J'ai vraiment besoin d'aide s'il vous plaît. J'ai une application autonome de type bande dessinée. Les images sont retournées en utilisant le geste de retour pour tourner la page d'avant en arrière Cependant, j'ai désespérément besoin de la possibilité de zoomer pour chaque image/panneau. Ceci est une galerie plus grande: S'il vous plaît aidez-moi à ajouter des fonctionnalités de zoom à ce code! merci S'il vous plaît ne me réfère pas à des choses déjà publiées ici sur stackoverflow j'ai lu tout cela et il ne me aide jusqu'ici ...Android Zoom Galerie Aide

imgView.setLayoutParams(new mygallery.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
return imgView;
}
}
}
et le remplacement de onfling:
import android.content.Context;
import android.util.AttributeSet;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.widget.Gallery;
public class mygallery extends Gallery {
public mygallery(Context ctx, AttributeSet attrSet) {
super(ctx, attrSet);
// TODO Auto-generated constructor stub
}
private boolean isScrollingLeft(MotionEvent e1, MotionEvent e2){
return e2.getX() > e1.getX();
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY){
int kEvent;
if(isScrollingLeft(e1, e2)){ //Check if scrolling left
kEvent = KeyEvent.KEYCODE_DPAD_LEFT;
}
else{ //Otherwise scrolling right
kEvent = KeyEvent.KEYCODE_DPAD_RIGHT;
}
onKeyDown(kEvent, null);
return true;
}
}
