Android imitation QQ sliding pop-up menu Mark Read, unread message _android

In the previous "Android imitation micro-letter sliding pop-up Edit, delete menu effect, add Drop-down refresh function" , has taken you to learn how to use Swipemenulistview this open source library to implement the slide list pop-up menu, next, will further study, How to present different menu for different list item, here we do an example: Android high imitation qq sliding pop-up menu Mark read, unread message, look at the effect of the picture:

1. Create the project and import the Swipemenulistview class library

2. Create a message entity bean:

public class MSG {public 
 
  int id; 
 
  public String title; 
 
  Public String desc; 
 
  False is unread; True is read public 
  boolean isread; 
 
  @Override public 
  String toString () {return 
    "msg{" + 
        "id=" + ID + 
        ", title= '" + title + ' \ ' + 
        ", desc= ' "+ desc + ' \ ' + 
        ", isread= "+ Isread + 
        '} '; 
  } 
} 

Note: Through the Isread field, we distinguish the menu display "set as read" "Set to Unread";

3. Create the adapter of the list display, overriding the Getitemviewtype method:

Import android.app.Activity; 
Import Android.view.LayoutInflater; 
Import Android.view.View; 
Import Android.view.ViewGroup; 
Import Android.widget.BaseAdapter; 
Import Android.widget.ImageView; 
 
Import Android.widget.TextView; 
 
Import java.util.List; 
 
  /** * My msgs list adapter/public class Mymsgadapter extends Baseadapter {private activity mcontext; 
 
  Private Layoutinflater Minflater; 
 
  Private list<msg> Mdatas; 
    Public Mymsgadapter (activity context, list<msg> datas) {mcontext = context; 
    Minflater = Layoutinflater.from (Mcontext); 
  Mdatas = datas; 
  @Override public int GetCount () {Mdatas!= null? Mdatas.size (): 0); 
  @Override public Object getitem (int position) {return (Mdatas!= null mdatas.get (position): null); 
  @Override public long getitemid (int position) {return position; 
  @Override public int Getviewtypecount () {return 2; } @Override public int Getitemviewtype (int position) {MSG mymsg = mdatas.get (position); 
    Boolean isread = Mymsg.isread; 
    if (isread) {return 0; 
    else {return 1; } @Override Public View getview (final int position, View Convertview, ViewGroup parent) {Viewholder hol 
    Der = null; 
 
      if (Convertview = = null) {//dropdown item Layout Convertview = Minflater.inflate (r.layout.list_item_my_msg, NULL); 
 
      Holder = new Viewholder (); 
      Holder.img_msg = (ImageView) Convertview.findviewbyid (r.id.img_msg); 
      Holder.text_msg_user_name = (TextView) Convertview.findviewbyid (r.id.text_msg_user_name); 
 
      Holder.text_msg_infos = (TextView) Convertview.findviewbyid (R.id.text_msg_infos); 
 
    Convertview.settag (holder); 
    else {holder = (Viewholder) convertview.gettag (); 
 
    Final MSG mymsg = mdatas.get (position); if (mymsg!= null) {if (Mymsg.isread) {//unread Holder.img_msg.setImageREsource (R.MIPMAP.READED_MSG_IMG); 
      else {holder.img_msg.setImageResource (r.mipmap.unread_msg_img); 
      } holder.text_msg_user_name.setText (Mymsg.title); 
    Holder.text_msg_infos.setText (MYMSG.DESC); 
  return convertview; 
 
    Class Viewholder {ImageView img_msg; 
 
    TextView Text_msg_user_name; 
  TextView Text_msg_infos; 
 } 
}

Note: Here we rewrite the Getitemviewtype method in the parent class, in which we judge whether the return value is 0 or 1 according to the Isread field of MSG, and then we will determine the type of menu for the list item according to the return value.

4. According to Itemviewtype, create a sliding menu:

    Butterknife.bind (this); 
 
    msgs = new arraylist<msg> (); 
    msg MSG1 = new msg (); 
    Msg1.id = 1; 
    Msg1.title = "upper evil"; 
    Msg1.desc = "I want to have a friend with you, a long and no failure"; 
 
    Msg1.isread = false; 
    msg MSG2 = new msg (); 
    Msg2.id = 2; 
    Msg2.title = "Love in the memory to find you"; 
    Msg2.desc = "If can hate you, full of hate you, even meet also want to avoid"; 
 
    Msg2.isread = true; 
    Msgs.add (MSG1); 
 
    Msgs.add (MSG2); 
    Msgadapter = new Mymsgadapter (this, msgs); 
 
    Listviewmymsgs.setadapter (Msgadapter); 
  CreateMenu (); /** * Delete a message * * @param position * * private void deletemsg (int position) {//Dodeletemsgre

      if (omymsg!= null) {msgs.get (position). Isread =!msgs.get (position). Isread; 
    Msgadapter.notifydatasetchanged (); } private void CreateMenu () {//step 1. Create a menucreator swipemenucreator creator = new Swipemenu 
          Creator () {@Override public void Create (Swipemenu menu) {switch (Menu.getviewtype ()) { 
            Case 0://Unread createMenu1 (menu); 
          Break 
            Case 1://has been read createMenu2 (menu); 
        Break 
            } private void CreateMenu1 (Swipemenu menu) {Swipemenuitem Unreaditem = new Swipemenuitem ( 
        Getapplicationcontext ()); UnReaditem.setid (1); 
        Unreaditem.setbackground (New Colordrawable (Color.parsecolor ("#555555")); 
        Unreaditem.setwidth (DP2PX (90));

      Menu.addmenuitem (DeleteItem); 
            } private void CreateMenu2 (Swipemenu menu) {Swipemenuitem Readeditem = new Swipemenuitem ( 
        Getapplicationcontext ());

      Menu.addmenuitem (DeleteItem); 
    } 
    }; 
 
    Set creator Listviewmymsgs.setmenucreator (creator); Step 2. Listener Item Click event Listviewmymsgs.setonmenuitemclicklistener (New Swipemenulistview.onmenuitemclicklistener () {@Override public boolean onmenuitemclick (int position, swipemenu menu, int index) {SWIPEMenuItem MenuItem = Menu.getmenuitem (index); 
        int id = Menuitem.getid (); 
            Switch (ID) {Case 0:logutils.e ("Delete:" + position); 
            DeleteMsg (position); 
          Break 
            Case 1:LOGUTILS.E ("Mark unread:" + position); 
            Readmsg (position); 
          Break 
            Case 2:LOGUTILS.E ("marked as read:" + position); 
            Readmsg (position); 
        Break 
      return false; 
  } 
    }); 
              @OnItemClick (R.ID.LISTVIEWMYMSGS) public void Onitemclick (adapterview<?> parent, view view, int position, 
    Long id) {msg mymsg = (msg) parent.getadapter (). GetItem (position); 
      if (mymsg!= null) {if (Mymsg.isread) {//If it is unread, it needs to be marked as read readmsg (position); }} private int dp2px (int dp) {return (int) typedvalue.applydimension (Typedvalue.complex_unit_dip, DP , Getresources (). GetdisplaymetrICS ()); 
 } 
}

Note: focus on the public void Create (Swipemenu menu) method in the Swipemenucreator interface, through the Menu.getviewtype () method, we can get the list Item ViewType, and this viewtype, so that we just defined ourselves in adapter, so at this point, just have to judge their own defined viewtype values, and according to ViewType to create a menu!

And so on, you can achieve similar QQ sliding pop-up menu tags have been read, unread message function, I hope you like.
