我这样做:

toolbar = (Toolbar) findViewById(com.sports.unity.R.id.tool_bar);
setSupportActionBar(toolbar);
setTitle("hello");

我想在标题"hello"中为文本设置自定义字体.怎么做？

我在android中使用Facebook sdk 4.4.0,我希望使用图形请求获取用户的当前个人资料图片.怎么做？

我见过人们用

用于提取个人资料图片的API,但我无法想象如何从中提取个人资料图片.

即时通讯使用服务来保持我的xmpp连接始终处于活动状态是代码:

public class XMPPService extends Service {


@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    new ConnectionStatus().execute();
    return START_STICKY;
}

@Override
public void onCreate() {
    Log.i("service", "created");

}
public class ConnectionStatus extends AsyncTask{

    @Override
    protected Object doInBackground(Object[] params) {
        XMPPClient.getConnection().addConnectionListener(
                new AbstractConnectionListener() {
                    public void connectionClosed() {
                        Log.i("connection", "closed");

                    }

                    public void connectionClosedOnError(Exception e) {
                        Log.i("connection", "closed on error");

                    }

                    public void reconnectionFailed(Exception e) {
                        Log.i("reconnection", "failed");

                    }

                    public void reconnectionSuccessful() {
                        if (XMPPClient.getConnection().isAuthenticated()) {
                            Log.i("isauthenticauted : ", …
