Android programming implementation of Bubble Chat interface examples (with source code) _android

This article illustrates the method of Android programming to realize the bubble chat interface. Share to everyone for your reference, specific as follows:

Yesterday I wrote an interface to implement the Android bubble chat interface. The results of the operation are as follows, click the Send button, the screen will display text content.

I am also a source on the web based on the changes, the entire bubble interface to achieve the main points:

(1) The main interface is actually a list View

(2) The text display interface actually uses the android:background= "@drawable/incoming" this thing. The format of the background picture is xxx.9.png, specifically for scaling, otherwise the display effect is very poor.

(3) A custom adapter, of course, is inherited Android.widget.BaseAdapter, rewrite the GetView method.

The whole project is distributed as follows:

The main activity:chatactivity are as follows:

Package com.tencent; 
Import android.app.Activity; 
Import Android.os.Bundle; 
Import Android.util.Log; 
Import Android.view.View; 
Import Android.view.View.OnClickListener; 
Import Android.widget.Button; 
Import Android.widget.EditText; 
Import Android.widget.ListView; 
Import java.util.ArrayList; 
Import Java.util.Calendar; 
  public class Chatactivity extends activity {private static final String TAG = ChatActivity.class.getSimpleName ();; 
  Private ListView Talkview; 
  Private Button Messagebutton; 
  Private EditText MessageText; 
  Private Chatmsgviewadapter Myadapter; 
  Private arraylist<chatmsgentity> list = new arraylist<chatmsgentity> (); 
    public void OnCreate (Bundle savedinstancestate) {log.v (TAG, "OnCreate >>>>>>"); 
    Super.oncreate (savedinstancestate); 
    Setcontentview (R.layout.main); 
    Talkview = (ListView) Findviewbyid (r.id.list); 
    Messagebutton = (Button) Findviewbyid (R.id.messagebutton); MessageText = (EditText) Findviewbyid (R.id.messagetext); 
        Onclicklistener Messagebuttonlistener = new Onclicklistener () {@Override public void OnClick (View arg0) { 
        TODO auto-generated Method Stub log.v (TAG, "onclick >>>>>>>>"); 
        String name = GetName (); 
        String date = GetDate (); 
        String Msgtext = GetText (); 
        int RId = R.layout.list_say_he_item; 
        Chatmsgentity newmessage = new Chatmsgentity (name, date, Msgtext, RId); 
        List.add (Newmessage); 
        List.add (D0); 
        Talkview.setadapter (New Chatmsgviewadapter (Chatactivity.this, list)); 
        Messagetext.settext (""); 
      Myadapter.notifydatasetchanged (); 
    } 
    }; 
  Messagebutton.setonclicklistener (Messagebuttonlistener); }//Shuold be redefine to future private String GetName () {return getresources (). getString (R.string.mydis 
  Playname); }//Shuold be redefine in the future private String geTdate () {Calendar c = calendar.getinstance (); String date = string.valueof (C.get (calendar.year)) + "-" + string.valueof (C.get (calendar.month)) + "-" + C.get (c. 
    Get (Calendar.day_of_month)); 
  return date; 
  }//Shuold be redefine to future private String GetText () {return Messagetext.gettext (). toString (); 
    public void OnDestroy () {LOG.V (TAG, "ondestroy>>>>>>"); 
    list = null; 
  Super.ondestroy ();

 } 
}

Display the definition of the body of a message

 package com.tencent; 
  public class Chatmsgentity {private static final String TAG = ChatMsgEntity.class.getSimpleName (); 
  private String name; 
  Private String date; 
  private String text; 
  private int layoutid; 
  Public String GetName () {return name; 
  public void SetName (String name) {this.name = name; 
  Public String GetDate () {return date; 
  public void setdate (String date) {this.date = date; 
  Public String GetText () {return text; 
  public void SetText (String text) {this.text = text; 
  public int Getlayoutid () {return layoutid; 
  The public void Setlayoutid (int layoutid) {this.layoutid = LayoutID; Public chatmsgentity () {} public chatmsgentity (string name, string date, string text, int layoutid) {Supe 
    R (); 
    THIS.name = name; 
    This.date = date; 
    This.text = text; 
  This.layoutid = LayoutID; } 
}

The

Chatmsgviewadapter is defined as follows:

    chatmsgentity entity = coll.get (position); 
    int itemlayout = Entity.getlayoutid (); 
    LinearLayout layout = new LinearLayout (CTX); 
    Layoutinflater VI = (layoutinflater) ctx.getsystemservice (Context.layout_inflater_service); 
    Vi.inflate (itemlayout, layout, true); 
    TextView tvname = (TextView) Layout.findviewbyid (r.id.messagedetail_row_name); 
    Tvname.settext (Entity.getname ()); 
    TextView tvdate = (TextView) Layout.findviewbyid (r.id.messagedetail_row_date); 
    Tvdate.settext (Entity.getdate ()); 
    TextView Tvtext = (TextView) Layout.findviewbyid (R.id.messagedetail_row_text); 
    Tvtext.settext (Entity.gettext ()); 
  return layout;

  public Boolean IsEmpty () {return false; The public void Registerdatasetobserver (Datasetobserver observer) {} is public void Unregisterdatasetobserver (DataSet

Layout file See me more painful, this layout file is not good, hehe
