In my application i want to change button text for every 3 sec.
View 3 Replies View RelatedI have a textview in my XML layout file, but when I try to change its text value with code pragmatically (dynamically, depending on which button the user clicks) then the text of the textview doesn't change.
This is the code that I tried:
TextView userText = (TextView) findViewById(R.id.User);
userText.setText(bundle.getString("user"));
In debug mode, I can see that usertext has the changed text, but the change doesn't appear on my mobile window... I don't know why.
EDIT: SOLVED! it was a problem with my relative layout, text is out of the window!
I'm trying to make an app with localisation built in, but I want a way that I can create a web link within the text, the URL being defined elsewhere (for ease of maintenance).
So, I have my links in res/values/strings.xml code...
But this didn't work either.
So, I'd like to know if there's a way of dynamically adding multiple URLs to different sections of the same text which will link to web content?
I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:paddingBottom="5px">
<TextView
android:id="@+id/destination"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="22dp"
android:text="@string/test_destination"
android:paddingLeft="5px"/>
<TextView
android:id="@+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="@string/test_date"
android:paddingLeft="5px"/>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/info"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5px"

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.
Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.
LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);
Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.
It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus
EDIT:
The problem now is adding text dynamically to the TextViews. I try this:
TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");
only to discover that dest is null. Any ideas why and how to fix this?
EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?
I want to show an AlertDialog with one option that might change on every request. So for example at one time I want to show the option "add to contacts" while another time it should be "remove from contacts".
My code does work on the first time, however Android seems to cache the AlertDialog so that onCreateDialog is not executed next time. Therefore the option doesn't change anymore. Can I prevent this caching, or is there just another way of changing the option?

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.

Let's say, there are four apps in the system: app1, app2, app3, app4.
Be default, when the system is up, all apps will be shown in the home screen. Now if we provide a customized log in screen, user A log in, then for this user, he can only see (and use ) app1 and app2. Then A log out, user B log in, he can only see app3 and app4.
Does API provide such capability to load the app list dynamically?

You know how when you type something incorrectly it corrects it to the most likely word? Well, in a few cases I have saved words on accident, like I saved the word "tou" once by accident. So now every time I type that it stays at that and doesn't auto correct to "you." How can I go into my saved words or even predictive text menu and edit words?
