  • Android menu view, gridview or something else?

    - by dfilkovi
    I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code. Can anyone post an xml example of this?

    I don't now if this title is very clear, but I would like to understand how this is possible : And how we can have 2 elements on the same row of the listview, and handle different clicks, as the listview deals with handling the click on a child. Thanks for anyone who could point me in the right direction.

  • Android: Calculator on showing 0 immediately after the dot

    - by pearmak
    I am now working on a calculator, and everything works fine except for decimal places. The calculator contains 2 displays actually, one is called fakedisplay for actual operations, and one is called Display, for presenting the desired format, ie adding commas. When pressing 12345.678, Display will follow fakedisplay and present as 12,345.678, but if i press 12345.009, the fakedisplay will work normally as 12345.009, but the Display stuck as 12,345 until 9 is pressed, and at that time it will show 12,345.009 normally. However, it is strange that when the user presses 0, there is no response, and until pressing 9, 009 will then immediately append. I know this arise from the parsing code, but based on this, how could I amend the following code? I really cannot think of any solution... Many thanks for all your advice! one.setOnClickListener(new View.OnClickListener() { if (str.length()<15) {Fakedisplay.append("1");} DecimalFormat myFormatter1 = new DecimalFormat("###,###,###,###.#################"); String str1=Fakedisplay.getText().toString(); String stripped1 = Double.valueOf(str1).toString(); stripped1 = myFormatter1.format(Double.valueOf(stripped1)); if (stripped1.endsWith(".0")) stripped1 = stripped1.substring(0, stripped1.length() - 2); Display.setText(stripped1);

  • (Android) Why won't invalidate() update my buttons immediately?

    - by frustrated user
    I have read several forums and examples on using invalidate() in order to update views immediately but I still do not understand why what I am doing will not work. The code below uses image buttons defined by "red", "blue", "green", and "yellow". I set a 1 second delay between each time I try and change a button's appearance. Please someone tell me what i'm doing wrong. private void showPattern() { if (correct == true) { for (int k = 0; k < temp_basket.length; k++) { if (temp_basket[k] == 0) { red.setPressed(true); red.invalidate(); final Handler handler = new Handler(); Timer t = new Timer(); t.schedule(new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { red.setPressed(false); red.invalidate(); } }); } }, 1000); There are 3 more or these blocks after this one that are blue, green, and yellow.

  • I'm new one in Android and HELP :)

    - by Kooper
    Hello everyone , I'd started for about a mouth and I have some problems now :( 1. I create a TabActivity and it has three Activity(tab1,tab2,tab3).I wanna realize that if I press a button in tab1,then TextView in tab2 can be changed. I've tried Intent and Bundle , but that didn't work and force close . Maybe because of the TabActivity I think . 2. If I have a layout and there are many TextView on it. But some are out of the screen. How can I scroll the screen? 3. Is it possible that TextView in Tablelayout can be clicked ? I've sreached there problems on Google for there days but still bother me . Really need help, Thanks :)

  • Android preferencesActivity setDefaultValue() not working?

    - by Nick
    I'm extending PreferenceActivity for my settings screen. In this preference activity i have a couple of preferences one of which is custom made. The problem is as follows: in this custom preference (which extends from ListPreference) i want to be able to set the default value, so i override the setDefaultValue() method. In this method i do some parsing so it'll take the correct value. When i'm trying to read this value with the getValue() function it just returns null. So i figured, what happens when i just put some hardcoded value in there (you know, maybe i did something wrong, wouldn't be the first time). Well, i still get null back. Any ideas what i'm doing wrong? Edit: Setting the defaultValue in the xml file isn't really an option because the values aren't known until i retrieve them. I made a workaround: When app is started for the first time: get data Set the values in the preference. This way i set the default preference when i'm collection the data

  • Android Static Variable Scope and Lifetime

    - by Edison
    I have an application that has a Service uses a ArrayList to store in the background for a very long time, the variable is initialized when the service started. The service is in the background and there will be frequent access to the variable (that's why i don't want to use file management or settings since it will be very expensive for a file I/O for the sake of battery life). The variable will likely to be ~1MB-2MB over its life tie. Is it safe to say that it will never be nulled by GC or the system or is there any way to prevent it? Thanks.

  • Android: how to convert whole ImageView to Bitmap?

    - by yosh
    I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case). So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it? On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

  • Android: implementing sliding cards in widget

    - by DroidIn.net
    I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. QUESTIONS: What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?

  • Expression parser library for Android.

    - by Malx
    What is the best way to evaluate simple conditional statements like: "a>b" ? "x-4<10+y & y>x" ? Expressions are loaded from external file. Variables are set in application. Syntax used is not essential. It may be "&" or "and" or any other supported with language/library. I need to take different action depending on result of evaluation - is it true or false. Could I use any parser already included with Andorid? Is there some way to use JS "eval" from browser component? Is it possible to use sqlite expressions to get true/false result without selecting anything? Those libraries are implemented in native code. Will it be faster and less battery expensive?
