Android :: How Can We Change View Within Tabs?

Dec 10, 2009

I want to provide a clickthrough on the list in a tab which opens another view. I need to open the new view within the same tab. I then need to provide a back button on the changed layout to change the view to original view.I have tried this. I am trying to access the tabSpec from main activity class [MainTabView] and set the intent as follows. Java: MainTabView.tabSpec1.setContent(new Intent(this, AView.class)); MainTabView.mTabHost.setCurrentTab(0); MainTabView.mTabHost.invalidate(); But this does not change the view immediately but changes it when I go to another tab and come to the starting tab. How can I make it to refresh it as soon as the content has been changed to another intent?

When I run the examples, everything shows fine, so I went as far as to just about copy most of the layout from the examples(a mix of and, but for some reason it still wont run, any ideas?

Here is my code(List1.class is a copy from the examples for testing purposes). It all compiles fine, just gets a force close the second it starts:

Android :: Using The Same View On Both Tabs

Oct 3, 2010

I'm working on an Android application with an activity that uses a tab layout. There are two tabs which switch between the content being shown in a ListView below.

This means that the two tab specifications point to the same ListView for content,


This somewhat works - if I switch to tab #2 and back to #1, I can see the ListView and my database code gets the right data based on the selected tab. However, when the activity launches, the ListView can't be seen before tabs are changed. This is obviously a problem.

Android :: Content In Tab - Change It With Out Losing Parent Tabs

Nov 20, 2010

I have been asked to create an app to buy sell and advertise a product. I have chosen dvd's to keep it simple. Using the tutorials on the android developer site I have created 3 tabs one for PG films one for 15 and one for 18. Now in these tabs I want to have a button that then changes the content of the tab but keeps the tabs.

I have tried so many things and the only thing I have been able to do is start a new activity but that gets rid of the tabs :( and I have tried many other things been up all night trying to work this out. If someone could just point me in the right direction to how to go about this would be great. Is it even possible?

Android :: Scrollable Tabs - Dolphin Browser When Using Multiple Tabs

Jun 19, 2010

I'm currently working on my first android application. I am using a tabbed layout for my application. I followed the tutorial for this on the dev guide and ran into a problem. The tutorial only used three tabs, but I have a need for more. As such, the tabs resize and bunch up. I was hoping someone could tell me how I can make them scroll, like in dolphin browser when using multiple tabs.

Android :: TABS In 2.0 Vs 1.5 - Rounded Corners TABS

Feb 27, 2010

I simply use the tabwidget :


Why are my tabs so uggly in 2.0 (no more rounded corners as in 1.5/1.6) ?

ugly tabs here


This was better

What should I do now to show "rounded corners" TABS to Nexus One (for exemple) users ;-) ?

Is it because of the following manifest lines :


I have to keep android:anyDensity="true" otherwise I've got a problem with re-sizing of the menus described here

As a separate question, my users can change the Locale within my app itself, I then "redraw" the menus using onPrepareOptionsMenu (Menu menu) to refresh the strings within the menu with the new language choosen by the user. Is there an equivalent for TABS (I have local strings within the Title of the TABS) or do I have to delete all the tabs and re-create them from scratch ?

Android :: Tabs - MapView - Activities Within Tabs

Oct 19, 2009

We're in the process of writing an app that has 4 tabs: Map, People, Places, Events. The People, Places, and Events in the App show up as Icons on the map. By default the People, Places, and Events tabs each show a listview, custom rendered, displaying all the People, Places, and Events respectively.

Now, right now each of the tabs has as its content an Intent set to launch the corresponding activity. For instance, there is a MapTabActivity that extends MapActivity, a ShowPeopleListActivity that shows the people, and so on and so forth.

I see a lot of StackOverflow questions/answers saying that due to various limitations in the way the TabHost is setup, it's best NOT to use activities as the content of tabs. For instance, it's impossible to launch a new activity and have it take the place of the existing activity within a tab, whereas it's possible to switch out a View with a different view.

Now, I'm at a crossroads. We've (for better or worse) devoted a fair amount of time trying to get this app to work the way it's currently structured, with the Activities as the content of the tabs. When an icon corresponding to a Person, Place, or Event is clicked, it fires off a VIEW Intent on a URI corresponding to that object; this is picked up by an Activity that then shows the object. The same mechanism is at work both in the Map and in the individual lists. We really like the loose coupling this provides us; we just give a VIEW command and the URI to the person/place/event and it automatically brings us to the right activity. Granted, the activity that's launched covers up the tab view rather than appearing inside of that, but we were willing to live with this.

Here's an issue though: from the Show activity, we want to be able to go back to the map, centered at that person, place, or event. We can launch a new activity to show the map again, but now we have the map activity as the content of the tab, plus the show activity, plus the new map activity in the activity stack; given how resource intensive the map activity is, I'm guessing this is not the ideal way to go.

I guess my question is, is there a GOOD tutorial somewhere showing exactly how to do complex tasks with a TabHost? I've seen HelloTabWidget; I'm looking for something much more sophisticated than this. I'm worried that if we switch to the View based way of doing things, we'll have to do a LOT of housekeeping to intercept all the back events, try to switch out the views, etc., etc., as well as strongly coupling our program in a way we don't want.

Android :: View On Press Onpress - Change Background Color On Press - How Do Show That The View Is Being Pressed

Jan 5, 2010

I have, for the time being, a custom view with a 9-patch image as a border.

That custom view is placed three times in a LinearLayout, so it looks like this:

| CustomView |
| CustomView |
| CustomView |

I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.

So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.

So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.

Android :: Change View Of Tab

Nov 19, 2010

I've got a TabHost with three tabs; each holding one activity.I'd like to change the view of one tab to another view - how can I do that programatically? I don't like to use ActivityGroups, as I've experienced several problems with ActivityGroups.It would be perfect if I could add a View on top of the current one, so the back button is working, too (or at least I could fetch the back button and remove the topmost view).

Android :: View Size After Orientation Change

Jun 17, 2009

Is the view aware of the orientation change in order to return updated size after a change in orientation? I'm handling the orientation myself (android:configChanges="orientation|keyboardHidden"). Does it means that I have to take into account the orientation state when querying for view.getHeight()? The view returns the same value as before the orientation change. It this the normal behavior or I should "notify" somehow the view to "refresh" its size.

I'm trying to make a timeout gauge bar animation effect:The width of a lengthy colorful bitmap image is decreasing, but not the image looks not changing and the visible area shrinks.I couldn't find the sole ImageView clipping or masking support in android.then changing the shrink_box's width will clip the portion of the still_image.But I failed to change the width of the view smoothly.I tried to change the LayoutParam.width in applyTransformation() but got an Exception, it seems not allowed. How can I make an Animation that changes the width of the view. OR is there a proper method to achieve the above effect?

Android :: Change Text View At Run Time

Sep 16, 2010

i“m working with a lineal layout and I“m trying to change the text of a TextView but it doesn“t refresh. When I debug I“ve checked that the text have changed correctly.public class Position extends Activity {
Button botonempezar;
Button botonsalir;
TextView text;
public void onCreate(Bundle savedInstanceState) {
botonsalir = (Button) findViewById(;
botonempezar = (Button) findViewById(;
text = (TextView) findViewById(;
botonsalir.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
} botonempezar.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
private void searchPosition(){
boolean condition = true;
}while(condition == true);
private void determinatePosition(){
this.text.setText("New text");
Toast.makeText(getBaseContext(), "New text", Toast.LENGTH_SHORT);// this doesnt work neither.
Here I post the code of the xml file. Its really silly but it could be the problem:
<?xml version="1.0" encoding="utf-8"?>
android:text="PosiciĆ³n desconocida"
<Button android:layout_height="wrap_content"
android:id="@+id/Empezar" android:text="Empezar"
android:text="Finalizar programa"
android:gravity="center" android:layout_width="fill_parent">
I have edited the post because I omitted part of the code to make it simpler but I think I may suppressed the problem too. It runs in a endless loop, could be this the mistake?

Android :: Way To Have View Use Different Layout When Orientation Change Occurs

Oct 2, 2009

is there a way to have a view use a different layout when an orientation change occurs. suppose i want the view to look one way in portrait and another way in landscape. all the same data, but arranged differently.I'm thinking one way to do this would be to have two different linear layouts with android:visibility="gone" and simply display the appropriate one (set android:visibility="visible") based on orientation -- i.e. do this from there a way to do this in xml? or something like this (i.e. in landscape, put the textview here, in portrait, put it here instead)?
