  • Custom layout in Android: scrollable graphic with selectable elements over top

    - by Martyn
    Hi, I'm fairly new to the Android platform and was wondering if I could get some advice for my current head scratcher: I'm making an app which in one view will need an image, which can be scrolled on one axis, with a load of selectable points over the top of it. Each point needs to be positionable on the x and y (unlikely to change once the app is running, but I'll need to fine tune the positions whilst I'm developing it). I'd like to be able to let the user select each point and have a graphic drawn on the point the user has selected or just draw a graphic on one/more points without user intervention. I though for the selectable points I could extend the checkbox with a custom image for the selected state - does that sounds right, or is there a better way of doing this? Is there any thing I can read up on doing this, I can't seem to find anything on the net about replacing the default images? I was going to use the absolute layout, but see that it's been depreciated and I can't find anything to replace it. Can anyone give me some code or advice on where to read up on what I need to do? Thank you in advance

  • How can I compress jpeg images in Java without losing any metadata in that image?

    - by guitarpoet
    I want compress jpeg files using Java. I do it like this: Read the image as BufferedImage Write the image to another file with compression rate. OK, that seems easy, but I find the ICC color profile and the EXIF information are gone in the new file and the DPI of the image is dropped from 240 to 72. It looks different from the origin image. I use a tool like preview in OS X. It can perfectly change the quality of the image without affecting other information. Can I done this in Java? At least keep the ICC color profile and let the image color look the same as the origin photo?

  • How to blit() in android?

    - by Lo'oris
    I'm used to handle graphics with old-school libraries (allegro, GD, pygame), where if I want to copy a part of a bitmap into another... I just use blit. I'm trying to figure out how to do that in android, and I got very confused. So... we have these Canvas that are write-only, and Bitmaps that are read-only? It seems too stupid to be real, there must be something I'm missing, but I really can't figure it out.

  • Android @Override usage

    - by BahaiResearch.com
    (Newbie to Java, old time C# guy.) I have noticed a lot of the use of @Override in Android example code. I thought that all Java methods were by default "Virutal"? What then does @Override do? Example: private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }

  • Help me choose between XML or SQL Lite on android

    - by Ngetha
    I have an android app that periodically, say once a week downloads content from a server in XML. The content is used by the app, different Acitivities use different parts of the content. My question is a design one, should I save the data in SQlite or just keep it as an XML file, which one would be faster to read? The app can only use one content piece at a time, which means subsequent XML content downloads replace the old one.

  • The Relationship Between Activities and View Objects - Android

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

  • Android Speed based on accelerometer values

    - by fraguas
    Hi. I need to obtain the velocity of an android device, based on the accelerometer values. I made a code that allows me to get the accelerometer values, and then I calculate the velocity, using the formula: v = v0 + at. (vector calculation) My problem is that my velocity only increases and never decreases. I think the problem is that the device never gets an negative acceleration. Can you help me with this?

    Is there a way to change the sync settings of a Gmail account programmatically with an Android app? For instance, I'd like to enable/disable syncing of a Gmail account from my app, without the user having to do anything.

  • editText not centering

    - by Will Nasby
    I have a large editText that no matter what I try, won't center. I have tried putting it in a horizontal and vertical linear layout and then setting that gravity to center because setting the imageText's gravity to center, it still hugs the left of my activity. <EditText android:id="@+id/editText1" android:layout_width="250dp" android:layout_height="wrap_content" android:ems="10" android:gravity="center" android:lines="8" android:maxLines="8" android:minLines="8" > </EditText> And here is what it is doing:
