我创建了一个带有 3 个选项卡的应用程序。该应用程序运行良好,但我希望在应用程序打开时选择并加载第二个选项卡。我该如何设置?
这是我的代码:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost = getTabHost();
// Tab for Home
TabSpec homespec = tabHost.newTabSpec("Home");
// setting Title and Icon for the Tab
homespec.setIndicator("Home",getResources().getDrawable(R.drawable.icons_home_tab));
Intent photosIntent = new Intent(this, HomeActivity.class);
homespec.setContent(photosIntent);
// Tab for Child
TabSpec childspec = tabHost.newTabSpec("Child");
childspec.setIndicator("Child",getResources().getDrawable(R.drawable.icons_child_tab));
Intent homeIntent = new Intent(this, ChildActivity.class);
childspec.setContent(homeIntent);
// Tab for Account
TabSpec accspec = tabHost.newTabSpec("Account");
accspec.setIndicator("Account",getResources().getDrawable(R.drawable.icons_account_tab));
Intent accIntent = new Intent(this, AccountActivity.class);
accspec.setContent(accIntent);
// Adding all TabSpec to TabHost
tabHost.addTab(homespec); // Adding home tab
tabHost.addTab(childspec); // Adding child tab
tabHost.addTab(accspec); //Adding account tab
}
