android-tabhost

问题 So android goes out of its way to build this nice UI guide for everyone to use. But I don't see anywhere where it shows code examples of how to build these elements. The UI guidelines for tabs can be found here. http://developer.android.com/design/building-blocks/tabs.html. Does anyone know how to create tabs likes the this one? Any help would be appreciated, thanks. SOLUTION POSTED Ok, so here is what I ended up doing after probably wasting about 10 hours trying to make some good looking

问题 Few days ago I implemented TabHostFramgent in a Fragment with a NavigationDrawer , and I faced with a problem that is the following error : java.lang.IllegalStateException: No tab known for tag null The thing is that all works perfectly since my first item list of my NavigationDrawer is my TabHostFragment , so it works perfect, but the problem is when I go in example to the second item and then I want to go back to the first item, every time that I try so it crashes. I was searching

问题 I have looked at posts on Stack Overflow and at tutorials on other websites, and I cannot understand how to use TabHost . Can someone please explain it to me and maybe send me a link to a tutorial? 回答1: In ManiActivity extends TabActivity public class MainActivity extends TabActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.activity_main); TabHost mTabHost = getTabHost(); mTabHost.addTab(mTabHost.newTabSpec(

问题 I have a question about Honeycomb's backward compatibility. I have an app that supports 2.1 or higher and seems to mostly work on Honeycomb except when they start a TabActivity. In particular, when I add tabs to the TabHost, I get the following exception android.content.res.Resources$NotFoundException: Resource ID #0x0 When looking at the code that throws this exception, I see that it's the tab spec that has a label and an icon. Inside the code, in the LabelAndIconIndicatorStrategy tries to

问题 I have a TabHost control (not in actionbar), and I want to make the tabs to change when the user swipes the context on each tab (something like whatsapp emoji tabs). How can I do this? EDIT The feel is also important. I want that the contexts should have scroll animations (No matter if the user swipe or if the tab is clicked). 回答1: Go through this link http://thepseudocoder.wordpress.com/2011/10/13/android-tabs-viewpager-swipe-able-tabs-ftw/ You can use a gesture detector.

问题 I tried to use a background (480x320) for my tab content. Using a xml as drawable, I should be able to scale the image. This works fine outside the tabhost/tabactivity. If I try to use it inside the tabcontent, the scaleType doesn't work. He ignores every scaleType I tried. tabcontent: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="

问题 I want to create custom buttons to use in a TabHost. I haven been trying to just use the same image resource (png), but have the colorfilter change depending on the state. So I made this bit to serve as the layout for the custom button: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/tab_icon" android:layout_centerInParent="true"

问题 Following situation: I have TabActivity with e.g. three tabs, TabA, TabB, TabC. There are a button in activity (Act_C_1) of TabC. So if the user clicks on that button, another activity (Act_C_2) should occur in TabC. I thank you in advance for any suggestions / or ideas. Mur UPD: Here is my code TabActivity with three Activities: public class TabScreen extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tab_menu);

问题 Greetings, I am trying to get the Click - event when clicking on the currently selected tab of my TabActivity. The onTabChangedHandler is only called whenever the tab is changed, not if the currently active Tab is clicked. The debugger tells me i have the onClickListener Registered for the TabWidget within my TabHost. Am i registering for the wrong View? Also, I am unable to create a Context Menu for the Tabs, only for its content, is this problem related? public class TestDroidViewTab

问题 I'm going to create an application which is designed to use Tabhost , but as I know it's been deprecated. So my question is should I use Tabhost anyway or how can I replace it..by using buttons instead of them declared in every xml or any other suggestions? 回答1: "Deprecated" in Android means "we think there is a better solution that you should investigate". Rarely does "deprecated" mean "it is unusable". TabHost , AFAIK, works fine on Android 4.0. That being said, I would recommend
