Android :: Draw GLSurfaceView To A Bitmap

Nov 4, 2009

I have an application that uses GLSurfaceView to draw OpenGL ES graphics. This is all working (mostly) how I would expect.

Now, I would like to implement a screenshot feature. For normal views, it seems that the standard practice is to create a new Canvas with a Bitmap and then draw to that Canvas using View.onDraw(Canvas).

I've tried using SurfaceView.draw(Canvas) in a similar fashion, but it always results in a blank (black) image.

I've also tried using the drawing cache with the exact same result.

Android :: Draw Text In OpenGL ES

Aug 27, 2009

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.

Android :: Using StaticLayout With Canvas To Draw Text

Feb 4, 2010

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);

Android :: Draw Text With Border On MapView?

Nov 12, 2009

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);}

Android :: Draw Arabic Text After Reading From File?

Sep 26, 2010

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:.....................

Android :: Draw RTL Text - Arabic - Onto Bitmap And Have Ordered Properly

Sep 13, 2009

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.

How To Draw Image Or Edit Simple Lines In Text Box

Jan 8, 2013

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)

Android :: GLSurfaceView And Key Presses

Nov 30, 2009

Following the samples and examples, I've successfully been able to load a model on screen and rotate it with the DPAD keys and overriding the onKeyDown method of the GLSurfaceView. Trying to use a letter though, causes a small box to appear at the bottom accepting the text that is being typed. What I'm not entirely clear on, is since I don't have a listener defined in the main Activity, why those key letter key presses are being intercepted by some other inherent listener(?). I setup an OnKeyListener for the view to call my own method and that does work... but I'm wondering if there is perhaps a better way to handle it.

Android :: Set EglSwapInterval When Using GLSurfaceView?

Sep 3, 2010

I am a lazybones using GLSurfaceView and loving it. But now that my code is running too darn fast (heh), I would like to slow it down via setting eglSwapInterval to 2 or something. Just to be nice to the battery. But, being a lazybones, I can find no way of doing this when using GLSurfaceView. (and hacking an early return from onDrawFrame() was very unsatisfying).

Android :: Deadlock In GLSurfaceView

Jul 27, 2009

We are developing an application that uses a GLSurfaceView to display 3D objects. We regularly get the "Application Not Responding" dialog. Inspection of the dumped threads reveals something that looks suspiciously like a deadlock. I have added the three thread dumps involved below. The first thread is the main application event thread, and it is waiting on a join with a GLThread.

The second thread is a brand new GLThread that is waiting for a semaphore lock presumably so it knows it has exclusive access to the graphics hardware. The third thread is probably a previous GLThread (the one the main thread is waiting for to finish), that is waiting to be notified. The strange thing is that the main application thread has just done a "mDone=true; notify();" prior to calling "wait()", so the third thread should have been awaken? .........................

Android :: Screen Flickering In GLSurfaceView

Mar 18, 2010

I'm using GLSurfaceView to create a simple OpenGL drawing application. Since the elements drawn in each frame must remain on screen in order to be composed into the whole drawing, I don't use gl.glClear(GL10.GL_COLOR_BUFFER_BIT) at the beginning of each frame. But not clearing the color buffer leads to substantial flickering. Is there any way to eliminate flickering while still not clearing the screen at the beginning of each frame?

Android :: How To Overlay GLSurfaceView Over A CameraPreview?

Sep 22, 2010

I am trying to merge two examples from the ApiDemos so one overlay over the other. 1. CameraPreview.java 2. TranslucentGLSurfaceViewActivity.java I guess GLSurfaceView is not really necessary, I saw demos that uses a GL layer as a Camera PreviewCallback, but since I am such a noob at OpenGL, I am kind of lost. Can someone points me toward the light (figuratively speaking)?
