Android implements the method of saving view into bitmap _android

The example in this article describes how the Android implementation saves view to bitmap. Share to everyone for your reference, specific as follows:

1,

Public Bitmap Convertviewtobitmap (view view) {
    Bitmap Bitmap = Bitmap.createbitmap (View.getwidth (), View.getheight (),
        Bitmap.Config.ARGB_8888);
    Using bitmap to generate canvas
    Canvas Canvas = new Canvas (bitmap);
    Draw the contents of the view on the canvas
    view.draw (canvas);
  return bitmap;
}

2,

/** * Save View as a bitmap/private bitmap Saveviewbitmap (view view) {//Get current
  View Bitmap view.setdrawingcacheenabled (true);
  View.builddrawingcache (TRUE);
  Bitmap Bitmap = View.getdrawingcache (true);
  Bitmap bmp = Duplicatebitmap (BITMAP);
  if (bitmap!= null &&!bitmap.isrecycled ()) {bitmap.recycle (); bitmap = null;}
  Clear the cache view.setdrawingcacheenabled (false);
return BMP;
  public static Bitmap Duplicatebitmap (Bitmap bmpsrc) {if (null = = BMPSRC) {return null;}
  int bmpsrcwidth = Bmpsrc.getwidth ();
  int bmpsrcheight = Bmpsrc.getheight (); Bitmap bmpdest = Bitmap.createbitmap (Bmpsrcwidth, Bmpsrcheight, config.argb_8888);
  if (null!= bmpdest) {Canvas Canvas = new Canvas (bmpdest); final Rect Rect = new Rect (0, 0, bmpsrcwidth, bmpsrcheight); Canvas.drawbitmap (BMPSRC, rect, rect, null);
return bmpdest; }
