android-canvas

I am doing the below. All I get is the basic font, not my custom symbol font. Any ideas? Paint pnt = new Paint(); // SymbolNo is 38. Returns string "&" which is correct in normal font. String symbolText = Character.toString((char)SymbolNo); // Should adopt a symbol font and draw symbol to screen instead. But I just see "&" Typeface tf = Typeface.createFromAsset(m_context.getAssets(), "fonts/myFont.TTF" ); pnt.setTypeface(tf); m_canvas.drawText(symbolText,x, y, pnt); my font is in assets/fonts/myFont.TTF Not every font works with Android. It just silently fails. One course of action is to find

I set a matrix to my canvas in the onDraw method of a custom view via canvas.setMatrix(matrix); then I just draw a grid using predefined paints: canvas.drawRect(0,0,viewWidth,viewHeight, background); for(int i=0; i <= nRows; i++){ canvas.drawLine(0,i*cellHeight, nCols*cellWidth,i*cellHeight,lines); canvas.drawLine(i*cellWidth, 0, i*cellWidth, nRows*cellHeight, lines); if(i != nRows) canvas.drawText(""+i, i*cellWidth, (i+1)*cellHeight, text); } and for some reason the whole canvas is offset by about 1.5 times the height of a cell. Any idea why this is happening or how to fix it? The matrix was

i want my Bitmap that has the height of the screen and has a bigger width than the screen to be moved a little bit to the right or left if the user changes the desktop so he can see the entire image. Here is my code that just works partially: int x = -1*(int)((xOffset*bmp.getWidth())); canvas.drawBitmap(bmp, x, 0, null); thank you! George Freeman You get exact pixel values via the variables xPixels and yPixels in onOffsetsChanged(). See my answer here: android live wallpaper rescaling For example, in onOffsetsChanged(), you can set a private class variable mPixels = xPixels; Then, in your draw

I have a gear image which I want to continuously rotate about a fixed point. Earlier I was accomplishing this by including the image in my Android class as an ImageView and applying a RotateAnimation to it. @InjectView(R.id.gear00) ImageView gear00; RotateAnimation ra07 = new RotateAnimation(0, 359, 129, 186); ra07.setDuration(10000); ra07.setRepeatCount(RotateAnimation.INFINITE); ra07.setInterpolator(new LinearInterpolator()); gear00.setAnimation(ra07); Basically, I was injecting the ImageView into the class and applying a rotation animation. However, I dont have the luxury of using an

background i have a master bitmap that i need to draw on it other bitmaps. the master bitmap has some semi-transparent pixels (pixels with variant values for the alpha channel) , so that the other bitmaps that are drawn on it should be merged with it instead of overriding the colors completely. the question how can i set the canvas to draw the bitmaps on the master bitmap with respect to the semi-transparent pixels ? note: the alpha is not for the whole bitmap/s . it's per pixel. Canvas.setXfermode(Xfermode xfermode) . There are a number of Xfermode s you can choose. Desmond Yao public void
