Question

我有一个登录页面，如果用户点击登录页面，它将转到标签页。在标签页中，我调用了活动组页面。从活动组页面，它将调用主页活动页面。在家庭活动中，我将称之为webservices。当我点击登录时，它显示黑屏几分钟，需要时间。那时我必须为用户显示启动画面，直到加载标签栏。

我已实施，但以下代码无效。 style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme" parent="@android:style/Theme"> 
  <item name="android:windowBackground">@drawable/quest</item> 
</style> 
</resources>

的AndroidManifest.xml

 <activity android:name=".HelloTabWidget"
                   android:theme="@style/Theme">
      </activity>

有人可以提供示例代码吗？

    public class Splash extends Activity {
// stopping splash screen starting home activity.
private static final int STOPSPLASH = 0;
// time duration in millisecond for which your splash screen should visible
// to
// user. here i have taken 5 second
private static final long SPLASHTIME = 5000;

// handler for splash screen
private Handler splashHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {

        case STOPSPLASH:
            // Generating and Starting new intent on splash time out
            Intent intent = new Intent(getApplicationContext(),                                         
                             ac.class);
            startActivity(intent);
            break;
        }
        super.handleMessage(msg);
    }
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    // Generating message and sending it to splash handle
    Message msg = new Message();
    msg.what = STOPSPLASH;
    splashHandler.sendMessageDelayed(msg, SPLASHTIME);
}
 }

启动画面不适用于android中的标签栏的活动组
