View 7 Replies View RelatedI have a problem with designing an UI Android activity. There are two blocks of misplaced graphics on the left and right of the activity - they are two lines just bellow the titlebar with 1px height and about 5-10px width. They cause buttons to break at their left and right parts. I cannot figure out what the problem is. I am using Eclipse with Android SDK 0.9.9. The lines appear not only with the emulator but in a HTC Wildfire (Android 2.1). These lines are also visible in a newly created Android project (HelloWorld).

Is there a way to do a linear layout with multiple lines? I want to lay out a variable set of buttons with variable labels, so I'd like to use a layout that works as a simple horizontal LinearLayout, but with multiple lines, so the buttons spill into a second (or third) line if they don't fit on the first one.

View 9 Replies View RelatedI'm wondering how can I split single line text into few lines. I need it for game. I want to make it in canvas. It will be notification popup, but sometimes text is too long (I draw text canvas.drawText()), and I need to split it and draw in few lines in rows. Anyone knows a good solution? I saw methods mPaint.measureText() or TextUtils . split () , but it isn't so good in my case. Is there other method?

View 2 Replies View RelatedThe Emulator draws line widths VERY incorrectly in OpenGL (GLSurfaceView). See http://www.flickr.com/photos/53002505@N03 for a comparison of the lines drawn correctly (in JOGL) and incorrectly in the emulator. The code also draws correctly on a real device (G1) - looks just like the JOGL screen shot. I believe this is a bug. However, I'm not an OpenGL GURU. Hence I have posted a concise version of the code to demonstrate this problem at at http://gist.github.com/523955 and http://gist.github.com/523961. I hope I am proven wrong about a bug in the emulator, and can find a way to use the emulator for what I want to do.

| right! |
or this:
| Center |
Not this (text centered):

View 1 Replies View RelatedI have a calculator type app that I've developed and it's on the Android Market. It uses two input-lines (EditText) and has always worked well until I updated my Nexus One to Android 2.2.
When I would touch the input line, the soft keypad would pop-up automatically, lift up the focused input line into view, and then I would type in my numbers...no problems. But when I updated to Android 2.2, the soft keypad doesn't lift the focused input line far enough and it's only half in view. Then when I scroll down to the next input line, it doesn't lift up either and it's only about 1/4 of the way into view. Another problem is that, sometimes, when I go back and forth between the two input lines and then try to enter numbers - the numbers don't appear but they do when I scroll left. Hard to explain exactly what is happening but something strange is going on there that didn't happen under my Android 2.1 and other lower versions.
I even tried to change some input line (EditText) statements in my code and also tried to change the way the soft keypad would 'pad' the view to the top but things still didn't work after I recompiled. (android:windowSoftInputMode and android:inputType)
I also wonder if they made the soft keypad in 2.2 a little bigger in height. Does anybody out there with 2.2 mess with an app that has input lines where their softkeypad has to move the input line up into view - does it work for you?
Is there any settings/flags to expand the summary text of a notification to two lines instead of 1? The text I am trying to put is too long and it goes over the visible area? Will try something like (text+"/n"+restOfText) tomorrow but I don't think it's going to work...
View 5 Replies View RelatedI have a long text and I want it to be displayed with a TextView. The text I have is much longer than the available space. However I don't want to use scrolling, but ViewFlipper to flip to the next page.

I simply have to use a custom View with a StaticLayout like this:
public ReaderColumView(Context context, Typeface typeface, String cText) { super(context);
Display display = ((WindowManager)
context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
dWidth = display.getWidth(); dHeight = display.getHeight();
contentText = cText; tp = new TextPaint();
tp.setTypeface(typeface); tp.setTextSize(25);
tp.setColor(Color.BLACK); tp.setAntiAlias(true);
StaticLayout measureLayout = new StaticLayout(contentText, tp, 440, Alignment.ALIGN_NORMAL, 1, 2, true);
Boolean reachedEndOfScreen = false;
int line = 0; while (!reachedEndOfScreen) {
if (measureLayout.getLineBottom(line) > dHeight-30) { reachedEndOfScreen = true;
fittedText = contentText.substring(0, measureLayout.getLineEnd(line-1));
setLeftoverText(contentText.substring(measureLayout.getLineEnd(line-1)));
} line++;
} } protected void onDraw(Canvas canvas) { super.onDraw(canvas);
StaticLayout textLayout = new StaticLayout(fittedText, tp, 440, Alignment.ALIGN_NORMAL, 1, 2, true);
canvas.translate(20,20); textLayout.draw(canvas);
}
Thats not optimized yet but you get the point.
I am trying to put CheckBox with multiple lines and all lines after fist with smaller font size same as we have under from home page Menu->Settings->Sound & Display->Silent mode. It shows text "Silent mode" on first line and then some more text (kind of help/current settings) for this option and still CheckBox itself is aligned in the center of all the lines (may be on left or right side). Is that can be done by only one control/widget or group of many controls/widgets?I can only think of by using table but it is complex.
View 3 Replies View RelatedIs there a simple line of code that would allow only loading the code if the OS version meets the requirements? Lets say I have my target OS as 2.2 but the min sdk is 3 for android 1.5 so even if i have some code in my project that isn't compatable with 1.5 it will still compile since the target OS is 2.2. Anyway, I want to ad a feature that requires code that's not in the 1.5 SDK and will cause a crash if it's loaded on a 1.5 phone. Is there a simple thing like this that I can do? So i dont have to make the entire app not available to 1.5 users?

//Insert code here that requires 2.1 and up}

I am developing the camera module for an android application. In main application when user clicks on 'take picture' button, new view with SurfaceView control is opened and camera preview is shown. When users click on dpad center, camera takes picture and save it to the disc. Pretty simple and straightforward.
Everything works fine on my device - HTC Tattoo, minsdkversion 1.6...but when I tested application on HTC Hero minsdkversion 1.5, when camera preview is shown,some strange lines occur. altough preview is crashed, taking of pictures works fine

Does anyone know how to display points, lines etc. (basically every overlay) created in android in standard google maps on website? The android db is synchronized with remote db. I'm getting the points from the database, creating kml file from them and uploading in to the map. The problem is that the areas I've created are not appearing where they should. They're somewhere on the ocean.
I thought that's because I'm running this code in android:

what is best way to create app in which I only need to draw simple lines through onTouchEvent? When i use invalidate everytime i draw any line, that erase lines i draw before. But if I use some List structure to store drawed lines it lose performance. Is there any simple way to do it?
View 6 Replies View RelatedI am working on a paint application for Android. Now I want to implement an eraser to allow erasing parts of a loaded bitmap by using touch input and making the bitmap transparent along the finger's path.
A very good example of what I try to achieve is shown in the application Steamy Window for Android. Steamy Window simulates a fogged window, where a user can wipe parts of the fog via touch input.

What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:
INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);
but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?
My application uses a list of media files on the phone, i.e. images, audio and video. It also allows the user to filter the list via some checkboxes in a menu, so the user can choose to show or hide each type of files. The way I've been doing this is by putting this in the adapter's getView():
// don't show unwanted file types if (cmo.hasType(MediaType.AUDIO_FILE)){
if(!prefs.getBoolean(PREFS_SHOWAUDIO, true)){ return new ViewStub(mContext);;
} }else if(cmo.hasType(MediaType.IMAGE_FILE)){ if(!prefs.getBoolean(PREFS_SHOWIMG, true)){
return new ViewStub(mContext);;
} }else if( cmo.hasType(MediaType.VIDEO_FILE)){ if(!prefs.getBoolean(PREFS_SHOWVIDEO, true)){ return new ViewStub(mContext);; } }
Which is quite effective in the sense that the list doesn't show those elements. However, the ListView still renders a 1px grey line between each View, even if they are ViewStubs, meaning I see a thick gray line whenever a group of consecutive items are filtered away. How can I get rid of those lines? Should I create a new data array, containing only the elements that should show a view?
I am drawing several lines on a canvas using drawline, the lines are semi transparent (their paint has an alpha value <255) only problem is that the point at which they cross creates a dot of less transparent color (obviously) is there a simple way to avoid this?
View 1 Replies View RelatedI'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.
One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.

I tried enough to find in google & android this question. Also did several trials & errors, but couldn't get this question. was learning Android's "Draw Nine Patch" images. One basic I know is that, whatever image you process must be in .png format (if it's already in .9.png then it will be ignored by tool). However, couldn't understand what it literally means by "stretchable patches" ? what exactly happens when you draw black dots outside the .png image ? (preview pane shows changes happening, but I am unclear on how it makes those)When I draw black dots in left/top sides of image it shows some changes in preview; but why isn't there any effect when you do the same on right/bottom side of the image ? why this tool is used primarily for background, when we try to process on the image itself ?i am trying to modify a simple button.png (given in android sdk). Whenever I use this tool & draw black lines, it reduces the size of the image instead of 'stretching' it! Why ?What is the significance of options given below like, "show lock", "show content", "Patch scale" and so on ?I apologize for asking so many questions, but in Android online docs they haven't explained well for novice. If someone can answer these, it will become ready reference for all the begineers who search this forum.
