Question

我使用Twitter4j api将Twitter构建到我的Android应用程序中以查看一个用户的推文。然而，它只提出了7条推文。我想要至少20 ...这很奇怪，因为我把数量设定为50 ..任何人都可以帮忙吗？感谢

public class Twitter extends Activity{
    LinearLayout tweets;
    Context cont;
List<Status> statuses;
    String separatorText = "test";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.twitter);
        cont = this;






        statuses = new ArrayList<Status>();



        tweets = (LinearLayout) findViewById(R.id.twitter_main_content);
        if(Network.CheckInternet(this)){
            new tweets().execute();
        } else {

            Toast toast = Toast.makeText(this, getResources().getString(R.string.nointernet), Toast.LENGTH_SHORT);
            toast.show();
        }
    }

    public void QueryTweets(){
        ScrollView sView = new ScrollView(cont);
        sView.setVerticalScrollBarEnabled(false);

                if(!dateCompare.equals(separatorText)){
                    separatorText = dateCompare;

你应该使用Paging，看一眼： Working with timelines, pages 要么 Twitter4j Code-Examples - Paging 要么 Twitter4j Paging javadoc

编辑在你的情况下我会用这个： From Twitter4j doc

以下是我如何设法获得100条推文（我正在向SQLite DB发送推文，但在您的情况下分页会相同）

   void fetch_timeline(){



    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();

    List<Status> statuses;
    int count= 100;
    try {

        statuses = Constants.TwConst.getHomeTimeline(new Paging().count(count)); // HERE'S WHAT WILL PROBABLY HELP YOU

        for(Status status: statuses){
            // HERE I PARSE TWEETS AND WRITE THEM TO DATABASE
        }
    } catch (TwitterException e) {
        e.printStackTrace();

    }
}

Twitter4j - 只提供用户的几条推文--Android
