Implementation method of Android software starting animation and jumping after animation

An example of Android software startup animation and the implementation of the end of animation jump method. To share for your reference, the details are as follows:

I wrote a small program, the software started, first show a few pictures, every 3 seconds to show 1, the picture shows jump to the home page

1. Gallery is used for image broadcast, which 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);// Center the image 
    imageView.setLayoutParams(new Gallery.LayoutParams(
      Gallery.LayoutParams.FILL_PARENT, mImageHeight));
    Bitmap bitmap = readBitMap(mContext, imageId);// Use memory saving way to load the image, prevent OOM
    imageView.setImageBitmap(bitmap);
    overridePendingTransition(R.anim.push_in, R.anim.push_out);// Image toggle animation 
   }
   return imageView;
  }
}

2. Set image switching time using Timer timer

Timer timer = new Timer();
timer.schedule(task, 3000, 3000);//  every 3 Seconds to switch 1 image 
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);
   }
  }
};
// Not directly in task In the update UI , so use handler Send a message to the main thread 
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 the local resource image

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 images 
  InputStream is = context.getResources().openRawResource(resId);
  return BitmapFactory.decodeStream(is, null, opt);
}
