Question

我有列表是否有twitter状态，我想在列表视图中填充它

public class TwitterTimeline extends Activity {
    List<Status> statuses;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_twitter_timeline);
        setTitle("Timeline");
        ListView listview = (ListView) findViewById(R.id.listView);
        Bundle b = this.getIntent().getExtras();
        if (b != null) {
            MyStatuses myStatuses = (MyStatuses) b.getSerializable("statuses");
            statuses = myStatuses.statuses;
            for (Status st : statuses) {// this prints all the status on the  catlog
                Log.d("Abharthan : ", st.getUser().getScreenName()+ ":" + st.getText());

            }

            ArrayAdapter<MyStatuses> adapter = new ArrayAdapter<MyStatuses>(this,
                    android.R.layout.simple_list_item_1, statuses);// this line is giving error

            listview.setAdapter(adapter);
        }

    }

这里的MyStatus类是：

import java.io.Serializable;
import java.util.List;

import twitter4j.Status;

public class MyStatuses implements Serializable {
    List<Status> statuses;
}

包含列表视图的布局文件是android_twitter_timeline.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.example.android.HomeWork3.TwitterTimeline">

    <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/listView"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />

</RelativeLayout>
