How to add Text on Android Live Wallpapers
Im doing Android Live Wallpaper.It provides the user to give text input dyn开发者_如何学编程amically.That text should be displayed on wallpaper or scrolling like that.And this wallpapers have to be set as background.How could i do this.?
You can use this.
final SurfaceHolder holder = getSurfaceHolder();
try {
Canvas _canvas = holder.lockCanvas();
if (_canvas != null)
{
drawAnimation(_canvas);
}
}
finally
{
if (_canvas != null)
holder.unlockCanvasAndPost(_canvas);
}
and then in your drawAnimation function
private void drawAnimation(Canvas c)
{
c.drawText(text, x, y, paint);
}
You can use this and you can see if y>height_screen first line replace to second line and after that second line will be a first line. And you can do this for all line, after that you will see that your last line will be empty, add your new text in last line. I hope it helps you.
