I'm building an Android App where users need to be able to edit their own content, including minimal layout. I just want to store the formatted source in the database and pull it out and display it the way I would with something like TinyMCE in a web app. Any ideas how users can enter and format their own content in an Android GUI?

Based on the limitations of RemoteViews, it looks to me that the appropriate way to get it actually drawn on the screen is to use an ImageView in the actual layout, then when it is updating, create a ShapeDrawable or two and draw them onto a newly created Bitmap. Then, set that Bitmap as the source of the ImageView. There is Something about that process that I'm just not grokking, though. The following is the code I tried to use to update the widget. I get nothing drawn on the screen at all. The ImageView has a placeholder image just set by its src property. When I don't run the code to update it to my drawing, the placeholder image stays in place. So, I know this code is doing something, just obviously not the right thing.
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
Bitmap bitmap = Bitmap.createBitmap(100, 100, Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
ShapeDrawable drawable = new ShapeDrawable(new ArcShape(0, 360));
drawable.getPaint().setColor(0xffff0000);
drawable.getPaint().setStrokeWidth(5.0f);
drawable.setIntrinsicWidth(100);
drawable.setIntrinsicHeight(100);
drawable.draw(canvas);
views.setImageViewBitmap(R.id.ImageView01, bitmap);
appWidgetManager.updateAppWidget(appWidgetId, views);
I knew it couldn't be that easy. So, am I even heading in the right direction? Update Ok, maybe that was too much information. The question I'm really trying to ask is this: If I want to draw shapes on a widget, should I use an ImageView and create a bitmap from my ShapeDrawable or is there more appropriate way to draw into a widget where it is constrained by RemoteViews?

View 3 Replies View RelatedThis may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?
View 2 Replies View RelatedI have a EditText in android in which i want the user to enter the text and checks for the condition "BYE"
Code sample..
How can i make user to enter the text?The UI should wait for the text to be entered(something like we have InputStreamReader in java applications).
I am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.

View 2 Replies View RelatedIs there an explanation of the ADT layout editor UI some place? I can't find anything on the Android web site about it. When I look at a layout in the design view, there are a number of fields at the top with labels like MCC, MNC, Lang, etc. I've noticed that I can change the contents of these fields, such as orientation, and it has an effect on the view. But a yellow warning triangle appears next to the field I've changed and the next time I open this view I see the unmodified field. For example, if I change to landscape orientation the view goes back to default next time. Is there documentation some place on what these fields mean and how they are supposed to be used?

I'm developing an image editor application for Android. I have a big problem: I haven't a mobile with Android. I found a person that helps me to test the application and I found many problems. The application works in the emulator perfectly but in the mobile the application constantly mistakenly ends. I want to print a log similar that the show in ddms in a file on the SDCard. I did it with a FileWriter but it isn't the same that I can see in ddms.
Is it possible to show the same output as ddms in a file?
If not possible I would like to get as much information as possible. The person who has the mobile don't have knowledge of programming and I have not got close.

Whenever I have them present in a layout, the graphical representation of the layout disappears, and "NullPointerException: null" replaces it.

View 2 Replies View RelatedI am devoloping an application of image editor. I always do it by using the resources in the drawable carpet. Now I changed it to use the resources in the SD card. I don't change the code of the image access but the program always produce an error if I intent to set the value of a pixel. The program works correctly if I try to read the pixel but if I try to modify it fails. I think this is a permissions error but I added the following: <uses-permission android:name="com.android.editorImagenes.permission.WRITE_EXTERNAL_STORAGE"></ uses-permission> <uses-permission android:name="com.android.editorImagenes.permission.WRITE_OWNER_DATA"></ uses-permission> And everything remains exactly the same. I'm desperate. A thing happens is that if I try to do the scaling or rotating the image using a matrix postrotate, etc, the program works correctly and as of this moment I can use the SetPixel without causing error.

I'm new to Android & Eclipse. I've downloaded Eclipse and the Android ADT and created an ultra-simple "Hello World" app (has only auto-generated .java and .xml files). Eclipse CRASHES (closes after a very brief pause) when I do the following: In Package Explorer, select AppName/res/layout/main.xml Press, or double-click, or 'Open With' then 'Android Layout Editor' (The app runs OK in the Android emulator) My configuration is:
Android Development Tools 0.9.5.v200911191123-20404 com.android.ide.eclipse.adt.feature.group
Eclipse IDE for Java Developers 1.2.2.20100216-1730 epp.package.java
Windows XP
Can someone tell me what I'm doing wrong or what's wrong with my configuration? Any suggestions on what to check? For any non-trivial app development I need to be able to use the Layout Editor. More ... I can select main.xml and Right-Click and 'Open With' any of: XML Editor, XML Schema Editor, Text Editor -- with no problem. The problem is limited to Android Layout Editor.
Has anyone figured out how to scroll the contents of the Layout Editor when those contents overflow one "screen"? I'm talking about at design-time while using the ADT Layout Editor, not scrolling at run-time on a physical device (that works fine).
