This article describes the Android software startup animation and animation after the end of the implementation of the jump. Share to everyone for your reference, specific as follows:

I wrote a small program, software startup, first show a few pictures, every 3 seconds to display a picture, show the end of the jump to the home page

1. The picture Carousel uses gallery, the usage is very simple

Galleryadapter adapter = new Galleryadapter (this, mIds);
Mgallery.setadapter (adapter);

Galleryadapter is a custom adapter

public class Galleryadapter extends Baseadapter {private context mcontext;
  private int mimageheight;
  Private int[] MIds;
   Public Galleryadapter (context context, int[] ids) {This.mcontext = context;
   This.mids = IDs;
  Init ();
  private void Init () {mimageheight = Px2dip (Mcontext, Getscreenheight (mainactivity.this));
  @Override public int GetCount () {return mids.length;
  @Override public Object getitem (int position) {return position;
  @Override public long getitemid (int position) {return position;  @Override public View getview (int position, View Convertview, ViewGroup parent) {Final ImageView ImageView = new
   ImageView (Mcontext);
    if (position < mids.length) {int imageid = mids[position]; Imageview.setscaletype (ImageView.ScaleType.CENTER_CROP)//Set picture centered Imageview.setlayoutparams (new
    Gallery.layoutparams (Gallery.LayoutParams.FILL_PARENT, mimageheight)); Bitmap Bitmap = Readbitmap (Mcontext, IMAGeid////////////////////////////////
  Overridependingtransition (r.anim.push_in, r.anim.push_out);//Picture Toggle Animation} return ImageView;

 }
}

2. Set picture switching time using timer timer

Timer timer = new timer ();
Timer.schedule (Task, 3000, 3000); Toggle a picture every 3 seconds
private timertask task = new TimerTask () {@Override public
  void run () {message Message
   = new Message ();
   message.what = 0;
   index = Mgallery.getselecteditemposition ();
   Handler.sendmessage (message);
   index++;
   if (index = = mids.length-1) {
    this.cancel ();
    MainActivity.this.finish ();
    Intent Intent = new Intent (mainactivity.this, test.class);
    StartActivity (intent);
   }
  }
;
You cannot update the UI directly in a task, so send a message to the main thread with Handler
private Handler Handler = new Handler () {
  @Override public
  Void Handlemessage (Message msg) {
   super.handlemessage (msg);
   Switch (msg.what) {case
   0:
    mgallery.setselection (index);
    break;
   Default: Break;}}
;

3. Read local resource picture

public static Bitmap Readbitmap (context context, int resid) {
  bitmapfactory.options opt = new Bitmapfactory.options () ;
  Opt.inpreferredconfig = Bitmap.Config.RGB_565;
  Opt.inpurgeable = true;
  Opt.ininputshareable = true;
  Get resource picture
  InputStream is = Context.getresources (). Openrawresource (RESID);
  Return Bitmapfactory.decodestream (IS, null, opt);
}
