hi all, I wrote following code.
class MyView extends View { Bitmap bitmap; public MyView(Context context) { super(context); Drawable drawable = context.getResources().getDrawable(R.drawable.icon); bitmap = Bitmap.createBitmap(100, 100, true); Canvas canvas = new Canvas(bitmap); drawable.setBounds(0, 0, 100, 100); drawable.draw(canvas); } @Override protected void onDraw(Canvas canvas) { Paint paint = new Paint(); paint.setARGB(255, 255, 255, 255); canvas.drawRect(0, 0, screenWidth, screenHeight, paint); canvas.drawBitmap(bitmap, 10, 10, null); int[] imagedata = new int[100 * 100]; bitmap.getPixels(imagedata, 0, 100, 0, 0, 100, 100); bitmap.setPixels(imagedata, 0, 100, 0, 0, 100, 100); invalidate(); try { Thread.sleep(100); } catch (InterruptedException e) { } } int screenWidth, screenHeight; @Override protected void onSizeChanged(int i, int j, int k, int l) { screenWidth = i; screenHeight = j; super.onSizeChanged(i, j, k, l); } } These code just retrieve the pixel data and then put them back. But why i got different result on the screen. It seems like the retrieve method change some pixel? Can anybody help me with this please? Thanks.
