I am trying to put a background image and draw on top of that screen. I assumed activity will have a on draw method, but it does not have. it seems i need to use surfaceview. Can I put a surfaceview on top of the image view and make it transparent ? any example/tutorial i can refer to ?

I've the following code I'm trying to run on emulator ( v 1.5 of OS), but it seems like I can't use the whole canvas! Code...
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.

View 3 Replies View RelatedI'm trying to create on of these images, but Eclipse won't accept it once I've used the draw9patch tool. I've found other people having the same problem, and saw this comment: I discovered later that the problem I was having was caused by the image not being exactly true to the nine-patch spec as defined in the documentation. Once I fixed the image to have a clean (i.e., no gradients etc) one pixel border it was fine. "'m not much good when it comes to image design. What does this mean, how do I create my original png file to meet the specification for Nine Patch?

I'm having a small problem with drawing a View offscreen to a Bitmap. The View is created using LayoutInflater.inflate(int resource, ViewGroup root) with null passed to the root parameter. The View has a fixed size (200x180 pixels). I can create a Bitmap for this View either by using the method View.getDrawingCache() or by calling View.draw(Canvas canvas) using a Canvas that in turn has a backing Bitmap. This works fine if the View doesn't change after the inflate. However, if I have a TextView inside my View that I will update, the size of the TextView is never updated regardless of what method I call on the View (requestLayout(), forceLayout() invalidate() etc.). If I display the View on screen directly, everything works fine (sizes are updated as needed, etc.). What is the correct way of drawing Views off screen and being able to update their layout when needed?
View 3 Replies View RelatedI'm trying to create a custom widget which looks lick HTML table. I chose to derive from TableLayout, which is the subclass of ViewGroup and View. What's confusing me is that the drawing I put into my override of View.onDraw did not take effect, until I moved the codes to the override of ViewGroup.dispatchDraw. I know dispatchDraw is a good place to draw something, but I'm just wondering why there's such difference in my practice?

View 1 Replies View RelatedI 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:

I'm working with Android 2.1 and have the following problem:
Using the method View.getDrawingCache() always returns null. getDrawingCache() should return a Bitmap, which is the presentation of View's content.
Example code:
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final View view = findViewById(R.id.ImageView01);
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
final Bitmap bmp = view.getDrawingCache();
System.out.println(bmp);
}
I've already tried different ways to configure the View object for generating the drawing cache (e.g. View.setWillNotDraw(boolean) and View.setWillNotCacheDrawing(boolean)), but nothing works. What is the right way, or what I'm doing wrong? In real code I want to apply getDrawingCache() on a ViewGroup like RelativeLayout. Is the behaviour the same when using a ViewGroup?

I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.
Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);
I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?
