Aggiunta di immagini gif in un ImageView in Android

Ho aggiunto un'immagine gif animata in imageView. Non riesco a vederlo come immagine gif. Non c'è animazione. Appare come un'immagine fissa. Vorrei sapere come posso mostrarlo come immagine gif.

Innanzitutto, copia l'immagine GIF nella Cartella risorse della tua app, crea le seguenti classi e incolla il codice 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);
}
}

GifDecoder: -

public class GifDecoder {

    public static final int STATUS_OK = 0;

    public static final int STATUS_FORMAT_ERROR = 1;

    public static final int STATUS_OPEN_ERROR = 2;

    protected static final int MAX_STACK_SIZE = 4096;
    protected InputStream in;
    protected int status;
    protected int width; // full image width
    protected int height; // full image height
    protected boolean gctFlag; // global color table used
    protected int gctSize; // size of global color table
    protected int loopCount = 1; // iterations; 0 = repeat forever

    protected int[] lct; // local color table

Penso che possa aiutarti ... :)

In build.gradle (Modulo: app), aggiungi android-gif-drawablecome dipendenza aggiungendo il seguente codice:

allprojects {
    repositories {
       mavenCentral()
    }
}

dependencies {
    compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}

dependencies {
    implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}

Quindi sincronizza il tuo progetto. Al termine della sincronizzazione, vai al tuo file di layout e aggiungi il seguente codice:

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/gif_file"
/>

Ed è tutto, puoi gestirlo con un semplice ImageView.

Usa VideoView.

Nativamente ImageView non supporta l'immagine animata. Hai due opzioni per mostrare il file gif animato

1. Uso VideoView
2. Utilizzare ImageViewe dividere il file gif in più parti e quindi applicare l'animazione ad esso

con l'ultima libreria Glide

usa Gradle:

repositories {
  mavenCentral()
  google()
}

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.8.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
}

in attività o frammento:

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);

Mostra GIF in Android

Creare 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();

        }

 }

 }

Ora chiama questa classe nel tuo XML

 <Your_PackageName.CustomGifView
        android:id="@+id/gifview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Modifica AndroidManifest.xml per disattivare l'hardware accelerato.

 android:hardwareAccelerated="false"

http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

Ti consiglierei di usare la libreria Glide. Per usare Glide devi aggiungere questo per aggiungere queste dipendenze

compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:support-v4:23.4.0'

al tuo file grandle (Modulo: app).

Quindi utilizzare questa riga di codice per caricare l'immagine gif

Glide.with(context).load(R.drawable.loading).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).crossFade().into(loadingImageView);

Ulteriori informazioni su Glide

Sulla base del commento di Warlock di Ahmad Dwaik , ho provato il codice seguente e ha funzionato.

1. Usa una visualizzazione web nel tuo file xml e regola la sua posizione nel punto in cui esattamente stavi cercando di mostrarti l'immagine .gif.
2. Nella tua attività inizializza questo piccolo pezzo di webview come altre viste.
3. posizionare l'immagine .gif nella cartella delle risorse
4. ora carica l'immagine come se stessi caricando un URL in visualizzazione Web come "diyaWebView1.loadUrl (" file: ///android_asset/www/diya.gif ");"
5. puoi vedere la tua immagine .gif all'avvio dell'applicazione.

PS: questo funziona se l'immagine .gif si adatta alla tua vista web o viceversa se l'immagine è più grande della vista web la barra di scorrimento viene abilitata e l'utente può scorrere l'immagine webview AKA. Quindi dobbiamo stare attenti quando lo usiamo, per dare le dimensioni adeguate alla visualizzazione web come da immagine o modificare l'immagine adatta alla tua visualizzazione web.

Usa Webview per caricare gif come as

webView = (WebView) findViewById(R.id.webView);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/1.gif");

GIFImageView

public class GifImageView extends ImageView {

    Movie movie;
    InputStream inputStream;
    private long mMovieStart;

    public GifImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public GifImageView(Context context) {
        super(context);
    }

    public GifImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setFocusable(true);
        inputStream = context.getResources()
                .openRawResource(R.drawable.thunder);
            byte[] array = streamToBytes(inputStream);
            movie = Movie.decodeByteArray(array, 0, array.length);

    }

    private byte[] streamToBytes(InputStream is) {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(
                1024);
        byte[] buffer = new byte[1024];
        int len;
        try {
            while ((len = is.read(buffer)) >= 0) {
                byteArrayOutputStream.write(buffer, 0, len);
                return byteArrayOutputStream.toByteArray();
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return null;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        long now = SystemClock.uptimeMillis();
        if (mMovieStart == 0) { // first time
            mMovieStart = now;
        }
        if (movie != null) {
            int dur = movie.duration();
            if (dur == 0) {
                dur = 3000;
            }
            int relTime = (int) ((now - mMovieStart) % dur);
            movie.setTime(relTime);
            movie.draw(canvas, getWidth() - 200, getHeight() - 200);
            invalidate();
        }
    }

}

In XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/update"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="abc" /> 

    <com.example.apptracker.GifImageView
        android:id="@+id/gifImageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" />

</RelativeLayout>

Nel file Java

public class MainActivity extends Activity {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 
        GifImageView gifImageView = (GifImageView) findViewById(R.id.gifImageView1);
        if (Build.VERSION.SDK_INT >= 11) {
            gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }
    }
}

Dobbiamo usare gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);come quando l'hardware accelerato abilitato, l'immagine GIF non funziona su quel dispositivo. L'accelerazione hardware è abilitata sui dispositivi sopra (4.x).

Come ha detto @Ahmad in un commento , puoi semplicemente usare il seguente codice per visualizzare una gif!

Basta semplicemente inserire questo codice nel metodo onCreate e sei a posto! Inoltre, inserisci la tua gif nella assetscartella (se non hai la cartella delle risorse, creane una sotto src/main)

WebView wView = new WebView(this);
wView.loadUrl("file:///android_asset/piggy.gif");
setContentView(view);

Possiamo facilmente aggiungere immagini gif animate su imageview usando la libreria Ion.

Video tutorial: https://www.youtube.com/watch?v=IqKtpdeIpjA

ImageView image = (ImageView)findViewById(R.id.image_gif);
Ion.with(image).load("http://mygifimage.gif");

Questo è ciò che ha funzionato per me:

Nel tuo build.gradle (progetto) scrivi mavenCentral () nel buildscript {} e in tutti i progetti {}. Dovrebbe sembrare come questo:

buildscript {
    repositories {
        jcenter()
        **mavenCentral()**
    }
//more code ...
}
allprojects {
    repositories {
        jcenter()
        **mavenCentral()**
    }
}

Quindi, in build.gradle (modulo) aggiungi le dipendenze {} questo snippet:

compilare 'pl.droidsonroids.gif: android-gif-drawable: 1.2.4'

Dovrebbe sembrare come questo:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    testCompile 'junit:junit:4.12'
    **compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.4'**
}

Inserisci la tua immagine .gif nella tua cartella disegnabile. Ora vai su app> res> layout> activity_main.xml e aggiungi questo frammento per il tuo .gif:

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/YOUR_GIF_IMAGE"
    android:background="#000000" //for black background
    />

E hai finito :)

Spero che questo ti aiuti.

Puoi visualizzare qualsiasi immagine gif tramite la libreria Fresco di Facebook :

Uri uri = Uri.parse("http://domain.com/awersome.gif");
final SimpleDraweeView draweeView = new SimpleDraweeView(context);
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(200, 200);

draweeView.setLayoutParams(params);
DraweeController controller = Fresco.newDraweeControllerBuilder()
        .setUri(uri)
        .setAutoPlayAnimations(true)
        .build();
draweeView.setController(controller);
//now just add draweeView to layout and enjoy

Innanzitutto aggiungi una dipendenza nel module:appfile build.gradle

compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.+'

Quindi, nel file di layout

<pl.droidsonroids.gif.GifImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/mq_app"
        />

Gif può anche essere visualizzato in vista web con un paio di righe di codice e senza librerie di terze parti. In questo modo puoi persino caricare la gif dalla tua scheda SD. Non è necessario copiare le immagini nella cartella delle risorse.

Prendi una vista web.

<WebView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageWebView" />

L'uso può aprire un file gif dalla scheda SD non solo dalla cartella delle risorse, come mostrato in molti esempi.

    WebView webView = (WebView) findViewById(R.id.imageWebView);
    String  data    = "<body> <img src = \""+ filePath+"\"/></body>";
    // 'filePath' is the path of your .GIF file on SD card.
   webView.loadDataWithBaseURL("file:///android_asset/",data,"text/html","UTF-8",null);

Ho riscontrato problemi da usare

compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.+'

Inoltre, non sono riuscito a trovare il file jar da aggiungere al mio progetto. Quindi, per mostrare GIF, uso WebView in questo modo:

WebView webView = (WebView) this.findViewById(R.id.webView);
webView.loadDataWithBaseURL(null, "<html><body><center><img style='align:center;width:250px; height:250px; border-radius:50%' src='file:///android_asset/loading.gif'/></center></body></html>", "text/html", "UTF-8", "");
webView.setBackgroundColor(Color.TRANSPARENT);

Visualizza file GIF in Android

Aggiungi la seguente dipendenza nel tuo file build.gradle.

implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.0'

Nel layout - activity_xxxxx.xmlfile aggiungere il GifImageviewseguente.

<pl.droidsonroids.gif.GifImageView
   android:id="@+id/CorrWrong"
   android:layout_width="100dp"
  android:layout_height="75dp"/>

Nel tuo file Java, puoi accedere a GIF come di seguito.

 GifImageView emoji;
 emoji = (GifImageView)findViewById(R.id.CorrWrong);

import android.app.Activity;
import android.util.Log;
import android.widget.ImageView;
