Android-IM即時通訊:環信
阿新 • • 發佈:2019-01-27
參考:
IM :
即時通訊系統(IM,Instant Messenger)。
Android第三方即時聊天SDK的有:網易雲信、環信和融雲等。
這裡以環信來做即時通訊demo達到兩個效果:
1、使用者登入,
2、使用者間即時通訊
環信的功能類似伺服器。A和B使用者的互動都要經過環信這個伺服器。
環信框架整合
1、下載環信sdk開發包
下載後sdk目錄如下:
2、註冊成為環信開發者
3、在環信平臺上建立應用程式,獲取AppKey
4、在環信平臺上註冊使用者
5、建立Android studio專案,匯入SDK開發包中的庫檔案
5.1 將sdk包lib中的jar檔案放到as專案中的libs中,並add library(可看原始碼即可)
5.2 as專案src/main中new 一個directory,命名為jniLibs,然後將sdk包lib中的其他三個資料夾放到jniLibs中。
6、新增許可權
7、配置AppKey
8、宣告SDK所需的Service和BroadcastReceiver

9、SDK初始化
package com.example.administrator.myapplication;
import android.app.Application;
import com.hyphenate.chat.EMClient;
import com.hyphenate.chat.EMOptions;
/**
* Created by Administrator on 2017/6/9.
*/
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
//配置環信sdk
EMOptions emOptions = new EMOptions();
emOptions.setAutoLogin(false);
//初始化環信sdk
EMClient.getInstance().init(this, emOptions);
}
}
10、登入
介面:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
tools:context="com.example.administrator.myapplication.MainActivity">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@mipmap/ic_launcher" />
<EditText
android:id="@+id/et_name_login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:gravity="center"
android:hint="請輸入使用者名稱" />
<EditText
android:id="@+id/et_pw_login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:gravity="center"
android:hint="請輸入密碼"
android:inputType="textPassword" />
<Button
android:id="@+id/btn_login_login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:paddingLeft="40dp"
android:paddingRight="40dp"
android:text="登入" />
</LinearLayout>
程式碼:
package com.example.administrator.myapplication;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import com.hyphenate.EMCallBack;
import com.hyphenate.chat.EMClient;
import butterknife.BindView;
import butterknife.ButterKnife;
public class MainActivity extends AppCompatActivity {
@BindView(R.id.et_name_login)
EditText etNameLogin;
@BindView(R.id.et_pw_login)
EditText etPwLogin;
@BindView(R.id.btn_login_login)
Button btnLoginLogin;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
btnLoginLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//執行登入功能
EMClient.getInstance().login(etNameLogin.getText().toString(),//登入名稱
etPwLogin.getText().toString(),//登入密碼
new EMCallBack() {//子執行緒執行,不能更新UI
@Override
public void onSuccess() {
//登入成功
startActivity(new Intent(MainActivity.this, ChatActivity.class));
finish();
}
@Override
public void onError(int i, String s) {
//登入失敗
}
@Override
public void onProgress(int i, String s) {
//進度更新
}
});
}
});
}
}
11、傳送訊息,監聽訊息的獲取
佈局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/tv"
android:text="0000"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/et_name_chat"
android:background="@color/colorAccent" />
<Button
android:id="@+id/btn_send"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="傳送" />
<EditText
android:id="@+id/et_name_chat"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/et_content_chat"
android:layout_toLeftOf="@+id/btn_send"
android:hint="請輸入要傳送的人" />
<EditText
android:id="@+id/et_content_chat"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/btn_send"
android:layout_toLeftOf="@+id/btn_send"
