真没想到这东西居然还会写到第七篇，很多亲们的反馈和鼓励给了我很大的动力啊，最近正好朋友也在做这个东西，但是我们用一样的库和后端做的东西居然不一样（他用这个做了联网弹幕！），不过确实发现了一些问题比如asmack的库内容参差不齐，很多提供方法都不一样，看来使用者们都或多或少的对源码进行了一些修改，都变得乱糟糟的呢！
这里就提供一下我自己用的asmack库吧，省的大家用的不一样：http://files.cnblogs.com/files/lfkdsk/asmack.zip
这次的博文先从完成的效果开始吧，这个并不是最终稿，因为虽然完成了很多的功能啊，但是还有一些问题，比如接收数据没用广播啊，监听的ChatListener没放在server里啊，好友系统并不完善啊，很多的东西还没有完成，到时候还要根据这些东西进行一些修改，但是现在需要的功能已经够用了，接着的那些东西也不过是要应用asmack库里的东西而已了，好了先上效果图：
（1.首先登录界面增加了Ip的选项，更具有Spark的android版的感觉，通用性强了，不过我之后要是想上线让大家用可能会删掉）
（2.现在不打开具体的聊天窗口，程序也不会蹦了，因为原来是直接向listview里面添加数据，可是listview还没初始化所以会崩）
（3.打开具体的useractivity就会取出原来的数据然后还有新打印的出来的）
（4.信息由于是走数据库了，所以分发也不会想原来一样出错了）
（5.我不想用传统的通知栏，那个用户能禁用，哈哈哈哈哈哈哈，我用了定制的Toast，在桌面的时候接到消息就会弹出一个Toast提示！）
好了这就是我们本次要达成的效果，让我们一个一个来！
1.首先从主界面的输入IP开始：
<TableRow>
<TextView
android:textColor="#ffc2c6c6"
android:layout_height="wrap_content"
android:text="Ip"/>
<EditText
android:id="@+id/login_ip"
android:hint="Input your Ip"
android:maxLines="1"
android:layout_height="wrap_content"
/>
</TableRow>
先在TableLayout里添加。
静态数据类里添加：
//ip名称
public static String My_Ip = "";
主活动的添加：
ip = (EditText) findViewById(R.id.login_ip);
check_init()函数里添加：
private void checkbox_init() {//checkbox判断函数
//判断记住密码多选框的状态
if(sp.getBoolean("ISCHECK", false))
{
//设置默认是记录密码状态
check_save.setChecked(true);
ip.setText(sp.getString("USER_IP", ""));
name.setText(sp.getString("USER_NAME",""));
password.setText(sp.getString("PASSWORD",""));
//判断自动登陆多选框状态
if(sp.getBoolean("AUTO_ISCHECK", false))
{
//设置默认是自动登录状态
check_auto.setChecked(true);
//跳转界面
//account=sp.getString("USER_NAME","");
//pwd=sp.getString("PASSWORD","");
Log.i("======================"+account,pwd+"===================================");
accountLogin();
}
}
}
private void setCheck_save(){
if(check_save.isChecked())
{
//记住用户名、密码、
editor = sp.edit();
editor.putString("USER_IP", user.My_Ip);
editor.putString("USER_NAME", account);
editor.putString("PASSWORD",pwd);
editor.apply();
}
}这个是把Ip添加进记录。
修改登录的方法：
private void accountLogin() {
new Thread() {
public void run() {
user.My_Ip = ((EditText)findViewById(R.id.login_ip))
.getText().toString();
account = ((EditText) findViewById(R.id.login_name))
.getText().toString();
pwd = ((EditText) findViewById(R.id.login_password)).getText()
.toString();
boolean is = ConnecMethod.login(account, pwd);
if (is) {
insHandler.sendEmptyMessage(1);
// 将用户名保存
user.UserName = account+"@lfkdsk/Spark 2.6.3";
user.UserName_= account;
setCheck_save();
} else {
insHandler.sendEmptyMessage(0);
}
}
}.start();
}但是要是逐层的为函数添加参数，然后无限的传参也是一种不太现实的方法，所以我们在XMpp连接的地方直接调用静态存储的IP:
public static boolean openConnection() {
try {
connConfig = new ConnectionConfiguration(user.My_Ip, 5222);
// 设置登录状态为离线
connConfig.setSendPresence(false);
// 断网重连
connConfig.setReconnectionAllowed(true);
con = new XMPPConnection(connConfig);
con.connect();
return true;
} catch (Exception e) {
}
return false;
}这样我们登陆的时候就能手动指定ip或者是域名了，增强了通用性。
2.本地化数据的具体操作：
1.新建一个类作为本地数据库的模版：
package com.lfk.webim.appli; import android.util.Log; /**
* Created by Administrator on 2015/5/26.
*/
public class TalkLogs {
private String ID = "_id"; //数据库主键，自增
private String With_Id ="with_id"; //和谁聊天
private String Logs = "talklogs"; //聊天记录
private String If_read = "_ifread"; //是否已读
private String dbname; //数据表名---为用户名，即user.UserName_
private String CREAT_DB = ""; //数据库新建的语句 public TalkLogs(String dbname){
this.dbname = dbname;
giveanameto(dbname);
Log.e("dbname=====", this.dbname);
Log.e("dbname参数=====",dbname);
}
private void giveanameto(String dbname){
CREAT_DB = "CREATE TABLE if not exists "+dbname+"("
+this.ID +" integer primary key autoincrement,"
+this.With_Id+","
+this.If_read+" integer,"
+ this.Logs+")";
}
public String returnAString(){
Log.e("CREAT_DB===========",CREAT_DB);
return CREAT_DB;
}
}
package com.lfk.webim.appli; import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.widget.Toast; /**
* Created by Administrator on 2015/5/25.
*/
public class SQLiteHelper extends SQLiteOpenHelper {
private Context mcontext;
public SQLiteHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
super(context, name, factory, version);
mcontext = context;
}
@Override
public void onCreate(SQLiteDatabase db) {
//db.execSQL(CREAT_DB);
Toast.makeText(mcontext, "succeed collect！", Toast.LENGTH_SHORT).show();
} @Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
}
写一个空的SQLiteHelper，把表放在后面。
代码里做了详细的注释，类里面传入用户名，返回新建表的String语句。
public void CreateNewTable(){
sqLiteHelper = new SQLiteHelper(this,"user_logs.db",null,1); //新建.db文件
sqLiteDatabase = sqLiteHelper.getWritableDatabase();
TalkLogs talklog = new TalkLogs(user.UserName_); //获取新建表的语句
sqLiteDatabase.execSQL(talklog.returnAString()); //新建表
Toast.makeText(friend.this, user.UserName_+" Create success",Toast.LENGTH_SHORT).show();
Log.e(user.UserName_, "success!!!");
//sqLiteDatabase.close();
}在friend的activity里面，新建该方法，每次进入朋友界面，新建以用户名为名的表，因为用的SQL语句写了if exist 所以已有的不会新建。
final ClientConServer server = new ClientConServer(this,mhandler,this.sqLiteDatabase);
对工具类进行实例化，可以解决静态方法不能用在非静态上下文的问题，这里传入context，handler，和数据库，数据库是为了防止打开重复，传入handler是为了桌面Toast

for(ResolveInfo ri : resolveInfo){
names.add(ri.activityInfo.packageName);
System.out.println(ri.activityInfo.packageName);
}
return names;
}
}3.3判断现在栈顶的活动是什么？还有是否在桌面。
3.4消息的分发机制
这里需要讲解一下我的聊天机制，ChatListener接收数据，然后存入数据库，如果现在的栈顶活动为朋友界面（有一个判断），就默默的存进去，如果是聊天界面就把所有数据库里的取出来，把所有的消息都设为已读（_ifread=1），放在listview里，
然后如果有新消息的话,就用3.1的方法把所有的_ifread的消息取出来，即时的显示在listview里面，如果现在为桌面，就把东西存入然后再Toast出来。
所以handler就是重要的消息分发机制：
private Handler handler = new Handler(){
public void handleMessage(android.os.Message m) {
Message msg = new Message();
msg = (Message) m.obj;
//把从服务器获得的消息通过发送
String[] message = new String[]{ msg.getFrom(), msg.getBody()};
System.out.println("==========收到消息 From==========="+ message[0]);
System.out.println("==========收到消息 Body===========" + message[1]);
String s = msg.getFrom();
String s1 = s.split("@")[0];
ContentValues values = new ContentValues();
if(message[1]!=null) {
if (user.UserName.equals(message[0])) {
values.put("with_id",s1);
values.put("talklogs", "ME: " + msg.getBody());
values.put("_ifread",0);
Log.e("存入：", "ME: " + msg.getBody());
sqLiteDatabase.insert("\"" + user.UserName_ + "\"", null, values);
values.clear();
} else {
values.put("with_id", s1);
values.put("talklogs", s1 + "说：" + msg.getBody());
values.put("_ifread", 0);
Log.e("存入：", s1 + "说：" + msg.getBody());
sqLiteDatabase.insert("\"" + user.UserName_ + "\"", null, values);
addUnread(values,s1);
}
if(isHome(context)){
sendToast(msg,s1);
}
}
}

database.execSQL("UPDATE "+user.UserName_+" SET _ifread = 1 "+"Where with_id ="+"\""+user.FromName_+"\"");

//database.close();

public static boolean checkColumnExist1(SQLiteDatabase db, String tableName, String columnName) {

聊天活动
private void OpenDatabase(){
String DB_NAME = "user_logs.db"; //保存的数据库文件名
String PACKAGE_NAME = "com.lfk.webim";// 应用的包名
String DB_PATH = "/data"
+ Environment.getDataDirectory().getAbsolutePath() +"/"
+ PACKAGE_NAME+ "/databases"; // 在手机里存放数据库的位置
File myDataPath = new File(DB_PATH);
String dbfile = myDataPath+"/"+DB_NAME;
database = SQLiteDatabase.openOrCreateDatabase(dbfile, null);
if(!checkColumnExist1(database,user.UserName_,user.FromName_)){
Cursor cursor = database.rawQuery("Select * From "+user.UserName_+" where with_id ="+"\""+user.FromName_+"\"",null);
if(cursor.moveToFirst()) {
do {
String talklogs = cursor.getString(cursor.getColumnIndex("talklogs"));
mConversationArrayAdapter.add(talklogs);
Log.e(talklogs, "================");
}while (cursor.moveToNext());
}
database.execSQL("UPDATE "+user.UserName_+" SET _ifread = 1 "+"Where with_id ="+"\""+user.FromName_+"\"");
cursor.close();
//database.close();
}
}每次进入都先打开数据库，并且把所有的聊天对应的人的数据库信息取出来，然后把所有的已读标志设为1；
public static boolean checkColumnExist1(SQLiteDatabase db, String tableName, String columnName) {
boolean result = false ;
Cursor cursor = null ;
try{
//查询一行
cursor = db.rawQuery( "SELECT * FROM " + tableName + " LIMIT 0", null );
result = cursor != null && cursor.getColumnIndex(columnName) != -1 ;
}catch (Exception e){
Log.e("","checkColumnExists1..." + e.getMessage()) ;
}finally{
if(null != cursor && !cursor.isClosed()){
cursor.close() ;
}
}
return result ;
}这里用到了一个方法，用来判断表里有没有你的这个字段，如果没有就不用添加到listview里，否则你没和他聊过会崩！！
public Handler mhandle = new Handler() {
public void handleMessage(android.os.Message m) {
switch (m.what) {
case 1:
Toast.makeText(useractivity.this, "不能发送空消息", Toast.LENGTH_SHORT).show();
break;
case 0:
String respond = (String) m.obj;
Log.i("---", respond);
ContentValues values = new ContentValues();
values.put("with_id",user.FromName_);
values.put("talklogs","ME: "+respond);
values.put("_ifread",0);
Log.e("存入：", "ME: " + respond);
database.insert("\"" + user.UserName_ + "\"", null, values);
values.clear();
mConversationArrayAdapter.add("ME: "+respond);
mConversationArrayAdapter.notifyDataSetChanged();
break;
case 2:
//addTheListview();
break;
}
}
};在自己发送消息的时候，存入数据库，然后添加到listview里面。
3.桌面显示的Toast:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/llToast"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffffff"
android:orientation="vertical" > <TextView
android:id="@+id/tvTitleToast"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="1dip"
android:background="#bb000000"
android:gravity="center"
android:text="Title"
android:textColor="#ffffffff" /> <LinearLayout
android:id="@+id/llToastContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="1dip"
android:layout_marginLeft="1dip"
android:layout_marginRight="1dip"
android:background="#44000000"
android:orientation="vertical"
android:padding="15dip" > <ImageView
android:id="@+id/tvImageToast"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:contentDescription="@string/hello_world"
android:src="@drawable/toast_image" /> <TextView
android:id="@+id/tvTextToast"
android:layout_width="128dp"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:singleLine="false"
android:text="自定义显示语句"
android:textColor="#ff000000" />
</LinearLayout> </LinearLayout>
1.添加一个toast的布局文件，写出来的样子是这样的：
2.friend里面添加一个方法进行处理：
public void showCustomToast(String s1, String s2) {//新建显示TOAST
// 通用的布局加载器
LayoutInflater inflater = getLayoutInflater();
// 加载根容器，方便用于后面的view的定位
View layout = inflater.inflate(R.layout.toast_view, (ViewGroup)findViewById(R.id.llToast));
// 设置图片的源文件
ImageView image = (ImageView) layout.findViewById(R.id.tvImageToast);
image.setImageResource(R.drawable.toast_image);
// 设置title及内容
TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
title.setText(s1);
TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
text.setText(s2);
Toast tempToast = new Toast(getApplicationContext());
// 设置位置
tempToast.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER, 0, 0);
// 设置显示时间
tempToast.setDuration(Toast.LENGTH_SHORT);
tempToast.setView(layout);
tempToast.show();
}
}3.显示：
刚才在friend里面我们对工具类进行了实例化，传入了handler，就是要在工具类用handler回调，用friend的handler进行处理：
if(isHome(context)){
sendToast(msg,s1);
}如果在桌面：
private void sendToast(Message msg,String s1){
android.os.Message message_send = new android.os.Message();
Bundle bundle = new Bundle();
bundle.putString("name",s1);
bundle.putString("text",msg.getBody());
message_send.obj = bundle;
message_send.what = 0;
handlers.sendMessage(message_send);
}打包名字，信息发到friend的handler里去。
public Handler mhandler = new Handler()
{
public void handleMessage(android.os.Message message)
{
switch (message.what) {
case 0:
Bundle bundle = (Bundle)message.obj; //桌面Toast的解决方法
String s1 = bundle.getString("name");
String s2 = bundle.getString("text");
showCustomToast(s1,s2);
break;
case 1: {
String temp = (String) message.obj;
friend.mArrayAdapter.add(temp);
break;
}
}
}
};
friend的Handler里处理一下，就能显示出来了。
这一次就说这么多吧，整个Demo已经能像正常的IM应用一样使用了，还有一些自己的修改方法，在下一篇的后续里会增加加好友啊，
加组，转入server里的一系列方法，敬请期待！
