Android :: Draw Text In Rectangle?
Aug 4, 2009
I have just started looking at developing for Google Android and want to draw a rectangle with some text in it that I then want to position where i want on screen. I have got as far as drawing a rectangle on screen using a ShapeDrawable and RectShape I now want to put some text in the rectangle. How can I best do this? Should I be looking at somehow adding a textView to the RectShape? Or am i going down the the wrong avenue completely?

Is there any convenient method to draw a string (custom true type font) as big is possible inside a supplied rectangle or to calculate the font size of a paint object based on a string and some rectangle dimensions.

i'm trying to develop a simple pie chart class for android. For now, it can take a map of labels and values and draw the pie chart. I'm yet to add the legends for the pie, which is where i need to place the texts near small rectangles on the screen corner. Any help appreciated, since i'm new to Android dev.

I'm currently developing a small OpenGL game for the Android platform and I wonder if there's an easy way to render text on top of the rendered frame (like a HUD with the players score etc). The text would need to use a custom font also. I've seen an example using a View as an overlay, but I don't know if I want to do that since I might want to port the game to other platforms later.

I have figured out the static layout this far, but I have no idea how to make it display my text anywhere else but in the top left corner. StaticLayout layout = new StaticLayout(text, getTextPaint(), 140, android.text.Layout.Alignment.ALIGN_CENTER,(float)1.0, (float)0.0, true); layout.draw(canvas);

I'm trying to draw some text onto an MapView on Android. The drawing of the text goes fine, but it's very hard to read the text because it's white with no black border (like the rest of the text that appears naturally on MapViews to denote cities, states, and countries). I can't seem to figure how to draw the text with a black border. This is the sort of code I'm using right now (this is just example code, found in one of my overlays):
@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
Paint textPaint = new Paint();
textPaint.setARGB(255, 255, 255, 255);
textPaint.setTextAlign(Paint.Align.CENTER);
textPaint.setTextSize(16);
textPaint.setTypeface(Typeface.DEFAULT_BOLD);
canvas.drawText("Some Text", 100, 100, textPaint);
super.draw(canvas, mapView, shadow);}

I've figured out how to draw Arabic characters properly (connected and right to left) using string literals like this:
textView.setTypeFace(Typeface.createFromAssets(getAssets(),"DejaVuSans.ttf"));
textView.setText("uFEB3uFE92uFE98uFE94");
But for some reason I cannot get the arabic to format properly if I read anything from a file using InputStreams like this:.....................

I'm trying to draw Arabic text onto a Bitmap for display:
CODE:...........
However, the bitmap that is generated looks like this:
When it should look like............
I believe the issue is because, unlike a TextView, the Bitmap class is not BiDi aware, so it draws the letters from left to write.
Try as I might, I can't figure out how to draw the text in the correct order.

I am wondering if there is a way to draw an image, or edit simple lines in a text box. The entire screen is a textView/ect and i would like to be able to write a sentence then draw an image and write again. By draw i think i would use the Canvas, so basically is there a way to include a canvas in a text view?
Evernote does do this, but to edit an image/draw you need to open another app "Skitch", my goal is to try and do this without any extra apps.
For example:
Hello
(canvas/editable graphical items)
World

I can create a shape that is a rectangle with all edges rounded. However, what I'm wanting is a rectangle shape with only 2 of the edges rounded. Is this possible?
I'm essentially hacking together a ListView that looks like a bubble with rounded edges. I'm looking to add a header that has the two top edges rounded and a footer with the two bottom edges rounded.

Will messing around with my Droid, which I love!, I have noticed that the rectangle piece above the batter door gets very warm, and sometimes hot. Is this normal or is something wrong here? I have disabled wifi, bt, gps, the sync feature?, and dimmed the screen to low and nothing seems to fix it. It happens all the time, no matter what I am doing.

I want to have a elmenent with a 2 color border outline. I can do a single color outline using the element, but this only allows me to draw a single line. I tried using 2 elements within my but that didnt work either. Is there a way to either draw a shape within a shape or draw 2 lines around my shape (which has rounded corners btw).

I'm trying to figure out how to draw on a bitmap in android, and keep a copy of these changed bitmaps for an undo function.
Bitmap b = ...
Paint p = new Paint();
canvas.drawBitmap(b, new Matrix(), null);
canvas.drawCircle(0,0,20,20);
//does Bitmap b have the circle drawn on it next time?
Or how do I get the bitmap after its been drawn on with the canvas(I want to preserve a stack of bitmaps with the changes applied by canvas drawing)? Maybe I'm going about this entirely wrong.

I'm investigating the possiblity of writing an app for Android/iOS4/both that would use GPS in the background. I found the "Receiving Location Events in the Background" section of the iphone developer documentation, which recommends that I only register for "significant location change" events. I'm not aware of any such capability in the Android SDK, but it still seems like a good idea to do it this way if I can (so as not to drain the battery). My question is this: has anyone done any sort of benchmarking for this on and iPhone/Android phone? So far, I've seen a lot posts/documentation saying that listening for GPS events in the background is a VERY BAD THING and I should AVOID IT AT ALL COSTS, but I haven't been able to find any numbers for just how much power a background application listening on GPS changes would drain (i.e. % battery drain per time app is running in the background).
This information might be helpful for me (and possibly others too) because I might be able to poll less frequently or even register/unregister my GPS listener based on power drain. Essentially, I could try to put a ceiling on how much battery life my app could drain while in the background.
