same thing in a class which extends Fragment, I have done this package com.example.emergency1; import android.content.Context; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.webkit.WebView.FindListener; import android.widget.GridView; public class City1 extends Fragment { public static Fragment newInstance(Context context) { City1 f = new

I need to create an AlertDialog with multiple choice items but I'm having some trouble trying to set a custom layout file to the internal ListView. For single choice items I use a constructor that takes a ListAdapter as parameter and this way I can set the proper layout resource for each row: builder.setSingleChoiceItems(new ArrayAdapter<String>(getActivity(), R.layout.list_item_single_choice_answer, items), checkedItem, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { checkedItem = which; toggleEditTextAnswer(checkedItem == (items
