i have this code to show gif image with Movie.
public class GIFView extends View{
private Movie movie;
private InputStream is;
private long moviestart;
public GIFView(Context context) {
super(context);
is=getResources().openRawResource(R.drawable.anim_cerca);
movie=Movie.decodeStream(is);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
long now=android.os.SystemClock.uptimeMillis();
if (moviestart == 0)
moviestart = now;
int relTime = (int)((now - moviestart) % movie.duration());
movie.setTime(relTime);
movie.draw(canvas,10,10);
this.invalidate();
}
}
My problem borns when gif is loaded, it draw very bad, only the first frame is shown and the other are like disturbed. What can i do?
EDIT: THE PROBLEM IS EMULATOR! IT DOESN'T SHOW GIF, BUT ON DEVICE IT'S OK! :)
Android devices have not had built-in animated GIF support, which causes GIFs to load slower on some Android phones than on other OS.
Tap on the GIF image that you like and preview it. Press and hold on the image and then select Download image from the pop-up window. Once downloaded, you will be to view the GIF image in the Gallery app.
Good start. Gotta make it more useful for loading different gifs after being added to the view and for either assets or resources. Also, for devices with hardware acceleration I was getting blank views, so I turned it off for this GIFView.
Also, be sure to put animated gifs in the res/drawable-xhdpi directory (or assets if using that way)
public class GIFView extends View{
Movie movie;
long moviestart;
public GIFView(Context context) throws IOException {
super(context);
}
public GIFView(Context context, AttributeSet attrs) throws IOException{
super(context, attrs);
}
public GIFView(Context context, AttributeSet attrs, int defStyle) throws IOException {
super(context, attrs, defStyle);
}
public void loadGIFResource(Context context, int id)
{
//turn off hardware acceleration
this.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
InputStream is=context.getResources().openRawResource(id);
movie = Movie.decodeStream(is);
}
public void loadGIFAsset(Context context, String filename)
{
InputStream is;
try {
is = context.getResources().getAssets().open(filename);
movie = Movie.decodeStream(is);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (movie == null) {
return;
}
long now=android.os.SystemClock.uptimeMillis();
if (moviestart == 0) moviestart = now;
int relTime;
relTime = (int)((now - moviestart) % movie.duration());
movie.setTime(relTime);
movie.draw(canvas,10,10);
this.invalidate();
}
}
Usage:
imageView.loadGIFResource(this, R.drawable.quickguide_1);
and
<com.eyeverify.GIFView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginBottom="50dp"
android:layout_marginTop="110dp"
android:src="@drawable/quickguide_1"/>
