android - ViewPager を既存の TabHost に追加する

Question

こんにちは、ビュー ページャーを既存のコードに追加したいと思います。追加する最良の方法は何ですか。ここに私の RssTabActivitty.java と RssChannelActivity.java があります。

RssTabActivity は、タブを初期化するための私の主なアクティビティです。RssChannelActivity は、RSS フィードをロードします。

ここに完全なソースコードがあり ます https://github.com/itcuties/Android-Multicategory-RSS-Reader

public class RssTabsActivity extends TabActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // First, set the content view
    setContentView(R.layout.activity_rss_tabs);

    // Then get the TabHost
    TabHost tabHost = getTabHost();

    /* *****************
     * Art tab
     */
    Intent artIntent = new Intent().setClass(this, RssChannelActivity.class);
    // Set Art category RSS URL
    artIntent.putExtra("rss-url", "http://feeds.reuters.com/news/artsculture?format=xml");

    // The name of the art tab taken from the String resources
    String artTabName = getResources().getString(R.string.tab_art);
    TabSpec artTabSpec = tabHost.newTabSpec(artTabName)
                                .setIndicator(artTabName, getResources().getDrawable(R.drawable.rss_tab_art))
                                .setContent(artIntent);
    // Add art tab to the TabHost
    tabHost.addTab(artTabSpec);

    /* *****************
     * Tech tab
     */
    Intent techIntent = new Intent().setClass(this, RssChannelActivity.class);
    // Set Tech category RSS URL
    techIntent.putExtra("rss-url", "http://feeds.reuters.com/reuters/technologyNews?format=xml");

    // Tech tab name taken from the string resources
    String techTabName = getResources().getString(R.string.tab_tech);
    TabSpec techTabSpec = tabHost.newTabSpec(techTabName)
                                 .setIndicator(techTabName, getResources().getDrawable(R.drawable.rss_tab_tech))
                                 .setContent(techIntent);
    // Add tech tab to the TabHost
    tabHost.addTab(techTabSpec);


    /* *****************
     * Sports tab
     */
    Intent sportsIntent = new Intent().setClass(this, RssChannelActivity.class);
    // Set Sports category RSS URL
    sportsIntent.putExtra("rss-url", "http://feeds.reuters.com/reuters/sportsNews?format=xml");

    // Sports tab name - string resources
    String sportsTabName = getResources().getString(R.string.tab_sports);
    TabSpec sportsTabSpec = tabHost.newTabSpec(sportsTabName)
                                   .setIndicator(sportsTabName, getResources().getDrawable(R.drawable.rss_tab_sports))
                                   .setContent(sportsIntent);
    // Add sports tab to the TabHost
    tabHost.addTab(sportsTabSpec);


    // Set current tab to Technology
    tabHost.setCurrentTab(1);
}
