1.首先你得找到一個依賴包,類似這樣的
依賴
2.Application
public class App extends Application {
protected static SharedPreferences sp = null;
protected static Context CONTEXT = null;
private String spName = "HuanXinDemo";
@Override
public void onCreate() {
super.onCreate();
if (CONTEXT == null) {
CONTEXT = getApplicationContext();
}
if (sp == null) {
sp = CONTEXT.getSharedPreferences(spName, MODE_PRIVATE);
}
initIMsdk();
}
public static SharedPreferences getSp() {
return sp;
}
/**
* 註冊IM
*/
private void initIMsdk() {
int pid = android.os.Process.myPid();
String processAppName = getAppName(pid);
// 如果APP啟用了遠端的service，此application:onCreate會被呼叫2次
// 為了防止環信SDK被初始化2次，加此判斷會保證SDK被初始化1次
// 預設的APP會在以包名為預設的process name下執行，如果查到的process name不是APP的process name就立即返回
if (processAppName == null ||!processAppName.equalsIgnoreCase(this.getPackageName())) {
// 則此application::onCreate 是被service 呼叫的，直接返回
return;
}
//EaseUI.getInstance().init(this,null);
EMOptions options = new EMOptions();
// 預設新增好友時，是不需要驗證的，改成需要驗證
options.setAcceptInvitationAlways(false);
EaseUI.getInstance().init(this, options);
EMClient.getInstance().setDebugMode(true);
}
/**
* 獲取appName
* @param pID
* @return
*/
private String getAppName(int pID) {
String processName = null;
ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List l = am.getRunningAppProcesses();
Iterator i = l.iterator();
PackageManager pm = this.getPackageManager();
while (i.hasNext()) {
ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo) (i.next());
try {
if (info.pid == pID) {
processName = info.processName;
return processName;
}
} catch (Exception e) {
// Log.d("Process", "Error>> :"+ e.toString());
}
}
return processName;
}
} 3.Util

getSupportFragmentManager().beginTransaction().add(R.id.container, chatFragment).commit();
}
}
private void initView() {
etId = (EditText) findViewById(R.id.etId);
}
private void submit() {
// validate
String etIdString = etId.getText().toString().trim();
if (TextUtils.isEmpty(etIdString)) {
Toast.makeText(this, "請輸入對方的id", Toast.LENGTH_SHORT).show();
return;
}
// TODO validate success, do something
}
}
6.Chat的xml
