Screen implementation methods for Android programming (including ScrollView and ListView) _android

This example describes the screen implementation of Android programming. Share to everyone for your reference, specific as follows:

public class Screenshot {//Get screenshots of specified activity, save to PNG file public static Bitmap Takescreenshot (activity activity) {/Vie
  W is the View View view that you need to take a screenshot = Activity.getwindow (). Getdecorview ();
  View.setdrawingcacheenabled (TRUE);
  View.builddrawingcache ();
  Bitmap B1 = View.getdrawingcache ();
  Gets the status bar height Rect frame = new Rect ();
  Activity.getwindow (). Getdecorview (). Getwindowvisibledisplayframe (frame);
  int statusbarheight = Frame.top;
  System.out.println (Statusbarheight);
  Gets the screen length and high int width = Activity.getwindowmanager (). Getdefaultdisplay (). GetWidth ();
  int height = Activity.getwindowmanager (). Getdefaultdisplay (). GetHeight ();
  Remove title bar//Bitmap B = Bitmap.createbitmap (B1, 0, 25, 320, 455);
  Bitmap B = Bitmap.createbitmap (b1, 0, Statusbarheight, width, height-statusbarheight);
  View.destroydrawingcache ();
  Savepic (b, "/sdcard/screen_test.png");
 return b; }//Save to SDcard public static void Savepic (Bitmap B, String strFileName) {FileOutputStream fos = null;
  try {fos = new FileOutputStream (strFileName);
    if (null!= fos) {b.compress (Bitmap.CompressFormat.PNG, N, FOS);
    Fos.flush ();
   Fos.close ();
  } catch (FileNotFoundException e) {e.printstacktrace ();
