This example demonstrates how do I display animated gif images in android. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml.
Android smartphones have a built-in image viewing application called Gallery. When you connect your Android smartphone to your computer and transfer a GIF file to your phone's storage area, you can open the Gallery appliation and view that GIF file.
In your build.gradle(Module:app), add android-gif-drawable as a dependency by adding the following code:
allprojects {
repositories {
mavenCentral()
}
}
dependencies {
compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}
implementation, so the above line might have to be changed to:
dependencies {
implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}
Then sync your project. When synchronization ends, go to your layout file and add the following code:
<pl.droidsonroids.gif.GifImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/gif_file"
/>
And that's it, you can manage it with a simple ImageView.
First, copy your GIF image into Asset Folder of your app create following classes and paste the code AnimationActivity: -
public class AnimationActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
InputStream stream = null;
try {
stream = getAssets().open("piggy.gif");
} catch (IOException e) {
e.printStackTrace();
}
GifWebView view = new GifWebView(this, "file:///android_asset /piggy.gif");
setContentView(view);
}
}

I Think It Might Help You... :)
with latest Glide library
use Gradle:
repositories {
mavenCentral()
google()
}
dependencies {
implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
}
in activity or fragment:
ImageView imageView = findViewById(R.id.imageView);
/* from internet*/
Glide.with(this)
.load("https://media.giphy.com/media/98uBZTzlXMhkk/giphy.gif")
.into(imageView);
/*from raw folder*/
Glide.with(this)
.load(R.raw.giphy)
.into(imageView);
Use VideoView.
Natively ImageView does not support animated image. You have two options to show animated gif file
VideoView
ImageView and Split the gif file into several parts and then apply animation to itCreate CustomGifView.java which extends View Class
public class CustomGifView extends View {
private InputStream gifInputStream;
private Movie gifMovie;
private int movieWidth, movieHeight;
private long movieDuration;
private long mMovieStart;
public CustomGifView(Context context) {
super(context);
init(context);
}
public CustomGifView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public CustomGifView(Context context, AttributeSet attrs,
int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(context);
}
private void init(Context context){
setFocusable(true);
gifInputStream = context.getResources()
.openRawResource(R.drawable.YOUR_IMAGE);
gifMovie = Movie.decodeStream(gifInputStream);
movieWidth = gifMovie.width();
movieHeight = gifMovie.height();
movieDuration = gifMovie.duration();
}
@Override
protected void onMeasure(int widthMeasureSpec,
int heightMeasureSpec) {
setMeasuredDimension(movieWidth, movieHeight);
}
public int getMovieWidth(){
return movieWidth;
}
public int getMovieHeight(){
return movieHeight;
}
public long getMovieDuration(){
return movieDuration;
}
@Override
protected void onDraw(Canvas canvas) {
long now = android.os.SystemClock.uptimeMillis();
if (mMovieStart == 0) { // first time
mMovieStart = now;
}
if (gifMovie != null) {
int dur = gifMovie.duration();
if (dur == 0) {
dur = 1000;
}
int relTime = (int)((now - mMovieStart) % dur);
gifMovie.setTime(relTime);
gifMovie.draw(canvas, 0, 0);
invalidate();
}
}
}
Now call this class in your XML
<Your_PackageName.CustomGifView
android:id="@+id/gifview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
N.P
android:hardwareAccelerated="false"
Reference
Another Tricks
For animation functionality you may visit
http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html
I would suggest you to use Glide library. To use Glide you need to add this to add these dependencies
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:support-v4:23.4.0'
to your grandle (Module:app) file.
Then use this line of code to load your gif image
Glide.with(context).load(R.drawable.loading).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).crossFade().into(loadingImageView);
