tabhost的行爲默認情況下會自動選擇第一個選項卡並顯示它的內容。問題是,我想設置它的默認頁面。 (這意味着,默認情況下,tabhost未被選中,並顯示一些主頁內容(不是tabhost的內容))。如何實現這樣的功能?謝謝。如何在android中設置標籤主機的默認頁面?
主要活動
public class LandingPage extends FragmentActivity {
public FragmentTabHost tabHost;
public Resources res;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.landing_page);
res = getResources();
tabHost = (FragmentTabHost) findViewById(R.id.tabhost);
tabHost.setup(this, getSupportFragmentManager(), R.id.tabcontent);
tabHost.addTab(tabHost.newTabSpec("About").setIndicator("",res.getDrawable(R.drawable.btn_about)),About.class, null);
tabHost.addTab(tabHost.newTabSpec("Selfie").setIndicator("",res.getDrawable(R.drawable.btn_selfie)),About.class, null);
tabHost.addTab(tabHost.newTabSpec("Gallery").setIndicator("",res.getDrawable(R.drawable.btn_gallery)),About.class, null);
tabHost.addTab(tabHost.newTabSpec("LeaderBoard").setIndicator("",res.getDrawable(R.drawable.btn_board)),About.class, null);
tabHost.addTab(tabHost.newTabSpec("Events").setIndicator("",res.getDrawable(R.drawable.btn_events)),Events.class, null);
}
}
