Setting the background color programatically of an android TextView doesn't seem to work.
I'm I missing something!
CODE:.............
I also have this file (colors.xml) in my res/values folder
CODE:................
Also, setting the text color causes the TextView to disappear.

Just had an odd problem with a TextView. Setting the visibility doesn't seem to work but doing the same on say a ScrollView does. Is this normal?
View 3 Replies View RelatedI'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.
I have an XMl file like below which I will use to set background for Textview:
row.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
The above Xml I will set as background for TextView in main.xml as below:
main.xml
<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>
But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.
In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?
Can I modify android.R.layout.simple_list_item_1? For eg., I want to change the text color of the textview inside the listview dynamically. For this, I need to get to the textview and change its color.. How can I do that?

Here is my Java code:
CODE:............
This works when I use Color.RED or Color.GREEN, but when I use my own colors. The color doesn't show up.
In the string.xml file i use the following tag
<color name="mycolor1">#F5DC49</color>
if i use : textview1.setTextColor(Color.CYAN);
it works, But :textview1.setTextColor(R.color.mycolor1);
This is not working.how to use the color tag in android?
I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?
Actually, what I want is a textview which can show the progress of something, I know progressbar in android,however,so far as I know, it can not contain any text(am I right?), so, I want to change the background color of the textview to show progress,from left to right gradually.
Is there any other way to do this?

View 1 Replies View RelatedI'm setting background color based on a given state of an object in each row in a list. That part is working just fine but when I set the background color on the outermost layout the row no longer highlights when selected. Probably a specific attribute I'm not setting/changing?

I tried setting <requestFocus/> in the layout and also tried calling requestFocus() in onCreate().
Sometimes it works and sometimes it doesn't. I have a profile for "in dock" to turn on GPS and bluetooth. Last night it didn't shut off and this am - DEAD battery. I've noticed sometimes in the dock it doesn't turn those features on either - but sometimes it does work?

I have written a very simple game with some simple animations, but I've noticed that when the phone checks email, or several other apps are running, the animations that update in my thread start behaving slowly or choppy. This is a problem as the game mechanic requires some careful timing of your screen touches based on the animations. So if it starts behaving erratically, the game doesn't really work well - and isn't much fun.
Is there a way to prevent this? Can my threads have a higher priority when they need to run?
SMS Popup works on 2.2 -- but the setting to increase the speed doesn't work. The color changes work (note, they don't work on the app's own test function, you have to send yourself a text), which I love, but I had to uninstall after realizing that the speed increase doesn't work.

I have so far found two bugs in Galaxo 1.6.3:
a) Speaker doesn't work in call (very weak). works well in ringtones etc.
b) Scrolling contacts by letter doesn't work.
Other than that this is a leap forward, especially with the overclock options!
Both bugs, as well as others, fixed in 1.6.3.1 update!

Can someone let me know how to do this?
I 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!
