當我使用startActivity（意向）加載設置爲Theme.Dialog我的應用程序爲主題的活動顯示Toast通知了Android ：新活動的標籤。有沒有辦法關閉它？我發現，如果我跑在新的活動不會彈出吐司消息的OnCreate進度對話框，但我不想進度對話框或吐司消息。吐司與活動標籤彈出，當我使用startActivity（意向）與對話的主題活動
我所說的活性與：
Intent queriesIntent = new Intent(getApplicationContext(), GetQueriesPopup.class);
startActivity(queriesIntent);
而且我與Theme.Dialog活動：
public class GetQueriesPopup extends ListActivity {
private static String server;
private static String suffix;
private static String project;
private static int qid;
private static String[] qidsArray;
private static String username;
private String[] queries;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final SharedPreferences app_preferences = PreferenceManager.getDefaultSharedPreferences(this);
server = app_preferences.getString("server", "none");
username = app_preferences.getString("username", "none");
project = app_preferences.getString("project", "none");
try
{
GetMap.showProgressDialog(true);
getRequest();
}
catch(Exception ex)
{

alertDialog.setTitle("GTWeb");
alertDialog.setMessage("Couldn't get a list of available queries, please check internet connection.");
alertDialog.setButton("OK", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Intent intent = null;
intent = new Intent(getApplicationContext(), GTWeb.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
});
alertDialog.show();
}
}

{
if (server.endsWith("/"))
{
suffix = "queries.aspx?usr=" + username + "&prj=" + project;
}
else
{

}
String url = server + suffix;
new HttpConnection().execute(url);
