Android :: Drawpostext Calculate Character Height Draws?

Mar 15, 2010

drawPosText(char[] text, int index, int count, float[] pos, Paint paint) Draw the text in the array, with each character's origin specified by the pos array. Does anyone know where exactly does drawPosText consider the "origin" to be, since you are specifying "origin" as coordinate pairs; i.e., is it bottom-left of character, center, what? Also how does drawPosText calculate character height when it draws?

Android :: String Manipulation Insert Character Every 4th Character

Nov 12, 2010

In Android if I have an edit text and the user entered 123456789012, how could I get the program to insert a dash every 4th character. ie: 1234-5678-9012? I guess you need to say something along the lines of:- a=Characters 1~4, b=Characters 5~8, c=Characters 9-12,

Android :: Button Draws Normal State After Pressing

Mar 30, 2010

I'm new to Android and just starting the very basics. I implement my custom button skin using .9.png images for norma/focus/pressed states. It works fine, but I noticed that after a pressed the focussed button it visually "lost" focus and draws the normal state frame. I planned to use different state images to highloght what button is selected right now, but it seems that it would not work. I noticed also that the same happens with the default LAF button. Is it OK, or it's just emulator issue? What the good workaroud can be used?

Android : Min Height Fill_parent And Height Wrap_content In ScrollView - Or Just The Email App Compose Layout's Code

Oct 7, 2010

If I have the following:

CODE:..............

How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"

layout_height="fill_parent" seems to not do anything if you put them in a scrollview

A working example of what I want is the email app compose window

I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough

CODE:...................

Android :: How To Get Button's Height To Match Another Element's Height

Nov 15, 2010

I want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:

The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?

Create App That Draws A Map Reading Data From Text File?

Oct 12, 2011

I have to create an app that draws a map reading data from a text file : for example the text file can be like

. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3

so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"

next, when i have all the data, draw a simple image rappresenting the data..

my questions are...

there is a function like fscanf?

and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL

Android : RelativeLayout Height Not Following GridView Height

Aug 28, 2010

I am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:

CODE:.................

What I should do to have the height of the RelativeLayout follow the full length of the gridView?

Here is the screenshot: http://tinypic.com/r/98rs4n/4

Android :: Need To Calculate Rotation Vector

May 18, 2010

I need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ So i bet there is a simple solution how to recall the values of sensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me. Code...

How much space does a TextView take?

When I declare a TextView, is it possible to calculate how much space (height and width) it is going to take when actually rendered on the phone?

Android : Calculate An Appropriate Field Width?

Sep 18, 2010

In my app I am displaying a table where the individual cells are editable text fields (i.e. EditText objects). I am currently struggling calculating appropriate widths for these.

If I set the width to be as many "Ems" as the displayed text has characters, my fields are much to wide by about a factor of 2 and the table looks ugly and wastes lots of precious screen space. Setting the width in "Ems" is essentially like assuming the worst case, i.e. the width of a string under the assumption that it contains only the broadest characters in a font, usually 'M' (hence the name of the method), 'm', 'W', or '_'). But on average strings contain narrower characters and so most of these fields are half empty and much too wide for their actual content. I am thus desperately seeking a way to calculate a better fitting width, not that worst case width.

The "normal" way to do this in Java (in AWT or Swing at least) is to asks a widget's current Font (actually a Font's FontMetrics), to calculate and return the width that will be necessary to display a given string in pixels. But how does one obtain a TextView's Font? I haven't found any method to obtain a (Text)View's font and/or calculate a more appropriate width given the actual content of a cell's text string. How does one do that in Android?

Android : Way To Calculate SpannableString Witdh

Nov 22, 2010

I'm building a text at runtime that will be put into a TextView. This text has composed with different size fonts. I must calculate the width in pixels of this text. I have tried to use Paint.measureText, but it does not consider the different font sizes.
How can I calculate the real width?

this is an example: code..

In this example, if I set the relative size to "2f " or "3f"(for example), the total size that returns "MeasureText" is the same.
