android-tabhost

问题 How do I switch between tabs from within one of the activities that is located inside the tab host? I need to complete the project by tomorrow. My project involves showing 3 tabs with varying content. So please help anyone. 回答1: If you added the tabs as activities you can use this code inside a tab child activity TabActivity main = (TabActivity) getParent(); // get the main 'TabActivity' from a Child (tab) TabHost tabHost = main.getTabHost(); // get a handle to the TabHost tabHost

问题 I've generated a custom action bar here and everything works except for tabs. Tab indicator and tab background color stays the same no matter what. tab_indicator_ab_recorder.xml file: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- Non focused states --> <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_recorder" /> <item android:state_focused="false" android:state_selected=

问题 I have an Activity which has a Scrollview as the top level element. Inside there are some other Views and at some point there is a TabHost. You might get a better impression by looking at the screenshot. The TabHost has three tabs, each with another Activity that are launched by an Intent. Everything is working fine except one thing. Whenever I click on a Tab, the Scrollview automatically scrolls down as you can see over here. The TabHost is out of the screen afterwards. I simply don't want

问题 I would need to know how to handle the intent between tabs. For example, I have a tab activity with two tabs. First on content is a text view. another one is a map view. When i click that text view it redirects to the tab2. it can be easily achieved by setCurrentTab(1) or setCurrentTabByTag("tab2") methods. But i want to pass lat and long values to that Map Activity to drop pin. What is the better way to use intents or getter/setter in java? What do you prefer? if your answer is "Intents".

问题 I'm struggling with the problem that the .onWindowFocusChanged() doesn't get called in my custom Activity class. My setup: Two tabs (containing Activity_1 and Activity_2) in a TabHost, where the 2nd tab is selected by default: tabHost.setCurrentTab(currentTabIndex); In both Activities, I added the onWindowFocusChanged() override (because I need to preform calculations after the layout is done drawing): @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged

问题 Is there a way we can add setOnLongClickListener in Tabs?? Or is there any other way where i can call one activity when clicked on a tab and a different activity when long clicked on the same tab?? public class HelloTabWidget extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); TabHost tabHost = getTabHost(); TabHost

问题 I use a TabHost. The below code to call AActivity. intent = new Intent().setClass(this, AActivity.class); spec = tabHost.newTabSpec("A").setIndicator("A", res.getDrawable(R.drawable.icon)).setContent(intent); tabHost.addTab(spec); And it is in the tab. But in AActivity I call BActivity. The BActivity will open new page, but not in the tab. How to let it on the tab frame? AActivity use below code to call BActivity: it = new Intent(this, BActivity.class); startActivity(it); 回答1: If you want to

问题 I just encountered a problem in layout design with tabhost . i need exactly the same design so that on selecting a tab it will come in cented of the screen. with design like in these pictures. 回答1: Currently ViewPagerIndicator is the best resource for getting this done without too much code. As for the same design you're going to have to do a little work yourself to get that done. If you look through the samples on the projects github you'll see some examples of how the ViewPagerIndicator can
