Android 腾讯 云通信 用户头像更新

  最近项目中用到腾讯的即时通讯(云通信),做到C2C聊天这块。需要将聊天界面的己方和对方的默认头像替换掉。

具体操作如下：

1：对ChatAdapter.java类新增

private TIMUserProfile mMySelfProfile;

private TIMUserProfile mMyFriendProfile; 成员变量。通过get或者set方式注入。

对ChatAdapter.ViewHolder也新增

public TIMUserProfile mMySelfProfile;
public TIMUserProfile mMyFriendProfile; 成员变量.

通过ChatAdapter对ChatAdapter.ViewHolder的成员变量赋值；

2：对Message类的子类的showMessage(ChatAdapter.ViewHolder viewHolder, Context context)方法，

 已TextMessage为例，其他子类依次类推：

@Override
    public void showMessage(ChatAdapter.ViewHolder viewHolder, Context context) {
        clearView(viewHolder);
        if (checkRevoke(viewHolder)) return;
        boolean hasText = false;
        TextView tv = new TextView(MyApplication.getContext());
        tv.setTextSize(TypedValue.COMPLEX_UNIT_SP, 16);
        tv.setTextColor(MyApplication.getContext().getResources().getColor(isSelf() ? R.color.color_666666 : R.color.color_666666));
        List<TIMElem> elems = new ArrayList<>();
        for (int i = 0; i < message.getElementCount(); ++i){
            elems.add(message.getElement(i));
            if (message.getElement(i).getType() == TIMElemType.Text){
                hasText = true;
            }
        }
        SpannableStringBuilder stringBuilder = getString(elems, context);
        if (!hasText){
            stringBuilder.insert(0," ");
        }
        tv.setText(stringBuilder);
        getBubbleView(viewHolder).addView(tv);
        if(viewHolder.mMySelfProfile!=null){//这里采用的是facebook的图片加载，请大家自己按照自己的图片加载方式加载,这里不多叙述
        Utils.setImageByUrlOfPicasso(context.getApplicationContext(),viewHolder.mMySelfProfile.getFaceUrl(),viewHolder.rightAvatar,R.drawable.head_me);
        }
        if(viewHolder.mMyFriendProfile!=null){
        Utils.setImageByUrlOfPicasso(context.getApplicationContext(),viewHolder.mMyFriendProfile.getFaceUrl(),viewHolder.leftAvatar,R.drawable.head_other);
        }
        showStatus(viewHolder);
    }

3:ChatActivity类的改造：

通过TIMFriendshipManager.getInstance().getUsersProfile(users, cb);异步加载用户资料获取自己和用户的资料

/**
* 
* @Title: initTIMAction
* @Description: 获取聊天2个人资料
* @return void
* @throws
*/
private void initTIMAction() {
List<String> users = new ArrayList<String>();
users.add(identify);
final String user = (String) SPUtil.get(getApplicationContext(),
ContentValue2.TX_IDENTIFIER_FLAG, "");
if (!TextUtils.isEmpty(user)) {
users.add(user);
}
mISigModel.getUsersProfile(users,
new TIMValueCallBack<List<TIMUserProfile>>() {


@Override
public void onSuccess(List<TIMUserProfile> result) {
TIMUserProfile mySelf = null;
TIMUserProfile myFriend = null;
for(TIMUserProfile bea:result){
if(bea.getIdentifier().equals(user)){//自己
mySelf = bea;
}else{
myFriend= bea;
}
}
if( mySelf!=null && myFriend!=null){
startTX(mySelf, myFriend);
mySelf = null;
myFriend= null;
}
}


@Override
public void onError(int code, String desc) {
LogUtil.e("addFriend failed: code=" + code + " ,desc="
+ desc);
startTX(null, null);
}
});
}

private void startTX(TIMUserProfile mySelf, TIMUserProfile myFriend) {
input = (ChatInput) findViewById(R.id.input_panel);
input.setChatView(this);
adapter = new ChatAdapter(this, R.layout.item_message, messageList);
if (mySelf != null)
adapter.setmMySelfProfile(mySelf);
if (myFriend != null)
adapter.setmMyFriendProfile(myFriend);
listView.setAdapter(adapter);
registerForContextMenu(listView);
voiceSendingView = (VoiceSendingView) findViewById(R.id.voice_sending);
presenter.start();
}

至此。可以测试！
