You can find sample code in the Android SDK samples. The gif image is displayed in activity that extends View

The code to use gif image other than ImageView is

import android.app.Activity;
import android.content.Context;
import android.graphics.*;
import android.graphics.drawable.*;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.*;

import java.io.IOException;
import java.io.InputStream;
import java.io.ByteArrayOutputStream;

public class BitmapDecode extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(new SampleView(this));
    }

    private static class SampleView extends View {
        private Bitmap mBitmap;
        private Bitmap mBitmap2;
        private Bitmap mBitmap3;
        private Bitmap mBitmap4;
        private Drawable mDrawable;

        private Movie mMovie;
        private long mMovieStart;

        private static byte[] streamToBytes(InputStream is) {
            ByteArrayOutputStream os = new ByteArrayOutputStream(1024);
            byte[] buffer = new byte[1024];
            int len;
            try {
                while ((len = is.read(buffer)) >= 0) {
                    os.write(buffer, 0, len);
                }
            } catch (java.io.IOException e) {
            }
            return os.toByteArray();
        }

        public SampleView(Context context) {
            super(context);
            setFocusable(true);

            java.io.InputStream is;
            is = context.getResources().openRawResource(R.drawable.beach);

            BitmapFactory.Options opts = new BitmapFactory.Options();
            Bitmap bm;

            opts.inJustDecodeBounds = true;
            bm = BitmapFactory.decodeStream(is, null, opts);

            // now opts.outWidth and opts.outHeight are the dimension of the
            // bitmap, even though bm is null

            opts.inJustDecodeBounds = false;    // this will request the bm
            opts.inSampleSize = 4;             // scaled down by 4
            bm = BitmapFactory.decodeStream(is, null, opts);

            mBitmap = bm;

            // decode an image with transparency
            is = context.getResources().openRawResource(R.drawable.frog);
            mBitmap2 = BitmapFactory.decodeStream(is);

            // create a deep copy of it using getPixels() into different configs
            int w = mBitmap2.getWidth();
            int h = mBitmap2.getHeight();
            int[] pixels = new int[w*h];
            mBitmap2.getPixels(pixels, 0, w, 0, 0, w, h);
            mBitmap3 = Bitmap.createBitmap(pixels, 0, w, w, h,
                                           Bitmap.Config.ARGB_8888);
            mBitmap4 = Bitmap.createBitmap(pixels, 0, w, w, h,
                                           Bitmap.Config.ARGB_4444);

            mDrawable = context.getResources().getDrawable(R.drawable.button);
            mDrawable.setBounds(150, 20, 300, 100);

            is = context.getResources().openRawResource(R.drawable.animated_gif);
            if (true) {
                mMovie = Movie.decodeStream(is);
            } else {
                byte[] array = streamToBytes(is);
                mMovie = Movie.decodeByteArray(array, 0, array.length);
            }
        }

        @Override protected void onDraw(Canvas canvas) {
            canvas.drawColor(0xFFCCCCCC);            

            Paint p = new Paint();
            p.setAntiAlias(true);

            canvas.drawBitmap(mBitmap, 10, 10, null);
            canvas.drawBitmap(mBitmap2, 10, 170, null);
            canvas.drawBitmap(mBitmap3, 110, 170, null);
            canvas.drawBitmap(mBitmap4, 210, 170, null);

            mDrawable.draw(canvas);

            long now = android.os.SystemClock.uptimeMillis();
            if (mMovieStart == 0) {   // first time
                mMovieStart = now;
            }
            if (mMovie != null) {
                int dur = mMovie.duration();
                if (dur == 0) {
                    dur = 1000;
                }
                int relTime = (int)((now - mMovieStart) % dur);
                mMovie.setTime(relTime);
                mMovie.draw(canvas, getWidth() - mMovie.width(),
                            getHeight() - mMovie.height());
                invalidate();
            }
