• Android Tile Bitmap

  - by Rich Lawrence

  I'm trying to load a bitmap in Android which I want to tile. I'm currently using the following in my view to display a bitmap: canvas.drawBitmap(bitmap, srcRect, destRect, null) I essentially want to use this bitmap as a background image in my app and would like to repeat the bitmap in both the X and Y directions. I've seen the TileMode.REPEAT constant for the BitmapShader class but am unsure if this is to do with repeating he actual bitmap or to do with applying a filter to the bitmap.

• Android: RTL support - digits embedded in a right to left sentence (Hebrew)

  - by Rob

  Hi There, My application displays Hebrew text which comes from a Web Service. When a sentence contains digits (in the middle of it), the digits appear in a mirror view: 29 appears as 92, 21:45 appears as 54:12 and 2,000 appears as 000,2. Also, when a sentence starts with digits or English characters, they get thrown to the end of the sentence messing it all up... Does anyone have an idea how can this be solved? Is RTL support in Android still immature? Thanks, Rob
