Bonjour tout le monde je travail sur une appli android qui fait le recadrage d'une image j'ai cherché un peu a droite a gauche sur internet et livre et voila ce que j'ai trouvé voir le code en dessous:  
 le probleme c'est que : eclipse me signale une erreur au niveau des portions de code en rouge (TextureImageDetailsActivity) et je sais pas comment les resoudre aidez mois svp a les resoudres  merci infiniment            
 
 
Code :
class ImageViewWithRectangle extends ImageView {
// Enable or not the cropping rectangle
private boolean hasCropRectangle = false;
// Cropping rectangle that we are drawing over the image
private RectF croppingRect = new RectF();
private RectF intialcroppingRect;

// Turns this boolean to false when we touch inside it
private boolean moveRectangle = false;
// Turns this boolean to true when we touch the border of the rectangle
private boolean resizeRectangle = false;
// Index of the corner that the user is currently dragging
private int sideIndex = -1;
// Maximum distance from a side to consider that we are touching it
private final float MAXDIST = 20;
// Minimum size of the cropping rectangle
private final int MINSIZE = 5;
// Values to deal with the touching
private float oldTouchValueX;
private float oldTouchValueY;
// This is the bounds of the drawable inside the image view
private RectF drawableRect;
