カスタムタブがあり、非常に1分後にWebサービスにアクセスし、Webからデータをフェッチするサービスをバックグラウンドで実行しています。次に、データを受信したときに最初のタブ画像が変更されるようにします。助けてください。よろしくお願いします。
私のコード
public class MainTabActivity extends TabActivity {
public static TabHost mTabHost;
public static TextView offLineText;
private void setupTabHost() {
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.tab_test);
