Android :: Create Non-default Style Widget Programmatically
Jul 21, 2009
In ApiDemo, there is a progressBar demo. It creates a horizontal progress bar with a xml.
<ProgressBar android:id="@+id/progress_horizontal" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" />
But how to create one programmatically? If just new ProgressBar(fContext), it is Default ProgressBar style.

I see there is a TextAppearanceSpan available but no examples on usage. I just want to make the text bold and leave everything else unchanged - is there perhaps a simpler way to do this programmatically?

I create my own widget with its own drawable for background.
So in my styles.xml file, I have this: <resources> <style name="MyWidget"> <item name="android:background">@drawable/btn_mywidget_bg</item> </style> </resources>
In my main.xml, if i specified my 'style' attribute, my background drawable was displayed correctly. <test.MyWidget android:id="@+id/mywidget" style="@style/MyWidget" />
but if I just do this: <test.MyWidget android:id="@+id/mywidget" /> , the background drawable is not display correctly.
Can you please tell me how can I specify the default style of my widget so that I don't need to add style="@style/MyWidget" everytime I use my widget?

What would be the best way to create a theme programatically and set it as the theme of an activity. Not using onCreate, but rather really embed it in the package in a way that if a define a background it will appear even after onCreate finishes. My first guess is to use the PackageManager but I'm not seeing a way through...

I'm looking at best way of creating Accordion-style widget such as on this page http://is.gd/1GNI3 What would be the best way of achieving same effect using standard Android toolkit or do I need to build custom widget? If so - which one would you recommend extending if any?

This question is about setting the "style" attribute programmatically, but it needs a bit of background first. I wish to create a custom component which will looks like a EditText box but not actually allow direct input. (When focused or touched it will pop up a dialog to allow data to be entered).

Other questions say that the style cannot be set programmatically, but a View can be initialised with a style such as when it is loaded from XML.How can I initialise a View with a particular style programmaticly (not in XML)? I tried using View(Context context, AttributeSet attrs, int defStyle), but I don't know what to parse in for the second argument. Passing in null results in the View not being displayed

I am trying to make a sniper style game where the user looks through a scope to see a large image that he can navigate. The user can only see part of the image at a time. The image is supposed to be much larger than the screen size that way he has to actually navigate and look for the enemy. How do I use an image that is larger than the screen that the user can navigate?It is kind of like when you are zoomed in to an image and you can pan the image and move it around to see different parts.

Is there any documentation that explains how to create buttons in the style of the new market app on the top of the screen? I'm not sure if they're actually buttons or tabs, but I want to recreate that button style in my app (flat gradient buttons that dynamically fill the entire height/width depending on orientation).

I want to create an XML file to Store my Application Settings into. ( I can't use SharedPrefs because i want that Settings file later to be accessed by Some other Code.)
I can easily create an XML with java's code and store it in File too. but in Android I can create xml with the same java code but can't save it into the file coz they have removed the package javax.xml.transform from SDK.
I am Attaching the Java code here...

I'm trying to cook a rom and i want to set a style (sliding tab) as a default for lockscreen and incall lockscreen. I think i have to edit or add some line in lockscreen_style_settings.xml that is stored in CMParts.apk
esxml
Or maybe i have to edit settings.xml stored in Settings.apk
esxml?
I think I have to edit CMParts.apk, esxmllockscreen_style_settings.xml because when i my backup's datadatacom.cyanogenmod.cmpartsshared_prefs there is a file named com.cyanogenmod.cmparts_preferences.xml that contain's some line's about lockscreen.
Here is the com.cyanogenmod.cmparts_preferences.xml line's:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<boolean name="pref_trackball_wake" value="true" />
<string name="pref_install_location">0</string>
[Code] .....
I decompiled the CMParts.apk but i dont know which line's should be edited or what to add!

I want to launch an Activity with a webView as its content from current Activity. This new activity needs to be transparent and webview should be in the center. I looked around the web but only solutions I found were using style xmls. I want to do it using pure code i.e. no xml declarations. if anybody has come across this then please shed some light.

I need some help with the following scenario, as I am so used to make all of my layouts with XML, but now I have a situation where that won't work.
I am working on the second version of my app that delivers news, in the comments section I used to use a listview to display user comments, but it doesn't work that great for comments that could be anywhere from 5 to 500+ characters long. So I want to create a whole bunch of TextViews in a scrollview and stack them below each other.
My best guess was this, although it is definitely wrong because it only shows one comment. I assume I have to use some kind of LayoutParams and so I've looked into it but am still not sure how exactly to use them.

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.
Here's what I got:
This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):
ArrayList<String> spinnerArray = new ArrayList<String>();
This is code ...
Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ).
It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it.

Gallery in Android is only horizontal scrolling support. And we want make one with vertical scrolling support.
We got plans below. Can anyone give us some advice about which one is right?
1) Linearlayout ( We think it's bad)
2) ListView ( We think it's a good option and get a little worry about performance--too many pictures!)
3) subclass of AbsSpinner like Gallery and do something like Gallery source.
Which one is easy, time-saving and less performance or other problems.

Does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets?
What are the pros/cons of both approaches?
I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.

I have an xml layout that will display a grid made up of textviews within tablerows. The textview names are cell00, cell01, etc. At runtime, my program will determine which cell needs to be changed.
Is there a way get format a name so that it can be passed to the findViewById method at runtime? For example, if cell00 is needed, how can I generate the parm in this code?
TextView currcell = (TextView) findViewById(R.id.cell00)
Something like "cell"+00 doesn't compile because the findViewById method doesn't accept a String type. I don't want have every textview name in the grid hardcoded in the program - there must be a better way.

I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it. Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget):
public class ExampleAppWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout);
views.setOnClickPendingIntent(R.id.button, pendingIntent);................
